建议选择id选择器

<script>
var app = new Vue({
// el:"#app",
// el:".app",
// el:"div",
el:"#body",
data:{
message:"黑马程序员"
}
})
</script>
</body>
</html>el挂载作用：
Vue实例的作用范围是什么呢？
Vue会管理el选项命中的元素及其内部的后代元素
是否可以使用其他的选择器？
可以使用其他的选择器，但是建议使用引D选择器
是否可以设置其他的dom元素呢？
可以使用其他的双标签，不能使用HTML和BODY
1.3.data数据对象
◆Vue中用到的数据定义在data中
◆data中可以写复杂类型的数据
◆渲染复杂类型数据时，遵守js的语法即可
(1)对象
数据获取：对象.属性
（2)数组
数据获取：数组[下标]
代码示例
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">

data:{

}
})
</script>
</body>
</html>2.本地应用
2.1.内容绑定，事件绑定
v-text
1.v-text指令的作用是：设置标签的内容(textContent)
2.默认写法会替换全部内容，使用差值表达式{}可以替换指定内容
3.表达式
v-html
◆v-html指令的作用是：设置元素的innerHTML
◆内容中有html结构会被解析为标签
◆v-text指令无论内容是什么，只会解析为文本
◆解析文本使用v-text,需要解析html结构使用v-html
v-on基础
◆v-on指令的作用是：为元素绑定事件
◆事件名不需要写on
◆指令可以简写为@
◆绑定的方法定义在methods属性中
作用2：
传递自定义参数，事件修饰符
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>
<body>
<div id="app">
<input type="button" value="点击" @click="doIt(666,'老铁')">
<input type="text" @keyup.enter="sayHi">
</div>
<!-- 1.开发环境版本，包含了有帮助的命令行警告 -->
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app = new Vue({
el:"#app",
methods: {
doIt:function(p1,p2){
console.log("做it");
console.log(p1);
console.log(p2);
},
sayHi:function(){
alert("吃了没");
}
},
})
</script>
</body>
</html>总结：
◆事件绑定的方法写成函数调用的形式，可以传入自定义参数
◆定义方法时需要定义形参来接收传入的实参
◆事件的后面跟上。修饰符可以对事件进行限制
◆.enter可以限制触发的按键为回车
结合使用：计数器
实现代码：
css
body{
background-color: #f5f5f5;
}
#app {
width: 480px;
height: 80px;
margin: 200px auto;
}
.input-num {
margin-top:20px;
height: 100%;
display: flex;
border-radius: 10px;
overflow: hidden;
box-shadow: 4px 4px 4px #adadad;
border: 1px solid #c7c7c7;
background-color: #c7c7c7;
}
.input-num button {
width: 150px;
height: 100%;
font-size: 40px;
color: #ad2a27;
cursor: pointer;
border: none;

background-color:rgba(0, 0, 0, 0);
}

<!-- 编码 -->
<script>
// 创建Vue实例
var app = new Vue({
el: "#app",
data: {
num: 1,
min: 0,
max: 10
},
methods: {
sub() {
if (this.num > this.min) {
this.num--;
} else {
alert("别点啦,到底啦");
}
},
add() {
if (this.num < this.max) {
this.num++;
} else {
alert("别点啦,到头啦");
}
}
}
});
</script>
计数器知识总结：
◆创建Vue示例时：el（挂载点），data（数据），methods（方法）
◆v-on指令的作用是绑定事件，简写为@
◆方法中通过this,关键字获取data中的数据
◆v-text指令的作用是：设置元素的文本值，简写为{0}
◆v-html指令的作用是：设置元素的innerHTML
2.2.显示切换，属性绑定
v-show
根据表达值的真假，切换元素的显示和隐藏（样式）
◆V-show指令的作用是：根据真假切换元素的显示状态
◆原理是修改元素的display,实现显示隐藏
◆指令后面的内容，最终都会解析为布尔值
◆值为true元素显示，值为false元素隐藏
v-if
根据表达式的真假噢，切换元素的显示和隐藏（操纵dom元素）
◆V-指令的作用是：根据表达式的真假切换元素的显示状态
◆本质是通过操纵dom元素来切换显示状态
◆表达式的值为true,元素存在于dom树中，为false,从dom树中移除

</body>
</html>v-bind
设置元素属性（scr\title\class）
◆v-bind指令的作用是：为元素绑定属性
◆完整写法是v-bind:属性名
◆简写的话可以直接省略v-bind,只保留：属性名
需要动态的增删class建议使用对象的方式

