title: Keyword validation in Google Plus textbox
body: <p>I am working with jQuery validation. I want to validate a Google Plus textbox. I want that if the user has not specifically entered <code>google.com</code>  with his entered link then the error message should be displayed.</p>
  
  <p>I tried with following code but it's not working. How can I do this?</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;input type="text" class="form-control" placeholder="Enter google plus Profile Link" name="google_link" id="google_link"&gt;
  </code></pre>
  
  <pre class="lang-js prettyprint-override"><code>(function($, W, D) {
    var JQUERY4U = {};
    JQUERY4U.UTIL = {
      setupFormValidation: function() {
        //form validation rules
        $("#myForm").validate({
          rules: {
            google_link: {
              required: true,
              url: true
            },
          },
          messages: {
          google_link: "Please Enter valid link",
        });
      }
    }
  </code></pre>
