title: jquery select and use part of class name
body: <p>I have a lot of classes who starts with <code>edit_</code>. I've styled them with <code>[class^="edit_"]</code>. Now, each class have a different number like <code>edit_20</code> <code>edit_80</code> <code>edit_150</code>. How can i strip the first part of the class name (<code>edit_</code>) so that if passing it to a variable, it will only contain the number? </p>
