HtmlElement unindentified error when using ie11 with document mode 8

Hi John and Tomislav,

@John Smith:

Actually, this problem comes with IE browser itself. In IE10 and IE11, it has its own rendering mode that different from the other IE version. When you emulate IE10 and IE11, it doesn't put the right user agent string that we expect to render our control correctly. In additional in IE11, it also has many obsoleted function that we used to rendering our control.

There are many similiar issue that other people facing when emulate IE10 and IE11 (for example: you could see this forum). These changes from IE10 and IE11 also affect our control when you emulate the browser. Many issue also could happen in your project if you emulate your internet explorer version in the future. So to resolve this issue, we really recommend you to change your doctype and rendering mode to HTML5 doctype so it will adapt with IE10 and IE11 doctype standard which is HTML5 doctype.

@Tomislav:

By using try catch statement, I don't think this issue will be resolved. Just like the other issue that the other facing in IE10 and IE11, those IE have its own rendering method that different with other IE version. So it will be more suitable if you're using HTML5 doctype in IE10 and IE11.

Hope this helps.

Regards,
Bernard

Cant you just put that piece of code inside try-catch block?

I'm curious now. Does that mean you are saying that you no longer support IE8 emulation in IE11? Even though 3 weeks ago before those security patches came down from Microsoft it worked fine in IE11?

Why the sudden change?

Hi,

Actually this error happen because when you emulate IE, it only change the document mode to IE8. This might cause problem when our API want to get HTMLElement which different for each browser type and browser doctype. As proof, if you change the user agent string to Internet Explorer 8, the javascript error that you're facing won't be appear. When you're using document mode and user agent string to IE8, Internet Explorer rendering method will changed to XHTML which our control expected as IE8. I think there are no other way to pass this issue except by changing your user agent string to Internet Explorer 8 or by changing its doctype and RenderingMode to HTML5. Hope this helps.

Bernard

Hi Bernard,

So we are using the new hotfixed DLL's for the grid and other controls to render in IE11. For the most part things are running more smoothly, but we are still receiving the HTMLElement javascript errors when using the Meta Tag to emulate IE8. The odd thing is the controls appear to be rendering correctly regardless of this JS error. As I've mentioned before, the IE8 meta tag is still required for style/markup reasons on our older versions as we can't feasibly change every past released version of our application. We are slowly phasing out these older browsers, but are not complete in that task.

Is there anyway you can add feature detection for the HTMLElement object before using it in the IE11Engine you use such that you defend against these JS errors?

Hi Ryan,

Actually, there are no workaround to change user agent string to Internet Explorer 8. We usually suggest our customer to change its doctype to HTML5 and use our control in RenderingMode HTML5. We are doing this because when Using IE11 and IE10, those Internet Explorer only support HTML5 as its primary doctype. Especially when you're using IE11, there are many obsoleted function that we have handle by using RenderingMode HTML5 and HTML5 doctype. Hope this helps.

Bernard

Hi Bernard,

Do you have any other work arounds? We can't force the user-agent string from code (unless I am mistaken?). This does work if we change it in the dev tools in IE but we can't expect our customers to switch this every time they log into our application.

We use document mode emulateIE8 because the columns don't align properly otherwise. When switching the document mode to IE8, the grid now shows up but the columns do not align properly.

This is incredibly urgent as it affects all of our customers on all versions of our application. Please let us know as soon as possible if you have anything we can use.

Regards,

Ryan

Hi Tomislav Mesaric,

I think when you're using XHTML doctype, you should change your RenderingMode to XHTML. Perhaps this issue happen because you only change your document mode to emulate IE8. You have to change your User agent string to Internet Explorer 8 if you are using XHTML doctype. Hope this helps.

Bernard

Hi,

our current application wide setup is that we force document mode 8, because we expose through 4.0 framwork shell, some old 1.1 framework pages.

And ie8 allowed to modes per pages, standards for new pages and quirks for older ones.
