vue.js+Element 增删改查
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
首先安装相关js以及css
import 'element-ui/lib/theme-default/index.css'
import Vue from 'vue'
import $ from 'jquery'
import vueResource from 'vue-resource'
import ElementUI from 'element-ui'
window.$ = $;
Vue.use(ElementUI);
Vue.use(vueResource);下面先说一下html文件
<div id="user">
<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>
<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"

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>
<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>
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 删除我设置的是单条删除以及多条删除
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
<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>
<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='';
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;
});
},
// 创建用户
createUser() {
// 主动校验
this.$refs.create.validate((valid) => {
if (valid) {
this.create.id=getuuid();
this.createLoading=true;
var resource = this.$resource(this.url);
resource.save(this.create)
.then((response) => {
this.$message.success('创建用户成功！');
this.dialogCreateVisible=false;
this.createLoading=false;
this.reset();
this.getUsers();
})
.catch((response) => {
var data=response.data;
if(data instanceof Array){
this.$message.error(data[0]["message"]);
}
else if(data instanceof Object){
this.$message.error(data["message"]);
}
this.createLoading=false;
});
}
else {
//this.$message.error('存在输入校验错误!');
return false;
}
});
},
// 更新用户资料
updateUser() {
this.$refs.update.validate((valid) => {
if (valid) {
this.updateLoading=true;
var actions = {
update: {method: 'patch'}
}
var resource = this.$resource(this.url,{},actions);
resource.update({"ids":this.currentId},this.update)
.then((response) => {
this.$message.success('修改用户资料成功！');
this.dialogUpdateVisible=false;
this.updateLoading=false;
//this.reset();
this.getUsers();
})
.catch((response) => {
var data=response.data;
console.log(data);
if(data instanceof Array){
this.$message.error(data[0]["message"]);
}
else if(data instanceof Object){
this.$message.error(data["message"]);
}
this.updateLoading=false;
});
}
else {
//this.$message.error('存在输入校验错误!');
return false;
}
});
},
// 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) => {
this.$message.success('删除了' + this.selected.length + '个用户!');
this.getUsers();
})
.catch((response) => {
this.$message.error('删除失败!');
});
})
.catch(() => {
this.$Message('已取消操作!');
});
}
}这就是整个增删改查的过程
