window.confirm

Summary

Displays a modal dialog with a message and two buttons, OK and Cancel.

Syntax

result = window.confirm(message);

• message is the string to be displayed in the dialog.
• result is a boolean value indicating whether OK or Cancel was selected (true means OK).

Example

if (window.confirm("Want to see my mood ring?")) { 
    window.open("mood.html", "mood ring", "");
}

Notes

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).

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

Specification
