使用js连接到db并隐藏元素

Question

I want to check if the value true is present in a db and if present i want to hide a partcular id using javascript.

I know both parts - how to check database and hide elements with js.

the question is - how do i integrate both parts?

Ex - Check if in table "Tutorials", the value "true" is present or not. If yes, document.getelementbyid(box).style.display :none;

How do i integrate both? thanks.

Answer 1

Nest your php within your javascript call. The PHP will get processed at the server side, and will return a boolean, then use that to be part of an if block to decide what to hide

if (<?php Check database and return boolean ?>){
    $('#box').hide();
}
