enqueue scripts / setup ajax

To enqueue scripts you can use the enqueueScript() method.

$this->enqueueScript(
    $sUrlOrPath, // source url or path
    $sPageSlug     // page slug
);

For CSS, use enqueueStyle().

$this->enqueueStyle(
    $sUrlOrPath, // source url or path
    $sPageSlug     // page slug
);

As for Ajax, an easy way I can think of is to use jQuery and send an Ajax request to the currently loading page with additional url query key-values. Then in the start() meethod, which is a user constructor of the factory class you extend, check the $_GET array and if a desired key is set, perform a certain task and return relevant output.

If you need more help regarding Ajax, create a new topic. Let’s resolve the enqueuing issue you are having first.
