title: How to pass input text as parameter to javascript onblur event?
body: <p>This is the code for an input text field. What I want is to call the "checkDateFormat" function with the text input as a parameter when the user leaves the field.</p>
  
  <p>Here is the code I've written:</p>
  
  <pre><code>Fecha de prueba: &lt;input type="text" name="date_t" id="date_t" value="22/08/2014" onblur="checkDateFormat(this.date_t.value)"&gt;&lt;br&gt;
  </code></pre>
  
  <p>However I'm sure the function isn't even called.</p>
  
  <p>What am I doing wrong?</p>
