Notes

The following text is shared between this article, DOM:window.prompt and DOM:window.alert Dialog boxes are modal windows - they prevent the user from accessing the rest of the program's interface until the dialog box is closed. For this reason, you should not overuse any function that creates a dialog box (or modal window).

Mozilla Chrome users (e.g. Firefox extensions) should use methods of nsIPromptService instead.

Requires Gecko 23.0 The argument is optional and not required by the spec.

Specification

Specified in HTML5.
