（以上代码出处 http://res.wx.qq.com/connect/zh_CN/htmledition/js/wxLogin.js ） 微信三方登录的一个js文件，我尝试改写成coolie的模块总是提示有错，请问这种具体要如何改写呢？ 正常情况下是这样实例化的，

 var obj = new WxLogin({
                        id:"wxLoginQRCode",
                        appid: load.thirdLoginRequestJsonData.WeChat.WeiXinAppId,
                        scope: load.thirdLoginRequestJsonData.WeChat.WeiXinScope,
                        redirect_uri: load.thirdLoginRequestJsonData.WeChat.WeiXinRedirectUrl,
                        state: load.thirdLoginRequestJsonData.WeChat.WeiXinState,
                        style: load.thirdLoginRequestJsonData.WeChat.WeiXinStyle,
                        href: load.thirdLoginRequestJsonData.WeChat.WeiXinHref
                    });
