Question

I have the following code that gets the first ‘name’ in an array called ‘feeds’ within my JSON, I would like to now loop through the JSON and get each name. I haven’t been able to get that loop to work.

JSON:

{
    "title": "Testing",
    "created_at": "2011-10-05T16:23:26.217Z",
    "feeds": [{
        "0": {
            "name": "twitter",
            "key": "person1"
        },
        "1": {
            "name": "twitter",
            "key": "person2"
        },
        "_id": "4e8c847e02edc10035000003"
    }]
}

This gets the first title successfully:

$.getJSON(getthisshit, function (myJson) {
    var myfeed = myJson.feeds[0][0].name;
    alert(myfeed);
});

I tried to loop through doing something like this, but have not been able to get it to work:

$.getJSON(getthisshit, function (myJson) {
    $.each(myJson.feeds, function (i, item) {
        alert(item.name);
    });​
});

Answer 1

use for in construction

for (var i in json.feeds[0]) alert(json.feeds[0][i].name);
