vue3+element-plus icons图标选择组件封装

一、最终效果

二、参数配置

1、代码示例

<t-select-icon v-model="selectVlaue" />

2、配置参数（Attributes）继承 el-input Attributes

3、events

三、源码

<template><div class="t_select_icon"><el-inputref="inputRef"v-model="valueIcon"v-bind="attrs"@clear="clearIcon"@click="() => {;(dialogVisible = true), (inputValue = '')}"><template #append v-if="isShowIcon"><el-button :icon="customIcons[modelValue]" /></template></el-input><el-dialog v-model="dialogVisible" :title="attrs.dialogTitle" draggable :width="attrs.width"><el-inputv-model="inputValue"v-if="isShowSearch":placeholder="attrs.searchPlaceholder"clearable:prefix-icon="Icons.Search"/><el-scrollbar v-if="Object.keys(iconsList).length"><div class="icon-list"><divv-for="item in iconsList":key="item"class="icon-item":class="{ 'icon-active': item.name == valueIcon }"@click="selectIcon(item)"><component :is="item"></component><span>{{ item.name }}</span></div></div></el-scrollbar><el-empty :description="attrs.emptyDescription" v-else /></el-dialog></div>
