Fire Code on Form Submission

form_submit.js

<script type="text/javascript">
//runs on form submission
function yourSubmitFunction(e, $) {
  e.preventDefault();
  try {
    //ADD CUSTOM CODE HERE
  }
  catch(err) {
    //code to handle errors. console.log is just an example
    console.log(err);
  } 
  finally {
    // This submits the form. If your code is asynchronous, add to callback instead
    gaForm(e);
    lp.jQuery('.lp-pom-form form').submit();
  }
}

//ga form submission event
function gaForm(event) {
  var $form, $formContainer, params;
  event.preventDefault();
  event.stopPropagation();
  $formContainer = lp.jQuery(event.currentTarget).closest('.lp-pom-form');
  $form = $formContainer.children('form');
  if ($form.valid()) {
    if(typeof eventTracker !== 'undefined'){
    if (!eventTracker._isGaLoaded()) {
      return $form.submit();
    }
    params = lp.jQuery.extend({
      category: 'Form',
      action: 'Submit',
      label: "#" + ($formContainer.attr('id'))
    }, $formContainer.data('ubGAParams'));
    eventTracker._logEvent(params);
    return ga('send', 'event', params.category, params.action, params.label, {
      hitCallback: function() {
        return $form.submit();
      }
    });
    }else{
    return $form.submit();
    }
  }
}; 

//waits until window load to initialize
lp.jQuery(window).load(function(){
  lp.jQuery(function($) {
    $('.lp-pom-form .lp-pom-button').unbind('click tap touchstart').bind('click.formSubmit tap.formSubmit touchstart.formSubmit', function(e) {
      if ( $('.lp-pom-form form').valid() ) yourSubmitFunction(e, $);
    });
    $('form').unbind('keypress').bind('keypress.formSubmit', function(e) {
      if(e.which === 13 && e.target.nodeName.toLowerCase() !== 'textarea' && $('.lp-pom-form form').valid() )
      yourSubmitFunction(e, $);
    });
  });
});
</script>

Mind if I submit some cleaned up and commented code?

I think line 14 (https://gist.github.com/noahub/cab64fcf0b05ead054be1ecc01cf6fe9#file-form_submit-js-L14) is unnecessary, since in the gaForm function we do $form.submit().

thanks @wgroth2!!!
