Name
Window.confirm( ): ask a yes-or-no question — JavaScript 1.0:
Synopsis
window.confirm(question)
Arguments
-
question The plain-text (not HTML) string to be displayed in the dialog box. It should generally express a question you want the user to answer.
Returns
true if the user clicks
the OK button; false if the user clicks the Cancel button.
Description
The confirm( ) method
displays the specified question in a
dialog box. The dialog box contains OK and Cancel buttons that the user can use to
answer the question. If the user clicks the OK button, confirm( ) returns true. If the user clicks Cancel, confirm(
) returns false.
The dialog box that is displayed by the confirm( ) method is
modal. That is, it blocks all user input to the
main browser window until the user dismisses the dialog box by
clicking on the OK or Cancel buttons. Since this method returns a
value depending on the user’s response to the dialog box, JavaScript
execution pauses in the call to confirm(
), and subsequent statements are not executed until the
user responds to the dialog box.
There is no way to change the labels that appear in the buttons of the dialog box (to make them read Yes and No, for example). Therefore, you should take care to phrase your question or message so that OK and Cancel are suitable responses.
