Usage

Launchy! is very easy to install and use:

HTML

Wherever you want to have a Launchy! control + window appear in your HTML content, simply wrap your content with a <div> and add the data-launchy attribute.

Example:

<div data-launchy data-launchy-text="Launch window!" data-launchy-title="My modal window">
    <p>This content will appear in the modal window.</p>
</div>

• Required: data-launchy -- Attribute is required but the value can be anything
• Required: data-launchy-text -- This is the text that will be output to the launcher control
• Optional: data-launchy-title -- The text which appears in the heading of the modal window, recommended for greater a11y context ?
• Optional: data-launchy-button -- If you'd rather have button elements instead of the default a elements as launcher and close controls

Custom Close Controls

You can add your own custom close controls to any Launchy! modal window!

1. Add the HTML element you wish to use for the control within your content
2. Apply the data-launchy-close attribute

Example:

<div data-launchy data-launchy-text="Launch window!" data-launchy-title="My modal window">
    <p>This content will appear in the modal window.</p>
    <a href="#" data-launchy-close="?">Ok!</a>
</div>

Clicking on the "Ok!" link will hide the modal window and send focus back to the launcher control!

Custom Refocus Controls

You can add your own custom "refocus" controls to any Launchy! modal window!

1. Add the HTML element you wish to use for the control within your content
2. Apply the data-launchy-refocus attribute
3. Set the value of the data-launchy-refocus attribute to the id of the element you wish to send focus to

Example:

<div data-launchy data-launchy-text="Launch window!" data-launchy-title="My modal window">
    <p>This content will appear in the modal window.</p>
    <a href="#" data-launchy-refocus="post-title">Send me to the article headline!</a>
</div>

<!-- Somewhere else in your page… -->
<h1 id="post-title" tabindex="-1">My perfect sundae…</h1>

Clicking on the "Send me to the article headline!" link will hide the modal window and shift keyboard focus to the <h1 id="post-title"/> element!
