Mootool ajax readystate响应总是1?

我一直试图让这个mootools(版本:1.2.4)类来处理我的ajax请求。但我的脚本只返回readystate 1.永远不会到2,3或4,方法handleHttpResponse似乎只运行一次。我会看到提醒,我只得到1.任何想法?

var replyXML = new Class ({
    /* GDW AJAX REQUEST SCRIPT */
    /* By: Jonathan Robidas 2011-05-13 */
    initialize : function(url){
        this.http = this.getHTTPObject();   // We create the HTTP Object
        this.url = url;                                     // Requested server-side script
        this.response = '';                             // String returned by AJAX, Set after positive response
    },
    returnResponse : function() {
        return this.response;
    },
    handleHttpResponse : function() {
        alert(this.http.readyState);
        if (this.http.readyState == 4) {
            if(this.http.status==200) {
                alert("YA YA 2");
                this.response = this.http.responseText;
                return true;
            }
        }
    },
    requestXML : function() {
        this.http.open("GET", this.url, true);
        //this.http.onreadystateshange = this.handleHttpResponse();
        this.http.onload = this.handleHttpResponse();
    },
    getHTTPObject : function() {
        var xmlhttp;
        if(window.XMLHttpRequest){
            xmlhttp = new XMLHttpRequest();
        }
        else if (window.ActiveXObject){
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
            if (!xmlhttp){
                xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");
            }
        }
        return xmlhttp;
    }
});

这就是我现在推出的方式。我的内容为null但我的url是一个有效的XML文件。所以它不应该是空白的......?

<script language="Javascript" type="text/Javascript">
    window.addEvent('domready', function() {
        loadXML = new replyXML('gdwcommreply_genxml.php?getfield=idvideo&fieldid=64&parentid=59');
        loadXML.requestXML();
        content = loadXML.returnResponse();
        alert(content);
        /*
        x=content.documentElement.childNodes;
        for (i=0;i<x.length;i++) {
            document.write(x[i].nodeName);
            document.write(": ");
            document.write(x[i].childNodes[0].nodeValue);
            document.write("<br />");
        }
        */
    });
</script>

在Google Chrome,Firefox 4,Internet Explorer 7&amp; 8,都是一样的结果。 以下是脚本输出的XML示例:http://jerenovici.net/gdwcommreply_genxml.php?getfield=idvideo&fieldid=64&parentid=59所以我知道我生成xml的php很好。

谢谢!

你为什么要重新发明轮子?如果您正在使用mootools,那么发出ajax请求非常容易(docs,指的是最新版本,但在这种情况下请求没有更改):

new Request({
    url : './gdwcommreply_genxml.php?getfield=idvideo&fieldid=64&parentid=59',
    onSuccess : function(responseText, responseXML){

        /* here, do stuff with your response */

    },
    onFailure : function(xhr){

        /* the XMLHttpRequest instance. */

    }
}).send();

然后,你确定网址是否正确?
