jQuery to prevent multiple submit on a form

/ Published in: jQuery

To prevent multiple submit from sending more than one request,
bind the submit event and store a "disabledOnSubmit" data. Next time the event "submit" will be fire, the following jQuery code will return false. All submit buttons are also disabled (nice user feedback).

Copy this code and paste it in your HTML

$(document).ready(function() {
  $('form').submit(function() {
    if(typeof jQuery.data(this, "disabledOnSubmit") == 'undefined') {
      jQuery.data(this, "disabledOnSubmit", { submited: true });
      $('input[type=submit], input[type=button]', this).each(function() {
        $(this).attr("disabled", "disabled");
      });
      return true;
    }
    else
    {
      return false;
    }
  });
});
