JQuery-Validation - using rules method on selected ID, why does the name attribute have to be present on the element?

Question

I\'m a little confused about the JQuery validation plugin behavior.

If I have the following JQuery:

$(\'#form1\').validate({
    /* other validation          


        

Answer 1

A name attribute is required on the element firstly because that's what jQuery validate uses internally as a key for each field, and secondly because the name attribute is required on input elements to ensure the page validates to the specified DOCTYPE.

Answer 2

If you want to apply the rules using the id then use like this,

$(function () {
  var $field = $("#id_field").attr("name");
  var $params = {debug:false, rules:{}, messages:{}};
  $params['rules'][$field] = {"required": true, "rule": ["params"]};
  $params['messages'][$field] = "error message";

  $("#frm").validate($params);
});
