Need javascript code for button press and hold

Question

I\'d like a short smallest possible javascript routine that when a mousedown occurs on a button it first responds just like a mouseclick and then if the user keeps the butto

Answer 1

When the button is pressed, call window.setTimeout with your intended time and the function x, and set the timer again at the end of x but this time with a smaller interval.

Clear the timeout using window.clearTimeout upon release of the mouse button.
