IE detection cc_on causes errors on all IE versions that loads javascript with sourcemaps #22

Hi,

This single pease of code: eval("/_@ccon 1;@/") turns on conditional compiling.

When it is turned on, sourseMapUrl's are executed as code instead of comments and causes runtime errors in IE: //@ sourceMappingURL=ClipModel.js.map

removing that peace of code seems to fix the errors, and doesn't seem to break anything, but I'm not sure. I guess there is a better way to detect IE.

use four slashes for mapping code: ////@ sourceURL=ClipModel.js.map

Hi,

Thanks for that, i've also found some similar workarounds, but I think the problem itself should be fixed.

Also, most of the time the sourcemaps are generated by 3rd party tools (like the TypeScript compiler in my case), so you cannot (easily) change the way they are generated.

I agree with you, This problem is known for a long time.
