Question

I have a javascript array written like this…

var json = [
    {"id":"1", "title":"Test 1", "comment":"This is the first test"},
    {"id":"2", "title":"Test 2", "comment":"This is the second test"}
];

what I am trying to do is get each one of the ids.

I have been trying this

for(x in json[0]){
    alert(x.id);        
}

But no luck, can someone point me in the right direction? Please and thank you 🙂

Answer 1

x in your example is giving you the indexes of you array, not the objects. You could do:

for(x in json) {
    alert(json[x].id);        
}

but to loop through an array you’re really better off with a “regular” for loop

for (var i = 0, max = json.length; i < max; i++) {
    alert(json[i].id);
}
