What is wrong with my JSON string???

[pbd22]

Hi.

I can't seem to get any values from the below string.
I have tried myJSONObject.sl ides[0], myJSONObject.sl ides['1'],
myJSONObject.sl ides[0].1, etc.
I can't get it to work. Is it because the NAMES are numbers? Can you
get this to work?

Thanks.

Did you try myJSONObject.sl ides[0]['2']?

Re: What is wrong with my JSON string???

yes, thanks.

I get slides.0 is null or not an object.

should I be using eval?

when I try

var x = xmlhttp.respons eText;
var myJSONObject = eval("(" + x + ")");

I get "(" expected.

When I try

var x = xmlhttp.respons eText;
var myJSONObject = eval(x);

I get ";" expected;

I am lost. Why I am I getting these errors?
try/catch isn't really helping. Would somebody
mind throwing my string in their compiler to see
if you get different results?

thanks.

That semicolon at the end of your "JSON" string is erroneous.

I tried it this way (NOT using JSON, just plain javascript)

function setVars(){
thisVal = {'slides': [{'2': 's002.jpg', '3': 's003.jpg', '4':
's004.jpg', '5':'s005.jpg', '6': 's006.jpg', '7': 's007.jpg', '48':
's048.jpg', '17':'s017.jpg' , '27': 's027.jpg', '37': 's037.jpg', '15':
's015.jpg','25' : 's025.jpg', '35': 's035.jpg', '13': 's013.jpg',
'23':'s023.jpg' , '33': 's033.jpg', '11': 's011.jpg', '21':
's021.jpg','31' : 's031.jpg', '41': 's041.jpg', '47': 's047.jpg',
'57':'s057.jpg' , '19': 's019.jpg', '29': 's029.jpg', '39':
's039.jpg','46' : 's046.jpg', '56': 's056.jpg', '49': 's049.jpg',
'51':'s051.jpg' , '42': 's042.jpg', '52': 's052.jpg', '45':
's045.jpg','55' : 's055.jpg', '16': 's016.jpg', '26': 's026.jpg',
'36':'s036.jpg' , '14': 's014.jpg', '24': 's024.jpg', '34':
's034.jpg','12' : 's012.jpg', '22': 's022.jpg', '32': 's032.jpg',
'10':'s010.jpg' , '20': 's020.jpg', '30': 's030.jpg', '40':
's040.jpg','50' : 's050.jpg', '44': 's044.jpg', '54': 's054.jpg',
'18':'s018.jpg' , '28': 's028.jpg', '38': 's038.jpg', '8': 's008.jpg',
'9':'s009.jpg', '43': 's043.jpg', '53': 's053.jpg', '1':
's001.jpg'}]};
}
function getVars(){
alert(thisVal.s lides[0]['2']);
}

and it worked...
What was your problem?

Henry was right, the semicoln shouldn't have been there.

Thanks again.

JSLint can find these sorts of problems in JSON text.
