this page mainly gets the parameter after the question mark in the URL of this page, and then uses this parameter to modify the Object tag of flash. The specific action is as follows:

var objectHtml = "<object ...>...<param id="fla_var1" name="FlashVars" value=""+ val +"" /></object>"
$("-sharpflashDiv").html("").append(objectHtml);
//

now let"s talk about bug: turning off ie, opening it again, opening the bug web page, testing, and finding that the parameters in flash have not changed, that is to say, the FlashVars has not changed, or the entire Object tag has not changed.
When there is a problem, the habit is to press f12 to see what the problem is, but now press f12, do nothing or close the developer window, refresh the page, and flash switches successfully. That means bug fixed it. But turn off ie and turn it back on, and bug appears again.

tried solution: clear all ie data, bug still

call for help. Why is ie so abnormal? by the way, both ie8 and ie9 have this problem. Other versions are unknown
