JS script causes session loss

If you use a modal pop-up window in the page, you will still need to pop up a new window in the modal window if you use it directly in the modal window window.open () or Window.location.href pop-up new window, the new window will not enjoy the page session, resulting in the original session are not accessible, the solution is to use Window.dialogArguments.open () to pop up a new window, window.dialogarguments is a reference to the parent window of the modal window so that the pop-up window can access the session. So when the session loss problem arises, you can not only consider IIS, background code and other reasons, but also should pay attention to the operation of JS and other problems.
