数据添加、修改、watch监听和删除
数据添加
AddCategory.vue
<template> <el-dialog v-model="dialogVisible" :title="dialogTitle" width="500" :before-close="handleClose"> <el-form :model="ruleFroms" label-width="auto" style="max-width: 600px"> <el-form-item label="分类名称"> <el-input v-model="ruleFroms.name" /> </el-form-item> </el-form> <template #footer> <div class="dialog-footer"> <el-button @click="dialogVisible = false">取消</el-button> <el-button type="primary" @click="addCategory"> 提交 </el-button> </div> </template> </el-dialog> </template> <script setup> import axios from '@/api/api_config'; import { reactive, toRefs } from 'vue' import { ElMessage } from 'element-plus'; ///---------------------------------- const props = defineProps({ dialogTitle: { type: String, default: 'AddCategory' } }) const state = reactive({ dialogVisible: false, ruleFroms: { id: '', name: '' }, }) ///---------------------------------- //打开对话框 const dialogCategory = () => { state.dialogVisible = true; } //提交修改或者添加 const addCategory = () => { if (props.dialogTitle == "添加分类") { let param = { name: ruleFroms.value.name } axios.post('/category', param).then(() => { state.dialogVisible = false ElMessage.success('添加成功') }) } } //解构 const { dialogVisible, ruleFroms } = toRefs(state) //主动暴露给父组件,编译器的宏命令,不需要引入 defineExpose({ dialogCategory }) </script>
数据修改,watch监听
