1 VueJS 概述与快速入门
1.1 VueJS介绍
Vue.js是一个构建数据驱动的 web 界面的渐进式框架。Vue.js 的目标是通过尽可能简单的 API 实现响应的数据绑
定和组合的视图组件。它不仅易于上手,还便于与第三方库或既有项目整合。
官网:https://cn.vuejs.org/
1.2 MVVM模式
MVVM是Model-View-ViewModel的简写。它本质上就是MVC 的改进版。MVVM 就是将其中的View 的状态和行为
抽象化,让我们将视图 UI 和业务逻辑分开MVVM模式和MVC模式一样,主要目的是分离视图(View)和模型(Model) Vue.js 是一个提供了 MVVM 风格的双向数据绑定的 Javascript 库,专注于View 层。它的核心是 MVVM 中的 VM,也就是 ViewModel。 ViewModel负责连接 View 和 Model,保证视图和数据的一致性,这种轻量级的架构让前端开发更加高效、便捷。如图所示:

<title>快速入门</title>
<script src="js/vuejs-2.5.16.js"></script>

<body>
<div id="app">
<!--vue的插值表达式,把date中定义的数据显示到此处-->
{{message}}
</div>
</body>
<script>
// view model
// 创建vue对象
new Vue({
el:'#app', // 表示当前vue对象接管id为app区域
data:{
message:'hello vue' // 注意不要写分号结尾
}
});
</script>
</html>
如图所示:

通过浏览器访问:http://localhost:8080/demo1.html。如图所示:
1.4 插值表达式
数据绑定最常见的形式就是使用“Mustache”语法 (双大括号) 的文本插值,Mustache 标签将会被替代为对应数据对
象上属性的值。无论何时,绑定的数据对象上属性发生了改变,插值处的内容都会更新。
Vue.js 都提供了完全的 JavaScript 表达式支持。
{{ number + 1 }}
{{ ok ? 'YES' : 'NO' }}
这些表达式会在所属 Vue 实例的数据作用域下作为 JavaScript 被解析。有个限制就是,每个绑定都只能包含单个
表达式,所以下面的例子都不会生效。
<!-- 这是语句,不是表达式 -->
{{ var a = 1 }}
<!-- 流控制也不会生效,请使用三元表达式 -->
{{ if (ok) { return message } }}
演示的代码如下:
<!DOCTYPE html>

