How can i add some data to drupal setting object using drupal_add_js withing some ajax callback?
For example I have ajaxified flag link on my page, and have implemented hook_flag in my module, how can I add JS within this hook?
function hook_flag($action, $flag, $content_id, $account) {
...
drupal_add_js(array(
'my_module' => array('color' => 'green')
),
'setting'
);
...
}
drupal_add_js is designed to work when you are rendering a page, it doesn't really work for AJAX callbacks and it doesn't need to. If you want to modify the Drupal.settings data, you should do so within the JavaScript invoking the ajax call. It could look like this:
$.ajax({
url: "mydomain.com/url",
type: "POST",
dataType: "json",
data: $.param( $("Element or Expression") ),
success: function(json) {
Drupal.settings.data = json.data;
},
});
Drupal.settings?
drupal_add_js doesn't work properly in an AJAX callback. If you need to execute a JavaScript function within an AJAX callback, here's a way :
First, in your form, you have to create (you can just import it) the JavaScript function :
function my_module_form($form, &$form_state) {
// [...]
drupal_add_js(
'Drupal.ajax.prototype.commands.myFunction = function(ajax, response, status) {
// Whatever you want to do.
}',
'inline'
);
// [...]
return $form;
}
Then, in your AJAX callback, you need to call this function you created :
function my_module_my_ajax_callback($form, &$form_state) {
// [...]
$commands[] = array("command" => 'myFunction',);
// [...]
return array('#type' => 'ajax', '#commands' => $commands);
}
Hope it helps !
If you want the updated values of your variables Drupal.settings.my_module, you can use response data at ajaxComplete
(function($){
$( document ).ajaxComplete(function( event,response, settings ) {
console.log(JSON.parse(response.responseText)[0].settings.my_module));
});
})(jQuery);
