看到一个基础ajax
function getResult(stateVal) {
var url = "servlet lectCityServlet?state="+stateVal;
if (window.XMLHttpRequest) {
req = new XMLHttpRequest();
}else if (window.ActiveXObject) {
req = new ActiveXObject("Microsoft.XMLHTTP");
}
if(req){
req.open("GET",url, true);
req.onreadystatechange = complete;
req.send(null);
}
}
function complete(){
if (req.readyState == 4) {
if (req.status == 200) {
var city = req.responseXML.getElementsByTagName("city");
file://alert(city.length);
var str=new Array();
&nbs
假如一个页面上有N个操作，都要用AJAX 不用控件，自己写JS
例如 <a href="#" onclick="">aaaa </a>
<a href="#" onclick= ......
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1&q ......
