title: Access values from cookies using sencha extjs
body: <p>I am pretty new to <a href="/questions/tagged/sencha" class="post-tag" title="show questions tagged 'sencha'" rel="tag">sencha</a> as well as JavaScript. So can you please help me with how to use Sencha ExtJS and extract information from cookies. I have set the state of a gridpanel in cookies and now I want to extract the value of columnOrder and other information from cookies. </p>
  
  <p>Any code or reference will be really appreciated.</p>
