一、实现效果
效果一：
效果二：
效果一的这个是把全部的icon图标都让它显示出来，让我们自己选择说选图标
二、效果一实现步骤
2.1. 全局注册 icon 组件
// main.ts import App from './App.vue'; import { createApp } from 'vue'; import * as ElementPlusIconsVue from '@element-plus/icons-vue' const app = createApp(App); // 全局挂载和注册 element-plus 的所有 icon app.config.globalProperties.$icons = [] for (const [key, component] of Object.entries(ElementPlusIconsVue)) { app.config.globalProperties.$icons.push(key) app.component(key, component) } app.mount('#app');
2.2. 组件实现
<script setup lang="ts"> import { ComponentInternalInstance, defineEmits, defineProps, getCurrentInstance } from 'vue' const { appContext: {app: { config: { globalProperties } } } } = getCurrentInstance() as ComponentInternalInstance interface Props { modelValue: string } const props = defineProps<Props>() const emits = defineEmits(['update:modelValue']) </script> <template> <el-popover trigger="focus" :width="256"> <template #reference> <el-button :icon="modelValue">{{ modelValue }}</el-button> </template> <div class="el-icon-picker"> <component v-for="icon in globalProperties.$icons" :key="icon" :class="[icon, 'icon', { 'icon-active': icon == modelValue }]" :is="icon" @click="emits('update:modelValue', icon)"> </component> </div> </el-popover> </template> <style scoped> .el-icon-picker { height: 256px; overflow-y: scroll; display: flex; justify-content: space-around; flex-wrap: wrap; } .icon { display: inline-block; width: 24px; height: 24px; color: var(--el-text-color-regular); font-size: 20px; border-radius: 4px; cursor: pointer; text-align: center; line-height: 45px; margin: 5px; } .icon:hover { color: var(--el-color-primary); } .icon-active { color: var(--el-color-primary); } </style>
2.3. 使用
<script setup lang="ts"> import { ref } from 'vue'; import ElIconPicker from './components/el-icon-picker.vue'; const icon = ref<string>(''); </script> <template> <el-form> <el-form-item label="图标"> <ElIconPicker v-model="icon"></ElIconPicker> </el-form-item> </el-form> </template>
效果二的这个是渲染后端返回的icon图标
三、效果二实现步骤
3.1. 全局注册 icon 组件
// main.ts import App from './App.vue'; import { createApp } from 'vue'; import * as ElementPlusIconsVue from '@element-plus/icons-vue' const app = createApp(App); // 全局挂载和注册 element-plus 的所有 icon app.config.globalProperties.$icons = [] for (const [key, component] of Object.entries(ElementPlusIconsVue)) { app.config.globalProperties.$icons.push(key) app.component(key, component) } app.mount('#app');
3.2. 组件实现
<template> <el-popover trigger="focus" :width="256"> <template #reference> <el-button style="width: 100px" :icon="props.modelValue">{{ modelValue }}</el-button> </template> <div class="el-icon-picker"> <component v-for="icon in props.fatherIcon" :key="icon.value" :class="[icon.value, 'icon', { 'icon-active': icon.value == props.modelValue }]" :is="icon.value" @click="emits('update:modelValue', icon.value)"> </component> </div> </el-popover> </template> <script lang="ts" setup> interface Props { modelValue: string, fatherIcon: any[] } const props = defineProps<Props>(); console.log(props) const emits = defineEmits(['update:modelValue']); </script> <style scoped> .el-icon-picker { min-height: 20px; overflow-y: scroll; display: flex; flex-wrap: wrap; } .icon { display: inline-block; width: 24px; height: 24px; color: var(--el-text-color-regular); font-size: 20px; border-radius: 4px; cursor: pointer; text-align: center; line-height: 45px; margin: 5px; } .icon:hover { color: var(--el-color-primary); } .icon-active { color: var(--el-color-primary); } </style>
3.3. 使用
<script setup lang="ts"> import { ref } from 'vue'; import ElIconPicker from './components/el-icon-picker.vue'; const icon = ref<string>(''); </script> <template> <el-form> <el-form-item label="图标"> <ElIconPicker v-model="ic" :fatherIcon="icon"></ElIconPicker> </el-form-item> </el-form> </template>
