Why am I getting $ is not defined error?

Question

I need to call a php file through ajax. I tried following:

<html>
<script type="text/javascript">

setInterval(function(){
test();
},3000);

function test(){     
$.ajax({
    type: "POST",
    url: "GetMachineDetail.php",
    data: "{}",
    success: function(response){
         alert("suceccess");}
    });
}

It's simple javascript jquery calling... But I've got an ajax not found error.

Question: How could I solve this issue?

jQuery is required for `$.ajax`, where do you include the lib — Lawrence Cherone, Oct 26 '13 at 09:48
try **jQuery.ajax**, well as the above comments , are you including jQuery file or not ? — Deepanshu Goyal, Oct 26 '13 at 09:49

$ is a (poorly named) function supplied by the jQuery library. You need to include that library in your page before you try to use it.

You can get it from the jQuery website (where you will also find instructions on how to use third-party hosted versions).
