Javascript / JQuery / PHP / Ajax - Drupal 6
Update: 11/23/2011
This is a very popular topic, so I have decided to add a little more detail and hopefully clear up the process for some.
Visit the following links for a live example:
An example module is attached below if anyone wants to take a closer look at the code.
This one was tricky:
While using javascript / jquery to call ajax functions backed by php I wanted to attach certain javascript behaviors to the new ajaxed content. In this case simply a resizable textarea in a form. This is how I got Drupal.attachBehaviors to work.
function testingBehaviors(action) {
var url = '?q=testing/ajax/form/' + action;
$('#test-form').load(url, function(){
Drupal.attachBehaviors(this);
});
}
in the php file testing.module ->
function testing_init() {
drupal_add_js(drupal_get_path('module', 'testing') . '/scripts/testing.js');
// will not work without the required js files loaded...
drupal_add_js('misc/textarea.js');
}
The second step ensures that the required javascript files are loaded when the page is first loaded, before the ajax call.
