Question

Hi I am developing Android application using Titanium.I want to change value of particular attributes of json object.I tried following code :

var row_jsonfeed = this.responseText;
var jsonfeed = eval('('+row_jsonfeed+')');    

my jsonfeed object look like this :

{"feeds":
[
   {"username":"abc","user":"abc","feed":{"description":"dss","id":660,"user_id":1}},
   {"username":"bcd","user":"bcd","feed":{"description":"dddd","id":659,"user_id":1}}
]
}

I want to change username value so I tried like this:

jsonfeed.feeds[0].username = "xyz";
alert(jsonfeed.feeds[0].username);

But it’s not working.It not giving me changed value of username.Any other alternative way to do this. Instead of eval I also tried JSON.parse but that also not working.So i need proper way to do this.Thank you in advance.

I think the problem is with your call to eval. You forgot to concatenate your parens:

eval('(' + row_jsonfeed + ')');
