安装依赖

npm install @element-plus/icons-vue

全局注册

main.ts代码如下

import { createApp } from "vue";
import App from "./App.vue";
import "element-plus/lib/theme-chalk/el-message.css";

import * as ElIcons from "@element-plus/icons";

const app = createApp(App);
for (const name in ElIcons) {
  app.component(name, (ElIcons as any)[name]);
}

app.mount("#app");

代码中使用

1.结合按钮使用

<el-button type="primary" icon="Edit" >编辑</el-button>
<el-button
  size="mini"
  type="primary"
  class="inline-block"
  icon="More"
  title="详情"
  @click="handleDetail(row.id)"
/>

2.结合el-icon使用

  <el-icon>
    <delete />
  </el-icon>

3.使用el-menu的文件

<template>
  <div>
    <el-scrollbar wrap-class="scrollbar-wrapper">
      <el-menu
        router
        :default-active="activeMenu"
        @open="handleOpen"
        @close="handleClose"
      >
        <template v-for="route in menuList" :key="route.path">
          <el-menu-item v-if="!route.children" :index="route.path">
            <el-icon>
              <component :is="route.meta.icon" />
            </el-icon>
            <span>{{ route.meta.title }}</span>
          </el-menu-item>
          <el-sub-menu v-else :index="route.path">
            <template #title>
              <el-icon>
                <component :is="route.meta.icon" />
              </el-icon>
              <span>{{ route.meta.title }}</span>
            </template>
            <el-menu-item
              v-for="subRoute in route.children"
              :key="subRoute.path"
              :index="subRoute.path"
            >
              <el-icon>
                <component :is="subRoute.meta.icon" />
              </el-icon>
              <span>{{ subRoute.meta.title }}</span>
            </el-menu-item>
          </el-sub-menu>
        </template>
      </el-menu>
    </el-scrollbar>
  </div>
</template>

<script lang="ts">
import { defineComponent, computed } from 'vue'
import { useRoute } from 'vue-router'
import { routes } from '@/router/index'

export default defineComponent({
  setup() {
    const route = useRoute()
    const activeMenu = computed(() => {
      const { meta, path } = route
      if (meta.activeMenu) {
        return meta.activeMenu
      }
      return path
    })
    const menuList = computed(
      () => (routes as any).find((item: any) => item.path === '/').children
    )
    return { activeMenu, menuList }
  },
})
</script>

4. 表单中 prefix ，suffix 前置，后置图标使用

<el-form-item class="input-button">
  <div class="input">
    <el-input prefix-icon="Lock" suffix-icon="View" type="password" v-model="loginForm.password"
      autocomplete="off" placeholder="请输入密码">
      <template #prefix>
        <lock></lock>
      </template>
      <template #suffix>
        <View></View>
      </template>
    </el-input>
  </div>
</el-form-item>

局部引入，需要哪个图标引入哪个，因为element-plus中每个图标都是一个组件来的。如：

import { User, Lock, View } from "@element-plus/icons-vue";
