Javascript Multi-level array of JSON objects - how to access key-value pair in second level or higher
Question
Consider the following array of JSON objects:
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"}]
}
];
How does one access the "Child21" in javascript? The following options didn't work:
var myString = myList[1].children[0].childname; //Does not work
var myString = myList[1]["children"][0].childname; //Does not work

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>

var myString = myList[1].children[0].childname;
In FireFox's Firebug works

这确实有效......
alert(myList[1].children[0].childname);

Your first option...
var myString = myList[1].children[0].childname;
should work just fine.
