  <p>My code follows:</p>
  
  <pre><code>var xmlDocument = encodeURI('https://api.dc1.exacttarget.com/integrate.aspx?qf=xml&amp;xml=&lt;?xml version="1.0" ?&gt;&lt;exacttarget&gt;&lt;authorization&gt;&lt;username&gt;EXCATTARGET-USER&lt;/username&gt;&lt;password&gt;EXCATTARGET-PASS&lt;/password&gt;&lt;/authorization&gt;&lt;system&gt;&lt;system_name&gt;subscriber&lt;/system_name&gt;&lt;action&gt;add&lt;/action&gt;&lt;search_type&gt;listid&lt;/search_type&gt;&lt;search_value&gt;17571300&lt;/search_value&gt;&lt;search_value2&gt;&lt;/search_value2&gt;&lt;values&gt;&lt;Email__Address&gt;test21@email.com&lt;/Email__Address&gt;&lt;status&gt;active&lt;/status&gt;&lt;Full__Name&gt;&lt;/Full__Name&gt;&lt;ChannelMemberID&gt;&lt;/ChannelMemberID&gt;&lt;/values&gt;&lt;update&gt;true&lt;/update&gt;&lt;/system&gt;&lt;/exacttarget&gt;');
  
  $('.triggerAjax').click(function() {
