重写XMLHttpRequest并模拟响应

Question

Would it be possible to override XMLHttpRequest and emulate response from a callback ?

Something like :

 window.XMLHttpRequest.prototype.open = function() { var url = arguments[1]; if (url === 'someUrl' && isOnline === false){ //Return a fake reponse to the request... } ... } 

It would be realy nice to do this in my phonegap app, so if the user is offline I could retrieve the response from my local sqlite db.

解决的办法是使用嘲笑插件。
