一.实现CRUD
配置路由接口，用于向后端请求数据
'BOOK_Add': '/book/addBook', //绑定书籍
'BOOK_UPD': '/book/editBook', //绑定书籍
'BOOK_DEL': '/book/delBook', //绑定书籍前端编写以及弹出层

<el-button type="primary" @click="dosub">确定</el-button>
</div>
</el-dialog>
</div>
</template>注意
注1：隐藏显示设置，通过Vue实例对象中的dialogFormVisible="true|false"来控制dialog显示隐藏
:visible.sync="dialogFormVisible"
注2：通过close或closed事件，在关闭dialog弹出框时清空form表单数据和验证信息；
@close="dialogClose"
增加删除修改功能，以及表单验证的实现
