The environment I tested was IE10, which simulated IE8 in the developer tool of IE10, and the test passed. (I have set the security permissions on the browser, so it shouldn't matter)

Fixed 1 minor bug written by this person, added several methods, mainly passed IE8 test (IE8 was not supported before).

This is the end of this article, I hope you enjoy it.
