Vue封装全局组件

在src/components目录下创建自己的组件文件夹，例zkxUI

例如loading组件 需注意name属性命名组件 例zkxLoading

loading组件代码

<template>
  <transition name="zkxLoading" v-if="visible">
    <section>
      <div class="loading">
        <span></span>
        <span></span>
        <span></span>
        <span></span>
        <span></span>
      </div>
    </section>
  </transition>
</template>
<script>
export default {
  name: "zkxLoading",
  props: ["visible"],
  data() {
    return {};
  },
  methods: {}
};
</script>
<style scoped lang="scss">
.fade-enter-active,
.fade-leave-active {
  transition: opacity 0.5s;
}
.fade-enter, .fade-leave-to /* .fade-leave-active below version 2.1.8 */ {
  opacity: 0;
}
section {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: rgba(0, 0, 0, 0.3);
  z-index: 999;
  display: flex;
  align-items: center;
  justify-content: center;
}
.loading {
  width: 100%;
  text-align: center;
  /* flex-direction: column; */
}
.loading span {
  display: inline-block;
  width: 8px;
  height: 100%;
  border-radius: 4px;
  background: lightgreen;
  -webkit-animation: load 1s ease infinite;
  margin-left: 5px;
}
@-webkit-keyframes load {
  0%,
  100% {
    height: 40px;
    background: lightgreen;
  }
  50% {
    height: 70px;
    margin: -15px 0;
    background: lightblue;
  }
}
.loading span:nth-child(2) {
  -webkit-animation-delay: 0.2s;
}
.loading span:nth-child(3) {
  -webkit-animation-delay: 0.4s;
}
.loading span:nth-child(4) {
  -webkit-animation-delay: 0.6s;
}
.loading span:nth-child(5) {
  -webkit-animation-delay: 0.8s;
}
</style>

组件注册代码 index.js

import zkxLoading from "./zkx-loading"

const components = [
    zkxLoading
]

const install = function(Vue) {
  components.forEach(component => {
    Vue.component(component.name, component);
  });
};

export default install

在main.js里引入

在页面中直接使用
