I have a bunch of different forms that have common fields. I have a long validation script where i want to extract the common fields so if I make a change to the message I don't have to repeat it. Is there something simmilar to php's include where I can place all of the js that overlaps and just include it into the script?

Here is the validation script:
Code:
<script type="text/javascript">
    $(document).ready(function(){

        $('#contact-form').validate({
          rules: {

            'audience[]': {required: true},
            
            task_name: {
              minlength: 2,
              required: true
            },

            request_desc: {
              minlength: 2,
              required: true
            },

            goal: {
              minlength: 2,
              required: true
            },

            support_location: {
              minlength: 2,
              required: true
            },

            requester_name: {
              minlength: 2,
              required: true
            },

            requester_phone: {
              minlength: 7,
              required: true
            },

              required: true,
              email: true
            },