<!--vue的插值表达式,把date中定义的数据显示到此处-->
{{message}}
<!--三元运算符-->
{{fasle ? "ok":"no"}}

<!--插值表达式不支持-->
<!--{{ var a = 1;}}
{{if(a = 10(){} }}-->

如图所示:
2 VueJS 常用系统指令
2.1 v-on
可以用 v-on 指令监听 DOM 事件,并在触发时运行一些 JavaScript代码。
2.1.1 v-on:click
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:click</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
{{message}}
<button v-on:click="fun1('good')">点击改变</button>
</div>
</body>
<script>
// view model
new Vue({
el:"#app", // 表示当前vue对象接管了div区域
data:{
message:'hello vue' // /注意不要写分号结尾
},
methods:{
fun1:function (msg) {
alert("hello");
this.message = msg;
}
}
});
</script>
</html>
如图所示:
2.1.2 v-on:keydown
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:keydown</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
Vue:<input type="text" v-on:keydown="fun($event)">
<hr/>
传统JS:<input type="text" onkeydown="showKeyCode()"/>
</div>
</body>
<script>
// view model
new Vue({
el:"#app",
methods:{
/* $event 它是vue中的事件对象 和我们传统js的event对象是一样的 */
fun:function(event){
var keyCode = event.keyCode;
if(keyCode < 48 || keyCode > 57){
//不让键盘的按键起作用
event.preventDefault();
}
}
}
});
// 传统js的键盘按下事件
function showKeyCode(){
// event对象和我们的document对象以及window对象是一样的,可以不用定义直接使用
var keyCode = event.keyCode;
if(keyCode < 48 || keyCode > 57){
// 不让键盘的按键起作用
event.preventDefault();
}
// alert(keyCode);
// if(event.keyCode == 13){
// alert("你按的是回车");
// }
}
</script>
如图所示:
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:keydown</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<input type="text"v-on:keydown="fun2('good',$event)">
</div>
</body>
<script>
// view model
new Vue({ el:'#app', // 表示当前vue对象接管了div区域
methods:{
fun2:function(msg,event){
if(! ((event.keyCode >= 48 && event.keyCode <= 57) || event.keyCode == 8 || event.keyCode == 46)){
event.preventDefault();
}
}
}
});
</script>
</html>
如图所示:
2.1.3 v-on:mouseover
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:mouseover</title>
<style>
#div {
background-color: red;
}
</style>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<div v-on:mouseover="fun1" id="div">
<textarea v-on:mouseover="fun2($event)">这是一个文件域</textarea>
</div>
</div>
</body>
<script>
// view model
new Vue({ el:'#app', // 表示当前vue对象接管了div区域
methods:{
fun1:function(){
alert("div");
},
fun2:function(event){
alert("textarea");
event.stopPropagation(); // 阻止冒泡
}
}
});
</script>
</html>
如图所示:
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:mouseover</title>
<style>
#div {
background-color: red;
width:300px;
height:300px;
}
</style>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<div @mouseover="fun1" id="div">
<textarea @mouseover="fun2($event)">这是一个文件域</textarea>
</div>
<!--<div onmouseover="divmouseover()" id="div">
<textarea onmouseover="textareamouseover()">这是一个文件域</textarea>
</div>-->
</div>
</body>
<script>
// view model
/**
* @事件名称 就是v-on:事件名称的简写方式
* @mouseover它就等同于v-on:mouseover
*/
new Vue({
el:"#app",
methods:{
fun1:function(){
alert("鼠标悬停在div上了");
},
fun2:function(event){
alert("鼠标悬停在textarea上了");
event.stopPropagation();
}
}
});
// 传统的js方式
function divmouseover(){
alert("鼠标移动到了div上了");
}
function textareamouseover(){
alert("鼠标移动到了textarea上了");
event.stopPropagation();
}
</script>
</html>
如图所示:
2.1.4 事件修饰符
Vue.js 为 v-on 提供了事件修饰符来处理 DOM 事件细节,如:event.preventDefault() 或 event.stopPropagation()。
Vue.js通过由点(.)表示的指令后缀来调用修饰符。
.stop
prevent
capture
self
once
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:事件修饰符</title>
<style>
#div {
background-color: red;
width:300px;
height:300px;
}
</style>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<form @submit.prevent action="http://www.csdn.com" method="post" >
<input type="submit" value="提交">
</form>
<!--<form action="http://www.csdn.com" method="post" onsubmit="return checkForm()">
<input type="submit" value="提交">
</form>-->
<hr/>
<div @mouseover="fun1" id="div">
<textarea @mouseover.stop="fun2($event)">这是一个文件域</textarea>
</div>
</div>
</body>
<script>
// view model
new Vue({
el:"#app",
methods:{
fun1:function(){
alert("鼠标悬停在div上了");
},
fun2:function(event){
alert("鼠标悬停在textarea上了");
}
}
});
// 传统js方式
function checkForm(){
alert(1);
// 表单验证必须有一个明确的boolean类型返回值
// 在应用验证方法时必须加上return方法名称
return false;
}
</script>
</html>
如图所示:
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:事件修饰符</title>
<style>
#div {
background-color: red;
width:300px;
height:300px;
}
</style>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<form @submit.prevent action="http://www.csdn.cn" method="get">
<input type="submit" value="提交"/> </form>
<div @click="fun1">
<a @click.stop href="http://www.csdn.cn">csdn</a>
</div>
</div>
</body>
<script>
// view model
new Vue({
el:"#app", // 表示当前vue对象接管了div区域
methods:{
fun1:function(){
alert("鼠标悬停在div上了");
}
}
});
</script>
</html>
如图所示:
2.1.5 按键修饰符
Vue 允许为 v-on 在监听键盘事件时添加按键修饰符
全部的按键别名:
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:按键修饰符</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
Vue:<input type="text" @keydown.enter="fun1">
</div>
</body>
<script>
// view model
new Vue({
el:"#app", // 表示当前vue对象接管了div区域
methods:{
fun1:function(){
alert("按下的是回车");
}
}
});
</script>
</html>
如图所示:
<p><!-- Alt + C -->
<input @keyup.alt.67="clear">
<!-- Ctrl + Click -->
<div @click.ctrl="doSomething">Do something</div>
v-on简写方式
<!-- 完整语法 -->
<a v-on:click="doSomething">...</a>
<!-- 缩写 -->
<a @click="doSomething">...</a>
2.2 v-text与v-html
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-text与v-html</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<div v-text="message"></div>
<div v-html="message"></div>
<!--<div id="div1"></div>
<div id="div2"></div>-->
</div>
</body>
<script>
// view model
new Vue({
el:"#app",
data:{
message:"<h1>Hello Vue</h1>"
}
});
// 传统js的innerText和innerHTML
window.onload = function(){
document.getElementById("div1").innerHTML="<h1>Hello</h1>";
document.getElementById("div2").innerText="<h1>Hello</h1>";
}
</script>
</html>
如图所示:
2.3 v-bind
插值语法不能作用在 HTML 特性上,遇到这种情况应该使用 v-bind指令。
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-text与v-html</title>
<script src="js/vuejs-2.5.16.js"></script>

