Hi,
You don't want #invoke, you want #each:
$$('div.item_content').each(function(div) {
div.insert({
bottom: '<input type="checkbox" class="compare_itm"
onclick="Itm.Click(\''+
div.readAttribute('sale_num') +'\')" />'
});
});
http://api.prototypejs.org/language/enumerable/prototype/each/
Also note I've used #readAttribute (Prototype) rather than
getAttribute (DOM), as it handles some issues for you:
http://api.prototypejs.org/dom/element/readattribute/
Off-topic: That HTML is invalid, because you're defining an attribute
(`sale_num`) that doesn't exist in the standard. It works, it's just
invalid. As of HTML5, there's a valid way to have custom attributes:
Use a "data-" prefix. So `data-sale_num` would be a valid attribute
name. FWIW.
HTH,
