How can I use javascript timing to control on mouse stop and on mouse move events
Date : March 29 2020, 07:55 AM
I wish did fix the issue. So I have a control (a map) on an aspx page. I want to write some javascript to onload setup the following: , That is a tricky one. A little bit of tinkering resulted in this: function setupmousemovement() {
var map1 = document.getElementById('Map_Panel');
map1.onmousemove = (function() {
var timer,
timer250,
onmousestop = function() {
// code to do on stop
clearTimeout( timer250 ); // I'm assuming we don't want this to happen if mouse stopped
timer = null; // this needs to be falsy next mousemove start
};
return function() {
if (!timer) {
// code to do on start
timer250 = setTimeout(function () { // you can replace this with whatever
// code to do when 250 millis have passed
}, 250 );
}
// we are still moving, or this is our first time here...
clearTimeout( timer ); // remove active end timer
timer = setTimeout( onmousestop, 25 ); // delay the stopping action another 25 millis
};
})();
};

How we move a label when mouse click on it and when mouse key up then stop moving inside a group box
Tag : chash , By : Ir0nh1de
Date : March 29 2020, 07:55 AM
seems to work fine The e.Location gives you a mouse position relative to the control that is being clicked. So to fix that, instead of
label13.Location = e.Location;
var pos = this.PointToClient(Cursor.Position);
label13.Location = new Point(pos.X - offset.X, pos.Y - offset.Y);` offset = e.Location;
