vue

  1. 创建 waves.css文件

.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;
}

　　2. 创建 waves.js 文件

import './waves.css'
const context = '@@wavesContext'
function handleClick(el, binding) {
  function handle(e) {
    const customOpts = Object.assign({}, 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
    )
    const 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.documentElement.scrollTop ||
              document.body.scrollTop) + 'px'
          ripple.style.left =
            (e.pageX - rect.left - ripple.offsetWidth / 2 - document.documentElement.scrollLeft ||
              document.body.scrollLeft) + 'px'
      }
      ripple.style.backgroundColor = opts.color
      ripple.className = 'waves-ripple z-active'
      return false
    }
  }
  if (!el[context]) {
    el[context] = {
      removeHandle: handle
    }
  } else {
    el[context].removeHandle = handle
  }
  return handle
}
export default {
  bind(el, binding) {
    el.addEventListener('click', handleClick(el, binding), false)
  },
  update(el, binding) {
    el.removeEventListener('click', el[context].removeHandle, false)
    el.addEventListener('click', handleClick(el, binding), false)
  },
  unbind(el) {
    el.removeEventListener('click', el[context].removeHandle, false)
    el[context] = null
    delete el[context]
  }
}

　　3. 创建 index.js 文件

import waves from './waves'
const install = function(Vue) {
  Vue.directive('waves', waves)
}
if (window.Vue) {
  window.waves = waves
  Vue.use(install); // eslint-disable-line
}
waves.install = install
export default waves

　　4. 使用

使用的话 直接在div上使用v-waves标签即可
<div v-waves class="card-panel"> </div>
<script>
import waves from '@/directive/waves' //引入
export default { 
 directives: { waves } //注册
}
</script>
