You could get the value inside your iterator by looking at:

this.getAttribute('sale_num')

Inside of an invoke iterator, 'this' is set to the current object of affection.

Don't forget to give your generated checkbox an ID or name or something else based on this value you get, so your checkboxes will tell a story to your compare script!

Hello.
I have this HTML code:
<div class="item_content" sale_num="12345">some stuff</div>
<div class="item_content" sale_num="123456">some stuff</div>

I need to insert a checkbox into div "item_content" with value of
"sale_num" attribute.
I'm trying to do it with:
$$('div.item_content').invoke('insert', {bottom: '<input
type="checkbox" class="compare_itm" value="????????" />' });

but i have no idea how to continue.
thanks in advance.
