Is there any way to catch a form's `submit` action before HTML5 validation steps in? 

This is [what I have tried](http://jsfiddle.net/Claudius/GFsEE/2/):

**HTML**

```
<form method='post' >
    <fieldset>
        <input type='email' name='foo' required />
        <input type='submit' />
    </fieldset>
</form>

```

**jQuery**

```
$('form').submit(function() {
    $('fieldset').addStyle('error');
    return false;
})

```

But the `submit` is only triggered once the HTML5 validation passes.
