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

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。

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。

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="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <artifactId>vue</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>war</packaging>

    <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>
<summary>快速入门html代码</summary>

<div id="app">{{message}}</div>
<script>
    new Vue({
        el:'#app',//表示当前vue对象接管了id叫app的div区域
        data:{
            message:'hello vuejs'//注意不要写分号结尾
        }
    });
</script>

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/quickStart.html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index.jsp)

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

                    alert("textarea");
                    event.stopPropagation();//阻止传播到div
                }
            }
        })
    </script>
</html>

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

v-on:事件修饰符

    <script src="js/vuejs-2.5.16.js"></script>
</head>
<body>
    <div id="app">

//不知道为什么.stop没有作用

baidu

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

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/vuejs-2.5.16.js"></script>

        <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>

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

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

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="https://unpkg.com/axios/dist/axios.min.js"></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
axios.get('/user?ID=12345')
.then(function(response){ //得到的响应
        console.log(response);
})
.catch(function(err){//出错
        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);
});

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]])

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@xxx.cn', '男 ');
INSERT INTO `user` VALUES ('2', '31', '刘老师', '123', 'lll@xxx.cn', '女');
INSERT INTO `user` VALUES ('3', '17', '赵工', '213', 'zg@xxx.cn', '女');
INSERT INTO `user` VALUES ('4', '40', '高管', '213', 'gg@xxx.cn', 'female');
INSERT INTO `user` VALUES ('5', '28', '李总', '312', 'lz@jxjt.com', 'male');
INSERT INTO `user` VALUES ('6', '34', '王董', '312', 'wd@jxjt.com', 'male');
INSERT INTO `user` VALUES ('7', '55', '孙老板', '4321', 'slb@xzjt.com', '男');
INSERT INTO `user` VALUES ('8', '19', '陈秘书', '4321', 'cms@xzjt.com', '女');

服务器端

环境搭建和之前的快速入门基本一样

填入配置文件和页面文件

编写User类

目录结构

package org.hacker.domain;

import java.io.Serializable;

/**
 * @author HackerStar
 * @create 2020-05-05 11:02
 */
public class User implements Serializable {
    private Integer id;
    private Integer age;
    private String username;
    private String password;
    private String email;
    private String sex;

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", age=" + age +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                ", email='" + email + '\'' +
                ", sex='" + sex + '\'' +
                '}';
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }
}

Controller

package org.hacker.web.controller;

import org.hacker.domain.User;
import org.hacker.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-05-05 11:28
 */
@Controller
@RequestMapping("/user")
public class UserController {
    @Autowired
    private IUserService userService;

    @RequestMapping("/findAll")
    public List<User> findAll() {
        return userService.findAll();
    }

    @RequestMapping("/findById")
    public User findById(Integer id) {
        return userService.findById(id);
    }

    @RequestMapping("/updateUser")
    public void updateUser(User user) {
        userService.updateUser(user);
    }
}

Service

package org.hacker.service.impl;

import org.hacker.dao.IUserDao;
import org.hacker.domain.User;
import org.hacker.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-05-05 11:35
 */
@Service
public class UserServiceImpl implements IUserService {
    @Autowired
    private IUserDao userDao;

    @Override
    public List<User> findAll() {
        return userDao.findAll();
    }

    @Override
    public User findById(Integer userID) {
        return userDao.findById(userID);
    }

    @Override
    public void updateUser(User user) {
        userDao.updateUser(user);
    }
}


package org.hacker.service;

import org.hacker.domain.User;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-05-05 11:06
 */
public interface IUserService {
    List<User> findAll();

    User findById(Integer userID);

    void updateUser(User user);
}

Dao

package org.hacker.dao;

import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;
import org.hacker.domain.User;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-05-05 11:37
 */
public interface IUserDao {
    @Select("select * from user")
    List<User> findAll();

    @Select("select * from user where id = #{userId}")
    User findById(Integer id);

    @Update("update user set username=#{username}, password=#{password},age=#{age},sex=#{sex},email=#{email} where id=#{id}")
    void updateUser(User user);
}

编写测试类

package org.hacker.test;

import org.hacker.domain.User;
import org.hacker.service.IUserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-05-05 11:43
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class UserTest {
    @Autowired
    private IUserService userService;

    @Test
    public void testFindAll(){
        List<User> users = userService.findAll();
        System.out.println(users);
    }

    @Test
    public void testFindById(){
        User user = userService.findById(1);
        System.out.println(user);
    }

    @Test
    public void testUpdateUser(){
        User user = userService.findById(1);
        user.setUsername("张老师");
        userService.updateUser(user);
    }
}

客户端

这里把主要的精力放在js的编写

user.html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user.js中需要实现的功能名字保持一致，其次就是user.js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

user.js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: '',

            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
            axios.get(
                '/vue/user/findAll.do'
            )
                .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
                    _this.userList = response.data;//响应数据给userList(上边定义了userList)赋值
                    console.log(response);
                })
                .catch(function (erroe) {
                    console.log(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
            axios.get('/vue/user/findById.do', {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
                    _this.user = 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

            var _this = this;//定义this为vue对象，如果在axios中定义则是axios对象
            axios.post('/vue/user/updateUser.do', _this.user)//需要在controller里的updataUser的参数类型前加上@RequsetBody
                .then(function (response) {
                    _this.findAll();
                })
                .catch(function (error) {
                    console.log(error);
                })
        }
    },
    created: function () {//当页面加载时触发请求来查询所有
        this.findAll();
    }
});
