Try this:
for (var i = 0; i < document.imageForm.elements.length; i++){
if(document.imageForm.elements[i].type == 'checkbox'){
      document.imageForm.elements[i].checked = true;
}
}
> I am producing a form using PHP on the back end and Javascript on the
> front end.  The resulting script will come to the browser as follows:
>
> [Code]
> <script>
> <!--
>   function selectAll() {
>    moveElement = eval("document.imageForm.move" + "[]");
>    alert(moveElement);
>    if (document.imageForm.select_all[0].checked) {
>     for (i = 0; i < document.imageForm.move.length; i++) {
>      document.imageForm.move[i].checked = true;
>     }
>   }
>  }
>
>  function deSelectAll() {
>   if (!document.imageForm.select_all[0].checked ||
> document.imageForm.deselect_all[0].checked) {
>    for (i = 0; i < document.imageForm.move.length; i++) {
>     document.imageForm.move[i].checked = false;
>    }
>   }
>  }
> //-->
> </script>
> [/Code]
>
> This will work with a checkbox group that has to have this naming
> convention for PHP:
>
> [Code]
> <input type=checkbox name=move[] value="myImage.gif"> - Move?
> [/Code]
>
> I will also have a checkbox that will "select all" and "de-select all":
>
> [Code]
> <input type=checkbox name=select_all value=1 onChange="selectAll()"> -
> Select All
> <input type=checkbox name=deselect_all value=1 onChange="deSelectAll()">
> - De-select All
> [/Code]
>
> I am not familiar at how Javascript can work with non-standard naming
> conventions for event actions, can someone tell me what I'm doing
> wrong?  This fails at least in Mozilla 1.6
>
> Thanx
