If I have a JSON file named names.json with:

{\"employees\":[
    {\"firstName\":\"Anna\",\"lastName\":\"Meyers\"},
    {\"firstNam

    In the jQuery code, you should have the employees property.

    data.employees[0].firstName

    So it would be like this.

    <html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
</head>
<body>
<script type="text/javascript">
    $.getJSON("names.json", function(data) {
        console.log(data);
        $('body').append(data.employees[0].firstName);
    });
</script>
</body>
</html>

    Of course you'll need that property for the non jQuery version too, but you'd need to parse the JSON response first.

    Also keep in mind that document.write is destroying your entire page.

    If you're still having trouble, try the full $.ajax request instead of the $.getJSON wrapper.

        $.ajax({
        url: "names.json",
        dataType: "json",
        success: function(data) {
            console.log(data);
            $('body').append(data.employees[0].firstName);
        },
        error: function(jqXHR, textStatus, errorThrown) {
            console.log('ERROR', textStatus, errorThrown);
        }
    });
