AJAX request fired multiple times

[rozsival]

Today, I implemented this neat library into my project. The implementation itself was very simple. However, one head-scratcher occurred. I have a form in which there are 3 dependent select boxes, each dependent on:

• the very first select box (without any dependency) in the form
• one checkbox toggling true / false variant
• value from previous dependent select box

When I make a change to any of registered parents, the AJAX request gets fired as many times as the count of all select boxes that need to be changed due to a change of their respective parents. Every change made to the form therefor takes a ridiculous amount of time and slows down the development and testing.

Is this a standard behavior or should this extension be able to get all the data in single request?

Hi, in dev speed is lazy (tracy reloaded request by request), its true. But in production mode its ok. I have forms with 5 dependent boxes and changes are instant.

@aleswita Thanks for your reply. I have tried it in production mode as well and yes, it is much faster. Anyway, I would like to know if it's intended that there are separate AJAX requests for each select box. The client-side code looks like it is expected behavior, I just want to be sure I'm not doing anything wrong.

Yes, its expected behavior.
