Hi Jarosław,
I was getting this same error, only in IE an could not resolve it until I found the solution here. Thanks a lot. Although it is weird that IE does not recognize the json identifiers by name whereas FireFox works fine i.e.

cache: isCacheAllowed, height: 5,//works in FF, Opera only

‘cache’: isCacheAllowed, ‘height’: 5,//works in all browsers

John,

That might be true. That’s why I’m also mentioning in the post that it’s possible to use className. Example with className is provided in the post, more details: http://madrobby.github.com/scriptaculous/builder/

Cheers,
Jarek

You suggest fixing a bug by replacing this:

$(this._sPaginationSecId).appendChild(Builder.node(‘span’, { class: ‘disabled’ }, ‘<'));

with this:

$(this._sPaginationSecId).appendChild(Builder.node('span', { 'class': 'disabled' }, '<'));

But, according to my JavaScript book (JavaScript: The Definitive Guide), object literal syntax requires the key to NOT be in quotes. That would mean that the first above is correct and the second is incorrect. Am I missing something?

“my code run three or four function [some of them because not implement in browser or not supported ]”

so when i am trying to run the page or refresh i got same error every time. these is not good that they harsh me everytime by showing a error who really not error.

In my case i had an issue with this bug. After post back my page used to get messed up.. After tracing down i came to know that the culprit was “SmartNavigation”. I disabled it and it worked all fine!!!

Just wasting some time on Stumbleupon and I found your entry. Not typically what I prefer to learn about, but it was absolutely worth my time. Thanks.

You are getting the error because class is a reserved word in Microsoft’s JScript engine http://msdn.microsoft.com/en-us/library/ttyab5c8.aspx. You cannot use reserved words other wise it will throw exceptions like the one you got above.

Iona, you have IE 10? that’s pretty new!

You can rig up the Microsoft Scripting for applications to break into the jscript engine and it will give you the line and even a stack trace. Install the scripting host, enable script debug in explorer and ‘web debugging’ in an office app and the options should appear.

I’m fairly certain there’s a tidbit of doc that covers this…
You’re supposed to use either ‘class’ or className, but not class.

I couldn’t find an explanitory doc about it, but this references it…

Its because IE can’t handle json packets without explicit strings as keys. The mind boggles how that browser reached such status.
