How to pass jquery variable to database and output value??

How to pass jquery variable to database and output value??

Hello -

I am trying to set up a non-cookied counter which will stay saved at a current value for all visitors coming onto the site (and can increase the counter).

It is here :

http://www.kennyrosenberg.com/?page_id=19

The likes are at 0 when you first go to the page but I always want them to be saved and increasing whenever someone clicks like.

The value of the variable is "i"

$(function() {
    // generate markup
     
       $("#rating").text("Likes : " + 0);
     var i = 0;
      
       // add markup to container and apply click handlers to anchors
       $("a#add").click(function(e){
         // stop normal link click
         e.preventDefault();
         i++;
         // send request
         $("#rating").text("Likes : " + i);
       });

    // generate markup
         
       $("#norating").text("Dislikes : " + 0);
     var n = 0;
      
       // add markup to container and apply click handlers to anchors
       $("a#remove").click(function(e){
         // stop normal link click
         e.preventDefault();
         n++;
         // send request
         $("#norating").text("Dislikes : " + n);
       });

});

<span id="rating" style="font-size:20px;">


</span>

<span id="norating" style="font-size:20px;">


</span>

<a href="#" id="add">Like This</a><br />

<a href="#" id="remove">Dislike This</a>
