How to use

String.Slugify extends the native String object, so it works on any ordinary string.

"slugify  ME    n%ø#w".slugify()

Returns "slugify-me-now"

Real World Usage Example

This example shows how you can use slugify on two text inputs to create valid slugs from an ordinary title field.

The title field <input id="title">, and the slug <input id="alias">.

We're listening to the change event on the slug input, and the keyup and keydown events additionally on the <input id="title"> element; This is to make the <input id="alias"> input update as you type the title and be slugified in the process:

var aliasvalidator = function(){
    this.value = this.value.slugify();
};
var titlevalidator = function(){
    if(!$('alias').defaultValue) $('alias').value = this.value.slugify();
};

$('title').addEvents({'keyup': titlevalidator, 'keydown': titlevalidator, 'change': titlevalidator});
$('alias').addEvents({'change': aliasvalidator});
