This article describes how jQuery achieves the effect of moving layers following the mouse. Share it with you for your reference. The specific analysis is as follows:
I. Basic Objectives
Write a layer that follows the mouse movement,
The current mouse position is displayed in the layer,

<! -- Allow this layer to be alignment in any way and free -->
<Div id = "mousePosition" style = "position: absolute;"> </div>

/* A pair of e. pageX and e. pageY can get the current coordinates of the mouse. Note that the e-Form parameter is used in the initial function declaration */
$ (Document). mousemove (function (e ){
Var x;
Var y;
Var xy = "<br> x coordinate:" + e. pageX + ", y coordinate:" + e. pageY;
X = e. pageX;
Y = e. pageY;
