新项目使用的是vue.js 后来发现饿了吗前端编写的一套框架Element (http://element.eleme.io/#/zh-CN)来配合vue.js进行样式填充
之前用过angularjs 用到后来 发现越来越难学 于是就决定用vue.js
下面就介绍一下vue.js应用在表格里的增删改查
首先引入一下element的css以及js
- <link rel="stylesheet" type="text/css" href="plugins/element-ui/theme-default/index.css">
- <script src="plugins/element-ui/index.js"></script>
然后引入需要用到的vue相关的js文件
- <script src="plugins/vue/vue.js"></script>
- <script src="plugins/vue/vue-resource.js"></script>
- <script src="plugins/vue/vue-moment.min.js"></script>
- <script src="js/jquery.min.js"></script>
下面先说一下html文件
- <div id="user">
- <!-- 操作 -->
- <ul class="btn-edit fr">
- <li >
- <el-button type="primary" @click="dialogCreateVisible = true">添加用户</el-button>
- <el-button type="primary" icon="delete" :disabled="selected.length==0" @click="removeUsers()" >删除</el-button>
- <el-button type="primary" icon="edit" :disabled="selected.length==0" >停用</el-button>
- <el-button type="primary" icon="edit" :disabled="selected.length==0" >激活</el-button>
- </li>
- </ul>
- <!-- 用户列表-->
- <el-table :data="users"
- stripe
- v-loading="loading"
- element-loading-text="拼命加载中..."
- style="width: 100%"
- height="443"
- @sort-change="tableSortChange"
- @selection-change="tableSelectionChange">
- <el-table-column type="selection"
- width="60">
- </el-table-column>
- <el-table-column sortable="custom" prop="username"
- label="用户名"
- width="120">
- </el-table-column>
- <el-table-column prop="name"
- label="姓名"
- width="120">
- </el-table-column>
- <el-table-column prop="phone"
- label="手机"
- >
- </el-table-column>
- <el-table-column prop="email"
- label="邮箱">
- </el-table-column>
- <el-table-column prop="create_time" sortable="custom" inline-template
- label="注册日期"
- width="260">
- <div>{{ row.create_time | moment('YYYY年MM月DD日 HH:mm:ss')}}</div>
- </el-table-column>
- <el-table-column inline-template
- label="操作"
- width="250">
- <span>
- <el-button type="primary" size="mini" @click="removeUser(row)">删除</el-button>
- <el-button type="primary" size="mini" @click="setCurrent(row)">编辑</el-button>
- </span>
- </el-table-column>
- </el-table>
- <!--分页begin-->
- <el-pagination class="tc mg"
- :current-page="filter.page"
- :page-sizes="[10, 20, 50, 100]"
- :page-size="filter.per_page"
- layout="total, sizes, prev, pager, next, jumper"
- :total="total_rows"
- @size-change="pageSizeChange"
- @current-change="pageCurrentChange">
- </el-pagination>
- <!--分页end-->
- </div>
这一段是element的表单以及编辑还有分页样式 可以直接复制进来 其中添加了一些click操作 后面需要用到
然后我们就开始引入js
了解过vuejs的应该知道这样的结构 data里面填写我们获取的数据 一些规则 定义一些变量
在methods进行我们的操作
- vm = new Vue({
- el: '#user',
- data:{},
- methods:{}
- })
首先 我们先从读取数据开始
放入你的url
users是表格绑定的数组 也是存放从后台获取的数据
将需要显示的数据放在filter中
- vm = new Vue({
- el: '#user',
- // 数据模型
- data: function() {
- return {
- url: 'url',
- users: [],
- filter: {
- per_page: 10, // 页大小
- page: 1, // 当前页
- name:'',
- username:'',
- phone:'',
- is_active:'',
- sorts:''
- },
- total_rows: 0,
- loading: true,
- };
- },
- methods:{}
- })
接下来我们添加methods
pageSizeChange() 以及 pageCurrentChange()是用于分页的函数
在query() 是用于搜索的项目
getUsers() 就是用于获取数据
- methods: {
- pageSizeChange(val) {
- this.filter.per_page = val;
- this.getUsers();
- },
- pageCurrentChange(val) {
- this.filter.page = val;
- this.getUsers();
- },
- query(){
- this.filter.name='';
- this.filter.username='';
- this.filter.phone='';
