功能概述:项目里有很多表格,希望表格加载动效好看一点,有多少列就显示多少列在加载,做成公共组件。效果:【Vue组件】表格骨架屏

实现方式:在公共组件文件夹中创建vue,编写后,在main.js中引入即可。loadSkeleton.vue

<template>
  <el-skeleton style="width: 100%" animated>
    <template slot="template">
      <div class="skeleton">
        <div class="skeleton-th">
          <el-skeleton-item
            v-show="haveLeftNumber"
            variant="h1"
            class="small"
            :style="{ margin: columns < 10 ? '0 32px' : columns < 15 ? '0 12px' : '0 6px' }"
          />
          <el-skeleton-item
            variant="h1"
            v-for="t of columnArr"
            :key="t + 'loadSkeleton-th'"
            :style="{ margin: columns < 10 ? '0 32px' : columns < 15 ? '0 12px' : '0 6px' }"
          />
        </div>
        <div class="skeleton-tr" v-for="t of rowArr" :key="t + 'loadSkeleton-tr'">
          <el-skeleton-item
            v-show="haveLeftNumber"
            variant="text"
            class="small"
            :style="{ margin: columns < 10 ? '0 32px' : columns < 15 ? '0 12px' : '0 6px' }"
          />
          <el-skeleton-item
            variant="text"
            v-for="t of columnArr"
            :key="t + 'loadSkeleton-td'"
            :style="{ margin: columns < 10 ? '0 32px' : '0 12px' }"
          />
        </div>
      </div>
    </template> </el-skeleton
></template>
<script>
export default {
  name: 'loadSkeleton',
  props: {
    rows: {
      type: Number,
      default: 10
    },
    columns: {
      type: Number,
      default: 5
    },
    haveLeftNumber: {
      type: Boolean,
      default: true
    }
  },
  computed: {
    rowArr() {
      const arr = []
      for (let i = 1; i <= this.rows; i++) {
        arr.push(i)
      }
      return arr
    },
    columnArr() {
      const arr = []
      for (let i = 1; i <= this.columns; i++) {
        arr.push(i)
      }
      return arr
    }
  }
}
</script>
<style>
.skeleton {
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-items: space-between;
}
.skeleton-th {
  display: flex;
  align-items: center;
  position: relative;
  width: 100%;
  height: 54px;
  box-sizing: border-box;
  background: #fafafa;
}
.skeleton-th .el-skeleton__h1 {
  height: 32px;
}
.skeleton-tr {
  display: flex;
  align-items: center;
  position: relative;
  width: 100%;
  height: 52px;
  box-sizing: border-box;
  border-bottom: 1px solid #e8e8e8;
}
.skeleton-tr * {
  height: 18px;
}
.skeleton-th .small {
  flex-grow: 0;
  flex-shrink: 0;
  flex-basis: 18px;
  width: 18px;
  height: 18px;
}
.skeleton-tr .small {
  flex-grow: 0;
  flex-shrink: 0;
  flex-basis: 18px;
  width: 178px;
}
</style>

main.js中引入公用组件

// 引入表格加载骨架屏组件
import loadSkeleton from '@/components/loadSkeleton'
Vue.component('load-skeleton', loadSkeleton)

在需要的地方使用:

<load-skeleton v-show="loading" :columns="12" :rows="5" :haveLeftNumber="false"></load-skeleton>
