animation实现一个搜索扩散动效
简单分析一下
1.旋转的线,我们设置他的旋转位置从他的左下开始转动就ok了,再把最中的的圆层级设置高一点,就可以遮挡住线的一部分,看起来就是旋转的线在绕着中心的圆旋转。
2.闪现的点,控制百分比来实现展示顺序,比如我设置的3s要执行完一次闪烁。

上代码

html结构如下

<div class="no-warning" v-show="true">
                    //这是最外层圆形扩散
                    <div class="out-circle"></div>
                    <div class="w1">
                        //这是旋转的那个线
                        <div class="line"></div>
                        //这是跟着线走的阴影
                        <div class="cir-shadow">
                           //这是一层层圆
                            <div class="w2">
                                <div class="w3">
                                    <div class="w4">

                    </div>
                    //这些都是闪烁的圆
