覆盖警报并在Javascript中确认 [英] Override alert and confirm in Javascript

问题描述

有没有办法在javascript中覆盖 alert（）和 confirm（）？

Is there a way to override alert("") and confirm("") in javascript?

我使用jQuery，所以如果有办法在这个框架中做到这一点，我会很感激。

I use jQuery, so if there is a way to do it in this framework, I'd appreciate it.

我想做的事情如下：

override alert(msg){
    //Show custom stuff here
}

override confirm(msg){
    //Show custom stuff here.
    return watever;
}

推荐答案

是和否。你可以简单地替换它们：

Yes and no. You can simply replace them:

window.alert = function(msg){
    // stuff
}

但是你不会得到提醒和确认给你的阻止功能，即那里将无法使此代码正常工作：

but you're not going to get the blocking functionality that alert and confirm give you, i.e. there will be NO way to get this code to work:

if(confirm('Do Something?')){
   // do stuff
}

你通常最好不要做其他功能与你试图取代这些相似的东西。

You're generally better off making other functions to do similar things than you are trying to replace these.
