Code
function overlay_exit() { // Check that we are in an overlay child page. Note that this should never // return TRUE on a cached page view, since the child mode is not set until // overlay_init() is called. if (overlay_get_mode() == 'child') { // Load any markup that was stored earlier in the page request, via calls // to overlay_store_rendered_content(). If none was stored, this is not a // page request where we expect any changes to the overlay supplemental // regions to have occurred, so we do not need to proceed any further. $original_markup = overlay_get_rendered_content(); if (!empty($original_markup)) { // Compare the original markup to the current markup that we get from // rendering each overlay supplemental region now. If they don't match, // something must have changed, so we request a refresh of that region // within the parent window on the next page request. foreach (overlay_supplemental_regions() as $region) { if (!isset($original_markup[$region]) || $original_markup[$region] != overlay_render_region($region)) { overlay_request_refresh($region); } } } } }
