html5培训心得体会

html5培训心得体会html5培训心得体会1时间过得很快，从刚开始的培训开始到现在的培训结束，似乎都是眨眼间的事情。

首先很感谢任课老师莫老师和班主任以及其他腾科工作人员的工作付出，还有班级上共同学习进步的小伙伴们，让我顺利的学完了HTML5所有课程。

这次HTML5课程的学习让我学到了很多前端方面的知识，感觉自身的IT技术提升了不少。

此次课程培训让我对HTML5有了更加深入的了解。

HTML指的是超文本标记语言，标记语言是一套标记标签，HTML使用标记标签来描述网页。

HTML5区别于HTML的标准，基于全新的规则手册，提供了一些新的元素和属性，在web技术发展的过程中成为新的里程碑。

从市场来看，无论是桌面应用还是移动应用，HTML5都是当下Web技术中最炙手可热的新宠，是创新的主旋律，在不久的时间里一定会大有作为。

学习都是一步一个脚印，H5学习也是从前端开发的基础学起，首先学习使用HTML、CSS、Java、Jquery等一系列前端技术，实现一些网页动态效果。

再到后面的Vue。

js、bootstrap、Type等一些主流框架，还有微信小程序的'学习。

培训课程当然不是上课听懂就可以，而是必须能要去动手操作，达到熟练使用的要求和效果，为了保证学习效果，课程以理论和实例相结合的方式进行授课。

而且每个学习阶段的结束都会做一个实训项目，做项目不仅能是学到一些新知识，也能查缺补漏，巩固自己所学知识。

最好希望自己早日找到工作，在前端开发这条路上创造辉煌！html5培训心得体会2HTML5在网页开发上，赋予网页更好的意义和结构，更加丰富的标签将随着对RDFa的，微数据与微格式等方面的支持，构建对程序、对用户都更有价值的数据驱动的Web。

北京恒泰博远软件开发公司对HTML5的解释是，为开发者提供了一个跨平台的移动apps开发方案，并且该方案具有很好的扩展性和灵活性。

由目前it行业使用html5开发app来看，如今国内使用html5开发app应用技术尚有欠缺，因为在手机开发app上，html5应用只有两种方法，要不就是全使用HTML5的语法，要不就是仅使用JavaScript引擎。

