浏览器运行我们的脚本：
|

getcode(localStorage,"Storage")
|
|
生成：
|
|
Storage.prototype.length=0
|
|
Storage.prototype.clear= function clear(){debugger;};catvm.safefunction(Storage.prototype.clear);
|

Storage.prototype.getItem= function getItem(){debugger;};catvm.safefunction(Storage.prototype.getItem);

然后我们再具体实现每个方法
