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"}]

possible duplicate of Length of Javascript Object (ie. Associative Array) –  domokun Jul 4 at 13:17
    
This is so basic that you could have found it in 30 seconds straight. It's not even Angular... –  domokun Jul 4 at 13:18

@domokun it is a regular array not an object –  Ilan Frumer Jul 4 at 13:19
    
Even simpler... –  domokun Jul 4 at 13:21

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"}]
