Question

I have a large form built with twitter’s bootstrap kit. The fields look like so:

<div class="clearfix">
    <label for="state_id">State</label>
    <div class="input">
        <select id="state_id" name="state">
           <option value="122">Alabama</option><option value="123">Alaska</option><option value="124">Arizona</option> 
        </select>
    </div>
</div><!-- /clearfix -->
<div class="clearfix">
    <label for="city_id">City</label>
    <div class="input">
        <input type="text" id="city_id" name="city" value="" />
    </div>
</div><!-- /clearfix -->

They offer an error class that highlights the field in red like so:

<div class="clearfix error">
    <label for="state_id">State</label>
    <div class="input">
        <select id="state_id" name="state">
             <option value="122">Alabama</option><option value="123">Alaska</option><option value="124">Arizona</option> 
        </select>
    </div>
</div><!-- /clearfix -->

Is there a way to use jquery and validate my form fields and add this class if needed?

My jquery call is simply:

$('#form_submit').click(function(){

    var formValid = true;

    $("div.clearfix").each(function() {
            // 
    });
});

Maybe you can consider use the jquery validation plugin just to make the validation rules. Really is a powerful plugin.

example:

$("input [type='text']").rules("add", { minlength: 2 });

So, when you calls $("form").validate() this function returns all invalid fields.