- this.filter[this.select]=this.keywords;
- this.getUsers();
- },
- // 获取用户列表
- getUsers() {
- this.loading = true;
-
- var resource = this.$resource(this.url);
- resource.query(this.filter)
- .then((response) => {
- this.users = response.data.datas;
- this.total_rows = response.data.total_rows;
- this.loading = false;
- })
- .catch((response)=> {
- this.$message.error('错了哦,这是一条错误消息');
- this.loading = false;
- });
-
- },
- }
读取完数据之后 我们可以看见数据是按照每页十条显示 是上面我们默认设置的
下面进行删除操作 删除我设置的是单挑删除以及多条删除
因为删除需要选中 所以我们需要加入选中的变量
- vm = new Vue({
- el: '#user',
- // 数据模型
- data: function() {
-
- return {
- url: 'http://172.10.0.201/api/v1/accounts',
- users: [
- ],
- filter: {
- per_page: 10, // 页大小
- page: 1, // 当前页
- name:'',
- username:'',
- phone:'',
- is_active:'',
- sorts:''
- },
- total_rows: 0,
- loading: true,
- selected: [], //已选择项
- };
- },
然后在methods也要加入选中的函数
- tableSelectionChange(val) {
- console.log(val);
- this.selected = val;
- },
// 删除单个用户
- removeUser(user) {
- this.$confirm('此操作将永久删除用户 ' + user.username + ', 是否继续?', '提示', { type: 'warning' })
- .then(() => { // 向请求服务端删除
- var resource = this.$resource(this.url + "{/id}");
- resource.delete({ id: user.id })
- .then((response) => {
- this.$message.success('成功删除了用户' + user.username + '!'); this.getUsers(); })
- .catch((response) => {
- this.$message.error('删除失败!');
- });
- }) .catch(() => {
- this.$message.info('已取消操作!');
- });
- },
- //删除多个用户
- removeUsers() {
- this.$confirm('此操作将永久删除 ' + this.selected.length + ' 个用户, 是否继续?', '提示', { type: 'warning' })
- .then(() => {
- console.log(this.selected);
- var ids = []; //提取选中项的id
- $.each(this.selected,(i, user)=> { ids.push(user.id); }); // 向请求服务端删除var resource = this.$resource(this.url);
- resource.remove({ids: ids.join(",")
- }) .then((response) => {
- .catch((response) => {
- this.$message.error('删除失败!');
- });
- })
- .catch(() => {
- });
- }
接下来就进行到编辑和添加
由于删除和编辑需要加入表单
- <!-- 创建用户 begin-->
- <el-dialog title="创建用户" v-model="dialogCreateVisible" :close-on-click-modal="false" :close-on-press-escape="false" @close="reset" >
- <el-form id="#create" :model="create" :rules="rules" ref="create" label-width="100px">
- <el-form-item label="用户名" prop="username">
- <el-input v-model="create.username"></el-input>
- </el-form-item>
- <el-form-item label="姓名" prop="name">
- <el-input v-model="create.name"></el-input>
- </el-form-item>
- <el-form-item label="密码" prop="password">
- <el-input v-model="create.password" type="password" auto-complete="off"></el-input>
- </el-form-item>
- <el-form-item label="确认密码" prop="checkpass">
- <el-input v-model="create.checkpass" type="password"></el-input>
- </el-form-item>
- <el-form-item label="电话" prop="phone">
- <el-input v-model="create.phone"></el-input>
- </el-form-item>
- <el-form-item label="邮箱" prop="email">
- <el-input v-model="create.email"></el-input>
- </el-form-item>
- <el-form-item label="是否启用">
- <el-switch on-text="" off-text="" v-model="create.is_active"></el-switch>
- </el-form-item>
- </el-form>
- <div slot="footer" class="dialog-footer">
- <el-button @click="dialogCreateVisible = false">取 消</el-button>
- <el-button type="primary" :loading="createLoading" @click="createUser">确 定</el-button>
- </div>
- </el-dialog>
- <!-- 修改用户 begin-->
- <el-dialog title="修改用户信息" v-model="dialogUpdateVisible" :close-on-click-modal="false" :close-on-press-escape="false">
