Dynamic HTML: The Definitive Reference

Name

confirm( ) — NN 2 IE 3 DOM n/a

Synopsis

confirm(message)

Displays a dialog box with a message and two clickable buttons. One button indicates a Cancel operation; the other button indicates the user’s approval (OK or Yes). The text of the buttons is not scriptable. The message should ask a question to which either button would be a logical reply. A click of the Cancel button returns a value of false; a click of the OK button returns a value of true.

Because this method returns a Boolean value, you can use this method inside a condition expression:

if (confirm("Reset the entire form?")) {
    document.forms[0].reset( )
}

Returned Value

Boolean value: true | false.

Parameters

message

Any string, usually in the form of a question.
