1.实现效果：

 2.实现代码：

1.封装svg-icon组件

在src/components 文件夹下面新建SvgIcon/index.vue文件

<template>
  <div v-if="isExternal" :style="styleExternalIcon" class="svg-external-icon svg-icon" v-on="$listeners" />
  <svg v-else :class="svgClass" aria-hidden="true" v-on="$listeners">
    <use :xlink:href="iconName" />
  </svg>
</template>

<script>
// doc: https://panjiachen.github.io/vue-element-admin-site/feature/component/svg-icon.html#usage
import { isExternal } from '@/utils/validate'

export default {
  name: 'SvgIcon',
  props: {
    iconClass: {
      type: String,
      required: true
    },
    className: {
      type: String,
      default: ''
    }
  },
  computed: {
    isExternal() {
      return isExternal(this.iconClass)
    },
    iconName() {
      return `#icon-${this.iconClass}`
    },
    svgClass() {
      if (this.className) {
        return 'svg-icon ' + this.className
      } else {
        return 'svg-icon'
      }
    },
    styleExternalIcon() {
      return {
        mask: `url(${this.iconClass}) no-repeat 50% 50%`,
        '-webkit-mask': `url(${this.iconClass}) no-repeat 50% 50%`
      }
    }
  }
}
</script>

<style scoped>
.svg-icon {
  width: 1em;
  height: 1em;
  vertical-align: -0.15em;
  fill: currentColor;
  overflow: hidden;
}

.svg-external-icon {
  background-color: currentColor;
  mask-size: cover!important;
  display: inline-block;
}
</style>

2.新建存放svg小图标的文件

 3.再icons文件夹下面新建index.js文件

import Vue from 'vue'
import SvgIcon from '@/components/SvgIcon'// 第一步新建的svg组件路径

// register globally
Vue.component('svg-icon', SvgIcon)

const req = require.context('./svg', false, /\.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)
requireAll(req)

4.在mian.js中引入第三步创建的index.js文件

import '@/icons' // icon

5.新建svg-icon的页面和选择小图标的弹框页面

index.vue

<template>
  <div class="icons-container">

    <el-form :inline="true" :model="formInline">
      <el-row>
        <el-form-item label="图标名称">
          <el-input v-model="formInline.iconName" placeholder="图标名称">
            <svg-icon slot="prefix" :icon-class="formInline.iconName"></svg-icon>
            <el-button slot="append" type="primary" @click="chooseIcon" icon="el-icon-plus">选择图标</el-button>
          </el-input>
        </el-form-item>
      </el-row>
    </el-form>
    <!--  选择图标界面  -->
    <icon_choose ref="iconChoose" @closeIconDialog="close_dialog"></icon_choose>
  </div>
</template>

<script>
  import icon_choose from './icon_choose'

  export default {
    name: "index.vue",
    components: {icon_choose},

    data() {
      return {
        formInline: {
          iconName: ''
        }

      }
    },
    methods: {
      // 选择图标
      chooseIcon() {
        this.$refs.iconChoose.open()
      },
      close_dialog(data) {
        if (data.length === 1) {
          if (data.name !== null && data.name !== undefined) {
            return null
          } else {
            this.formInline.iconName = data
          }
        } else {
          this.formInline.iconName = data
        }
      }

    }
  }
</script>

<style lang="scss" scoped>
  .icons-container {
    margin: 10px 20px 0;
    overflow: hidden;

    .tabPane {
      height: 600px;
      overflow-y: auto;
      overflow-x: hidden;
    }

    .grid {
      position: relative;
      display: grid;
      grid-template-columns: repeat(auto-fill, minmax(120px, 1fr));
    }

    .icon-item {
      margin: 20px;
      height: 85px;
      text-align: center;
      width: 100px;
      float: left;
      font-size: 30px;
      color: #24292e;
      cursor: pointer;
    }

    span {
      display: block;
      font-size: 16px;
      margin-top: 10px;
    }

    .disabled {
      pointer-events: none;
    }
  }

  .svg-icon {
    height: 2.5em;
  }
</style>

选择小图标的弹框 icon_choose.vue

<template>

  <el-dialog :title="titleName" :visible.sync="iconDialogVisible" custom-class="custom_dialog" :close-on-click-modal="false"
             :modal-append-to-body="false" width="40%"  :before-close="onClose" append-to-body>

    <div class="icons-container">
      <el-tabs type="border-card">
        <el-tab-pane label="彩色图标" class="tabPane">
          <div class="grid">
            <div v-for="item of svgIcons" :key="item" @click="handleClipboard(generateIconCode(item),$event)">
              <el-tooltip placement="top">
                <div slot="content">
                  {{ generateIconCode(item) }}
                </div>
                <div class="icon-item">

            <div v-for="item of elementIcons" :key="item" @click="handleClipboard(generateElementIconCode(item),$event)">

                  <i :class="'el-icon-' + item"/>
                  <span>{{ item }}</span>