AT42QT1010 电容触摸断开板使用指南说明书

AT42QT1010 Capacitive Touch Breakout Hookup GuideIntroductionIf you need to add user input without using a button, then a capacitive touchinterface might be the answer. The AT42QT1010 Capacitive TouchBreakout offers a single capacitive touch button with easy-to-use digital I/Opins.AT42QT1010 Breakout BoardThe AT42QT1010 is a dedicated, single-button capacitive sense chip. Thechip handles monitoring a conductive area for touch. As long as a touch(e.g. from a finger) is detected, the AT42QT1010 keeps the output line high.Otherwise, the line is kept low. You just need to provide a power source(1.8V - 5V) and ground for the AT42QT1010 to work. SparkFun’s breakoutboard contains an on-board electrode capable of detecting touches.Additionally, a PAD pin is available if you would like to create your ownexternal electrode.Covered In This TutorialThis tutorial will show you how to connect the AT42QT1010 Breakout Boardto an Arduino along with some example code to read the board’s output.Additionally, alternative ways to use the board will be shown, such asmounting it to an acrylic panel and creating your own capacitive sensingpad.Required Materials•AT42QT1010 Capacitive Touch Breakout Board•Arduino, RedBoard or any Arduino-compatible board.•4-Pin Male SMD header or Male PTH headers to make the boardbreadboard compatible.•Jumper wires to connect from breadboard to Arduino.•Breadboard to tie everything together.Suggested Reading•What is an Arduino?•How to Solder•Working with Wire•Switch Basics•Capacitors•LEDsBoard OverviewIf we look at the front of the board, we see a large, circular pad (the “electrode”) and several pins. The on-board electrode will detect touches when pressed with a finger as long as the board is powered.AT42QT1010 Breakout frontGND should be connected to the ground of the host circuit.OUT is the output of the AT42QT1010. HIGH on touch, LOW otherwise.VDD is the power supply for the AT42QT1010 and needs to be connected to a voltage between 1.8V - 5V.LED controls the operation of the on-board LED. By default, it is connected to the OUT pin. If you de-solder the “LED Enable” jumper on the back side, you can independently control the LED.PAD is located in the upper-left corner and allows you to connect to an external electrode. Note that there is a small surface mount pad on the back side by the PAD pin hole. If you want to mount the board flush, you can solder a wire directly to the surface mount pad.How It WorksTake a look at the back side of the board.AT42QT1010 Breakout backThe AT42QT1010 chip is located on the right side of the board. It uses a resistor and a capacitor network to adjust the sensitivity of the electrode. High frequency pulses are sent to the pad. When a fleshy object (such as a finger) approaches the pad, it acts like a very small capacitor and changes the shape of the pulses. When the AT42QT1010 detects these slight changes, it raises the OUT line to HIGH, indicating a touch is present. Once the pulses return to normal (i.e. the fleshy object is moved away from the pad), the AT42QT1010 drives the OUT line LOW.LED EnableThe output from the AT42QT1010 goes directly to the OUT pin on the board as well as to the transistor (left side), which operates the LED (center of board). By default, the OUT line and LED lines are connected, which means that on a touch, the on-board LED lights up. You can disconnect the LED by de-soldering the jumper labeled “LED Enable.” This will cause the LED to no longer light up on a touch, but you can still drive the LED using the LED pin on the board.ModeOn the right side of the board, you will also notice a jumper labeled “Mode” with “L” and “F” markers. By default, the center pad and the “F” pad are connected, which puts the AT42QT1010 in “Fast” mode. In Fast mode, the chip is more responsive to touch events but draws 200µA - 750µA in normal operation. If you de-solder this jumper and connect the center pad to the “L” pad, the AT42QT1010 will be in “Low Power” mode. In this mode, the chip is slightly less responsive to events but only uses 15µA - 75µA.Hookup ExampleAssemblyIf you are not planning to mount the board flush to a panel, you can solder either wires or break away headers to the 4 header holes on the board.PTH headers are recommended if you are using a breadboard.On the other hand, if you wish to mount the AT42QT1010 to a panel, you can solder a 4-pin male header to the SMD pads.SMD headers work better if you plan to mount the board to a panelConnecting the AT42QT1010 Breakout BoardBasic hookup using an Arduino and a breadboardFor an Arduino, make the following connections with jumper wires:(AT42QT1010 → Arduino)•VDD → 5V•OUT → 2•GND → GNDMounting the AT42QT1010 Breakout BoardOne advantage of capacitive touch boards is their ability to be mounted to panels and detect touch through thin plastic, cardboard, etc. Using a drill or laser cutter, cut four 0.125 inch holes in the same pattern as the mounting holes on the breakout board.Attach the board to the panel using #4-40 screws and #4-40 nuts.The AT42QT1010 will detect touch through 0.125 inch acrylic External ElectrodeYou can create your own electrode by using foil, copper tape, or any other conductive material. Cut or shape the electrode and attach a wire between the electrode and the PAD pin on the AT42QT1010 breakout board. The electrode can be almost any shape and size.Touch can be detected on external electrodesExample CodeOpen the Arduino program and paste the following code into the sketch:/*12232013SparkFun Electronics 2013Shawn HymelThis code is public domain but you buy me a beer if you use t hisand we meet someday (Beerware license).Description:This sketch shows how to use the SparkFun AT42QT1010 Breakout Board. If you touch the Capacitive Touch area on the breakout board, the LED attached to the Arduino will light up (in addi tionto the LED on the AT42QT1010 breakout board).Simply connect power and ground to the breakout board,and the AT42QT1010 handles all the capacitive touch function s.By default, the board will light up the green LED when the pa dis touched. A wire may also be connected from OUT on thebreakout board to a digital input pin on an Arduino. This sig nalis normally LOW but goes HIGH on a touch detection.The "LED Enable" solder jumper may be desoldered in order to control the LED directly from the LED pin. This is useful if youwant to light up a button that the user needs to push.Hardware connections:Uno Pin AT42QT1010 Board Function+5V VDD Power supplyGND GND Ground2 OUT Capacitive touch state output*/// Constantsconst int TOUCH_BUTTON_PIN =2; // Input pin for touch state const int LED_PIN =13; // Pin number for LED// Global Variablesint buttonState =0; // Variable for reading butto nvoid setup() {// Configure button pin as inputpinMode(TOUCH_BUTTON_PIN, INPUT);// Configure LED pin as outputpinMode(LED_PIN, OUTPUT);}void loop() {// Read the state of the capacitive touch boardbuttonState =digitalRead(TOUCH_BUTTON_PIN);// If a touch is detected, turn on the LEDif(buttonState ==HIGH) {digitalWrite(LED_PIN, HIGH);} else{digitalWrite(LED_PIN, LOW);}}Plug in the Arduino and upload the code. You should see the LED on theAT42QT1010 board and the LED on the Arduino light up when you touchthe electrode.The AT42QT1010 detects touches, and the Arduino monitors pin 2 for theoutput of the AT42QT1010.Resources and Going FurtherThe AT42QT1010 is a great way to add a single capacitive touch button toa project. For example:•Create a hidden button for the Illuminated Boxes.•Replace the Wake-On-Shake module with a capacitive touch buttonfor the Uncertain 7-Cube•Add a hidden, capacitive touch button to almost anything!If you need more than one capacitive touch button in your project, youmight want to look at some other products:•MPR121 Capacitive Touch Breakout•MPR121 Capacitive Touch Keypad•Touch ShieldResources•AT42QT1010 Datasheet•Secrets of a Successful QTouch Design•Breakout Board Schematic•Eagle and Project Files•GitHub Repositoryhttps:///tutorials/at42qt1010-capacitive-touch-breakout-hookup-guide?_...10/8/2015。

