Question

I have this string that I generate in JAVA and pass to javascript to be parsed.

This works:

var childString = '[{title: "Item 1"},{title: "Folder 2", isFolder: true,children: [{title: "Sub-item 2.1"},{title: "Sub-item 2.2"}]},{title: "Item 3"}]';
var childArray = eval(childString);

But I’ve read everywhere that eval == evil so i’m looking into the JSON way of parsing.
I tried using JSON.parse(childString), but I got an error.

How could I do this the JSON way?

Thanks!

You can’t parse it using JSON.parse because your json string is invalid. It needs to be as follows:

var childString = '[{"title": "Item 1"},{"title": "Folder 2", "isFolder": true,"children": [{"title": "Sub-item 2.1"},{"title": "Sub-item 2.2"}]},{"title": "Item 3"}]';
