why this ie javascript error?

[dave]

IE keeps popping up an error "expected string identifier" for the
following snippet when a page is loading:
The debugger goes to the line with ,'querystring': bar, but it doesn't
highlight it.

All the variables are declared, and the code runs fine in firefox.

function foo(
{
'url':url
,'onSuccess':dofunction
,'onError':function(req)doerrorfunction
,'parameters':{ 'param1':value, 'param2:'another value',
}
,'querystring': bar
}
);

but when I change the code to:
function foo(
{
'url':url
,'onSuccess':dofunction
,'onError':function(req)doerrorfunction
,'parameters':{ 'param1':value, 'param2':'another value',
'bar':'bar value'
}

}
);

What do you mean?
function(reg) {doerrorfunction();} ?

The original string has no sense in JavaScript.
,'parameters':{ 'param1':value, 'param2:'another value',

You seem already found this error - a quote is missing, must be
'param2':'another value',

the code doesn't quite make sense because it's a generalized snippet of
a piece of code I can't post on a google group.

I realized I mistyped. the code comparisons should be:

function foo(
{
'url':url
,'onSuccess':dofunction
,'onError':function(req)doerrorfunction
,'parameters':{ 'param1':value, 'param2':'another value',
}
,'querystring': bar
}
);

function foo(
{
'url':url
,'onSuccess':dofunction
,'onError':function(req)doerrorfunction
,'parameters':{ 'param1':value, 'param2':'another value',
'bar':'bar value'
}

}
);

Again: this line doesn't have sense syntaxically, no matter what amout
of code is being snipped off. It is like !@# = *&^ - you don't need to
see all code to point on such line ;-)

function(req)doerrorfunction statement is not allowed by language rules
(besides being meaningless) and leads to syntax error.

You already fixed the missing quote - after you fix this line the error
will disappear.

Extra info:

Error 1028 "Expected identifier, string or number"
You used incorrect literal syntax to declare an object literal. The
properties of an object literal must be an identifier, a string, or a
number. An object literal (also called an "object initializer")
consists of a comma-separated list of property:value pairs, all
enclosed within brackets. For example: var point = {x:1.2, y:-3.4};

To correct this error:
Ensure you use the proper literal syntax.