html学习总结

竭诚为您提供优质文档/双击可除html学习总结篇一：html学习总结1.hTmL标签由开始标签和结束标签组成，空的hTmL元素没有结束标签，比如没有内容的hTmL内容被称为空元素。

空元素是在开始标签中关闭的。

就是没有关闭标签的空元素（标签定义换行）。

在xhTmL、xmL以及未来版本的hTmL 中，所有元素必须被关闭。

在开始标签中添加斜杠，比如，是关闭空元素的正确方法，hTmL、xhTmL和xmL都接受这种方式。

即使在所有浏览器中都是有效的，但使用其实是更长远的保障。

2.hTmL标签及属性值对大小写不敏感：等同于。

w3school使用的是小写标签，因为万维网联盟（w3c）在hTmL4中推荐使用小写，而在未来(x)hTmL 版本中强制使用小写。

属性值应该始终被包括在引号内。

双引号是最常用的，不过使用单引号也没有问题。

在某些个别的情况下，比如属性值本身就含有双引号，那么您必须使用单引号，例如：name=bill"helloworld"gates3.标签在hTmL页面中创建水平线。

hr元素可用于分隔内容。

4.可定义一个地址（比如电子邮件地址）。

您应当使用它来定义地址、签名或者文档的作者身份。

SOFT 开发人员指南说明书

Simple Obfuscated File Transfer [SOFT] Developers GuideSOFT version 1.10SOFT is a utility that provides file transfer services. This guide provides information for developers who wish to build web page forms that use this service.Upload requests come via an HTTP POST request containing specific parameters. A download URL is returned to the user, which is then used to download what was uploaded.Calling SOFTSOFT must be called by an HTML web form with specific parameters (see below). The web form can be implemented on any web server, although certain helper-tools (server side includes) available for use in the forms will only work if the form is deployed on the same server as SOFT (i.e. the web servers used by Ministries of Environment, Agriculture and Lands, and the Environmental Assessment Office).The simplest code snip that would call SOFT looks like this:<form action="/perl/soft/ul.pl"method="post" enctype="multipart/form-data" ><p>File to Upload:<input type="file" name="_soft_filename" /></p><input type="submit" class="button"name="_soft_submit" value="Upload File" /></form>The form action points to SOFT. In the example above, the form is on the same server as SOFT. If the form is on a different server, then the form action would need to point to SOFT on the SOFT server (for example, form action=".bc.ca/perl/soft/ul.pl").Additional parameters can be used to control the behavior of SOFT or to collect business-specific information.SOFT ParametersSOFT looks for the POST parameters listed below. Any further parameters that begin with _soft_ are ignored. Any parameters that do not start with _soft_ are assumed to contain business information specific to the upload form, and are bundled into README.TXT and metadata.xml files that accompany the file for download.∙_soft_filename(mandatory): the file on the browser’s client to upload. If the file exce eds configured maximum filesize then an error is returned. If the file is unreadable or does not existthen an error is returned.∙_soft_mail_sendto (optional): an email address. If included and is valid then the system will send the recipient an email notification containing the URL of the uploaded file.∙_soft_mail_subject (optional): a subject line to use when sending the email. Default is something like: “A file is ready for download”. These metasymbols can be used in the subject: o[f] is replaced with the name of the uploaded file;o[s] is replaced with the size of the uploaded file (although the file, once zipped, may be significantly smaller on the server and when downloaded)<input type="hidden" name=_soft_mail_subjectvalue="File [f] is ready, size is [s]" />∙_soft_keep_days (optional): the number of days to retain the file before deleting from the transfer server. If the number of days exceeds the configured maximum then the maximum isused.∙_soft_force_gov (optional): Uploads from inside BC Government are by default available for download anywhere on the Internet. This parameter forces BC Gov uploads to be accessible only from within BC Gov, if it is set to any non-blank, non-zero value. This has no effect on uploadsfrom outside BC Gov.∙_soft_submit (mandatory): this is the name of the submit button.∙_soft_form_owner (optional but recommended): an email address of the person who maintains the web page containing the form. This allows notifications related to SOFT maintenance orchanges to go to business areas that rely on the service, and is only used by systems staff. E.g. <inputtype="hidden"name=_soft_form_ownervalue="**************.ca"/>∙_soft_forward_url (optional): if set, on success SOFT will forward (redirect) the browser to the given URL. The file download link will be added to the URL as a parameter soft_url. This isintended to allow SOFT to pass its success page to a custom page or to pass to an informationsystem for further processing. The ‘forward URL’ must be either HTTP or HTTPS, and reside on a .gov.bc.ca server. The URL may contain parameters, in which case the soft_url parameter isappended to the existing parameters.<input type="hidden" name=_soft_forward_urlvalue=”.bc.ca/int/myapp/catcher.do?datatype=treefrogs”>∙_soft_simple (optional): if set true (Y/y/1) then sets a parameter in the retrieval URL that makes SOFT return only the original file. If set false (N/n/0) then sets a parameter in the retrieval URL that makes SOFT return the complete archive including README.TXT and metadata.xml (ifavailable).o Note: a SOFT retrieval URL can force ‘simple’ download behavior by adding a parameter ‘simple=y’; or force full retrieval by adding a parameter ‘full=y’ (or simple=n). E.g.:http://big_long_soft_url?simple=y will force download of only the uploaded filehttp://big_long_soft_url?simple=n will force download of the full archive.There may be a performance advantage to ‘full’ where SOFT has compressed a file, as in‘simple’ mode downloads are not performed compressed.