从特定的javascript对象属性获取价值

Question

I'm trying to access the locations array from my javascript object and store it.

data = [{
          "id":123,
          "name":"John",
          "locations":["Smith","McHale","Residence 4"]
        }]

I've tried things like:

locations = data['locations'] and data.locations . But both return undefined . What am I doing wrong? How can I just grab the locations array to store in its own variable? (Not using Jquery) Thank you for your help advance!

Answer 1

Because it's array first, and only then object:

locations = data[0].locations;

You could avoid [0] this if you remove [ and ] from your data declaration.
