Question

I have done something like this a long time ago where I captured the alerts and prevented the default browser based alert box from popping up and replaced it with a modal of one kind or another. However its been so long since I have done that, and I can’t find any reference from old code of mine how I did it, nor can I find anything relevant via google currently. So.. I am hoping someone here can aid me in this and help me out. I havent tried anything yet so save yourself the question of what did I try. Other than spending the last hour or so googling different phrases for any snipplet of code that resembles whats in my blurry memory I’ve come up empty handed. I know, this is kind of a poor quality question to, but at the same time I am sure others would appreciate knowing the answer as well.

All I want to do in my case is capture the event that would trigger the alert() box and pass the message that was in it to another variation of notification. Currently I am doing some work in appmobi with a couple others and I want to take alert() capture it then use

AppMobi.notification.alert(message,title,buttontext); as the default action for alert()

You can simply overwrite the alert method:

window.alert = function(msg) {
   // whatever you want to do with 'msg' here
};

Note that this won’t have the blocking behavior of a regular alert
