accessing array object in json data format

Question

postItem : [{
    id: 1,
    content: 'string',
    date: '1 Jan 2014',
    category: '1'

    },

    {
    id: 2,
    content: 'string2',
    date: '14 Jan 2014',
    category: '2'

    }]

postItem[0].content doesn't work to select the first array's content object. Am I doing something wrong?

Make sure you've parsed the JSON, and aren't just trying to index a string. — rvighne

You must see that postItem is a property also. Supposing you have returned just one object in you JSON data, that is data = {postItem, ... ,} then to access postItem itself you must refer to the object that it belongs (in that case data).

So, if you do postItem[0].content you'll get an error, because postItem doesn't exist in that scope. Now, if you do data.postItem[0].content then you'll get correct, since you are accessing the variable where it really exists.
