I have an HTML input with a function and parmeter set to it like so

<input onclick='myFunc($count)' type='button' value='ClickMe'>;

I also have script references to JQuery and my script file

 <script src="jquery.js"></script>
 <script src="myscript.js"></script>

Inside my myscript.js file I have the contents as such

function myFunc(x) 
 alert(x);

 $(document).ready(function() 
 $.ajax(
 url: "myphp.php",
 method: "post",
 data: param1: "x" ,
 dataType: "text",
 success: function(strMessage) 

 
 )
) 

Here is my myphp.php file

<?php

 $param1 = $_GET['param1'];
 echo $param1;
?>

As you can see in the javascript file, I have alert(x); to test that the function is grabbing the $count variable and so far that is working (the correct value appears in the alert box). However, I want to pass that x parameter to the PHP script but my PHP script won't echo anything, I assume the line where I have param1 is wrong. Any tips?

  remove the quotes from data: param1: "x" , in your javascript and add alert(strMessage); inside of the success: function( strMessage ) curly braces.

  I followed your instructions and removed the alert(x); function underr myFunc() and when I click the button I get an alert but nothing inside the alert. This would mean that either the parameter is not being passed in AJAX and/or PHP? It is kind of hard to test if AJAX is calling the PHP file from within the web browser.

You're making the XHR with POST method

method: "post",

and youre looking for it in the GET array

$_GET['param1'];

Change either to post or get (keeping in mind your scenario) and you should be good imo.
