Ok guys I know this question has been asked before but I am very new to PHP and JavaScript and hadn\'t even heard of ajax until i started looking for an answer to this question
Your code will not print to the page the way you have it set up; you're part of the way there, in that you have called the page, but the response needs to be handled somehow. If you open up the developer tools in Chrome, you can click on the Network tab and see the request and response to verify that what you coded is actually working, but now you need to put the response somewhere.
By passing a function as the second variable into $.get, you can make your request show up on the page. Try something like this:
$.get("backend.php", function (data) { $('body').append(data); } );
