jquery form validation for any select value

Question

I am using jQuery validation plugin, it works fine for all fields but, when I use it for select it doesn't work

HTML

<form>
    <select id="name" name="name">
        <option>Select</option>
        <option value='select'>Select</option>
        <option value='abc'>ABC</option>
        <option value='xyz'>XYZ</option>    
    </select>
    <input type='submit' value='Submit' />
</form>

SCRIPT

var f=$("form").validate({
    rules: {
        name:{
            required:
                 function(element) {
                     st=($(element).val() == '') || ($(element).val() == 'select');
                     return st;
                }
        }
    },
    messages: {
        name: {required: "Please select name"}
});

Also, I want to stop submition after validation, no matter whether the form is valid or not.

Note I don't want to use $.validator.addMethod.

I've already searched

You're right :) Can you not just use return false to stop submission? — dsgriffin, May 17 '13 at 07:41

I'm going to say it's a plugin that's slightly overcomplicating an simple error check! Then again, I found the same thing you're attempting to do on the Developer's Github Demo page.

Fiddle: http://jsfiddle.net/hAWR3/14/

<script>
    $("#formsubmission").submit(function(event){ 

        /** Cache Result **/
        var tmp = $('#selectname').val();
        console.log( "Selected Name: " + tmp );

        if ( tmp == 'select' || tmp == 'Select' ) {

            /** Prevent the submission **/
            event.preventDefault();
            console.log( 'Unvalidated!' ); 

        } else {

            /** Submit as normal!! **/
            console.log( 'Validated!' );   
        }

    });
</script>

<form method="post" id="formsubmission">
    <select id="selectname" name="name">
        <option>Select</option>
        <option value='select'>Select</option>
        <option value='abc'>ABC</option>
        <option value='xyz'>XYZ</option>    
    </select>
    <input type='submit' value='Submit' />
</form>

Note: if there's no value within the like in your html example, it take the encased value inside the <option></option>'s!
