这个函数是求如图蓝线的长度 黑色是当前窗口 绿色是hover的元素
function move( ev , bool) {
var top = $(this).offset().top
var bottom = top + $(this).height()
var left = $(this).offset().left
var right = left + $(this).width()
这个函数是求相对于当前页面 hover元素的四条边的距离
然后计算
var sT = Math.abs(y - top), //鼠标位置到hover元素顶部的距离
sB = Math.abs(y - bottom), //底部
sL = Math.abs(x - left), //左边
sR = Math.abs(x - right) //右边
var a = Math.min( sT , sB , sL , sR ) //然后在这4个距离里面选出最小值 变量a 就是距离最短的值
