Trigger mouse click by window offset in javascript [duplicate]

Question

How can I trigger mouse left button click by specifying X and Y pixels offset from upper left website corner via JavaScript?

Answer 1

Well, using just Javascript as you asked, you can use mouse events, as you can read X and Y properties to get coordinaties from the event object, for sample:

// mouse move
document.body.onmousemove = function(e) {
   var x = e.X;
   var y = e.Y;
   console.log(e);
}

// mouse down
document.body.onmousedown = function(e) {
   var x = e.X;
   var y = e.Y;
   console.log(e);
}

To simulate an mouse click, you can call the event onmousedown manually, but you have to provide the event parameter (passing the coordinates, etc..), for sample:

document.body.onmousedown({X:120, Y:120 /* other properties */});
