How to modify on_mouse_move function

[john_woo]

Hi,

If what I want from the on_mouse_move function is, trigger another
function in two case:
1. when the mouse holds at same position for 1 second;
2. when the mouse fully stop;

in other cases (when mouse keeps moving) don't trigger that function.

Can any one tell how to implement this?

With each mousmove detected start a setTimeout delay of 1 sec, after
resetting the last one.

If the delay fully times out, start your function.

2. when the mouse fully stop[s?];

What is that, you will have to define that, no trigger for how long,
three days perhaps?

It is the same as above.

in other cases (when mouse keeps moving) don't trigger that function.

Yes, it is elementary.

you won't be able to tell during that 1 second, whether the mouse
stays in same position (namely X/Y never changed, the case that mouse
moves away and move back doesn't count);
The question is clear that triggering another function only when the
mouse stays for 1 second.

Wrong, the mouse has moved if an onmousemove event was triggered.
Testing where the mouse is in x/y is not necessary nor usefull.

mouse stays for 1 second.

Indeed.

The question is not about the on_mouse_move definition. say mouse
moves from

A -> B (move slowly) -> C (here stop for 1 second then continue to
move) -> D, and fully stops at D

thus the movement triggers event at A, B and C. my question was, I
wanted to trigger another function only when the mouse at C, not at B
nor D;
the setTimeout is used to delay action, regardless of whether mouse
stop 1 second then move again or keep moving without stop.

No that was not the Q.

The Q was:

stop 1 second then move again or keep moving without stop.

No, you are looking at my programming advice the wrong way.

I'll refrase:

Every time the mouse moves, the setTimeout is reset and restarted.
Only if there is no movement for one second, setTimeout times out and
your function is executed.
