媒介
前面我们已经实现了一个表格, 能够展示用户的信息, 一个分页能够执行分页获取用户信息.
到目前为止, 数据的渲染, 我们基本就做的差不多了, 接下来我们来扩展一下表格, 让其支持添加按钮, 我们在内里添加编辑按钮和删除按钮.
表格样式调整
我调整了一下表格的样式, 增加了操作列, 目前看起来是如许的:
代码内里增加了操作这一列:
操作这一列可以根据一个叫做operator的属性进行控制, 默认是true, 如果改成false, 则不表现操作列.
稍微调整一下删除按钮的样式
暴露按钮点击方法
起首是在组件中添加要暴露的方法:
- const emit = defineEmits(['edit', 'delete']);
- const onEdit = (index, item) => emit('edit', index, item) // 编辑
- const onDelete = (index, item) => emit('delete', index, item) // 删除
复制代码 接着给按钮绑定:
- <button @click.stop="onEdit(k, v)">编辑</button>
- <button class="delete" @click.stop="onDelete(k,v)">删除</button>
复制代码 在App.vue中监听编辑和删除这两个事件:
- <zdp_table1
- :columns="columns"
- :data="data"
- @edit="onEdit"
- @delete="onDelete"
- />
复制代码 再简单的实现事件的监听:
- const onEdit = (index, item) => {
- console.log("编辑", index, item)
- }
- const onDelete = (index, item) => {
- console.log("删除", index, item)
- }
复制代码 此时, 当我们点击编辑按钮的删除按钮的时间, 控制台会输出对应的内容.
此时页面结果如下:
App.vue的完备代码如下:
- <script setup>import zdp_table1 from "./zdpui/components/zdp_table1.vue";import zdp_page1 from "./zdpui/components/zdp_page1.vue";import random from "./zdpui/js/random.js";import {ref} from "vue";const columns = [ { title: "员工编号", key: "id", width: 80, align: "center" }, { title: "姓名", key: "name", width: 100, align: "center" }, { title: "年龄", key: "age", width: 100, align: "center" }]const page = ref(1);const size = ref(10);const total = ref(100);const data = ref(random.users(size.value))const onChangePage = (v) => { page.value = v const newData = random.getPageUser( page.value, size.value, ) data.value = newData.data total.value = total.value}const onEdit = (index, item) => {
- console.log("编辑", index, item)
- }
- const onDelete = (index, item) => {
- console.log("删除", index, item)
- }
- </script><template> <div> <zdp_table1
- :columns="columns"
- :data="data"
- @edit="onEdit"
- @delete="onDelete"
- />
- <zdp_page1 :page="page" :size="size" :total="total" @change="onChangePage" /> </div></template>
复制代码 删除确认
当我们点击删除的时间, 盼望能够弹出一个确认删除的对话框, 好比像下面如许.
这个我已经封装好了, 比想象中要简单的多, 完备代码如下:
- <script setup>
- import {defineEmits, defineProps} from 'vue';
- const props = defineProps({
- show: {
- type: Boolean,
- default: false
- },
- title: {
- type: String,
- default: '确认删除'
- },
- content: {
- type: String,
- default: '你确定要删除该项目吗?此操作不可逆。'
- },
- ok: {
- type: String,
- default: '确认'
- },
- cancel: {
- type: String,
- default: '取消'
- }
- });
- const emit = defineEmits(['confirm', 'close']);
- const onClose = () => emit('close')
- const onConfirm = () => emit('confirm')
- </script>
- <template>
- <div class="confirm-delete-dialog" v-if="props.show">
- <div class="dialog-overlay" @click.self="onClose"></div>
- <div class="dialog-content">
- <h2>{{ props.title }}</h2>
- <p>{{ props.content }}</p>
- <div class="dialog-buttons">
- <button @click="onConfirm">{{ props.ok }}</button>
- <button @click="onClose">{{ props.cancel }}</button>
- </div>
- </div>
- </div>
- </template>
- <style scoped>
- .confirm-delete-dialog {
- position: fixed;
- top: 0;
- left: 0;
- width: 100%;
- height: 100%;
- display: flex;
- justify-content: center;
- align-items: center;
- z-index: 1000;
- }
- .dialog-overlay {
- position: absolute;
- top: 0;
- left: 0;
- width: 100%;
- height: 100%;
- background-color: rgba(0, 0, 0, 0.5);
- }
- .dialog-content {
- background-color: #fff;
- padding: 20px;
- border-radius: 10px;
- box-shadow: 0 0 20px rgba(0, 0, 0, 0.3);
- z-index: 1001;
- text-align: center;
- }
- .dialog-content h2 {
- margin-top: 0;
- color: #009FFF;
- }
- .dialog-content p {
- margin-bottom: 20px;
- }
- .dialog-buttons button {
- padding: 10px 20px;
- margin: 0 10px;
- border: none;
- border-radius: 5px;
- cursor: pointer;
- font-weight: bold;
- color: white;
- transition: all 0.3s ease-in-out;
- }
- .dialog-buttons button:first-child {
- background: linear-gradient(45deg, #C70039, #FF5733);
- box-shadow: 0 5px 10px rgba(199, 0, 57, 0.4);
- }
- .dialog-buttons button:first-child:hover {
- transform: translateY(-3px);
- box-shadow: 0 8px 15px rgba(199, 0, 57, 0.6);
- background: linear-gradient(45deg, #FF5733, #FF8C00);
- }
- .dialog-buttons button:first-child:active {
- transform: translateY(1px);
- box-shadow: 0 3px 8px rgba(199, 0, 57, 0.8);
- background: linear-gradient(45deg, #900C3F, #C70039);
- }
- .dialog-buttons button:last-child {
- background: linear-gradient(45deg, #009FFF, #0066CC);
