Name
Window.prompt( ): get user input with a dialog box â JavaScript 1.0:
Synopsis
window
.prompt(message
,default
)
Arguments
-
message
The plain-text (not HTML) string to be displayed in the dialog box. It should ask the user to enter the information you want.
-
default
A string that is displayed as the default input in the dialog box. Pass the empty string (
""
) to makeprompt( )
display an empty input box.
Returns
The string entered by the user, the empty string if the user
did not enter a string, or null
if the user clicked Cancel.
Description
The prompt( )
method
displays the specified message
in a
dialog box that also contains a text input field and OK and Cancel buttons. Platform-dependent graphics
in the dialog box help indicate to the user that her input is
desired.
If the user clicks the Cancel button, prompt( )
returns null
. If the user clicks the OK button, prompt(
)
returns the text currently displayed in the input
field.
The dialog box that is displayed by the prompt( )
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 userâs response to the dialog box, JavaScript
execution pauses in the call to prompt(
)
, and subsequent statements are not executed until the
user responds to the dialog box.
