Part 2.4Basic input methods in JavaScript

After covering the output methods of JavaScript, this article will cover the input methods of JavaScript.

Confirm dialog

The confirm dialog is a simple yes or no dialog and can be used to 'confirm' that a user wishes to proceed.

window.confirm("Do you wish to continue?");

Prompt dialog

If user input needs to be more than an OK or Cancel, the prompt dialog can be used. A prompt dialog provides the user with a textbox that allows them to input a response to the dialog:

window.alert(window.prompt("What is your name?"));

The prompt may optionally provide a placeholder:

window.alert(window.prompt("What is your name?", "Jamie Balfour"));

As with the alert method, both confirm and prompt are methods provided by the window and do not need window. in front of them.
