在需要时如何包括文件？

Question

I am using Laravel, sending Ajax requests to server. But I don't need some libraries like DropzoneJS (a library for Ajax uploading ), some images, some functions before some Ajax requests.

Is there any way to include them after some actions?
for example include a library when an element clicked

Is there any library to do this job?

Answer 1

If you need to pre-load required stuff you can use requirejs for that purpose.
Keep in mind that using it will "hold" your code until all the requirements are for-filled.

If you need to do some stuff after the AJAX is completed you can use promises or callbacks to capture the response and do what ever you need to do.
