Hello! I recently started studying DataTables. Stopped with dependent fields. I looked at a lot of examples and still a lot is unclear.
There is a classic example:
https://datatables.net/blog/2017-09-01
It is often pointed at. And it is important for me to understand.
It would be nice to decipher it a bit:
1. I don't understand: how many tables are there in the Database? As far as I understand 4:
Table 1- for filling in
Table 2 - " Continents»
Table 3 - " Countries»
Table 4 – " id_Сontinent-id_ Country»
2. I really want to see the "JavaScript" code
3. editor.dependent ('continent', '/ api/countries' );
the Second argument «/ api/countries» what is it?
4. Do I understand correctly that in this example there are actually two Server script (PHP files)? I'd like to see both.
I'm sorry, I'm still at the beginner level and I need your help.
