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.optionValue ;
value = jsonOBJ.application.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?

So try what I did. Does it work for you?

Hi
Thanks for the reply . I am geting the responseText value as below

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

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.

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

Because jsonOBJ would have the value `undefined' if the evaluation failed,
if that.

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

Thomas 'PointedEars' Lahn said the following on 9/29/2007 9:16 AM:

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.
