代码如下：

 SendHttpRequest(serverUrl, rType, callBack, data){
    if ( undefined == rType ){
        rType = "GET";
    }
    var url = serverUrl;

    //每次都实例化一个，否则会引起请求结束，实例被释放了
    var httpRequest = new XMLHttpRequest();

    //服务器json解码
    var self = this;
    httpRequest.onerror = function(){
        console.log("httpRequest.error1:", url);
    };

    httpRequest.onreadystatechange = function(){
        //执行成功
        if (httpRequest.readyState == 4 && (httpRequest.status >= 200 && httpRequest.status < 400)) {
            var response = httpRequest.responseText;
            // console.log(httpRequest.responseText);
            if ( undefined != callBack) {
                callBack(httpRequest.responseText);
            }
        } else{
            console.log("httpRequest.error status : %s", httpRequest.status);
            // self.onHttpError();
        }
    };
    httpRequest.open(rType, url, true);

    if ( data )
        httpRequest.send(data);
    else
        httpRequest.send();
}

麻烦大神帮忙看下。。
