significance
Vue is highly respected by the majority of front-ends. It is very important that component encapsulation, but when component encapsulation,Components may be used everywhere, but the styles may be different everywhere, for example: button components, What to do at this time, is it that components with different styles but the same structure are encapsulated multiple times? Obviously it is very uneconomical.
Speak with code
Parent component:
<template>
<el-container class="layout_container">
<el-header height="auto"><header-top></header-top></el-header>
<el-container>
<el-aside width="auto"><aside-left></aside-left></el-aside>
<el-main>
<zonghe-nengli></zonghe-nengli>
/重点看此处：
<my-button
:title="biaoti"
:color="activeColor"
:size="fontSize"
></my-button>
///
<skill-hot></skill-hot>
<learning-path></learning-path>
<bar-chart></bar-chart>
<radar></radar>
<tupu-fenxi></tupu-fenxi>
</el-main>
</el-container>
</el-container>
</template>
<script>
import HeaderTop from "../../components/layout/header";
import MyButton from "../../components/common/button";
import AsideLeft from "../../components/layout/aside";
import ZongheNengli from "../../components/common/zonghenengli";
import Radar from "../../components/common/radar";
import TupuFenxi from "../../components/common/tupufenxi";
import SkillHot from "../../components/putong/skillhot";
import LearningPath from "../../components/putong/learningpath";
import BarChart from "../../components/common/barchart";
export default {
components: {
HeaderTop,
AsideLeft,
ZongheNengli,
Radar,
TupuFenxi,
SkillHot,
LearningPath,
BarChart,
MyButton,
},
data() {
return {
///
biaoti: 20,
activeColor: "black",
fontSize: 30,
///
};
},
created() {
},
methods: {
},
computed: {
},
};
</script>
<style scoped>
.layout_container {
height: 100%;
}
.el-aside {
margin-top: 21px;
background: #ffffff;
box-shadow: 0px 1px 13px 0px rgba(0, 0, 0, 0.35);
}
.el-main {
margin-top: 40px;
margin-left: 37px;
background-color: burlywood;
}
</style>
Sub-components (emphasis on):
<template>
<div class="button_container" :style="{color:activeColor,fontSize:fontSize + 'px'}">
{
{
title }}
</div>
</template>
<script>
export default {
/接受传过来的参数
props: ["title","color","size"],
data() {
return {
activeColor: this.color,
fontSize: this.size,
};
},
created() {
},
methods: {
},
computed: {
},
};
</script>
<style scoped>
.button_container {
width: 207px;
height: 60px;
margin: 35px;
line-height: 60px;
text-align: center;
background: #2e5afb;
box-shadow: 3px 8px 17px 1px rgba(46, 90, 251, 0.6);
border-radius: 6px;
}
</style>
Effect picture:
If you want to encapsulate a component that can dynamically change the style, you must master the class and style binding of the vue component, so that you can do it with ease
