Get size of JSON array in AngularJS

Question

I am using AngularJS to render html page doing ajax call, which returns json file.

How to get count of id's in below JSON using angularjs?

[{"id":1,"Name":"Apple"},
 {"id":2,"Name":"Mango"},
 {"id":3,"Name":"Banana"}
 {"id":4,"Name":"Coconut"}
 {"id":5,"Name":"pineaple"}
 {"id":6,"Name":"Orange"}
 {"id":7,"Name":"Guava"}]

Answer 1

You don't need Angular to get the length of that.

In this case, your parsed JSON is a simple array, you can get the length with:

obj.length

assuming that obj contains your parsed JSON as such:

var obj = [{"id":1,"Name":"Apple"},
{"id":2,"Name":"Mango"},
{"id":3,"Name":"Banana"}
{"id":4,"Name":"Coconut"}
{"id":5,"Name":"pineaple"}
{"id":6,"Name":"Orange"}
{"id":7,"Name":"Guava"}]

Answer 2

var json=
[{"id":1,"Name":"Apple"},
{"id":2,"Name":"Samsung"},
{"id":3,"Name":"Nokia"}
{"id":4,"Name":"Motorola"}]

  var count = Object.keys(json).length;
  console.log(count);

Answer 3

In your HTML, lets say your array is "comments" (a common use-case):

{{ comments.length }}

You can also do a ng-hide="{{ comments.length}}" on an element that says something to the effect of "no comments".
