Get mouse movement information

First, we need to get the coordinates of the mouse. we can add a User Function to document. onmousemove:




 
 
 
   
   
 
    Document. onmousemove = mouseMove;

Function mouseMove (ev ){
Ev = ev | window. event;
Var mousePos = mouseCoords (ev );
}

Function mouseCoords (ev ){
If (ev. pageX | ev. pageY ){
Return {x: ev. pageX, y: ev. pageY };
}
Return {
X: ev. clientX + document. body. scrollLeft-document. body. clientLeft,
Y: ev. clientY + document. body. scrollTop-document. body. clientTop
};
}		 
   
 
  

 






Mouse X Position:<input id=xxx type=text><br>Mouse Y Position:<input id=yyy type=text></body>
