Question

Ajax请求不到jsp？急！！！代码如下，改js所在页面和请求的jsp在同一目录下，找不出url啥问题，alert报404

var XMLHttpReq;

function createXMLHttpRequest() {
if(window.XMLHttpRequest) { //Mozilla 浏览器
XMLHttpReq = new XMLHttpRequest();
}else if (window.ActiveXObject) { // IE浏览器
try {
XMLHttpReq = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
XMLHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
}

function getJobs(companyId){
var url = "getJobList.jsp?companyId="+companyId;
createXMLHttpRequest();
if(XMLHttpReq!=null){
XMLHttpReq.open("GET",url,true);
XMLHttpReq.onreadystatechange = complete;
XMLHttpReq.send(null);

}
}

function complete(){
if (XMLHttpReq.readyState == 4)
{
alert(XMLHttpReq.status);
if (XMLHttpReq.status == 200){
var result = XMLHttpReq.responseText;
}
}
}
必须是ajax

使用jquery，两行代码就搞定了
$.get("getJobList.jsp",{companyId:companyId},function(data){
alert(data);

});
当然，要引入jquery.js文件，自己下载去