<font size="5" v-bind:color="ys1">CSDN</font>
<font size="5" :color="ys2">Csdn</font> <hr>
<a v-bind={href:"http://www.csdn.cn/index/"+id}>csdn</a>
</div>
</body>
<script>
// view model
new Vue({
el:"#app",
data:{
ys1:"red",
ys2:"green",
id:1
}
});
</script>
</html>
如图所示:
v-bind简写方式如下:
<!-- 完整语法 -->
<a v-bind:href="url">...</a>
<!-- 缩写 -->
<a :href="url">...</a>
2.4 v-model
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-model</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
姓名:<input type="text" id="username" v-model="user.username"><br>
密码:<input type="password" id="password" v-model="user.password"><br>
<input type="button" @click="fun" value="获取">
</div>
</body>
<script>
// view model
new Vue({
el:"#app", // 表示当前vue对象接管了div区域
data:{
user:{username:"",password:""}
},
methods:{
fun:function(){
alert(this.user.username+" "+this.user.password);
this.user.username="Adair";
this.user.password="123456";
}
}
})
</script>
</html>
如图所示:
2.5 v-for
操作array
演示的代码如下:

<head>
<meta charset="utf-8" />
<title>v-model</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<<div id="app">
<ul>
<li v-for="(item,index) in list">{{item+" "+index}}
</li>
</ul>
</div>
</body>
<script>
// view model
new Vue({
el:"#app", // 表示当前vue对象接管了div区域
data:{list:[1,2,3,4,5,6]
}
})
</script>

