jQuery Slugify
Update
Please have a look at Madflow's implementation of jQuery Slugify. It's a more mature and active project. In theory, you should be able to drop in and replace the code. Please let us know how it goes.
About this version
A jQuery plugin to create a URL slug as you type a page title (like Django slugify())
Say you have form that looks like this:
<label for="title">Title, e.g. "My Cool Blog Post"</label>
<input type="text" name="title" id="title">
...
<label for="slug">Slug, e.g. "my-cool-blog-post"</label>
<input type="text" name="slug" id="slug">
Use slugify() to automatically fill out the slug field as the user types a title.
$('#slug').slugify('#title');
