<mce:script type="text/javascript" language="javascript"><!--// src http://woooh.com/post/learn_ajax.htmlvar http_request = false;function sendRequest(url, obj) { http_request = false; if (window.XMLHttpRequest) { // Mozilla, Safari,... http_request = new XMLHttpRequest(); if (http_request.overrideMimeType) { http_request.overrideMimeType('text/xml'); } } else if (window.ActiveXObject) { // IE try { http_request = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { http_request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} } } if (!http_request) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } http_request.onreadystatechange = function processRequest() { //最后输出过程 if (http_request.readyState == 4) { if (http_request.status == 200) { document.getElementById(obj).innerHTML=http_request.responseText; //alert(http_request.responseText); } else { alert('There was a problem with the request.'); } } } document.getElementById(obj).innerHTML="waiting..."; http_request.open('GET', url, true); http_request.send(null);}// --></mce:script>
