jQuery Contra Code

Easily create customizable Contra Code style Easter-eggs in your web application.

Usage

Getting up and running is really easy!

$.contra(config);

Example

$.contra({
    begin: function() {
        console.log("The user has begun entering the contra code.");
    },
    fail: function() {
        console.log("Fail!");
    },
    success: function() {
        alert("You're a genius!");
    }
});

Configuration

jQuery Contra contains a few options which allow you to customize many aspects of it.

• config.scope - The scope in which to bind key presses to.
• config.code - Array of keycodes to step through.
• config.time - The amount of time in milliseconds that the user must press the next key in the sequence. Optionally, if there is no timeout, use false.

jQuery Contra also supports a few optional callback functions. These are useful in a couple of scenarios:

1. Tracking successful Contra codes.
2. Tracking the fail rate.
3. Performing actions before the contra code is completed/failed.

The callback functions are:

• config.fail - Called when the user has started entering the Contra code, but failed to hit the next key in the sequence correctly.
• config.success - After the keycodes have been successfully entered, this will be called.
• config.begin - This is called after the user hits the first key in the sequence.
