大型项目技术栈第一讲 Vue.js的使用
Vue.js的使用
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。
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
1.3 VueJS 快速入门
1.3.1创建Module
1.3.2 然后修改名字–>Next–>完成;完成后里面是空的
1.3.3 在项目下创建js文件夹,将vuejs.js文件放入js文件夹,这个是工具
1.3.4 创建mode.html(下面就是,其也是快速入门案例)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!--
直接下载并用 <script> 标签引入，Vue 会被注册为一个全局变量。
重要提示：在开发时请用开发版本，遇到常见错误它会给出友好的警告
-->
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
{{info}}
</div>
<script>
new Vue({
el:"#app", //表示当前Vue对象管理div区域
data:{
info:"Vue_HelloWorld"
}
});
</script>
</body>
</html>Vue调试神器vue-devtools
vue-devtools是一款基于chrome游览器的插件，用于调试vue应用，这可以极大地提高我们的调试效率
游览器输入地址“chrome://extensions/”进入扩展程序页面，点击“加载已解压的扩展程序…”按钮，选择解压好的vue-devtools文件夹。
如果看不见“加载已解压的扩展程序…”按钮，则需要勾选“开发者模式”。
到此添加完成，效果图如下：
打开vue项目,在控制台选择vue：
7.点击vue，查看数据
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' }}例如：
<body>
<div id="app">
{{number+1}}
<hr>
{{flag?"东方标准":"小标"}}
</div>
<script>
new Vue({
el:"#app", //表示当前Vue对象管理div区域
data:{
info:"Vue_HelloWorld",
number:1,
flag:true
}
});
</script>
</body>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 } }}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
<!DOCTYPE html>
<html lang="en" xmlns:v-on="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app" v-on:click="fun1('vue的点击事件触发啦！')" style="width: 200px;height: 200px;border:1px solid red;">
{{info}}
</div>
<script>
new Vue({
el: "#app",
data: {
info:"我是div"
},
methods:{
fun1:function (msg) {
this.info=msg;
}
}
});
</script>
</body>
</html>2.1.2 v-on:keydown
<!DOCTYPE html>
<html xmlns:v-on="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8"/>
<title>事件处理 v-on示例2</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<input type="text" v-on:keydown="fun2($event)">
</div>
<script>
new Vue({
el: '#app',
methods: {
fun2: function (e) {
//只能输入数字
if(!(e.keyCode>=48 && e.keyCode<=57)){
e.preventDefault(); //阻止事件默认行为
}
}
}
});
</script>
</body>
</html>$event-事件对象 使用不带圆括号的形式，event 对象将被自动当做实参传入:v-on:keydown=“fun2” 使用带圆括号的形式，我们需要使用 event 变量显式传入 event 对象:v-on:keydown=“fun2(event)” preventDefault()-阻止默认事件
2.1.3 v-on:mouseover
<!DOCTYPE html>
<html xmlns:v-on="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>事件处理 v-on示例3</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<div v-on:mouseover="fun1" id="div" style="background:red;">
<textarea v-on:mouseover="fun2($event)">这是一个文件域</textarea>
</div>
</div>
<script>
new Vue({
el : '#app',
methods : {
fun1 : function() {
alert("div");
},
fun2 : function(event) {
alert("textarea");
event.stopPropagation();//阻止冒泡
}
}
});
</script>
</body>
</html>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() event.stopPropagation()
Vue.js通过由点(.)表示的指令后缀来调用修饰符。
- .stop：阻止事件冒泡
- .prevent：阻止事件默认行为
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">
<!--阻止默认事件-->
<form @submit.prevent action="http://www.baidu.com">
<input type="submit">
</form>
<hr>
<!--阻止事件冒泡-->
<div @click="fun1">
<a @click.stop href="https://www.jd.com">京东</a>
</div>
</div>
<script>
new Vue({
el:"#app",
methods:{
fun1:function () {
alert("div！");
}
}
})
</script>
</body>
</html>v-on简写方式
<!-- 完整语法 -->
<a v-on:click="doSomething">...</a>
<!-- 缩写 -->
<a @click="doSomething">...</a><!-- 阻止单击事件继续传播 -->
<a v-on:click.stop="doThis"></a>
<!-- 提交事件不再重载页面 -->
<form v-on:submit.prevent="onSubmit"></form>
<!-- 修饰符可以串联 -->
<a v-on:click.stop.prevent="doThat"></a>
<!-- 只有修饰符 -->
<form v-on:submit.prevent></form>
<!-- 添加事件监听器时使用事件捕获模式 -->
<!-- 即元素自身触发的事件先在此处理，然后才交由内部元素进行处理 -->
<div v-on:click.capture="doThis">...</div>
<!-- 只当在 event.target 是当前元素自身时触发处理函数 -->
<!-- 即事件不是从内部元素触发的 -->
<div v-on:click.self="doThat">...</div>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：
.enter
.tab
.delete (捕获 “删除” 和 “退格” 键)
.esc
.space
.up
.down
.left
.right
.ctrl
.alt
.shift
.meta

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

</html>3.VueJS生命周期（了解）
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:创建VUE对象之前执行，此时data中的数据还未初始化，el还未关联到对应的id
- created:创建VUE对象之后执行,此时data中的数据已经初始化，但el还未关联到对应的id
- beforeMount:对象挂载之前执行，此时el已经关联到对应对象,但{{}}表达式还未加载
- mounted:对象挂载之后执行,此时{{}}表达已经加载，执行完mounted之后开始正常执行js代码
- beforeUpdate:data数据更新前执行，此时data中的数据已经更新，但是{{}}表达式中引用的还没有更新
- updated:数据更新后执行,{{}}表达式中引用也更新
- beforeDestory:vue对象销毁前执行
- destroyed:vue对象销毁后执行
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
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>生命周期</title>
<script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
<div id="app">{{message}}</div>
<script>
var v = 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 showData(process, obj) {
console.log(process);
console.log('data 数据：' + obj.message);
console.log('挂载的对象：');
console.log(obj.$el);
console.log('真实dom结构：' + document.getElementById('app').innerHTML);
console.log('------------------');
}
v.message = "update Data...";
v.$destroy();
</script>
</body>
</html>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模块即可
import axios from 'axios';
//安装方法
npm install axios
//或
bower install axios
当然也可以用script引入
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>4.2.2 get请求
//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
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
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
User表：
/*Table structure for table `user` */
CREATE TABLE `user` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`username` VARCHAR(50) DEFAULT NULL,
`password` VARCHAR(50) DEFAULT NULL,
`name` VARCHAR(50) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
/*Data for the table `user` */
INSERT INTO `user`(`id`,`username`,`password`,`name`) VALUES (1,'zhangsan','123','张三');
INSERT INTO `user`(`id`,`username`,`password`,`name`) VALUES (2,'lisi','123','李四'); User类：
public class User {
private Integer id;//主键
private String username;//用户名
private String password;//密码
private String name;//姓名
//此处省略getter和setter方法 .. ..
