how to prevent focus event in IE when mousedown happens

Question

event.preventDefault(); return false; event.stopPropagation();

any of them can prevent focus event from happening when I trigger a mousedown event in Fi

Answer 1

The best solution I've found during my investigation is call preventDefault and stopPropagation functions not on "mousedown" event but on "pointerdown" instead.

Looks like any browser triggers "pointerdown" event before "mousedown" event and preventing "pointerdown" event prevents focus as well.
