using ajax in a component

Hi, I don’t understand well enough how to use AJAX in a BP component.

I’ve tryed to look at the existing plugins (bp-messages, bp-groups) but I don’t find any references of to the functions set in the bp-..-ajax.php files elsewhere that the definition of the function itself.

e.g. look at directory-groups.js : we have such things.
```
jQuery.post( ajaxurl, {

action: 'directory_groups',

'cookie': encodeURIComponent(document.cookie),

'_wpnonce': jQuery("input#_wpnonce-group-filter").val(),

'letter': letter[1],

'page': 1

},
```
What does ‘directory_groups’ refers to ?

There is no directory_groups function…

Or maybe does it refers to that function of the ajax file ?
```
function bp_core_ajax_directory_groups() {

global $bp;



check_ajax_referer('directory_groups');



load_template( TEMPLATEPATH . '/directories/groups/groups-loop.php' );

}

add_action( 'wp_ajax_directory_groups', 'bp_core_ajax_directory_groups' );
```
I don’t understand how this works. Really… If someone could help me ?

And what is “check_ajax_referer” ?

You’ve got it correct. The action from the js is taken and called with an action prefixed with “wp_ajax_”, just like above.

Check_ajax_referer() checks that a valid nonce was passed with the request – to find out more about nonces, see here.