∙*other post parameters+: any other POST parameters are recorded in the archive’s README.TXT file. Truncation and scrubbing may take place to assure that content is not tainted or does notexceed reasonable content limits. Note that there are limits to the amount of information thatmay be included in POST parameters though they’re typically pretty generous. List items (e.g.from multi-picks) may or may not come through correctly [This is something to fix in a futurerelease if required].Server Side IncludesSOFT provides server-side includes that can be used in the creation of html forms.∙inside.pl–this returns a string saying if the user’s computer is inside or outside the BC∙force_gov.pl– if a user is outside the BC Gov, this does nothing. This returns a form element (radio button) to allow BC Government users to restrict access so that the uploaded file may bedownloaded only by BC Government (if, for example, the file were being sent betweenemployees). E.g.It is called using a server-side include like this:In order for a server side include to work, these conditions must be met:1)The web form must be on the same web server as SOFT, and the call to the include must notinclude a server name (see example above)2)The web form’s filename must end in .shtml instead of .html3)The directory containing the web form must have apache Includes enabled. This is done in theapache configuration file by adding Options +Includes for the area of the web server thatcontains the web form - contact IMB Web Hosting Services for support.“Uploading” animation/messageIt may be desirable to provide an animation or an “Uploading…” message while the fi le uploads. This is the responsibility of the web page that contains the web form. It is done using JavaScript, and in order to support the widest variety of browsers, this is the suggested implementation.When the user pressed the ‘Upload’ button, part of the screen (including the ‘Upload’ button) should disappear, and be replaced by text and possibly an animated image (GIF). For example:Becomes during upload, this (the form has been replaced by a message and an animation):In the HTML web form, this requires∙ A short JavaScript function.∙Use of <div> tags to surround the areas to be shown while the form is completed (“submission-area” in the example below) & shown while the upload takes place (“upload-msg-area” in theexample below).∙Modifications to the <form> and one of the <input> tags in the form.∙ A <noscript> section that will only be displayed if JavaScript is disabled in the browser. Example:The Javascript portion should go before the first <div> begins.<script type="text/javascript">// IE stops animating GIFs once a form Submit takes place, so// animated GIFs should be activated *after* the submit. Arrange this// by calling this function by means of a setTimeout() call. If the// setTimeout() is too short, then over slow connections it will still// be too soon.var showUploading = function() {document.getElementById('submission-area').style.display = 'none';document.getElementById('upload-msg-area').style.display = '';};</script>The first <div> identifies the area that will be visible while the user completes the form, and which will disappear when they press the ‘Upload’ button.In this example, the entire form is inside this first <div>. Notice that inside the form,1.An “onSubmit” has been added to the opening <form> tag.2.For the <input> element that provides the ‘Upload’ button, on onClick has been added:onclick="setTimeout(showUploading, 500);"<div id="submission-area"><form action="/perl/soft/ul.pl"method="post" enctype="multipart/form-data"onSubmit="document.getElementById('submission-area').style.display = 'none';" ><p>File to Upload: <input type="file" name="_soft_filename" /> </p><p>Comments to include with the file (optional):<br><textarea wrap="physical" cols="50" rows="2" name="comments"></textarea> </p><p>After the file uploads you can send emails containing a link to thefile from your own email account. </p><center><input type="submit" class="button"name="_soft_submit" value="Upload File"onclick="setTimeout(showUploading, 500);" /></center></form></div>In the “upload-msg-area” <div>, put contents that will be displayed only after the user presses the‘Upload’ button. In the example below, “wait4.gif” is the animated GIF image.<div id="upload-msg-area" style="display: none;"><center><h3>Please wait while your file uploads...</h3><p><img src="wait4.gif" alt="" /></p></center><p>Do not close your browser or interrupt the upload until it has finished. Upload may take a long time, depending on the size of the upload and your network speed. </p></div>The <noscript>section will only be displayed if the user’s browser has JavaScript disabled. It should warn them that not much will appear to happen after they cli ck ‘Upload’.<noscript><h3>Your browser has Javascript disabled. </h3><p>When you press the 'Upload File' button, there will be noindication that the upload is taking place; please wait and do not press the button a second time. </p></noscript>。

