jQuery Validation Plugin query -

i have been trying add validation phone field accept 10 14 digits (other better uk phone validation methods welcome).

i using jquery validation plugin.

<form class="form" id="lg.callback.form" action="[[~[[*id]]]]" method="post">     <input type="hidden" name="nospam:blank" value=""/>     <label for="name"> name: <span class="error">[[!+fi.error.name]]</span></label>     <input id="name" type="text" name="name" value="[[!+fi.name]]" required />     <label for="phone"> phone: <span class="error">[[!+fi.error.phone]]</span></label>     <input id="phone" type="text" name="phone" value="[[!+fi.phone]]" class="phone"/>      <input type="submit" value="request call back"/>  </form>  <script>     $("#lg.callback.form").validate(); </script>
