Using JSON POST Request

I'm attempting to use JSON to initiate a POST request to an API.

I've found some example code, and before I get too far I wanted to get that working, but I'm stuck...

<html>
<head>
<script type="text/javascript">
function JSONTest()
{
requestNumber = JSONRequest.post(
    "https://example.com/api/",
    {
        apikey: "23462",
        method: "example",
        ip: "208.74.35.5"
    },
    function (requestNumber, value, exception) {
        if (value) {
            processResponse(value);
        } else {
            processError(exception);
        }
    }
); 
}
</script>
</head>
<body>

<h1>My JSON Web Page</h1>


<button type="button" onclick="JSONTest()">JSON</button>

</body>
</html>

This is a .html file, which I am running in chrome. Nothing happens when I click the button...

I think I'm missing a piece of javascript which interprets the JSON response and can be displayed? otherwise any other advice?

An example using jQuery is below. Hope this helps

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<title>My jQuery JSON Web Page</title>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">

JSONTest = function() {

    var resultDiv = $("#resultDivContainer");

    $.ajax({
        url: "https://example.com/api/",
        type: "POST",
        data: { apiKey: "23462", method: "example", ip: "208.74.35.5" },
        dataType: "json",
        success: function (result) {
            switch (result) {
                case true:
                    processResponse(result);
                    break;
                default:
                    resultDiv.html(result);
            }
        },
        error: function (xhr, ajaxOptions, thrownError) {
        alert(xhr.status);
        alert(thrownError);
        }
    });
};

</script>
</head>
<body>

<h1>My jQuery JSON Web Page</h1>

<div id="resultDivContainer"></div>

<button type="button" onclick="JSONTest()">JSON</button>

</body>
</html>

Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).

Otherwise, you might want to go with another JS library like jQuery or Mootools.
