Changing the default title of confirm() in JavaScript?


Is it possible to modify the title of the message box the confirm() function opens in JavaScript?

I could create a modal popup box, but I would like to do this as minimalistic as possible. I would like to do something like this:

confirm("This is the content of the message box", "Modified title");

The default title in Internet Explorer is "Windows Internet Explorer" and in Firefox it's "[JavaScript-program]." Not very informative. Though I can understand from a browser security stand point that you shouldn't be able to do this.

This is not possible, as you say, from a security stand point. The only way you could simulate it, is by creating a modeless dialog window.

There are many third-party javascript-plugins that you could use to fake this effect so you do not have to write all that code.

YES YOU CAN do it!! It's a little tricky way ; ) (it almost works on ios)

var iframe = document.createElement("IFRAME");
iframe.setAttribute("src", 'data:text/plain,');
if(window.frames[0].window.confirm("Are you sure?")){
    // what to do if answer "YES"
    // what to do if answer "NO"

Enjoy it!

Not possible. You can however use a third party javascript library that emulates a popup window, and it will probably look better as well and be less intrusive.

You can always use a hidden div and use javascript to "popup" the div and have buttons that are like yes and or no. Pretty easy stuff to do.

Yes, this is impossible to modify the title of it. If you still want to have your own title, you can try to use other pop-up windows instead.

I know this is not possible for alert(), so I guess it is not possible for confirm either. Reason is security: it is not allowed for you to change it so you wouldn't present yourself as some system process or something.

You can't unfortunately. The only way is to simulate this with a call.

Don't use the confirm() dialog then... easy to use a custom dialog from prototype/scriptaculous, YUI, jQuery ... there's plenty out there.
