As the title describes we’re going to look at making cross domain ajax requests using JSONP I’m also going to show you how to get data from a MySQL database and encode it into a JSON string which can be parsed using JavaScript. JSON stands for JavaScript Object Notation and essentially its a method which allows us to execute cross domain ajax requests without too much fuss. This post really follows on from my article about scraping content from a page but also allows you to send and receive GET variables through the JSON request.
