How to make the function work in dynamics?

Question

JavaScript

Let's say there is a table and buttons for deleting, adding rows / columns. When 1 cell remains, hide the buttons.
The function has the condition "if 1 row - hide the button, 1 column - hide the button." The function then works correctly - but only for the initial state of the table. You can, of course, call the function in the buttons, but it seems to me that there is an easier option.

Answer 1

Every time you click delete row/add row you should fire a callback that will re-run your function that hides/shows the buttons.

Answer 2

No. What do you mean "function worked in dynamics"? Is there any code that needs to be executed? Function code? Duck call the function when needed. There is no magic here.

Answer 3

It turns out that when you add new elements, events are not attached to them. Well, or in the function that hides / shows, the table is cached in its original state.
After adding a new element, it is necessary to call a function that will hang an event on a new element, or simply recheck all elements, taking into account those just added to the DOM, and hang a handler on all elements.