Android是以Linux为核心的手机操作平台，作为一款开放式的操作系统，随着Android的快速发展，如今已允许开发者使用多种编程语言来开发Android 应用程序，而不再是以前只能使用Java开发Android应用程序的单一局面，因而受到众多开发者的欢迎，成为真正意义上的开放式操作系统。

在Android中，开发者可以使用Java作为编程语言来开发应用程序，也可以通过NDK使用C/C++作为编程语言来开发应用程序，也可使用SL4A来使用其他各种脚本语言进行编程（如：python、lua、tcl、php等等），还有其他诸如：Qt（qt for android）、Mono（mono for android）等一些著名编程框架也开始支持Android编程，甚至通过MonoDroid，开发者还可以使用C#作为编程语言来开发应用程序。

另外，谷歌还在2009年特别发布了针对初学者的Android Simple 语言，该语言类似Basic语言。

而在网页编程语言方面，JavaScript，ajax，HTML5，jquery、sencha、dojo、mobl、PhoneGap等等都已经支持Android开发。

而在Android系统底层方面，Android使用C/C++作为开发语言。

应用程序（部分）早期的Android应用程序开发，通常通过Android SDK（Android软件开发包）下使用Java作为编程语言来开发应用程序，但通过不同的软件开发包，则使用的编程语言也不同。

例如开发者可以通过Android NDK（Android Native开发包）使用C语言或者C++语言来作为编程语言开发应用程序。

同时谷歌还推出了适合初学者编程使用的Simple语言，该语言类似微软公司的Visual Basic语言。

Sencha touch 开发指南本文主要介绍如何使用Sencha Touch为手持设备进行应用开发，主要是针对iPhone这样的高端手机，我们会通过一个详细的例子来介绍整个开发的流程。

Sencha Touch简介Sencha Touch是专门为移动设备开发应用的Javascrt框架。

通过Sencha Touch你可以创建非常像native app的web app，用户界面组件和数据管理全部基于HTML5和CSS3的web标准，全面兼容Android和Apple iOS。

