Prompt dialog box showing app part URL as title

Hi,

I've SharePoint hosted app, which content one list and app part performing edit and delete operation.

Issue is when i prompt confirm dialog box in non-IE browsers(Firefox/Chrome) are show app url as title in confirm dialog box. I had tried adding Jquery dialog box plugins but issue all plugins based on div or html elements show custom dialog box popping up in iFrame instead of main site.

Is there any way to hide app URL from javascript confirm dialog?

Thanks
