提示
本文是个人的一点小笔记,用来记录开发中遇到的轮播图问题和vue-transition问题.
会不断学习各种轮播图添加到本文当中
也有可能会上线,方便看效果
开始制作
超简易呼吸轮播
简单粗暴的使用vue transition制作的轮播图,这里解释一下原理
动画效果就像车辆穿行隧道,定好初始位置/最终位置,设定好运动规则,它就自动开了.
在下面的实例中,我们设定好了运行规则,和分别两种状态,它就开始自动运行了.
大家可以对照上图看一下,很容易的,图中的v代表transition标签中的name字段

双翼渐变式轮播
在这个轮播图里,我们transition的标签是动态的,在翻页函数运行的时候,会改变它的name,从而展现不同的动画效果