- <el-form id="#update" :model="update" :rules="updateRules" ref="update" label-width="100px">
- <el-form-item label="姓名" prop="name">
- <el-input v-model="update.name"></el-input>
- </el-form-item>
- <el-form-item label="电话" prop="phone">
- <el-input v-model="update.phone"></el-input>
- </el-form-item>
- <el-form-item label="邮箱" prop="email">
- <el-input v-model="update.email"></el-input>
- </el-form-item>
- <el-form-item label="是否启用">
- <el-switch on-text="" off-text="" v-model="update.is_active"></el-switch>
- </el-form-item>
- </el-form>
- <div slot="footer" class="dialog-footer">
- <el-button @click="dialogUpdateVisible = false">取 消</el-button>
- <el-button type="primary" :loading="updateLoading" @click="updateUser">确 定</el-button>
- </div>
- </el-dialog>
因为有表单 所以我们需要加入表单验证
以及添加和编辑弹出的状态
- vm = new Vue({
- el: '#user',
- // 数据模型
- data: function() {
-
- var validatePass = (rule, value, callback) => {
- if (value === '') {
- callback(new Error('请再次输入密码'));
- } else if (value !== this.create.password) {
- callback(new Error('两次输入密码不一致!'));
- } else {
- callback();
- }
- };
-
- return {
- url: 'http://172.10.0.201/api/v1/accounts',
- users: [
- ],
- create: {
- id: '',
- username: '',
- name: '',
- password: '',
- checkpass: '',
- phone: '',
- email: '',
- is_active: true
- },
- currentId:'',
- update:{
- name: '',
- phone: '',
- email: '',
- is_active: true
- },
- rules: {
- name: [
- { required: true, message: '请输入姓名', trigger: 'blur' },
- { min: 3, max: 15, message: '长度在 3 到 15 个字符'}
- ],
- username: [
- { required: true, message: '请输入用户名', trigger: 'blur' },
- { min: 3, max: 25, message: '长度在 3 到 25 个字符'},
- { pattern:/^[A-Za-z0-9]+$/, message: '用户名只能为字母和数字'}
- ],
- password: [
- { required: true, message: '请输入密码', trigger: 'blur' },
- { min: 6, max: 25, message: '长度在 6 到 25 个字符'}
- ],
- checkpass: [
- { required: true, message: '请再次输入密码', trigger: 'blur' },
- { validator: validatePass}
- ],
- email: [
- { type: 'email', message: '邮箱格式不正确'}
- ],
- phone:[
- { pattern:/^1[34578]\d{9}$/, message: '请输入中国国内的手机号码'}
- ]
- },
- updateRules: {
- name: [
- { required: true, message: '请输入姓名', trigger: 'blur' },
- { min: 3, max: 15, message: '长度在 3 到 15 个字符'}
- ],
- email: [
- { type: 'email', message: '邮箱格式不正确'}
- ],
- phone:[
- { pattern:/^1[34578]\d{9}$/, message: '请输入中国国内的手机号码'}
- ]
- },
- filter: {
- per_page: 10, // 页大小
- page: 1, // 当前页
- name:'',
- username:'',
- phone:'',
- is_active:'',
- sorts:''
- },
- total_rows: 0,
- loading: true,
- selected: [], //已选择项
- dialogCreateVisible: false, //创建对话框的显示状态
- dialogUpdateVisible: false, //编辑对话框的显示状态
- createLoading: false,
- updateLoading: false,
- };
- },
下面就加入添加和编辑的函数
- methods: {
- tableSelectionChange(val) {
- console.log(val);
- this.selected = val;
- },
- pageSizeChange(val) {
- console.log(`每页 ${val} 条`);
- this.filter.per_page = val;
- this.getUsers();
- },
- pageCurrentChange(val) {
- console.log(`当前页: ${val}`);
- this.filter.page = val;
- this.getUsers();
- },
- setCurrent(user){
- this.currentId=user.id;
- this.update.name=user.name;
- this.update.phone=user.phone;
- this.update.email=user.email;
- this.update.is_active=user.is_active;
- this.dialogUpdateVisible=true;
- },
- // 重置表单
- reset() {
- this.$refs.create.resetFields();
- },
- query(){
- this.filter.name='';
- this.filter.username='';
