Question

I have a page that can either be opened via Fancybox or viewed without fancybox. Can i somehow in javascript check if this page was opened using fancybox or not?

Answer 1

Since this is an external page, you would most likely open it with fancybox using "type":"iframe"

You could simply put this code inside that page:

if(parent.jQuery().fancybox) {
 alert("I was opened inside fancybox");
}
