看下效果

 

 

1.先在js文件中自定义全局组件

import './waves.css';//导入样式

const vueWaves = {};
vueWaves.install = (Vue, options = {}) => {
  Vue.directive('waves', {
    bind(el, binding) {
      el.addEventListener('click', e => {
        const customOpts = Object.assign(options, binding.value);
        const opts = Object.assign({
            ele: el, // 波纹作用元素
            type: 'hit', // hit点击位置扩散center中心点扩展
            color: 'rgba(0, 0, 0, 0.15)' // 波纹颜色
          }, customOpts),
          target = opts.ele;
        if (target) {
          target.style.position = 'relative';
          target.style.overflow = 'hidden';
          const rect = target.getBoundingClientRect();
          let ripple = target.querySelector('.waves-ripple');
          if (!ripple) {
            ripple = document.createElement('span');
            ripple.className = 'waves-ripple';
            ripple.style.height = ripple.style.width = Math.max(rect.width, rect.height) + 'px';
            target.appendChild(ripple);
          } else {
            ripple.className = 'waves-ripple';
          }
          switch (opts.type) {
            case 'center':
              ripple.style.top = (rect.height / 2 - ripple.offsetHeight / 2) + 'px';
              ripple.style.left = (rect.width / 2 - ripple.offsetWidth / 2) + 'px';
              break;
            default:
              ripple.style.top = (e.pageY - rect.top - ripple.offsetHeight / 2 - document.body.scrollTop) + 'px';
              ripple.style.left = (e.pageX - rect.left - ripple.offsetWidth / 2 - document.body.scrollLeft) + 'px';
          }
          ripple.style.backgroundColor = opts.color;
          ripple.className = 'waves-ripple z-active';
          return false;
        }
      }, false);
    }
  })
};

export default vueWaves;

2.导入 waves.css 样式

.waves-ripple {
    position: absolute;
    border-radius: 100%;
    background-color: rgba(0, 0, 0, 0.15);
    background-clip: padding-box;
    pointer-events: none;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
    -webkit-transform: scale(0);
    -ms-transform: scale(0);
    transform: scale(0);
    opacity: 1;
}

.waves-ripple.z-active {
    opacity: 0;
    -webkit-transform: scale(2);
    -ms-transform: scale(2);
    transform: scale(2);
    -webkit-transition: opacity 1.2s ease-out, -webkit-transform 0.6s ease-out;
    transition: opacity 1.2s ease-out, -webkit-transform 0.6s ease-out;
    transition: opacity 1.2s ease-out, transform 0.6s ease-out;
    transition: opacity 1.2s ease-out, transform 0.6s ease-out, -webkit-transform 0.6s ease-out;
}

3.在入口文件main.js 中导入定义好的 waves 组件

import vueWaves from '@/common/directive/waves'; // 组件所在路径
Vue.use(vueWaves); //全局使用

4.在页面el-button 中通过 v-waves指令使用

<el-button type="primary" size='mini' v-waves icon="el-icon-search" @click='search'>查询 </el-button>
