JSON object not parsing in firefox

[saril.ks]

Hi
The JSON object I am using is as below . this object is returned after
an AJAX call

{"application" :[
{optionValue:"101", optionDisplay: "estmt"},
{optionValue:"11", optionDisplay: "Arif"},
{optionValue:"12", optionDisplay: "JC"}
]}
In the JS i am using the below code

data = ajaxRequest.responseText ;
var jsonOBJ = eval('(' + data + ')');
len = jsonOBJ.application.length ;
key = jsonOBJ.application[i].optionValue ;
value = jsonOBJ.application[i].optionDisplay ;
Internet Explorer is able to process the above code , but while trying
from Firefox , I am getting the below error message

jsonOBJ has no properties
[Break on this error] len = jsonOBJ.application.length ;

Please help

Thanks

I couldn't break Firefox with this:

var data = '{"application" :[\n\r{optionValue:"101", optionDisplay:
"estmt"},\n\r {optionValue:"11", optionDisplay: "Arif"},\n\r
{optionValue:"12", optionDisplay: "JC"}\n\r ]}';
var jsonOBJ = eval('(' + data + ')');
len = jsonOBJ.application.length;
alert(len);

Are you sure about the responseText value?

Evaluating that results in a compile error:

| Error: invalid label

Tested in Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7)
Gecko/20070914 Firefox/2.0.0.7 (with Firebug 1.05).

In contrast,

[ {optionValue:"101", optionDisplay: "estmt"}, {optionValue:"11",
optionDisplay: "Arif"},{optionValue:"12", optionDisplay: "JC"}]

evaluates fine.

{application: [ {optionValue:"102", optionDisplay: "estmt"},
{optionValue:"11", optionDisplay: "Arif"},{optionValue:"12", optionDisplay:
"JC"}]}

is OK, too.

I presume the reason why it breaks with `"application":' is that the outer
`{...}' is regarded as delimiters of a block statement by eval(), and not as
delimiters of the Object literal notation. Hence eval()uating the variant
with `application:' yields only the Array object, which has no `application'
property. Both `"application":' and `application:' are merely regarded as
labels in a block statement there, with the former being invalid.

I don't think you have relized yet that you are shooting yourself in the
foot. As I have pointed out, because of the block statement - object
literal and property name - label ambiguities, `jsonOBJ.application.length'
may or may not work with unquoted `application', depending on the script
engine that compiles this. You should use JSON.parse() instead.

I did not use JSON.parse() as it was throwing exceptions in firefox .
But when i unquoted the 'application' , i am able to parse the
jsonOBJ . Do you have any snippets to handle JSON.parse()
exception ?

Thanks

try
{
ajaxRequest.responseText.parseJSON()
}
catch (e)

Error prone on the web.

^^^^^^^^^^^^^^^^^^^

Because of NN/IE 4.x?

It adds no more error-proneness here because -- surprise, surprise! -- the
current JSON parser implementation in J(ava)Script already uses `throw' to
throw the aforementioned exception:

http://www.json.org/js.html

The incompatibility with try...catch in ECMAScript < 3 implementations can
be worked around proprietarily with window.onerror and eval(), though.

Are you saying that you believe that NN4.x and IE4.x are the only
browsers potentially being used that don't support try/catch? try/catch
is error prone on the web.

It adds no more error-proneness here because -- surprise, surprise! -- the
current JSON parser implementation in J(ava)Script already uses `throw' to
throw the aforementioned exception:

That doesn't make try/catch/throw any less error prone.
