Answer 1

Pass them in the query string:

var ad_lng = encodeURIComponent( document.getElementById("longclicked").value );
var ad_subtitle = encodeURIComponent( document.getElementById("ad_subtitle").value );
var ad_lat = encodeURIComponent( document.getElementById("latclicked").value );

$('#iframeHolder').html('<iframe id="iframe" src="<?php echo base_url(); ?>index.php/admin/frame_stimulator?ad_lat='+ad_lat+'&ad_lng='+ad_lng+'&ad_subtitle='+ad_subtitle+'" width="700" height="550" scrolling="no"  frameborder="0"></iframe>');

In codeigniter code you would retrieve them:

$lat = $this->input->get("ad_lat");
$lng = $this->input->get("ad_lng");
$subtitle = $this->input->get("ad_subtitle");

You can invoke a javascript function in an iframe from the parent/container page. So if you script a function in the iframe page that takes data as a parameter, then you can invoke it from the main page that contains iframe.
