<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/jsp");
            }
        }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！');
                }
            }
        }
    }
