Hello,

I am developing a module (Drupal 6.4) which shows a list of online servers. The list is refreshed each X seconds. I used the book "Learning Drupal 6 Module Development" and inside I found the perfect trick. I created an empty page which contains 2 blocks.

Block A: contains the server list and using JSON/jQuery it gets refreshed each X seconds.

Block B: contains a form with 3 check boxes.

So far I am only using block A and everything works as expected. The server list is shown and gets refreshed each X seconds. The goal is to allow the check boxes in Block B to control which type of online servers are listed. For this I needed something like on-toggle -> set variable. I don't want to use any real submit form stuff but the status the check box should change and I should be able to perform a variable_set().

Thanks to someone on the Drupal IRC channels I got the following piece of code:

$('input[@type=checkbox]').click(function() { $.ajax({ type:'POST', data:{val:$(this).attr('checked')}, url: 'path_to_a_drupal_menu_item', dataType: "json", success:function(json) { alert(json.result); } }); });

I am not sure however how this works. I assume I need to put it in my module's .js file and it will call the 'path_to_drupal_menu_item' but how is the result processed? Is it passed as an argument and can I fetch it and perform a variable_set() or does it simply update the page itself and changes the html element 'checked' of the check box?

Any help and/or pointers towards a correct solution are greatly appreciated.