- box-shadow: 0 5px 10px rgba(0, 159, 255, 0.4);
- }
- .dialog-buttons button:last-child:hover {
- transform: translateY(-3px);
- box-shadow: 0 8px 15px rgba(0, 159, 255, 0.6);
- background: linear-gradient(45deg, #00BFFF, #0088EE);
- }
- .dialog-buttons button:last-child:active {
- transform: translateY(1px);
- box-shadow: 0 3px 10px rgba(0, 159, 255, 0.8);
- background: linear-gradient(45deg, #0077DD, #0055AA);
- }
- </style>
复制代码 在App.vue中的利用代码如下:
编辑弹窗
结果预览:
此时App.vue代码如下:
- <script setup>import zdp_table1 from "./zdpui/components/zdp_table1.vue";import zdp_page1 from "./zdpui/components/zdp_page1.vue";import random from "./zdpui/js/random.js";import {ref} from "vue";import zdp_confirm1 from "./zdpui/components/zdp_confirm1.vue";import zdp_modal1 from "./zdpui/components/zdp_modal1.vue";import Zdp_input1 from "./zdpui/components/zdp_input1.vue";const columns = [ { title: "员工编号", key: "id", width: 80, align: "center" }, { title: "姓名", key: "name", width: 100, align: "center" }, { title: "年龄", key: "age", width: 100, align: "center" }]const page = ref(1);const size = ref(10);const total = ref(100);const data = ref(random.users(size.value))const onChangePage = (v) => { page.value = v const newData = random.getPageUser( page.value, size.value, ) data.value = newData.data total.value = total.value}const onEdit = (index, item) => { console.log("编辑", index, item) showEditDialog.value = true;}const onDelete = (index, item) => { console.log("删除", index, item) showDeleteDialog.value = true;}const showDeleteDialog = ref(false);const onConfirmDelete = () => { console.log("确认删除"); showDeleteDialog.value = false;};const onCloseDeleteDialog = () => { console.log("取消删除"); showDeleteDialog.value = false;};const showEditDialog = ref(false);const formData = ref({name: "张三", age: 23});const handleEditConfirm = (userData) => { console.log('确认编辑操作,用户数据:', userData); // 在这里添加编辑逻辑,如发送编辑请求等};const handleCloseDialog = () => { showEditDialog.value = false;};</script><template> <div> <zdp_table1
- :columns="columns"
- :data="data"
- @edit="onEdit"
- @delete="onDelete"
- />
- <zdp_page1 :page="page" :size="size" :total="total" @change="onChangePage" /> <zdp_confirm1 :show="showDeleteDialog" @confirm="onConfirmDelete" @close="onCloseDeleteDialog" /> <zdp_modal1 :show="showEditDialog" @confirm="handleEditConfirm" @close="handleCloseDialog" > <zdp_input1 label="姓名" v-model="formData.name" placeholder="请输入姓名" /> <zdp_input1 label="年龄" v-model="formData.age" placeholder="请输入年龄" /> </zdp_modal1> </div></template>
复制代码 继续封装按钮
到这一步的时间, 发现按钮有很多地方都是一样的, 重复的, 以是决定对按钮进行封装.
按钮组件的内容如下:
- <script setup>
- import {defineProps, defineEmits} from 'vue';
- const props = defineProps({
- text: {
- type: String,
- default: '按钮',
- },
- type: {
- type: String,
- // primary,danger
- default: 'primary',
- }
- })
- const emits = defineEmits(['click'])
- </script>
- <template>
- <button
- @click="emits('click')"
- :class="props.type"
- >
- {{ props.text }}
- </button>
- </template>
- <style scoped>
- button {
- padding: 10px 20px;
- margin: 0 10px;
- border: none;
- border-radius: 5px;
- cursor: pointer;
- font-weight: bold;
- color: white;
- transition: all 0.3s ease-in-out;
- }
- button.danger {
- background: linear-gradient(45deg, #C70039, #FF5733);
- box-shadow: 0 5px 10px rgba(199, 0, 57, 0.4);
- }
- button.danger:hover {
- transform: translateY(-3px);
- box-shadow: 0 8px 15px rgba(199, 0, 57, 0.6);
- background: linear-gradient(45deg, #FF5733, #FF8C00);
- }
- button.danger:active {
- transform: translateY(1px);
- box-shadow: 0 3px 8px rgba(199, 0, 57, 0.8);
- background: linear-gradient(45deg, #900C3F, #C70039);
- }
- button.primary {
- background: linear-gradient(45deg, #009FFF, #0066CC);
- box-shadow: 0 5px 10px rgba(0, 159, 255, 0.4);
- }
- button.primary:hover {
- transform: translateY(-3px);
- box-shadow: 0 8px 15px rgba(0, 159, 255, 0.6);
- background: linear-gradient(45deg, #00BFFF, #0088EE);
- }
- button.primary:active {
- transform: translateY(1px);
- box-shadow: 0 3px 10px rgba(0, 159, 255, 0.8);
- background: linear-gradient(45deg, #0077DD, #0055AA);
- }
- </style>
复制代码 利用方法如下:
- <zdp_button1/>
- <zdp_button1 type="danger"/>
复制代码 在界面中的表现结果如下:

总结
现在, 我们已经有了自己的按钮组件, 确认框组件, 编辑表单组件, 组件越来越多了.
不外这个时间, 组件之间的拆分, 组合也变得越来越复杂了, 好比这个编辑表单组件, 就因为有输入框组件, 按钮组件, 确认框组件等多个组件的组合, 显得很复杂, 样式调整稍微贫苦了一点点.
不外一切都还比较顺利!!!
继续做吧!!!
