My page got 4 external javascript file which is in php extension. When i load it inside iframe, they work perfectly in Opera and FF but they just don't load in MSIE and Safari. The weird thing is when I load the page directly ( not in iframe ) , it can load in all browsers. Even weird, it works for all browser even in <iframe> in http://localhost when i was testing it. So i did some testing..i typed this in one of the external javascript. alert('testing..'); It alerted 'testing..' in FF and Opera but not MSIE and Safari. So i think the external javascript don't load inside iframe when i was using MSIE and Safari. What can be the problem? I can reward you for this if you solve this problem for me =x Thank you.
