jQuery triggerHandler approach
In my first experiment, I used the jQuery
triggerHandler() featured in order to create something like
add_action() as well as
add_filter(). In other words, the
$( document ).triggerHandler( 'my_custom_event') and the
$( document ).on( 'my_custom_event', ... ).
However, this approach has some limitations. First of all, is not possible to handle the priority feature: executing sequence. The function add_action(), in fact, supports the priority param in order to run a hook in a specified order. Also,
triggerHandler() can return a result. This is great for “emule”
add_filter() function but could make a mess.
- A real stack/queue for actions and filters
- Priority support for actions and filters
- Arguments variable
- Logical split between actions and filters
Have a look to an example of use below:
