Screenshot for your reference.

Other browsers tested:
   Nightly build of Safari: Fail
                  Chrome 4: Fail
  Public Released Safari 4: OK
               Firefox 3.x: OK
                    IE 7/8: OK
                  Chrome 3: OK

What steps will reproduce the problem?
1. Load the url
2. Pay attention to the right area of gray showing "数据载入中..." (The Chinese
means "Data loading...")
3. Nightly build of Safari and Chrome 4 cannot load the content of this area
while Chrome 3 can (as well as other browsers)

What is the expected result?
Nightly build of Safari and Chrome 4 show the content of the gray area as same
as Chrome 3 and other browsers.

What happens instead?
Nightly build of Safari and Chrome 4 cannot load the content in this area.

Please provide any additional information below. Attach a screenshot if
possible.
This page adds two event listener to window.onload, and the first one
("cdn_sendData()" ) removes itself in itself.
But this causes Nightly build of Safari and Chrome 4 to remove the second
function("loadifrs()") registered to window.onload event unexpectedly.
Chrome 3 and public released Safari 4 have not this bug.
