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。

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>
<html>

	<head>
		<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

<head>
    <meta charset="utf-8"/>
    <title>v-on:按键修饰符</title>
    <script src="js/"></script>
</head>

<!--	@等于v-on:-->
    <input type="text" @"fun"/>
</div>

    //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
练习

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8" />
		<title>v-text与v-html</title>
		<script src="js/"></script>
	</head>

			<div v-text="message"></div>
			<div v-html="message"></div>
		</div>
	</body>
	<script>
		//view model
		new Vue({
			el:"#app",
			data:{
				message:"<h1>hello vue!</h1>"
			}
		})
	</script>
</html>

v-model

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8" />
		<title>v-model</title>
		<script src="js/"></script>
	</head>
	<body>
		<div>
			用户名:<input type="text" v-model=""/><br/>
			密码:<input type="text" v-model=""><br/>
			<input type="button" @click="fun" value="按钮"> 
		</div>
	</body>
	<script>
		//view model
		new Vue({
			el:"#app",
			data:{
				user:{
					username:"test",
					password:"123"
				}
			},
			methods:{
				fun:function () {
					this.="java";
					this.="1234";
				}
			}
		})
	</script>
</html>

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

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8" />
		<title>v-text与v-html在v-bind上的使用</title>
		<script src="js/"></script>
	</head>
	<body>
		<div>
			<font size="5" v-bind:color="ys1">Java</font>
<!--			v-bind等于:-->
			<font siez="5" :color="ys2">web</font>
			<hr/>
			<a :={href:"/index/"+id}>baidu</a>
		</div>
	</body>
	<script>
		//view model
		new Vue({
			el:"#app",
			data:{
				ys1:"red",
				ys2:"green",
				id:1
			}
		})
	</script>
</html>

v-for

(值,键):值在前面,键在后面
操作array

						name: "洗衣机",
						price: 2000}
				]
			}
		})
	</script>
</html>

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

<!DOCTYPE html>

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.
MacOS下VUEJS快速简单学习入门
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');

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
        ();
    }
});
