Hi Yuval,
I was trying to do the same as you passing vars to controller via DIV. The
fact is (as far as I tested), ajax(url, ['name'], 'target') doesn't work
with "_name" of DIV (or <textarea> (or maybe some other tags, to be
tested). The ajax call functions but "request.vars" is empty. You can use
<input> or <select> instead. Assign your value to "_value" of the tag and
give the tag name in ajax. You may set the block hidden by css if the only
function of the block is to pass the var. A piece of example code in "VIEW":
<input id="pass_value" name="some_value"></input>
<div id="ajax_call">bu la bu la</div>
<div id="target"></div>
<script type="text/javascript">
$(document).on("click", "#ajax_call", function(){
jQuery(pass_value).val('value_to_controller');
ajax("{{=URL('ajax_call_function')}}", ['some_value'], 'target');
});
</script>
Hope this helps.
