Javascript and Ajax function not working

Question

I am trying to update my database when the user clicks a certain link (links have different values, so when user clicks one link number goes up by 1, another by 2, and so on).

I need to submit a form to another page containing the data from #form with a variable behind it, but this function doesn't seem to be working.

JavaScript

function update_number(x) {

    $.ajax({
        type: "POST",
        url: "update_likes.php",
        data: $("#Form"+x).serialize(),
        dataType: "json",

        return false;
        };

HTML

<input type='image' src='...' onclick'update_number(2);' />

Any help appreciated.

what have you tried so far? this looks like a copy / paste code and that you do not know javascript at all. this place is not for teaching you how to properly code. its for giving answers to true questions. — GottZ

It seems that your JavaScript is not closed correctly.

Try changing your JavaScript with this:

function update_number(x) {
    $.ajax({
        type: "POST",
        url: "update_likes.php",
        data: $("#Form"+x).serialize(),
        dataType: "json",
        success: function(json) {
            alert( json );
            return false;
        }
    });
 }
