MacOS下VUEJS快速简单学习入门
VueJs概述与快速入门
学习之前假设你已了解关于 HTML、CSS 和 JavaScript 的中级知识。如果你刚开始学习前端开发，将框架作为你的第一步可能不是最好的主意——掌握好基础知识再来吧！之前有其它框架的使用经验会有帮助，但这不是必需的。
VueJs介绍
是一个构建数据驱动的 web 界面的渐进式框架。 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。

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）。 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。
VueJS 快速入门
环境搭建
打开IDEA创建新的工程
使用Maven骨架创建工程
填写工程名称和存放目录
Finish
修改Pom文件
<?xml version="" encoding="UTF-8"?>
<project xmlns="" xmlns:xsi=""
xsi:schemaLocation=" http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId></groupId>
<artifactId>vue</artifactId>
<version>-SNAPSHOT</version>
<packaging>war</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
</project>
补全工程目录
把vuejs文件导入到js目录中，页面导入到webapp下，初期环境准备完毕
编写html文件快速入门
<details>

配置tomcat本地服务器并启动
6.
之后打开浏览器地址栏为http://localhost:8181/vue/效果为(注意地址栏要修改为自己写的快速入门的html文件，因为tomcat默认打开)
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。v
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 } }}

VueJS 常用系统指令
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
v-on:click
练习
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:click</title>
<script src="js/"></script>
</head>
<body>
<div>
{{message}}
<button v-on:click="fun('这是使用vue绑定的单击事件')">vue的onclick</button>
</div>
</body>
<script>
//view model
new Vue({
el:'#app',
data:{
message:'Hello world'
},
methods:{
fun:function (msg) {
this.message = msg;
}
}
});
</script>
</html>
v-on:keydown
练习
<!DOCTYPE html>

<meta charset="utf-8" />
<title>v-on:keydown</title>
<script src="js/"></script>
</head>
<body>
<div>
<input type="text" v-on:keydown="fun($event)">
</div>
</body>
<script>
//view model
new Vue({
el:"#app",
methods:{
fun:function(event){
//alert();
var keyCode = ;
if(!(keyCode >= 48 && keyCode <= 57)) {
//2.阻止默认行为执行
();
}
}
}
})
function showKeyCode(){
var code = ;
alert(code);
}
</script>
</html>
v-on:mouseover
练习
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:mouseover</title>
<style>
#div {
background-color: red;
width: 200px;
height: 200px;
}
</style>
<script src="js/"></script>
</head>
<body>
<div>
<div @mouseover="fun1">
<textarea @mouseover="fun2($event)">这是一个文件域</textarea>
</div>
</div>
</body>
<script>
//view model
new Vue({
el:'#app',
methods:{
fun1:function () {
alert("div");
},
fun2:function (event) {
alert("textarea");
();//阻止传播到div
}
}
})
</script>
</html>
事件修饰符
为 v-on 提供了事件修饰符来处理 DOM 事件细节，如：() 或()。
通过由点(.)表示的指令后缀来调用修饰符。
.stop.prevent.capture.self.once
练习
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>v-on:事件修饰符</title>
<script src="js/"></script>
</head>
<body>
<div>
<!-- 加入.prevent阻止提交-->
<form v-on:submit.prevent action="">
<input type="submit" value="Go"/>
</form>
//不知道为什么.stop没有作用
<div v-on:click="fun">
<a v-on:click.stop href="">baidu</a>
</div>
</div>
</body>
<script>
//view model
new Vue({
el:'#app',
methods:{
fun:function(){
alert("prevent");
}
}
});
</script>
</html>
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
练习
不知道为什么没有效果

</body>
<script>
//view model
new Vue({
el:'#app',
methods:{
fun:function () {
alert("aaa");
}
}
})
</script>
</html>
v-text与v-html
v-text:将内容原封不动显示
v-html:会将标签解析

