Question

I am currently creating a system where it has to be possible to check/uncheck a checkbox. Everytime it changes status I need jQuery to make an AJAX call to a page, that updates the database.

How can I do this?

For example you can do it like this:

First you have to look if the checkbox is checked:

$("#yourSelector").live("click", function(){
        var id = parseInt($(this).val(), 10);
        if($(this).is(":checked")) {
            // checkbox is checked -> do something
        } else {
            // checkbox is not checked -> do something different
        }
});

You can load specific content via Ajax:

$.ajax({
                type: "POST",
                dataType: "xml",
                url: "path/to/file.php",
                data: "function=loadContent&id=" + id,
                success: function(xml) {
                    // success function is called when data came back
                    // for example: get your content and display it on your site
                }
});
