javascript调用ajax页面返回指定内容

Ajaxjs.js页面

///调用方法，返回指定的内容

function Ajax(url)

{

var m_xmlReq=null;

if(window.ActiveXObject)

{

try

{

m_xmlReq = new ActiveXObject('Msxml2.XMLHTTP');

}

catch(e)

{

try{m_xmlReq = new ActiveXObject('Microsoft.XMLHTTP');}catch(e){}

}

}

else if(window.XMLHttpRequest)

{

m_xmlReq = new XMLHttpRequest();

}

this.post=function(d)

{

if(!m_xmlReq) return;

m_xmlReq.open('POST',url,false);

m_xmlReq.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded;charset=utf-8');

m_xmlReq.send(d);

//return eval("("+m_xmlReq.responseText+")"); //成功

return m_xmlReq.responseText;

}

}

index.aspx页面

<script type="text/javascript">

function getAjax() {

var checker_ajax1 = new Ajax("Handler1.ashx");

var param = "resumeId=" + $("Text1").value;

var temp1 = checker_ajax1.post(param);

alert("temp1为返回来的值："+temp1);

}

</script>

一般处理程序页面：Handler1.ashx

返回得到的值 context.Response.Write(context.Request["resumeId"]);
