两个封装的比较好的AJAX函数

    if (window.ActiveXObject) {
        try {
            xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
        }

function sendAJAX(url, pars, method, onComplete, asynchronous, cachecontrol) {
    createXMLHttpRequest();
   
    xmlHttp.onreadystatechange = function() {
        if (xmlHttp.readyState == 4) {
            if (xmlHttp.status == 200) {
                //此处可对应更改为xmlHttp.responseXML和xmlHttp.responseStream
                onComplete(xmlHttp.responseText);
            }
            else {
                alert("there is an error in server!the status is:" + xmlHttp.status.toString());
            }
        }
    }
 
   

    if (method.toLowerCase() == "get") {
        if (!cachecontrol) {
            if (pars != "") {
                pars += "&time=" + new Date().toString();
            }
            else {
                pars += "?time=" + new Date().toString();
            }
        }
       
        if (pars != "") {
            url += "?" + pars;
        }
        xmlHttp.open("GET", url, asynchronous);
        xmlHttp.send(null);
    }
    else {
        if (!cachecontrol) {
                url += "?time=" + new Date().toString();
        }
        xmlHttp.open("POST", url, asynchronous);
        xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");//必须加，否则后台取不到数据
        xmlHttp.send(pars);
    }
}

调用方式：

引用该js文件后直接使用

sendAJAX("AjaxTest.ashx", "id=1", "post", onComplete, true, false);

即可，onComplete是处理后台取来的数据函数
