1. 安装
npm install screenfull --save
这个指令安装最新版本
npm install screenfull@3
VUE2.x的可以指定对应的版本，这样是安装最新的3.x的版本
2. 导入svg文件
在src\icons\svg文件夹下，导入exit-fullscreen.svg和fullscreen.svg,
exit-fullscreen.svg，新建这个文件再将以下代码复制到这个文件就OK了

<template>
<div>
<svg-icon :icon-class="isFullscreen?'exit-fullscreen':'fullscreen'" @click="click" />
</div>
</template>
<script>
import screenfull from 'screenfull'
export default {
name: 'Screenfull',
data() {
return {
isFullscreen: false
}
},
mounted() {
this.init()
},
beforeDestroy() {
this.destroy()
},
methods: {
click() {
if (!screenfull.enabled) {
this.$message({
message: 'you browser can not work',
type: 'warning'
})
return false
}
screenfull.toggle()
},
change() {
this.isFullscreen = screenfull.isFullscreen
},
init() {
if (screenfull.enabled) {
screenfull.on('change', this.change)
}
},
destroy() {
if (screenfull.enabled) {
screenfull.off('change', this.change)
}
}
}
}
</script>
<style scoped>
.screenfull-svg {
display: inline-block;
cursor: pointer;
fill: #5a5e66;;
width: 20px;
height: 20px;
vertical-align: 10px;
}
</style>
4.然后进入src/layout/components/Navbar.vue，script脚本中进入组件
5.引用screenfull组件
<template v-if="device!=='mobile'">
<screenfull id="screenfull" class="right-menu-item hover-effect" />
</template>以上步骤就可以将全屏放大缩小的按钮加到框架了，效果显示：
