How to disable dialog boxes - alert()?

I have a page where I'm displaying iframes. The iframes are on the same domain with the website so I can edit and read the content of it, but I can't edit the source code of the iframes, because I don't have access to the file itself. The iframes are alerting a message and I want to disable this. I want to disable the dialog boxes at least for myself, I`m using chrome...

Is this possible without disabling javascript ? Or could I disable javascript only inside the iframes ?

Answer

What about:

window.frames[0].alert = function() {};

It overwrites the alert function inside the first iframe with a function that does nothing, hence all alert(...) calls called there result in nothing happening.

As for subsequent iframes, you'd need to change 0 into 1 etc.
