我的AJAX调用没有返回任何东西，但也没有失败-MyAJAXcallisnotreturninganythingbutisn'tfailingeither

I have this html:

我有这个HTML：

and this Javascript:

这个Javascript：

var xmlHttp;
document.body.Onclick= function(){
    var username = document.getElementById('text').value;
    selectUser(username);
}
    function selectUser(username){
        var url = "http://twitter.com/statuses/user_timeline/" + username + ".json?callback=twitterCallback2&count=100";
        try{// Opera 8.0+, Firefox, Safari
            xmlHttp = new XMLHttpRequest();
        }catch (e){// IE
            try{
                xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
            } catch (e) {
                try{
                    xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
                } catch (e){
                    // Something went wrong
                    alert("Your browser broke!");
                    return false;
                }
            }
        }
        xmlHttp.Onreadystatechange= processRequest;
        xmlHttp.open( "GET", url, true );
        xmlHttp.send( null );
    }

    function processRequest(){
        if ((xmlHttp.readyState == 4) && (xmlHttp.status == 200)) {
            if ( xmlHttp.respOnseText== "Not found" ) {
                document.getElementById('twitter_update_list').innerHtml = "Not found";
            }else if(xmlHttp.respOnseText== " "){
                document.getElementById('twitter_update_list').value = "Empty";
            }else{
                // No parsing necessary with JSON!        
                document.getElementById('twitter_update_list').value = xmlHttp.responseText;
                console.log(xmlHttp.responseText);
            }
        }
    }

I am looking at firebug and I see verything gets sent correctly but I don't get any response whatsoever. Oh, and I'm using raw Javascript because I want to practice it. =)

我正在看萤火虫，我看到正确发送的东西，但我没有得到任何回应。哦，我正在使用原始的Javascript，因为我想练习它。 =）

$.load("http://twitter.com/statuses/user_timeline/"+username,
function(data)
{
alert(data);
}
);
