Getting length of array with attributes

Question

So, I have this array with attributes and i want to get its' length. In this case the array length should be 2 since there are only 2 "items"

 {"items":[{"value":"2","valor":0,"name":"Limpeza"},
 {"value":"6","valor":0,"name":"TECREMOVE"}]}

I've already tried exist.length but it returns undefined. How can i get its' length?

Answer 1

var myObj = {"items":[{"value":"2","valor":0,"name":"Limpeza"},
 {"value":"6","valor":0,"name":"TECREMOVE"}]};
var arrLength = myObj.items.length;

myObj.items - is the array, myObj.items.length - length of that array.

Answer 2

You're having an object which one of it's properties with the name items is an array with the length of 2.

Try:

var data = {"items":[{"value":"2","valor":0,"name":"Limpeza"},
 {"value":"6","valor":0,"name":"TECREMOVE"}]};
var len = data.items.length;
