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
分析:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>快速入门</title> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> {{message}}<!--Vue的插值表达式,把data中定义的数据显示到此处--> </div> </body> <script> //view model //创建Vue对象 new Vue({ el: "#app",//vue接管id为app区域 data: { message: "Hello Vue! EESY"//注意:此处不要加分号 } }); </script> </html>
数据绑定 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;}}
{{if(a=10){}}
<!--流程控制也不会生效,请使用三元表达式-->
{{ if(ok) {return message }}
可以用 v-on 指令监听 DOM 事件,并在触发时运行一些 JavaScript 代码
格式:v-on:事件
或@事件
<!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')">vue的onclick</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 world'//注意不要写分号结尾 }, methods:{ fun1:function (msg) { this.message=msg; } } }) </script> </html>
<!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($event)"> <hr/> 传统js:<input type="text" onkeydown="showKeyCode()"> </div> </body> <script> //view model new Vue({ el: "#app", methods: { fun: function (event) { var keyCode = event.keyCode; if (keyCode < 48 || keyCode > 57) { event.preventDefault(); } } } }); //传统js的键盘按下事件 function showKeyCode() { //event对象和我们的document对象以及window对象是一样,可以不用定义直接使用 var keyCode = event.keyCode; if (keyCode < 48 || keyCode > 57) { event.preventDefault(); } // alert(keyCode); // if(event.keyCode==13){ // alert("你按的是回车") // } } </script> </html>
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>v-on:mouseover</title> <style> #div { background-color: red; width: 300px; height: 200px; } </style> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> <div @mouseover="fun1" id="div"> <textarea @mouseover="fun2($event)">这是一个文件域</textarea> </div> <!--<div οnmοuseοver="divmouseover()" id="div">--> <!--<textarea οnmοuseοver="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-no:mouseover */ new Vue({ el:"#app", methods:{ fun1:function () { alert("鼠标移动到div上了") }, fun2:function (event) { alert("鼠标移动到了textarea上了"); event.stopPropagation(); } } }); // //传统的js方式 // function divmouseover() { // alert("鼠标移动到div上了"); // } // // function textareamouseover() { // alert("鼠标移动到了textarea上了"); // event.stopPropagation(); // } </script> </html>
注意:@
是v-on:
的简写方式
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
:停止传播.prevent
:阻止行为.capture
:捕获.self
:本身触发(不从内部元素触发).once
:只会触发一次.passive
:先触发默认事件,然后触发调用的方法(移动端)注意:修饰符可以串联,并且可以只有修饰符
,不要把 .passive 和 .prevent 一起使用,因为 .prevent 将会被忽略
使用修饰符时,顺序很重要;相应的代码会以同样的顺序产生。因此,
用 v-on:click.prevent.self 会阻止所有的点击,
而 v-on:click.self.prevent 只会阻止对元素自身的点击。
例子:进行阻止进行跳转
vue
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>v-on 事件修饰符</title> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"><!--.prevent 表示阻止跳转--> <form @submit.prevent action="http://www.itcast.cn" method="get"><input type="submit" value="提交"/></form> <div @click="fun1"><a @click.stop href="http://www.itcast.cn">itcast</a></div> </div> <script> new Vue({ el: '#app', //表示当前vue对象接管了div区域 methods:{ fun1:function(){ alert("hello itcast"); } } }); </script> </body> </html>
传统js
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>v-on:事件修饰符</title> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> <form action="http://www.ithiema.com" method="post" onsubmit="return checkForm()"> <input type="submit"> </form> </div> </body> <script> //传统js function checkForm() { return false; } </script> </html>
.enter
.tab
.delete (捕获 "删除" 和 "退格" 键)
.esc
.space
.up
.down
.left
.right
.ctrl
.alt
.shift
.meta
等等
<!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"><!--.enter表示按下回车时--> Vue:<input type="text" @keydown.enter="fun1"> </div> </body> <script> //view model new Vue({ el: "#app", methods: { fun1: function () { alert("按下的是回车") } } }) </script> </html>
innerHTML
与innerText
进行代替<!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"> vue <div v-text="message"></div> <div v-html="message"></div> <hr> 传统js <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 window.onload = function (ev) { document.getElementById("div1").innerHTML = "<h1>Hello</h1>"; document.getElementById("div2").innerText = "<h1>Hello</h1>"; } </script> </html>
可以解决插值表达式,在网络速度慢的情况下,闪速的问题
对属性进行动态绑定赋值,格式:v-bind:属性
或:属性
