Obfuscated code fails to work in IE8 about javascript-obfuscator HOT 21 CLOSED

thanks, after disable the consoleoutput, it works.

from javascript-obfuscator.

what version you use?

from javascript-obfuscator.

I've used 0.8.0. Should it help to update to 0.8.1?

from javascript-obfuscator.

Only one place where []["filter"]["constructor"]("return this")() still using is following line (looks like i forgot to change this line):
https://github.com/javascript-obfuscator/javascript-obfuscator/blob/master/src/templates/custom-nodes/debug-protection-nodes/debug-protection-function-node/DebugProtectionFunctionTemplate.ts#L13

I will replace this line today on {}.constructor('debugger')()

from javascript-obfuscator.

Thanks! I see that this line is intended to be used with debug protection mode. However, my script has been built without debugProtection flag set to true (actually, without this flag at all, but readme says its default value is false). Is this a desired behavior?

from javascript-obfuscator.

maybe it is line here https://github.com/javascript-obfuscator/javascript-obfuscator/blob/0514793257b306d38b0936ec16031818b5e783c7/src/enums/JSFuck.ts
but i tested code before 0.8.0 release on ie9 in ie8 compatibility mode and it doesnt't throw any errors.

Anyway i change this lines today and i hope it helps for you.

Thanks again! One more issue: disableConsoleOutput option works not as expected:
With value set to true, console.log function is replaced with the following one:

This obviously hangs the page with an infinite loop, and surely this is not an expected behavior (this option is turned on by default!)
This also affects other console methods, such as warn, info and error.

One more issue: disableConsoleOutput option works not as expected

already fixed in 0.8.1. In 0.8.1 infinity loop replaced on just empty functions

That's correct, I was using an outdated dependency, my fault.
I'll close the issue for now, hope your fixes will resolve the initial problem.

Thanks, I will perform heavier autotesting on it next week. For now, I've performed several manual builds and they seem to work in IE8.

@sanex3339 hi,I'm using the webpage to do the obfuscate, the obfuscated code doesn't work in IE8.

from javascript-obfuscator.

Hi, show me your obfuscator options and if possible obfuscated code please.
Does the code without obfuscation work in IE8?

from javascript-obfuscator.

i will look into it

from javascript-obfuscator.

I haven't any runtime errors. How the code should work? Did you have runtime errors on IE8?

If you doesn't have any expected output to the console - set disableConsoleOutput to false. disableConsoleOutput disable console.log, console.error, console.warn and console.info output to the console.

Nice!

So, i will close this issue. If you will find any problems with ie8 - just create new issue.
