Json eval function in javascript

Question

var jsonCallbackCode1 = eval("employees = { 'accounting' : [ { 'firstName' : 'Jo''hn', 'lastName'  : 'Doe','age': 23 }]}");
alert(employees.accounting[0].firstName);

I got the following exception

Microsoft JScript compilation error: Expected '}'

help me?

I think the problem rely on 'Jo''hn' see the double ' that break the string ;) — kentaromiura

Try this... you have to use two backslashes to escape fully:

var jsonCallbackCode1 = eval("employees = { 'accounting' : [ { 'firstName' : 'Jo\\'\\'hn', 'lastName'  : 'Doe','age': 23 }]}");
            alert(employees.accounting[0].firstName);

Or of course you could just remove the apostrophes from the firstName altogether.

The parser is choking on The 'Jo''hn' because of the single quote. Escape it with \'

I believe

'Jo''hn'

is the problem.

So doesn't Ambrosia's technique with the double backslash do the trick, either?
