title: Combing multiple .removeAttr() statements
body: <p>I have multiple <code>removeAttr()</code> is there a way I can combine them?</p>
  
  <p><strong>What I have:</strong> (this works)</p>
  
  <pre><code>checkboxes.removeAttr("checked",'checked');
  checkboxes.removeAttr("indeterminate", false);
  checkboxes.removeAttr("role", 'checkbox');
  checkboxes.removeAttr("aria-checked", false);
  </code></pre>
  
  <p><strong>What I have tried:</strong> (this doesn't work)</p>
  
  <pre><code>checkboxes.removeAttr({
      checked: 'checked',
      indeterminate: false,
      role: 'checkbox',
      'aria-checked': false
  });
  </code></pre>
  
  <p>When I try this I get the following console error. So either my syntax is wrong or this just doesn't work. </p>
  
  <pre><code>Uncaught TypeError: Object #&lt;Object&gt; has no method 'toLowerCase'  jquery.min.js:2
  </code></pre>
  
  <p>Any help is appreciated. Thanks.</p>
