原标题:Is there a way to clone native functions in javascript like window.alert or document.write

我想要做的是,将守则中的每一警示改变为习惯警示(“青年使用的警示”)。

var hardCodedAlert = alert; //I know this won t work.But what to do ?
window.alert=function(){
if(this.count == undefined)
this.count=0;
this.count=this.count+1;
if(this.count == 1)
hardCodedAlert("You used alert");
};
问题回答

是的。

var oldalert = window.alert;
window.alert= function alert(t){
  alert.count = !alert.count ? 1 : alert.count + 1;
  oldalert(t+  - That s alert nr  +alert.count);
};
