/* 以下代码通过ajax实现在一个web页面点击不同的链接,然后将返回的结果显示在该页面固定的div里。 */
<html>
<head>
<Meta charset="UTF-8">
<title>Insert title here</title>
<script language="javascript">
var http_request = false;
function createRequest(url,objID){
	http_request = false;
	if(window.XMLHttpRequest){ //非IE浏览器
		http_request = new XMLHttpRequest();
		if(http_request.overrideMimeType){
			http_request.overrideMimeType("text/xml");
		}
	}else if(window.ActiveXObject){ //IE浏览器
		try{
			http_request = new ActiveXObject("Msxml2.XMLHTTP");
		}catch(e){
			try{
				http_request = new ActiveXObject("Microsoft.XMLHTTP");
			}catch(e){}
		}
	}
	if(!http_request){
		alert("无法创建XMLHTTP实例");
		return false;
	}
	http_request.open("GET",url,true);
	http_request.send(null);

	var obj = document.getElementById(objID);
	http_request.onreadystatechange = function(){
		if(http_request.readyState == 4){
			if(http_request.status == 200){
				obj.innerHTML = http_request.responseText;
			}else{
				alert('您请求的页面发现错误!');
			}
		}
	}
}
</script>