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>v-bind</title> <style type="text/css"> </style> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> <font size="5" :color="ys1">传智播客</font> <font size="5" :color="ys2">黑马程序员</font> </div> </body> <script> //view model //插值表达式不能用于html标签的属性取值 //要想给html标签的属性设置变量的值,需要使用v-bind //b-bind也可以简化写法 直接使用: new Vue({ el: "#app", data: { ys1: "red", ys2: "green" } }) </script> </html>
注意:
插值表达式不能用于html标签的属性取值
要想给html标签的属性设置变量的值,需要使用v-bind
b-bind也可以简化写法 直接使用:
v-bind简写方式:
<!-- 完整语法 -->
<a v-bind:href="url">...</a>
<!-- 缩写 -->
<a :href="url">...</a>
补充:可以进行Class与Css的绑定
官方文档链接
在data中取出json数据进行赋值
或进行表单输入绑定
(双向数据绑定)
<!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" name="username" v-model="user.username"><br> 密码:<input type="password" name="password" v-model="user.password"><br> </div> </body> <script> //view model new Vue({ el: "#app", data: { user: { username: "test", password: "1234" } } }) </script> </html>
补充:可以进行表单的绑定官方表单输入绑定教程链接
注意:只进行有输入框的进行双向数据绑定
进行数据遍历展示
数组
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>v-for遍历数组</title> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> <ul> <li v-for="(item,index) in arr">{{item}}={{index}}</li> </ul> </div> </body> <script> //view model new Vue({ el: "#app", data: { arr: [1, 2, 3, 4, 5] } }) </script> </html>
arr
:源数据数组
item
:被迭代的数组元素的别名
index
:当前项的索引
可以用 of 替代 in 作为分隔符,因为它更接近 JavaScript 迭代器的语法
"("与")"可以不写
对象
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>v-for遍历对象</title> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> <ul> <li v-for="(key,value) in product">{{value}}==={{key}}</li> </ul> </div> </body> <script> //view model new Vue({ el: "#app", data: { product: { id: 1, name: "笔记本电脑", price: 5000 } } }) </script> </html>
对象数组
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>v-for遍历对象</title> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> <table border="1"> <tr> <td>序号</td> <td>编号</td> <td>名称</td> <td>价格</td> </tr> <tr v-for="(product,index) in products"> <td>{{index}}</td> <td>{{product.id}}</td> <td>{{product.name}}</td> <td>{{product.price}}</td> </tr> </table> </div> </body> <script> //view model new Vue({ el: "#app", data: { products: [ {id: 1, name: "笔记本电脑", price: 5000}, {id: 2, name: "手机", price: 3000}, {id: 3, name: "电视", price: 4000} ] } }) </script> </html>
补充:可以提供第二个的参数为 property 名称 (也就是键名):
<div v-for="(value, name) in object">
{{ name }}: {{ value }}
</div>
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
在使用两个几乎没有区别,使用if切换时消失标签,而show只进行隐藏
切换显示还是不显示
<!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">传智播客</span> <span v-show="flag">itcast</span> <button @click="toggle">切换</button> </div> </body> <script> //view model new Vue({ el: "#app", data: { flag: false }, methods: { toggle: function () { this.flag = !this.flag; } } }) </script> </html>
可以用 v-else
添加一个“else 块”
<h1 v-if="awesome">Vue is awesome!</h1>
<h1 v-else>Oh no ?</h1>
v-else
元素必须紧跟在带 v-if
或者v-else-if
的元素的后面,否则它将不会被识别
v-else-if
,顾名思义,充当 v-if 的“else-if 块”,可以连续使用
<div v-if="type === 'A'">
A
</div>
<div v-else-if="type === 'B'">
B
</div>
<div v-else-if="type === 'C'">
C
</div>
<div v-else>
Not A/B/C
</div>
类似于 v-else
,v-else-if
也必须紧跟在带 v-if
或者 v-else-if
的元素之后。
v-show
v-show
指令v-show
的元素始终会被渲染并保留在 DOM 中。v-show
只是简单地切换元素的 CSS 属性 displayv-show
不支持 <template>
元素,也不支持 v-else
v-show与v-if的区别
v-if
是“真正”的条件渲染,因为它会确保在切换过程中条件块内的事件监听器和子组件适当地被销毁和重建。
v-if
也是惰性的:如果在初始渲染时条件为假,则什么也不做——直到条件第一次变为真时,才会开始渲染条件块。
相比之下,v-show
就简单得多——不管初始条件是什么,元素总是会被渲染,并且只是简单地基于 CSS 进行切换。
一般来说,v-if
有更高的切换开销,而 v-show
有更高的初始渲染开销。因此,如果需要非常频繁地切换,则使用 v-show
较好;如果在运行时条件很少改变,则使用 v-if
较好。
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>生命周期</title> <script src="js/vuejs-2.5.16.js"></script> </head> <body> <div id="app"> {{message}}</div> <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> </body> </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
8个生命周期的执行点
4个基本的
4个特殊的
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
Axios 是一个基于 promise 的 HTTP 库,可以用在浏览器和 node.js
axios的github
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
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
//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);
});
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]])
它和jquery的ajax比较相似
