防止跨域方式调用JS

<script type="text/javascript">

        document.domain = "aaa.com";

        if (typeof (bitLoadScript) == "undefined")
            bitLoadScript = function (url, callback, charset) {
                var s = document.createElement("script");
                s.type = "text/javascript";
                if (charset) s.charset = charset;
                if (s.readyState) {
                    s.onreadystatechange = function () {
                        if (s.readyState == "loaded" || s.readyState == "complete")
                        { s.onreadystatechange = null; if (callback) callback(); }
                    };
                }
                else {
                    s.onload = function () {
                        if (callback) callback();
                    };
                }
                s.src = url;
                document.getElementsByTagName("head")[0].appendChild(s);

            };

//           调用

//            bitLoadScript("http://aaa.com/ssss.ashx", null, "utf-8");

//            bitLoadScript("http://aaa.com/ssss.js?v=3.0", null, "utf-8");

//     重复调用
bitLoadScript("http://aaa.com/201001/usercars.js",
function(){
viewedcars();
bitLoadScript("http://aaa.com/201001/usercarlife.js",function(){bitLoadScript("http://aaa.com/bitautoforum/userforum.js",usercarlife ,"utf-8");},"utf-8");},"utf-8");
