Internet Explorer 11 returns AJAX HTTP Errors usually HTTP Result Code: 500 but it also sent back a HTTP Result Code: 12019 when requesting Model Forms with Webform.

I don't know about other versions of IE.

The Modal Form with the Webform is working perfectly for Safari, Chrome and Firefox.

I switched from Modal forms 7.x-1.2 to Modal forms 7.x-1.x-dev so I could use a patch made for the development version which successfully fixed an AJAX bug on iPad and iPhone.

Unfortunately an Explorer browser problem is one I can't ignore. It's amazing how many people use it.

Anyone have any ideas?

Thanks.

To All,

Forgive me if I'm not using the the correct forum process here. I'm not very forum savvy.
I'm reporting a new find concerning this issue.
It seems that a URL parameter (argument) is the cause of IE11's throwing AJAX errors. Not Modal Forms!

Without the URL Argument, Modal Forms works on IE11 - works:
www.MyWebsite.com/modal_forms/nojs/webform/39

With a parameter (argument) at the end of the URL it causes AJAX to fail:
www.MyWebsite.com/modal_forms/nojs/webform/39?product_name=[A%20String%20of%20Text%20Here]

There seems to be an URL parameter encoding issue with Internet Explorer versions 10 & 11 ( IE10 , IE11 ).

This comment by openthinktech appears to head in the right direction:

gk (google keys): url parameter ie11

These seem to confirm that hypothesis:

Unicode in URL changes for IE11 -

encoding of query string parameters in IE10 -

Does anybody think my conclusion is correct….. or incorrect. Any guidance is appreciated.

If anyone knows where I can "Hook" in PHP to conditionally redirect Internet Explorer to a regular Webform node, it would help.

I'm using the URL parameter to pre-populate a Webform form text area with a string of text related to any product.
If someone can tell me about a work around I would be grateful. I might resort to Javascript.

Thanks!

Hi All,

For anyone it might help, I've solved my problem.

I had an unencoded colon ":" in my parameter string (idiot). Every browser I tried aside from Internet Explorer(s) worked in spite of the unencoded colon. I tried the modal form with its webform on IE6 and it too threw a HTTP Response error - that was a good clue.

Here's a nice little online encoding tool (thank you Eric A. and Kathryn S. Meyer): http://meyerweb.com/eric/tools/dencoder/
