PHP Script on back-end when click on button using JQuery

Question

I'm working on joomla environment. I would like to run small php script by click on button event from JQuery reason I would like to use JQuery is I cannot modified existing component. Current component adding some values on Database from webpage. I would like to do same thing but from back-end with out notify any thing from another PHP file. I was trying something as code but it's not working.

Is there any other way.? What is wrong in code.?

 <script type="text/javascript">
    jQuery(document).ready(function(){
    jQuery('#submitButton').click(function(){
    $.post("/automate/UpdateMySql.php");
   });
  }
</script>

You were missing a dot and bracket(with semi-colon) at the end. As per the comments if you want to just Update Date And Time. You can post any random variable to UpdateMySql.php and then Create Date And Time there.

<script type="text/javascript">
var clicked = 0;
jQuery(document).ready(function(){
 jQuery('#submitButton').click(function(){
  clicked = 1;
  jQuery.post("/automate/UpdateMySql.php" , { click : clicked });
 });
});
</script> 

In UpdateMySql.php write.

$clicked = $_POST['click'];
if(isset($clicked) && !empty($clicked)) {
$today = date("Y-m-d H:i:s");
$query = "UPDATE table_name date_time=".$today." WHERE anything = 'anything'";
 if($query) {
   return 'Updated';
 } else {
   return 'Something Went Wrong';
 }
}
