先看一下效果图：
代码如下：

} });
//实例化Model、ViewRight、ViewLeft
var model = new Model();
var viewRight = new ViewRight({model : model});
var viewLeft = new ViewLeft({model : model, viewRight : viewRight});
viewLeft.getFolder();
</script> </html>
只要再引入jquery.min.js、underscore.js、backbone.js。然后用fiddler挂载这几个文件，从139邮箱登陆页登陆进去即可看到效果。