如何使用Sencha Touch1 下载Sencha Touch包，并按照以下结构创建项目列表Sencha Touch包核心文件上图中加蓝色背景的图片为核心文件，必须载入。

2 创建HTML文件，引入以下CSS和Javascript文件view sourceprint?01.<!DOCTYPE html>02.<html>03.<head>04.<meta charset="utf-8">05.<title>Sencha Touch Test</title>06.07.08.<link rel="stylesheet" href="../../resources/css/sencha-touch.css" type="text/css">09.10.11.<link rel="stylesheet" href="css/guide.css" type="text/css">12.13.14.<script type="text/javascript" src="/maps/api/js?sensor=true"></script>15.16.17.<script type="text/javascript" src="../../sencha-touch-debug.js"></script>18.19.20.<script type="text/javascript" src="src/index.js"></script>21.22.</head>23.<body></body>24.</html>这样我们的HTML结构就搭建完成了。

3 使用Sencha Touch创建新的应用程序我们在这里使用一个电视内容查询的应用来详细介绍如何使用Sencha Touch来进行应用程序的开发。

我们首先使用Ext.setup方法来创建一个应用，你可以通过设置不同的参数来设置你的应用，具体的信息可以查阅API，查看Sencha Touch API Documentation。

代码如下：view sourceprint?1.Ext.setup({2.icon:'icon.png',3.tabletStartupScreen:'tablet_startup.png',4.phoneStartupScreen:'phone_startup.png',5.glossOnIcon:false,6.onReady:function() {7.}8.});在上面的程序里面我们需要注意onReady方法，它会在整个DOM结构载入可用的情况下调用里面的内容。

下面我们先在onReady下面创建一个TabPanel组件，并在其中添加我们需要的其他组件。

view sourceprint?01.var tabpanel =new Ext.TabPanel({02.tabBar: {// an Ext.TabBar configuration03.dock:'bottom',//the tabbar positionyout: {05.pack:'center' // the icon position06.}07.},08.fullscreen:true,//this component will take up the full width and height of the screen and automatically renders the component to the page09.cardSwitchAnimation: {10.type:'pop',11.cover:true12.},13.items: [{14.title:'Schedule',15.iconCls:'time',// the button icon16.cls:'card1',// an optional extra CSS class will be added to this component's element.17.id:'tab1',18.dockedItems: [{19.xtype:'toolbar',20.ui:'light',21.dock:'top',22.items: [Title ,24.{ xtype:'spacer' },25.{ text:'Change...', ui:'action', handler:function() {tvPicker.show();} },26.]27.}, {28.xtype:'panel',29.dock:'bottom',30.height: 48,31.html:''32.}],33.items: [List35.]36.}, {37.title:'About',38.html:'<table border="0" align="center" width="95%"><tr><td align="left"><br />'39.+'<h1>Sport on TV</h1><br />Version 1.0 for iPhone<br />Using <a style="color:#000;text-decoration:none;" href="/">Sencha Touch</a> framework.<br /><br /><br />'40.+'<h1>Help</h1><br />Instantly discover what, when and where there is live sport on TV in the UK. (All times are GMT.)<br />To browse the schedule, tap <strong>Change...</strong> and select a sport and TV network. For additional information, tap the fixture.<br /><br /><br />'41.+'<h1>Disclaimer</h1><br />Although every effort is made to ensure schedule information provided within the app is accurate, we can make no guarantee that it is always correct and can not accept responsibility for inaccurate information. Please double-check any fixtures that are important to you to avoid disappointment. Please also note that this app does not claim to stream video; it is a tool to display schedules of live sporting events on TV in the UK.<br /><br /><br />',42.cls:'card4',43.styleHtmlContent:true,44.iconCls:'info',45.id:'tab2'46.}]47.});48.Store.load();fullscreen这个参数是用来设置“首页”的，就是把当前的组件设置成为用户最先看到的组件。

Items是用来设置该组件下面的具体内容。

可以添加另外的组件到该组件下，使整个页面可以灵活组合，实现各种功能。

在上面的代码中我们在schedule这个tab下面又添加了tvList和tvTitle这两个组件，tvList 用来显示后台传递过来的数据，tvTitle用来显示当前的类别，我们会在下面做详细的介绍。

最下面我们调用了tvStore.load()，这里是使用了Ext.data.Store组件，来读取后台的数据。
