  <blockquote>
    <p>jquery.repeater.js:688 Uncaught TypeError: Cannot read property 'set'
    of undefined</p>
  </blockquote>
  
  <p><strong>Form code:</strong></p>
  
  <pre><code>&lt;form action="" class="repeater" enctype="multipart/form-data"&gt;
    &lt;div data-repeater-list="users"&gt;
      &lt;div data-repeater-item&gt;
        &lt;input type="text" name="name"/&gt;
        &lt;input type="email" name="email"/&gt;
        &lt;select name="sex"&gt;
          &lt;option value="0" selected&gt;Male&lt;/option&gt;
          &lt;option value="1"&gt;Female&lt;/option&gt;
        &lt;/select&gt;
        &lt;input type="date" name="birthday"/&gt;
        &lt;input data-repeater-delete type="button" value="Delete"/&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;input id="add" data-repeater-create type="button" value="Add User"/&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p><strong>Javascript code:</strong></p>
  
  <pre><code>$(document).ready(function () {
      'use strict';
      $('.repeater').repeater({
          defaultValues: {
              'name': 'User',
              'email': 'user@gmail.com',
              'sex': '0',
              'birthday': "1990-09-10"
          },
          show: function () {
              $(this).slideDown();
          },
          hide: function (deleteElement) {
              if(confirm('Are you sure you want to delete this element?')) {
                  $(this).slideUp(deleteElement);
              }
          },
          ready: function (setIndexes) {
  
          }
      });
      $('#add').on('click', function(e){
        var users = $('.repeater').repeaterVal();
        console.log(users);
      });
  });
  </code></pre>
  
  <p>When I don't set default value then I can't get all fields values.</p>
