title: how to get the server response.responseText after store load extjs 4
body: <p>I'm having one problem with getting the <code>response.responseText</code> from the server response in extjs 4.</p>
  
  <p>Below is my code to load the store:</p>
  
  <pre class="lang-js prettyprint-override"><code>store.load({
      params: {
          'projectid': this.projectid
      },
      callback: function (records, operation, success, response) {
          console.log(records);
          console.log(response.responseText);
      }
  });
  </code></pre>
  
  <p>Actually, when I made the request with the below function, I properly get the <code>reponse.responseText</code>.</p>
  
  <pre class="lang-js prettyprint-override"><code>Ext.Ajax.request({
      url: 'login/GetLoginCheck.action',
      method: 'GET',
      params: {
          'username': values['username'],
          'password': values['password']
          },
      scope: this,
      success: function(response) {
          Ext.Msg.alert(response.responseText);
          var redirect = response.responseText;
          window.location.href = "" + redirect + ".jsp";
      },
      failure: function(response) {
          Ext.Msg.alert('INVALID USERNAME OR PASSWORD');
      }
  });
  </code></pre>
  
  <p>So please suggest me how can I get the <code>response.responseText</code> from the store.load() having a callback function.</p>
