Today one of my colleague faced an issue with Thickbox. He was using “rel” tag to group images and show in gallery. Code was working fine but suddenly it stopped working after updating the jQuery library to latest version(1.4). After lot of debugging we found the issue. Below line throws an exception
“unrecognized expression: “.
TB_TempArray = $("a[@rel="+imageGroup+"]").get();
Issue was with “@” selector which was not supported in latest jQuery. We had replaced it and finally got the code working.
TB_TempArray = $("a[rel="+imageGroup+"]").get();
Hope this may help someone
