JS script in IE browser "developer mode" normal, but the normal use of the function does not work

Problem Description : Use of Third-party plug-ins online to generate a document function, IE use this function, the function can not be used, always execute half do not execute, no error in the background, but open the browser "developer mode" to see if there is JS error, in the developer mode not only no error, Features can be used normally, but can not be used if the developer mode is turned off.

Problem Solving: This problem is really annoying, other browsers are no problem, only IE browser problems, when you want to use tool debugging, the problem is not. Only one line of the trial code, see where the bottom is not executed, you can use the alert method, but this is always blocking the program may affect the test results, you can use $ ("body"). Prepend ("a") to change the content of the page to mark the location of the program execution.
Finally try to come out because of console, IE for console support is not good, but if you use the developer mode, then the debugging tools so that IE recognized the console, so try not to keep the test code console in the code. [Log] [INFO] and so on.
