Safari malignant bug (conflicts between IFRAME and onload and alert)

Test environment:

Windows XP SP3

Safari 4.0.5

Safari 5.0

 

Create an HTML file with the following content:

<IFRAME onload = "alert (1)"> </iframe>

Drag this file into safari and Safari will be "dead "......

 

Cause: if the initial src attribute is null or the IFRAME element of "about: blank", Safari will die if its onload event contains functions such as alert, confirm, and prompt.

 

Solution: Do not leave the src attribute blank, or do not write alert ......
