Change the native confirm/alert [duplicate]

Answer 1

You mean alert? You can't control/remove the title from javascript alert.

Answer 2

You can't because confirm is a javascript function which you can't change. Might want to consider using other solution like a modal window where you can add custom header/title and stuff.

Answer 3

You can't control the appearance of confirm() or alert() Javascript popups, because they are native controls, so their appearance is based on the OS and the browser.

What you can do:

• create your own Javascript dialog
• use a pre-written dialog like jQuery UI's dialog
• if you don't want to include a full library (like jQuery UI) for a simple dialog, try something like javascript-simple-dialog
