WMLScript Standard Libraries: The Dialogs Library

WMLScript Standard Libraries

The Dialogs Library

This library contains a set of user interface functions, similar to the message boxes of JavaScript.

prompt()

This function displays a given message and prompts for an input. A default input is also specified as the second parameter. Returns the user input.

Syntax	prompt(message, defaultInput)
Parameters	message = String, defaultInput = String
Returns	String or invalid
Examples:	var a = Dialogs.prompt("Enter number of years for computing the mortgage:", "8"); // a = "12"

confirm()

This function displays a given message and waits for the user to select one of the reply alternatives: ok and cancel. Returns true for ok and false for cancel. The ok and cancel strings have implementation-dependent defaults and are programmable by this function.

Syntax	confirm(message, okMessage, cancelMessage)
Parameters	message = String, okMessage = String, cancelMessage = String
Returns	Boolean or invalid
Examples:	var a = Dialogs.confirm("Delete Entry?", "Yes", "Later"); // a = true ("Yes" is selected)

alert()

This function displays the given message, waits for the user to confirm, and then returns an empty string.

Syntax	confirm(message)
Parameters	message = String
Returns	String or invalid
Examples:	var a = Dialogs.alert("Number of years for mortgages must be less than 25!"); // a = ""
