vue快速学习02、基础用法
1、数据双向绑定
<!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">

</head>
<body>
<!--视图层-->
<div id="app">
<input type="text" v-model="Msg"><br/>
<p>{{Msg}}</p>
</div>
<!--引入vue环境-->
<script src="js/vue.js"></script>
<!--视图模型层-->
<script>
/* Vue的基础使用方法，内部参数格式为json*/
new Vue({
el: "#app",
data: {
Msg: "天使之吻"
}
})
</script>
</body>
</html>

return o.name.indexOf(_this.SelectKey) != -1;
});
}
},
methods: {
addInfo: function() {
this.list.push({
id: this.id,
name: this.name,
price: this.price,
sex: this.sex
});
},
del: function(o) {
if (confirm('是否删除此行?')) {
this.list.splice(o, 1);
}
}
}
})
</script>
</body>
</html>
20、table修改
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

</head>
<body>
<!-- 视图层 -->
<div id="app">

</table>
</div>
<!-- 环境 -->
<script src="https://cdn.staticfile.org/vue/2.4.2/vue.min.js"></script>
<!-- 视图模型 -->
<script>
new Vue({
el: "#app",
data: {
list: [{

this.list[index].sex = this.sex;
return;
}
}
}
}
})
</script>
</body>
</html>
21、template
基础声明
<!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>Document</title>
</head>
<body>
<div id="app">
<myheart></myheart>
</div>
<script src="js/vue.js"></script>
<script>
//搭建母版
var myheart_tem = Vue.extend({
template: "<div><h1>My Heart Will Go On</h1><hr/><p>爱无止境·肉丝·杰克</p></div>"
});
//创建组件，第一个参数是自定义组件名称，母版
Vue.component("myheart", myheart_tem);
//创建VUE
new Vue({
el: "#app"
})
</script>
</body>
</html>
**template简单使用 **
<!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>Document</title>
<style>
* {
margin: 0px;
padding: 0px;
}
body {
overflow: hidden;
}
.myh {
background: #2E6EC2;
height: 10vh;
color: white;
font-size: 3rem;
line-height: 10vh;
}
.myc {
background-color: #F8F1DC;
text-align: center;
height: 85vh;
font-size: 5rem;
line-height: 85vh;
}
.myf {
background: #2E6EC2;
text-align: center;
height: 5vh;
color: white;
font-size: 2rem;
line-height: 5vh;
}
</style>
</head>
<body>
<div id="app">
<myhead></myhead>
<mycontent></mycontent>
<myfoot></myfoot>
</div>
<!-- 环境 -->
<script src="https://cdn.staticfile.org/vue/2.4.2/vue.min.js"></script>
<script>
//创建母版
var head = Vue.extend({
template: "<div class='myh'>后台管理系统</div>"
});
var content = Vue.extend({
template: "<div class='myc'>后台管理中心内容</div>"
});
var foot = Vue.extend({
template: "<div class='myf'>版权所有：项目开发组</div>"
});
//绑定组件
Vue.component("myhead", head);
Vue.component("mycontent", content);
Vue.component("myfoot", foot);
new Vue({
el: "#app"
})
</script>
</body>
</html>
22、components绑定组件
<!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>Document</title>
</head>
<body>
<div id="app">
<h1>一堆水果的遍历</h1>
<!-- 需要的自定义的组件 -->
<show-fruit></show-fruit>
</div>
<!-- 模板·在APP的外面 -->
<template id="show">
<div>
<ul>
<li v-for="item in list">{{item}}</li>
</ul>
</div>
</template>
<!-- 环境 -->
<script src="https://cdn.staticfile.org/vue/2.4.2/vue.min.js"></script>
<script>
new Vue({
el: "#app",
components: { //绑定组件
"show-fruit": {
data: function() {
return {
list: ["百香果", "蛇皮果", "姑娘果", "莲雾", "雪莲果"]
}
},
template: "#show"
}
}
})
</script>
</body>
</html>
23、props传值
<!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>Document</title>
<link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://cdn.staticfile.org/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div id="app">
