vue3+element-plus icons图标选择组件封装

一、最终效果

在这里插入图片描述

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

参数	说明	类型	默认值
v-model	绑定值	string	-
prefixIcon	输入框前缀icon	string	Search
isShowSearch	是否显示搜索图标	Boolean	true
isShowIcon	是否显示选中后的图标	Boolean	true
selectBind	Attributes	selectBind	`"prefix-icon": props.prefixIcon, placeholder: "请选择图标",dialogTitle:'请选择图标',clearable: true,width: "50%"`

3、events

事件名	说明	返回值
select	选择完图标	返回选中的图标name

三、源码