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
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>vuejs生命周期</title>
<script src="js/"></script>
</head>
<body>
<div>
{{message}}
</div>
</body>
<script>
var vm = new Vue({
el: "#app",
data: {
message: 'hello world'
},
beforeCreate: function() {
(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() {
('真实dom结构：' + ('app').innerHTML);
}
function showData(process, obj) {
(process);
('data 数据：' + )
('挂载的对象：')
(obj.$el)
realDom();
('------------------')
('------------------')
}
//vm.message = "good...";
vm.$destroy();
</script>
</html>
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方法
- 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
VueJS ajax
vue-resource
vue-resource是的插件提供了使用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
axios
Axios 是一个基于 promise 的 HTTP 库，可以用在浏览器和 中
axios的github:
引入axios
首先就是引入axios,如果你使用es6，只需要安装axios模块
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=""></script>
也可以下载到本地，引入本地的js文件
get请求
//通过给定的ID来发送请求
('/user?ID=12345')
.then(function(response){ //得到的响应
(response);
})
.catch(function(err){//出错
(err);
});
//以上请求也可以通过这种方式来发送
('/user',{params:{ID:12345}})
.then(function(response){
(response);
})
.catch(function(err){
(err);
});
post请求
('/user',{
firstName:'Fred',
lastName:'Flintstone'
})
.then(function(res){
(res);
})
.catch(function(err){
(err);
})
为方便起见，为所有支持的请求方法提供了别名
(config)
(url[, config])
(url[, config])
(url[, config])
(url[, data[, config]])
(url[, data[, config]])
(url[, data[, config]])
综合案例
案例需求
完成用户的查询与修改操作
数据库设置与表结构
创建数据库和插入数据
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', '33', '张老师', '123', 'zzz@', '男 ');
INSERT INTO `user` VALUES ('2', '31', '刘老师', '123', 'lll@', '女');
INSERT INTO `user` VALUES ('3', '17', '赵工', '213', 'zg@', '女');
INSERT INTO `user` VALUES ('4', '40', '高管', '213', 'gg@', 'female');
INSERT INTO `user` VALUES ('5', '28', '李总', '312', 'lz@', 'male');
INSERT INTO `user` VALUES ('6', '34', '王董', '312', 'wd@', 'male');
INSERT INTO `user` VALUES ('7', '55', '孙老板', '4321', 'slb@', '男');
INSERT INTO `user` VALUES ('8', '19', '陈秘书', '4321', 'cms@', '女');

客户端
这里把主要的精力放在js的编写
页面
修改中资源位置，比如本项目定义的tomcat目录为/vue，各个插件获取时需要到/vue目录下来获取相应的资源，其次在实现findById时，需要开启modal，之后获取数据(使用了findById方法)在小页面获取到原来的信息，之后可以修改内容在点击修改即可修改数据库的内容，此处需要注意定义'修改'标签那里的@click="updateUser"中@click的名字要和中需要实现的功能名字保持一致，其次就是编写时，需要把功能方法先搭建起来(就是只有方法名，内容先不用填写)，否则实现了一个功能，虽然代码没错，但是浏览器的console会产生‘没有其他方法’的异常

页面
功能一个一个的实现，首先编写findAll，测试，之后findById，测试，之后updateUser，测试
new Vue({
el: "#app",
data: {
user: {
is: '',
username: '',
password: '',
email: '',
age: '',
sex: ''
},
userList: []
},
methods: {
findAll: function () {
var _this = this;//定义this为vue对象，如果在axios中定义则是axios对象
(
'/vue/user/'
)
.then(function (response) {//需要在controller里加上@ResponseBody,直接加在类上就不用在每个需要加的方法上加了
List = response.data;//响应数据给userList(上边定义了userList)赋值
(response);
})
.catch(function (erroe) {
(error);
})
},
findById: function (userId) {
var _this = this;//定义this为vue对象，如果在axios中定义则是axios对象
('/vue/user/', {params:{id:userId}})
.then(function (response) {//需要在controller里加上@ResponseBody,直接加在类上就不用在每个需要加的方法上加了
= response.data;//响应数据给user(上边定义了user)
$("#myModal").modal("show");//开启编辑修改功能
})
.catch(function (error) {
(error);
})
},
updateUser: function (user) {//post请求
var _this = this;//定义this为vue对象，如果在axios中定义则是axios对象
('/vue/user/', )//需要在controller里的updataUser的参数类型前加上@RequsetBody
.then(function (response) {
();
})
.catch(function (error) {
(error);
})
}
},
created: function () {//当页面加载时触发请求来查询所有
();
}
});
结果
THE END
