Cannot get basic mapbox example to run in IE

[davidcolley]

I've written a script that uses GL-js and cannot get it to work on Internet Explorer but does on Chrome.
As an experiment, I then tried to get just the Mapbox basic example to work on IE and that fails as well :

https://www.mapbox.com/mapbox-gl-js/example/check-for-support/

It works from their own webpage but not when I copy the example code into an html file and load it. It does work on Chrome though as does my script.

Any ideas why it won;t run on IE?
or what needs changing in the example script to get it working?

many thanks

Thanks for getting in touch with us @davidcolley. Could you please tell us

• what version of IE you are using
• what version of Windows you are using
• what kind of graphics card your machine has
• what the "basic example" page looks like when it is "not working"
• the output of this page in the browser that isn't working http://www.doesmybrowsersupportwebgl.com/

Hi there,

I’m using IE11 on Win7 64bit with an NVIDIA Quadro 2000M and the basic page is just blank white and does not allow any user interaction, even right click.

Not sure if it helps but when I run my .NET script that is using the standard System.Windows.Forms.Webrowser (i.e. IE) through a debugger is fails on the line where the .js script is referenced.

Thanks,

[davidcolley]

Hi.

PC

Here i had the same issue. I upgraded my graphics card in my office-PC and now it works. I had a Nvidia GT 210, replaced it with a Nvidia GT 720.

Windows-Phone

I tried it out on my Windows-Phone with IE 11 but it does not work there :(

This likely was fixed by #1606. Please try again on master and I'll reopen if the issue persists.

[kachkaev]

Looks like the problem is there again, at least in IE11 on Win7

Line: 206
Error: 'Uint8ClampedArray' is undefined

Can't see any maps on
https://www.mapbox.com/maps/
https://www.mapbox.com/mapbox-gl-js/example/check-for-support/

The second page does not alert Your browser does not support Mapbox GL.

[mourner]

@kachkaev run update on your Windows 7. See #2444 (comment) for more.

[kachkaev]

Thanks for your reply @mourner! Makes sense.

I'm afraid I won't be able to update IE as it is on a company-managed PC. Our client is likely to have the same env, so I'll probably have to give up gl-enabled maps in this project. Very exited about your stuff after a week of exploration though!

Is Uint8ClampedArray issue something that requires a lot of effort to fix? Or maybe just a couple of lines of codes can do the trick? I can help you with testing in the second case but understand that you might be not willing to your time on it.

[jfirebaugh]

Our previous investigation suggested that there would be additional compatibility issues beyond Uint8ClampedArray. Please encourage your IT department to upgrade IE -- these are important security updates we're talking about.

[kachkaev]

You're right @jfirebaugh, I'll see what I can do. Would it be possible to at least get mapboxgl.supported() working properly in that version of IE? Requested here: #2504. According to a couple of issues I discovered in your repo, it seems that some quite a few potential users can have the same unpatched version of IE. Would be good to be sure that at least a please update message can be shown reliably in any environment.
