PHP页面跳转

1，使用页面跳转完成，在点击选项后使用JavaScript控制跳转到的页面（简单）2，使用Ajax技术（难），不用跳转，但是要自己绘制表格Javascript代码：function selectcontest(ID)//这里改成点击选项后的Onchange（）函数{document.getElementById('statuscheck').disabled=false;if(document.getElementById('selectcontest').value!=0){openstatus(1);var s="../control/getteamscore.php?from="+0+"&ContestID="+ID;//这是请求数据的页面，在这里面从数据库提取数据var xmlHttp=createXmlHttp();xmlHttp.onreadystatechange=function(){if(xmlHttp.readyState==4||xmlHttp.readyState==0||xmlHttp.status==0){var r=xmlHttp.responseText;//alert(r);var n=r.split('^')[0];var ProblemName=r.split('^')[1];var team=r.split('^')[2].split("*");//队伍及各题成绩var num=team.length-1;//队伍数var i=0;var tablenode=document.getElementById('scorecheck');var u=tablenode.rows.length;var q=3;while(q<=u){tablenode.deleteRow(-1);q++;}//alert(n);//tablenode.rows(0).cells(2).colSpan="5";var nnode=document.getElementById('dati');nnode.colSpan=n;//alert(n);tablenode.deleteRow(1);//tablenode.rows(1).removeChild(tb.rows(1).cells(0));//alert(n);tablenode.insertRow(1);var ProblemNameArray=new Array();while(i<n){var ProblemNamesplit=ProblemName.split("=")[i];//alert(ProblemNamesplit);var Problem_Name=ProblemNamesplit.split("&")[0];var Problem_score=ProblemNamesplit.split("&")[1];var Detuct_score=ProblemNamesplit.split("&")[2];//alert(Detuct_score);var x=tablenode.rows[1];var cell = x.insertCell(i);ProblemNameArray[i]=Problem_Name;cell.innerHTML=""+Problem_Name+"-<fontsize=\"2\">"+Problem_score+"-</font>"+"<font size=\"2\" color='red'>"+Detuct_score+"</font>";i++;}i=0;//alert(num);while(i<=num){var scoreall=0;var teamdetail=team[i].split("#")[0];//代号加队伍名称var teamID=teamdetail.split("@")[0];//队伍代号//alert(teamID);var teamName='';teamName=teamdetail.split("@")[1];//队伍名称if(typeof(teamName) =="undefined")teamName='无注册人员';tablenode.insertRow(i+2);var x=tablenode.rows[i+2];var cell=x.insertCell(0);cell.innerHTML="<b>"+teamID+"</b>";cell=x.insertCell(1);cell.innerHTML="<b>"+teamName+"</b>";var problemscore=team[i].split("#")[1];//题号加成绩if(problemscore){var problem_ID_all=problemscore.split("=");var t=0;//alert(n);while(t<=n){//alert(t);cell=x.insertCell(t+2);cell.innerHTML="0";t++;}var m=problem_ID_all.length;//答题的数目//alert(problem_ID_all.split('&'))//alert(n);t=0;while(t<m){var problem_ID=problem_ID_all[t].split("&")[0];var problem_ID_score=problem_ID_all[t].split("&")[1];var w=0;while(w<n){if(problem_ID==ProblemNameArray[w]) tablenode.rows[i+2].cells[w+2].innerHTML=problem_ID_score;w++;}if(problem_ID_score>0)scoreall+=parseInt(problem_ID_score);t++;}var scorecell=parseInt(n)+2;tablenode.rows[i+2].cells[scorecell].innerHTML=scoreall;}else{var t=0;while(t<=n){//alert(t);cell=x.insertCell(t+2);cell.innerHTML="0";t++;}}i++;}}}s=s+"&"+Math.random();xmlHttp.open("GET",s,true);xmlHttp.send(null);}else{document.getElementById('statuscheck').disabled=true;document.getElementById('statusspan').innerHTML="";}}function createXmlHttp()//创建ajax{try{// Firefox, Opera 8.0+, Safarivar xmlHttp=new XMLHttpRequest();}catch (e){// Internet Explorertry{xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");}catch (e){try{xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");}catch (e){alert("您的浏览器不支持AJAX！");return false;}}}return xmlHttp;}getteamscore.php代码<?phpheader('Content-Type:text/html;charset=GB2312');include("../acmDBcoon.php");$from=$_GET['from'];$ContestID=$_GET['ContestID'];$query="select count(*) from contestteam where ContestID=$ContestID";$result=@mysql_query($query);$row=@mysql_fetch_array($result);$countteam=$row[0];$query="select UserID,NickName from user where ContestID like '%C".$ContestID."C%' limit $from,20";//echo $query;//echo "<br/>";$result=@mysql_query($query);$str="";while($row=@mysql_fetch_array($result))//每个用户的循环{$UserID=$row['UserID'];//$str.=$UserID.'#';//$query2="select TeamName from contestteam where TeamID='$UserID'";//$result2=@mysql_query($query2);//$row2=@mysql_fetch_array($result2);$str.=$row['UserID']."@".$row['NickName'].'#';//@为队伍代号与队伍名称之间的分割$query1="select * from score where ContestID=$ContestID and UserID='$UserID'"; $result1=@mysql_query($query1);while($row1=@mysql_fetch_array($result1)){$str.=$row1['ProblemID'].'&'.$row1['score'].'=';//&为题号与得分之间的间隔符，=为题目之间间隔符}$str=substr($str,0,-1);//去除最后一个‘=’号$str.='*';//*号为用户之间的结束符}$str=substr($str,0,-1);$query3="select ProblemsName from contest where ContestID=$ContestID";$result3=@mysql_query($query3);$row3=@mysql_fetch_array($result3);$ProblemName=$row3[0];$problem1=split('=',$ProblemName);$str=count($problem1)."^".$ProblemName."^".$str;//^为题目数目与其他内容的间隔 echo $str;?>。
