#Solution

    <script type="text/javascript">
    //<![CDATA[
    
        var contactForm = new VarienForm('contactForm', true);
    
        jQuery('#contactForm').submit(function(){
            console.log('submitted');
            jQuery(document).foundation('equalizer', 'reflow');
        });
    
    //]]>
    </script>

Difference here is, you are now listening to the event `submit()` instead of `click()`. Due to this your jquery function will be triggered after validations are carried out by `VarienForm`.

#Why does it so ?

See `VarienForm` declaration in `js/varien/form.js`.

    VarienForm = Class.create();
    VarienForm.prototype = {
        initialize: function(formId, firstFieldFocus){
            this.form       = $(formId);
            if (!this.form) {
                return;
            }
            this.cache      = $A();
            this.currLoader = false;
            this.currDataIndex = false;
            this.validator  = new Validation(this.form);
            this.elementFocus   = this.elementOnFocus.bindAsEventListener(this);
            this.elementBlur    = this.elementOnBlur.bindAsEventListener(this);
            this.childLoader    = this.onChangeChildLoad.bindAsEventListener(this);
            this.highlightClass = 'highlight';
            this.extraChildParams = '';
            this.firstFieldFocus= firstFieldFocus || false;
            this.bindElements();
            if(this.firstFieldFocus){
                try{
                    Form.Element.focus(Form.findFirstElement(this.form))
                }
                catch(e){}
            }
        },
    
        submit : function(url){
            if(this.validator && this.validator.validate()){
                 this.form.submit();
            }
            return false;
        },
        ...
    } 

You can see above that `Validator` is called inside the function `submit`. This means `VarienForm` validation is bind to the event `submit`.

In your case, you are using `click()` event on button, which will be fired before `submit()` event on form. This is why it is not working in your scenario.

In my solution, we are using form submit event and which is loaded after varien form call. Due to this, jquery submit call will be fired only after `VarienFrom` has done.
