IE8 error: Object doesn't support this property or method

[sergiocormio]

jquery.inputmask.bundle.js Version: 3.2.8-17 Line: 852 Char: 21

I think the problem is because IE8 doesn't support getPrototypeOf method [(http://stackoverflow.com/questions/10919915/ie8-getprototypeof-method)]

I'm still getting an error in IE8 (9 and above works fine) from the lines changed in the linked commit.

Callstack is maskScope->mask->patchValueProperty

Errors on the line var valueProperty = Object.getPrototypeOf ? Object.getOwnPropertyDescriptor(Object.getPrototypeOf(npt), "value") : void 0;

Error thrown is Object expected

We have core-js installed (shims es5 and some es6), so the check returns true.

It works fine in 3.2.7 though, just 3.3.0 that throws

@SimenB ,

Can you retry with the version from github?

[RobinHerbots]

@SimenB ,

Sorry, I didn't read your comment thoroughly. Which of the 2 is failing exactly? getOwnPropertyDescriptor or getPrototypeOf. Is it related to the shim?

[SimenB]

I can check later. I think it's related to the shim, as you check if the function exists, and it does, but it doesn't work properly

[SimenB]

getOwnPropertyDescriptor is the problem

[SimenB]

You can't use getters and setters in IE8. You should check if it works, not if the methods to use them exists. See my PR to webpack for sample: webpack/webpack#2087

@SimenB ,

Hmm, without corejs the valuepatching passes without problem, although it also calls the getOwnPropertyDescriptor fn. See latest version on github.

[SimenB]

I'll try HEAD now

[SimenB]

Now it fails on var valueProperty = Object.getPrototypeOf ? Object.getOwnPropertyDescriptor(Object.getPrototypeOf(npt), "value") : undefined;, so same line, I suppose.

Are you able to run it in IE8 if you include core-js/es5 first? IE9 is not a problem

[RobinHerbots]

@SimenB ,

No without core-js, it runs and patches the value

I guess the getPrototypeOf fn gives different result
