tempXHR.readyState 始终返回：1，代码如下，哪位大牛帮忙看看代码哪个地方有问题？谢谢！！！

var tempStr="";
var tempXHR=cc.loader.getXMLHttpRequest();
tempXHR.open(“GET”, “http://192.168.1.199/testcc.aspx?type=cc”, true);//返回：CC
tempXHR.onreadystatechange=function(){
if(tempXHR.readyState == 4){
tempStr = tempXHR.responseText;

        }
    };
    tempXHR.send();        
    var tempWinsize = cc.director.getWinSize();
    var child301 = cc.LabelTTF(tempStr, "新宋体", 16);
    this.addChild(child301);
    child301.x = tempWinsize.width / 2;
    child301.y = 245;
