tweak 'select all' js function

Hi,

I have a select all js function that works nicely but could use a little tweaking. I recently created a new form that includes hidden checkboxes using CSS that are made visible during a menu select which updates the display attribute from hidden to block. With this new method of storing all required fields on a single jsp the select all function is not working as I'd like it to. When selected, all the form fields hidden and none hidden are selected. So now it is necessary to validate the display attribute before the checkbox is selecting

Here are the details;

Expand|Select|Wrap|Line Numbers

 
function checkall(formname,checkname,state){

   var checkboxes=eval("document.forms."+formname+"."+checkname)

   for (cb=0;cb<checkboxes.length;cb++)

   checkboxes[cb].checked=state

}

Expand|Select|Wrap|Line Numbers

 <html>
 
..... snip ....
 
<div id="menu1" class=hide>

 <div id="main">

  <input type="checkbox"  name="Topic" value="addtopic20"/>

  add Topic 20

 </div>

</div>
 
<div id="main">        /* always visable*/

 <div>

  <input type="checkbox" name="Topic" value="maintopic1" />

  main topic 1 

 </div>    

 <div>

  <input type="checkbox" name="Topic" value="maintopic2" />

  main topic 2 

 </div>    

</div>
 
<a  href="javascript:checkall('queryForm','Topic',true)">Select all</a>  / </font>
 
</html>

Thanks for the suggestions.

Since the checkboxes are within divs which are within divs whose class name is set to hide or whatever, check the parentNode's parentNode's className is equal to "hide".

PS. an ID must be unique. You can't have two elements with the id "main".
