vue element-plus Button 按钮 添加 波浪纹

1、src/directives 创建waves.ts

import { ObjectDirective } from 'vue';

const Waves: ObjectDirective = {
  mounted(el) {
    let tempClass = el.getAttribute('class') + ' button-waves';
    el.setAttribute('class', tempClass);
    let node = document.createElement('div');
    node.setAttribute('class', 'anim');
    el.appendChild(node);
  }
};

export default Waves;

2、main.ts引入

import waves from './directives/waves';
//app.use之前注入
app.directive('waves', waves);

app.use(VueLazyload, {
  preLoad: 1.3,
  error: errorimage,
  loading: loadimage,
  attempt: 1
});

3、使用 元素上直接添加v-waves

   <el-button v-else v-waves class="getPhonecode">
    {{ countdownSeconds }} {{ $t('personalData.Secondm') }}
    </el-button>

public.scss
