jQuery - on key up go to next input field
<p>I'm currently busy with 13 input fields that's results get merged into a variable, I have to split it into 13 for I need to add a block effect such as you will find on many forms in the real world. the limit to each block is one, I need to find away so that when you insert a digit, it goes to the next field until all fields have been filled then a validation function will fire off.</p>

<p>Heres the html:</p>

<pre><code>&lt;div id="error"&gt;&lt;/div&gt;

&lt;form id="idCheck"&gt;
&lt;input class="id" id="idnumber1" maxlength="1" /&gt;
&lt;input class="id" id="idnumber2" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber3" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber4" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber5" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber6" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber7" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber8" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber9" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber10" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber11" maxlength="1"  /&gt;
&lt;input class="id" id="idnumber12"  maxlength="1" /&gt;
&lt;input class="id" id="idnumber13" maxlength="1"  /&gt;&lt;span id="status"&gt;&lt;/span&gt;
&lt;p&gt; &lt;input type="submit" id="check" value="Check" /&gt; &lt;/p&gt;
 &lt;/form&gt;

&lt;div id="result"&gt; &lt;/div&gt;
</code></pre>

<p>and heres the javascript:</p>

<pre><code>function Validate() {
   jQuery('#error p').remove();
   var error = jQuery('#error');
  var p1 = jQuery('#idnumber1').val();
  var p2 = jQuery('#idnumber2').val();
  var p3 = jQuery('#idnumber3').val();
  var p4 = jQuery('#idnumber4').val();
  var p5 = jQuery('#idnumber5').val();
  var p6 = jQuery('#idnumber6').val();
  var p7 = jQuery('#idnumber7').val();
  var p8 = jQuery('#idnumber8').val();
  var p9 = jQuery('#idnumber9').val();
  var p10 = jQuery('#idnumber10').val();
  var p11 = jQuery('#idnumber11').val();
  var p12 = jQuery('#idnumber12').val();
  var p13 = jQuery('#idnumber13').val();


  var idNumber = p1 + p2 + p3 + p4 + p5 + p6 +p7 + p8 + p9 + p10 + p11 + p12 + p13;
  };
</code></pre>

<p>any help greatly appreciated.</p>
