Sending data with JavaScript to MySQL

Question

I am looking for a simple way to send data from client to server database. I exept a simple piece of code in java that sends data from client to server in any way.

For example in this code I want to store in my database how many times the button was pressed by some user(with some id, we use id to find a row in database and increment value in second column).

<html>
  <head>
    <title>test</title>
    <script language="JavaScript">
      function count(form){
        form.games.value=eval(form.num.value)+1;
      }
    </script>
  </head>

  <body>
    <?php
      $con=new mysqli(mysql_host,mysql_user,mysql_password,mysql_database);
      $sql="select * from Users where ID='".$_POST['id']."'";
      $result=$con->query($sql);
      $arr=$result->fetch_row();
      $val=$arr[1];
      echo "
        <form name=\"display\">
        <textarea class=message readonly=true disabled=true name=\"num\">{$val}</textarea>
        <input type=button value=\"Hit\" onClick=\"count(this.form)\">
      ";
    ?>
  </body>
</html>

I hope my question is not too broad this time.

First, it's called Javascript (one word), to make your questions more clear in the future. You could use jQuery's .get() function to send an HTTP GET request to a PHP page that would record the data onto the database. You can send along with it the data such as ID as the example on the jQuery page.

Basic flow:

User Clicks Button
jQuery Sends Get request to PHP
PHP Page Executes mysql command to record click
PHP returns successful (you can use a json_encode for the return) or failure.
Your Javascript tells the user that the command was sent successfully.
