Topic: Datatable scroll back to the origin position after update

szaiftamas priority asked 1 month ago


Expected behavior I would like to scroll back the vertical scroll bar after update the content without any trick. That trick what I found is time based, so it is absolutely dangerous! Do you have any better idea?

Actual behavior If I scroll down to the middle of the table content, and I after update the table, the scroll position will be on the top of the table and I need a trick now to scroll back.

Resources (screenshots, code snippets etc.)

var scrollTop = 0;

I can get the position with

scrollTop = table_el.querySelector('.datatable-inner').scrollTop;

but after the render, I need a setTimeout to the scroll back can be work

table_el.addEventListener('render.mdb.datatable', () => {
  setTimeout(setScroll, 100);
});

function setScroll() {
  var el = table_el.querySelector('.datatable-inner');
  el.scrollTop = scrollTop;
  var el_rail = table_el.querySelector('.ps__rail-y');
  el_rail.style.top = scrollTop + "px";
}