<h1 align="center">员工信息表</h1>
<!-- 自定义组件名称 -->
<showlist :newlist="list"></showlist>
</div>
<!-- 组件的模板 -->
<template id="show">
<table class="table table-border" style="text-align: center">
<tr class="info">
<td>编号</td>
<td>诗词名称</td>
<td>作者</td>
<td>经典词语</td>
</tr>
<tr v-for="item in newlist">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.worker}}</td>
<td><pre>{{item.classic}}</pre></td>
</tr>
</table>
</template>
<!-- 环境 -->
<script src="https://cdn.staticfile.org/vue/2.4.2/vue.min.js"></script>
<script>
new Vue({
el: "#app",
data: {
list: [{
id: 1,
name: "《将进酒》",
worker: "李白",
classic: "烹羊宰牛且为乐，会须一饮三百杯！"
}, {
id: 2,
name: "《夏日绝句》",
worker: "李清照",
classic: "生当作人杰，死亦为鬼雄！"
}, {
id: 3,
name: "《长恨歌》",
worker: "白居易",
classic: "回眸一笑百媚生，六宫粉黛无颜色。"
}, {
id: 4,
name: "《锦瑟》",
worker: "李商隐",
classic: "锦瑟无端五十弦，一弦一度思华年！"
}]
},
components: {
"showlist": {
props: ["newlist"],
template: "#show"
}
}
})
</script>
</body>
</html>
24、components子父组件的使用
<!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>Document</title>
<link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://cdn.staticfile.org/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div id="app">
<h1>员工管理系统</h1>
<!-- 父类组件 -->
<fu-temp :showlist="list"></fu-temp>
</div>
<!-- 父类模板 -->
<template id="fu">
<div>
搜索：<input type="text" v-model="SelectKey" placeholder="请输入搜索内容"/>
<hr/>
<zi-temp :newlist="filterlist"></zi-temp>
</div>
</template>
<!-- 子类模板 -->
<template id="zi">
<div>
<table class="table table-border" style="text-align: center">
<tr class="info">
<td>编号</td>
<td>诗词名称</td>
<td>作者</td>
<td>经典词语</td>
</tr>
<tr v-for="item in newlist">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.worker}}</td>
<td><pre>{{item.classic}}</pre></td>
</tr>
</table>
</div>
</template>
<!-- 环境 -->
<script src="https://cdn.staticfile.org/vue/2.4.2/vue.min.js"></script>
<script>
new Vue({
el: "#app",
data: {
list: [{
id: 1,
name: "《将进酒》",
worker: "李白",
classic: "烹羊宰牛且为乐，会须一饮三百杯！"
}, {
id: 2,
name: "《夏日绝句》",
worker: "李清照",
classic: "生当作人杰，死亦为鬼雄！"
}, {
id: 3,
name: "《长恨歌》",
worker: "白居易",
classic: "回眸一笑百媚生，六宫粉黛无颜色。"
}, {
id: 4,
name: "《锦瑟》",
worker: "李商隐",
classic: "锦瑟无端五十弦，一弦一度思华年！"
}]
},
components: {
"fu-temp": {
props: ["showlist"],
data: function() {
return {
SelectKey: ""
}
},
template: "#fu",
components: {
"zi-temp": {
props: ["newlist"],
template: "#zi"
}
},
computed: {
filterlist: function() {
var _this = this;
return _this.showlist.filter(function(o) {
return o.classic.indexOf(_this.SelectKey) != -1;
});
}
}
}
}
});
</script>
</body>
</html>
25、slot插槽使用
<!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>Document</title>
</head>
<body>
<div id="app">
<h1>三好学生遍历</h1>
<!-- 声明自定义组件 -->
<showinfo :newlist="list">
<template slot="cache" slot-scope="props">
<li>{{props.item}}</li>
</template>
</showinfo>
</div>
<template id="show">
<div>
<slot name="cache" v-for="item in newlist" :item="item"></slot>
</div>
</template>
<!-- 环境 -->
<script src="https://cdn.staticfile.org/vue/2.4.2/vue.min.js"></script>
<script>
new Vue({
el: "#app",
data: {
list: ["王佳乐", "张雄飞", "宋建飞"]
},
components: {
"showinfo": {
props: ["newlist"],
template: "#show"
}
}
})
</script>
</body>
</html>
