title: How to get dynamic values from html page with LoadRunner?
body: <p>I am using <strong>web_reg_save_param</strong> to get dynamic values, such as <code>&lt;input type="hidden" name="lt" value="foo" /&gt;</code> then I can use it like :</p>
  
  <pre><code>web_reg_save_param("HiddenValue1", 
          "LB/IC=&lt;input type=\"hidden\" name=\"lt\" value=\"", 
          "RB/IC=\" /&gt;", 
          "Ord=1", 
          "Search=body", 
          LAST);
  </code></pre>
  
  <hr>
  
  <p>However, if the <code>&lt;input&gt;</code> of page is like this way:<br /><br /><code>&lt;input type="hidden" name="lt" readonly /&gt;</code><br /><br />the value is set dynamically by ajax script. How can I get the value? There is no "value" property for this <code>&lt;input&gt;</code>.</p>