</tr>
<tr v-for="p in products">
<td>{{p.id}} </td>
<td>{{p.pname}} </td>
<td>{{p.price}} </td>
</tr>
</table>
</div>
</body>
<script>
// view model
new Vue({
el:"#app", // 表示当前vue对象接管了div区域
data:{
products:[{id:1,pname:"电视机",price:6000},{id:2,pname:"电冰箱",price:8000}, {id:3,pname:"电风扇",price:600}]
}
})
</script>
</html>
如图所示:
2.6 v-if与v-show
v-if是根据表达式的值来决定是否渲染元素。
v-show是根据表达式的值来切换元素的display css属性。
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-if与v-show</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<span v-if="flag">学无止路</span>
<span v-show="flag">csdn</span>
<button @click="toggle">切换</button>
</div>
</body>
<script>
// view model
new Vue({
el:"#app", // 表示当前vue对象接管了div区域
data: {
flag:false
},
methods:{
toggle:function (){
this.flag =! this.flag;
}
}
})
</script>
</html>
如图所示:
3 VueJS生命周期
每个Vue实例在被创建之前都要经过一系列的初始化过程。
vue在生命周期中有这些状态,
beforeCreate,created,beforeMount,mounted,beforeUpdate,updated,beforeDestroy,destroyed。Vue
在实例化的过程中,会调用这些生命周期的钩子,给我们提供了执行自定义逻辑的机会。那么,在这些vue钩子
中,vue实例到底执行了那些操作,我们先看下面执行的例子
演示的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>vuejs生命周期</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
{{message}}
</div>
</body>
<script>
var vm = new Vue({
el: "#app",
data: {
message: 'hello world'
},
beforeCreate: function() {
console.log(this);
showData('创建vue实例前', this);
},
created: function() {
showData('创建vue实例后', this);
},
beforeMount: function() {
showData('挂载到dom前', this);
},
mounted: function() {
showData('挂载到dom后', this);
},
beforeUpdate: function() {
showData('数据变化更新前', this);
},
updated: function() {
showData('数据变化更新后', this);
},
beforeDestroy: function() {
vm.test = "3333";
showData('vue实例销毁前', this);
},
destroyed: function() {
showData('vue实例销毁后', this);
}
});
function realDom() {
console.log('真实dom结构:' + document.getElementById('app').innerHTML);
}
function showData(process, obj) {
console.log(process);
console.log('data 数据:' + obj.message)
console.log('挂载的对象:')
console.log(obj.$el)
realDom();
console.log('------------------')
console.log('------------------')
}
// vm.message = "good...";
vm.$destroy();
</script>
</html>
如图所示:
运行的结果如图所示:
vue对象初始化过程中,会执行到beforeCreate,created,beforeMount,mounted 这几个钩子的内容
beforeCreate :数据还没有监听,没有绑定到vue对象实例,同时也没有挂载对象。
created :数据已经绑定到了对象实例,但是还没有挂载对象。
beforeMount: 模板已经编译好了,根据数据和模板已经生成了对应的元素对象,将数据对象关联到了对象的el属性,el属性是一个HTMLElement对象,也就是这个阶段,vue实例通过原生的createElement等方法来创建这个html片段,准备注入到我们vue实例指明的el属性所对应的挂载点。
mounted:将el的内容挂载到了el,相当于我们在jquery执行了(el).html(el),生成页面上真正的dom,上面我们就会发现dom的元素和我们el的元素是一致的。在此之后,我们能够用方法来获取到el元素下的dom对象,并进行各种操作当我们的data发生改变时,会调用beforeUpdate和updated方。
beforeUpdate :数据更新到dom之前,我们可以看到$el对象已经修改,但是我们页面上dom的数据还没有发生改变。
updated: dom结构会通过虚拟dom的原则,找到需要更新页面dom结构的最小路径,将改变更新到dom上面,完成更新。
beforeDestroy,destroed :实例的销毁,vue实例还是存在的,只是解绑了事件的监听还有watcher对象数据与view的绑定,即数据驱动。
4 VueJS ajax
4.1 vue-resource
vue-resource是Vue.js的插件提供了使用XMLHttpRequest或JSONP进行Web请求和处理响应的服务。 当vue更新到2.0之后,作者就宣告不再对vue-resource更新,而是推荐的axios,在这里大家了解一下vue-resource就可以。
vue-resource的github: https://github.com/pagekit/vue-resource。
4.2 axios
Axios 是一个基于 promise 的 HTTP 库,可以用在浏览器和 node.js中axios的github:https://github.com/axios/axios
4.2.1 引入axios
首先就是引入axios,如果你使用es6,只需要安装axios模块之后
import axios from 'axios';
// 安装方法
npm install axios
//或bower
install axios
当然也可以用script引入的代码如下:
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
4.2.2 get请求
演示的代码如下:
// 通过给定的ID来发送请求
axios.get('/user?ID=12345')
.then(function(response){
console.log(response);
})
.catch(function(err){
console.log(err);
});
// 以上请求也可以通过这种方式来发送
axios.get('/user',{
params:{
ID:12345
}
})
.then(function(response){
console.log(response);
})
.catch(function(err){
console.log(err);
});
4.2.3 post请求
演示的代码如下:
axios.post('/user',{
firstName:'Fred',
lastName:'Flintstone'
})
.then(function(res){
console.log(res);
})
.catch(function(err){
console.log(err);
});
为方便起见,为所有支持的请求方法提供了别名的代码如下:
axios.request(config)
axios.get(url[, config])
axios.delete(url[, config])
axios.head(url[, config])
axios.post(url[, data[, config]])
axios.put(url[, data[, config]])
axios.patch(url[, data[, config]])
5 综合案例
5.1 案例需求
完成用户的查询与修改操作
5.2 数据库设计与表结构
演示的代码如下:
CREATE DATABASE vuejsdemo;
USE vuejsdemo;
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`age` int(11) DEFAULT NULL,
`username` varchar(20) DEFAULT NULL,
`PASSWORD` varchar(50) DEFAULT NULL,
`email` varchar(50) DEFAULT NULL,
`sex` varchar(20) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;
INSERT INTO `user` VALUES ('1', '25', 'Adair', '123', '1578533828@qq.com', '男 ');
INSERT INTO `user` VALUES ('2', '31', 'Mars', '123', '1578533828@qq.com', '女');
INSERT INTO `user` VALUES ('3', '17', 'Litao', '213', '1578533828@qq.com', '女');
INSERT INTO `user` VALUES ('4', '40', '高管', '213', '1578533828@qq.com', 'female');
INSERT INTO `user` VALUES ('5', '28', '李总', '312', '1578533828@qq.com', 'male');
INSERT INTO `user` VALUES ('6', '34', '王董', '312', '1578533828@qq.com', 'male');
INSERT INTO `user` VALUES ('7', '55', '孙老板', '4321', '1578533828@qq.com', '男');
INSERT INTO `user` VALUES ('8', '19', '陈秘书', '4321', '1578533828@qq.com', '女');
