function loadXMLDoc(idName,url,sendOut) { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById(idName).innerHTML=xmlhttp.responseText; } } xmlhttp.open("POST",url,true); xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded"); xmlhttp.send(sendOut); }
其中idName是要显示接收内容的元素id,url是要链接的远程文件地址,sendOut发送的内容。
