Add icon to submit button in twitter bootstrap 2

Question

I want to use the twitter bootstrap icons on my form input submit buttons.

The examples on http://twitter.github.com/bootstrap/base-css.html#icons mainly show style

Answer 1

You can add an with the icon somewhere, and bind a JavaScrit action to it, that submits the form. If necessary, the name and value of the original submit button's name+value can be there in a hidden attribute. It's easy with jQuery, please allow me to avoid the pure JavaScript version.

Suppose that this is the original form:

Change it like this:

   ...other fields...
   
       Let me in
   

...and then the magical jQuery:

$("#myFavoriteFormSubmitButton").bind('click', function(event) {
   $("#myFavoriteForm").submit();
});

Or if you want to make sure that the user can always submit the form --that's what I would do in your shoes--, you can leave the normal submit button in the form, and hide it with jQuery .hide(). It ensures that login still works without JavaScript and jQuery according to the normal submit button (there are people using links, w3m and similar browsers), but provides a fancy button with icon if possible.
