其实很简单

<!--封装部门选择的插件 需要的组件 子组件-->
<template><el-select  :value="value" placeholder="请选择所属部门" @change="handleChange"><el-optionv-for="department in departments":key="department.value":label="department.label":value="department.value"></el-option></el-select>
</template><script>
import { getAction } from "@/api";
export default {name: "SelectForm",/*用于和父组件通信*/props: {value: { type: String, require: true }},model: {event: "change",prop: "value"},data() {return {/*存储部门的数据*/departments: []};},created() {/*请求方法*/this.load();},methods: {load() {/*请求接口的方法*/getAction("/department/list").then(res => {this.departments = res.data;});},/*方法调用*/handleChange(val) {this.$emit("change", val);}}
};
</script><style scoped></style>

该组件封装我认为是比较失败的 这是初期所做 想想这就是成长吧
