Calling a php function using ajax/javascript

Question

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

Answer 1

It does nothing becuase you don't do anything with the result. My guess is that in the example you took, it does some work and doesn't show anything to the user. So if you just had some stuff you wanted to run on the server without returning any output to the user, you could simply do that, and it would work.

Example from jQuery's .get() documentation

What you do:

Example: Request the test.php page, but ignore the return results.

$.get("test.php");

What you want to do:

Example: Alert out the results from requesting test.php (HTML or XML, depending on what was returned).

$.get("test.php", function(data){
    alert("Data Loaded: " + data);
});
