Operations like .val() return a string, so If you need to extend a
string you have to use String.prototype:
String.prototype.slug = function(){return this.trim().etc...}
The way you've done it works, but in the same way 'trim' works, i.e.
you have to pass the string to the function:
$.slug($('#form_element').val());
