jquery , asp.net
<p>I am trying to use jquery to select a checkbox when another checkbox is selected. This wuld have been easy if the ids of the checkboxes are constant but they can change so I have tried to use classes instead, unfortunately asp.net applies the class name on the span element wrapping the checkbox instead of applying on the checkbox directly, so i need to get the checkbox via the inner element of the parent span </p>

<pre><code>&lt;script type="text/javascript"&gt;
     $(document).ready(function() {
     $('#ctl00_ContentPlaceHolder1_Category_ctl00_ProductBusinessLine_chkEL_157').click(function() {

     if (this.checked) {
         var pl = $('#ctl00_ContentPlaceHolder1_Category_ctl00_ProductBusinessLine_chkPL_313')


         pl.attr("checked", true);
     } 


         })
     }); 
&lt;/script&gt; 
</code></pre>

<p>My code, previously working with the checkbox ids, is above, pls help!</p>
