[jQuery] JSON2007 and each() ?

[Nick Cooley]

Hello everyone -- 

Having a bit of difficulty using jQuery 1.2.6 with json2007.js. (using RSH)

Here's the code

$('h3').each(function(index){
        $(this).attr("id",'button' + (index+1));

})      

Has anyone ever seen this error (via firebug) while trying to run similar
code: 

'String contains an invalid character" code: "5'

As far as I can tell, the "attr" function is trying to process
'toJSONString' as property of the 'h3' element (line 174 of jquery-1.2.6).
When it does so, toJSONString, being a function throws the error... 

Any suggestions for resolution would be appreciated... 

Thanks!

Nick
