Question

Javascript Multi-level array of JSON objects - how to access key-value pair in second level or higher

Answer 1

+3 A:

This worked OK for me:

myList[1].children[0].childname

This is also OK:

myList[1]["children"][0].childname;

In full,

<html>
<body>
<script>
var myList = [
    {title:"Parent1",
        children:[{childname:"Child11"},
                     {childname:"Child12"}],
        cars:[{carname:"Car11"},
              {carname:"Car12"}]
    },
    {title:"Parent2",
        children:[{childname:"Child21"},
                     {childname:"Child22"}],
        cars:[{carname:"Car21"},
              {carname:"Car22"}]
    }
];
alert (myList[1].children[0].childname);
</script>
</body>
</html>
