Using JSON in jQuery

Let's take a closer look at the .getJSON function.

jQuery.getJSON(

url, //the location of the data data, //if you need to send anything to the service POST function(){

//callbackfunction

The data parameter is used if you need to POST data to the URL (you can do this in a query string or array object). The call back function is not required, unless you're calling a URL from a server other than your own.

Let's now take a look at putting .getJSON to use in our WordPress site.
