AngularJS parsing JSON

Question

I have the following JSON:

at http://localhost:3000/folder/1234567

[

   {

      "_id": "543e95d78a1cec2a38ed53ec"

   },

   {

      "_id": "543e95d78a1cec2a38ed53f1"

   }

]

And I want to get all the _id.

So, I am doing something like:

$http.get('http://localhost:3000/folder/' + folderId)
                        .success(function (response) {
                    console.log("response"+ response);
                    console.log("response id"+ response.id);

But I have:

response [object Object],[object Object]
response id undefined

How can I fix to get the _id ?

Thanks for your help !

The response is an Array so you have to loop over it. Which _id do you need? — Razvan

it depends what you want to do with your data. if you want to display them, just put the data to your scope and use ng-repeat in your view. or if you want to do something else, you can use angulars foreach or so. — Raphael Müller

To get all the Ids in reverse order:

var allIds = [];

$http.get('http://localhost:3000/folder/' + folderId).success(function(res) {
    for (var i = res.length-1; i>-1; i--) {
        allIds.push(res[i]._id);
    }
    // this prints an array with all the Ids 
    console.log(allIds);
});
