title: If element exist then check?
body: <p>The code does work below when the access to the webpage, it automatically hide <code>#OrderDeliveryAddress</code> div. But I am wondering is this correct way doing it?</p>
  
  <p>Is there a way to check if <code>.selectAddressList</code> div/class exist first and then check the value?</p>
  
  <pre><code>$(document).ready(function() {
      if ($(".selectAddressList").val() == "selectAddressBook") {
           $("#OrderDeliveryAddress").hide();
      }
  });
  </code></pre>
