Javascript - Change Message Box Title

how can i change the title of message box in java script plese given me a code for that

Solution 1:

You can not change for standard alert() of javascript.

go through this link- http://labs.abeautifulsite.net/projects/js/jquery/alerts/demo/

Solution 2:

If you are using the native alert(), you can't. It is browser implemented.

If using a custom modal, simply change the HTML as you would any other element.