例题总结：
◆列表数据使用数组保存
◆v-bind指令可以设置元素属性，比如src
2.3.列表循环表单元素绑定
v-for
根据数据生成列表结构
◆V-fo指令的作用是：根据数据生成列表结构
◆数组经常和v-for结合使用
◆语法是(item,inde)in数据
◆item和index可以结合其他指令一起使用
◆数组长度的更新会同步到页面上，是响应式的

综合例题
1.新增功能知识要点
1.生成列表结构(v-for数组)
2.获取用户输入(v-model)
3.回车，新增数据(v-on.enter添加数据)
5.隐藏
1.没有数据时，隐藏元素(W-show v-if数组非空)
总结
◆列表结构可以通过v-fo指令结合数据生成
◆v-on结合事件修饰符可以对事件进行限制，比如。enter
◆v-on在绑定事件时可以传递自定义参数
◆通过v-modeli可以快速的设置和获取表单元素的值
◆基于数据的开发方式

3.网络应用
Vue结合网络数据开发应用
3.1axios基本使用
◆axios必须先导入才可以使用
◆使用get或post方法即可发送对应的请求
◆then方法中的回调函数会在请求成功或失败时触发
◆通过回调函数的形参可以获取响应内容，或错误信息
例题axios基本使用
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="X-UA-Compatible" content="ie=edge" />
<title>axios基本使用</title>
</head>
<body>
<input type="button" value="get请求" class="get" />
<input type="button" value="post请求" class="post" />
<!-- 官网提供的 axios 在线地址 -->
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script>
/*
接口1:随机笑话
请求地址:https://autumnfish.cn/api/joke/list
请求方法:get
请求参数:num(笑话条数,数字)
响应内容:随机笑话
*/
document.querySelector(".get").onclick = function () {
axios
.get("https://autumnfish.cn/api/joke/list?num=6")
// axios.get("https://autumnfish.cn/api/joke/list1234?num=6")
.then(
function (response) {
console.log(response);
},
function (err) {
console.log(err);
}
);
};
/*
接口2:用户注册
请求地址:https://autumnfish.cn/api/user/reg
请求方法:post
请求参数:username(用户名,字符串)
响应内容:注册成功或失败
*/
document.querySelector(".post").onclick = function () {
axios
.post("https://autumnfish.cn/api/user/reg", { username: "你好" })
.then(
function (response) {
console.log(response);
console.log(this.skill);
},
function (err) {
console.log(err);
}
);
};
</script>
</body>
</html>
3.2. axios和vue使用
注意点：
axios回调函数中的this已经改变，无法访问到data中数据
把this保存起来，回调函数中直接使用保存的this即可
网络应用 天气
1.回车查询
小结：
◆应用的逻辑代码建议和页面分离，使用单独的s文件编写
◆axios回调函数中this指向改变了，需要额外的保存一份
◆服务器返回的数据比较复杂时，获取的时候需要注意层级结构
2.点击查询
1.点击城市(v-on自定义参数)
2.查询数据
(this.方法0)
3.渲染数据
例题小结：
◆自定义参数可以让代码的复用性更高
◆methods中定义的方法内部，可以通过this关键字点出其他的方法

综合使用 音乐播放器
功能
1歌曲搜索
◆服务器返回的数据比较复杂时，获取的时候需要注意层级结构
◆通过审查元素快速定位到需要操纵的元素
2.歌曲播放
1.点击播放(N-on自定义参数)
2.歌曲地址获取(接口歌曲id)
3.歌曲地址设置(v-bind)
3歌曲封面
1.点击播放（增加逻辑）
2.歌曲封面获取(接口歌曲id)
3.歌曲封面设置(v-bind)
4.歌曲评论
1.点击播放（增加逻相）
2.歌曲评论获取(接口歌曲id)
3.歌曲评论渲染(w-for)
5播放动画
1.监听音乐播放(v-on play)
2.监听音乐暂停(v-on pause)
3.操纵类名(v-bind对象)
◆audio标签的play事件会在音频播放的时候触发
audio标签的pause事件会在音频暂停的时候触发
◆通过对象的方式设置类名，类名生效与否取决于后面值的真假
6.mv播放（mv播放api失效）
1.mv图标显示（v-if
2.mv地址获取(接口mvid)
3.遮罩层(v-show v-on)
4.mv地址设置(v-bind)
