jQuery plugin designed to type text out to the browser character by character. A lot of available options.
JavaScript

README.md

jquery.coolType is a JQuery plugin that inserts a string into an element one character at a time, giving a unique typing effect.

Usage

<script type="text/javascript" src="/scripts/jquery.min.js"></script>
<script type="text/javascript" src="/scripts/jquery.coolType.js"></script>

Default Options

Using jquery.coolType with default options is extremely simple.

var msg = 'This line is being typed out character by character with the default coolType options.';
$('body').coolType(msg);

Custom Options

It is possible to get finer control over how the text is typed if you supply custom options. All values in the sample below are the default values.

var msg = 'This line is being typed out character by character with the default coolType options.';
var options = {
    typeSpeed: 10, // Adjusts the speed (in milliseconds) that the characters are typed out.
    inline: true, // If false, line should be inserted as a block rather than inline.
    cursorChar: '&#9608;', // The character to use as the cursor.
    cursorBlinkSpeed: 300, // The speed (in milliseconds) that the cursor should blink.
    delayBeforeType: 1000, // The time to wait (in milliseconds) before typing the text.
    delayAfterType: 3000, // The time to wait (in milliseconds) after typing the text.
    onComplete: false, // A function that will be called when coolType is finished.
    onBeforeType: false, // A function that will be called right before typing begins.
    onAfterType: false, // A function that will be called right after typing finishes.
    expansions: [
        '&nbsp;',
        '&gt;',
        '&lt;',
        '&quot;',
        '&amp;'
    ] // An array containing strings that should be typed as a single character.
};
$('body').coolType(msg, options);

Character Expansions

Sometimes you don't want a sequence of characters to be typed out, such as &gt;. &gt; is an HTML entity for the "greater than" character. If coolType were to type it out character by character then you would see &gt; on the page instead of > like you were probably expecting. By adding &gt; to the expansions array (which it is by default) coolType knows to insert all the characters at the same time as if they were a single character.

To add new expansions simply pass in a string array containing the expansions.

$('body').coolType('Hello&nbsp;world!', {
    expansions: [ '&nbsp;' ]
});

NOTE: This does not work for HTML tags, at least not the way you'd expect.

$('body').coolType('<h1>hello world!</h1>', {
    expansions: [ '<h1>', '</h1>' ]
});

Technically the above code will work but because coolType inserts the opening tag onto the page before the closing tag most browsers will automatically add a closing tag immediately after. Most browsers will then also ignore the closing tag we add because the opening tag was already closed automatically. Essentially you end up with this:

<h1></h1>hello world!</h1>

This is a much more difficult problem to solve than one might think so I don't currently have any plans to support HTML tags in coolType. However, do feel free to submit pull requests if you think you have an idea how to accomplish this.
