Window.location.href Jump Failed

I hate this problem because it has been a long time, as an incompetent semi-developer, very unfamiliar with the front end, the level is limited to alert debugging

This problem seems to be a silly bug caused by IE, in the Ajax prevailing today, when the return to the Success State (200) is particularly prone to problems, causing the browser cannot jump.

The reason for this is because Window.location.href is disturbed by other code (for example, void (0), return false), which causes the parent frame to not be found.

Solution, there is one:

In

window.location.href = URL;

Add a sentence after

Window.event.returnValue = false;

Window.location.href Jump Failed
