先上代码,再上图片
。
写一下编程思想吧，大家都知道通过
odiv[sign].style.left = (event.clientX - odiv[sign].offsetWidth/2) + "px"; odiv[sign].style.top = (event.clientY - odiv[sign].offsetHeight/2) + "px";
这么两句就可以实现一个div的鼠标跟随效果，那么解析一下：
event.clientX/*点击事件后event对象产生的 鼠标X轴坐标*/ - odiv[sign].offsetWidth/2/*跟随鼠标的div自身的宽度除以2*/（其目的是为了让鼠标指针居中）
ok~ 那么我们已经可以做到1个div的鼠标跟随了，那么每隔N毫秒我们去调用这个函数，让下一个div跟随，如此往复，就可以做到这个炫酷的杀马特风格了。。。
SetInterval（）。。。大家都懂的 ，不多说了。。这个效果还是蛮绚丽的
当然这个效果用到了一些投机取巧的方法。。。11.gif （窃喜....不多说）
