1.原生js实现
<template>
<div>
<div style="height:500px;500px; background:pink;" id="con_lf_top_div" @click="screen">
</div>
</div>
</template>
<script>
export default {
name: "home",
data() {
return {
//默认不全屏
fullscreen:false,
};
},
methods: {
screen(){
// let element = document.documentElement;//设置后就是我们平时的整个页面全屏效果
let element = document.getElementById('con_lf_top_div');//设置后就是 id==con_lf_top_div 的容器全屏
if (this.fullscreen) {
if (document.exitFullscreen) {
document.exitFullscreen();
} else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
} else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if (document.msExitFullscreen) {
document.msExitFullscreen();
}
} else {
if (element.requestFullscreen) {
element.requestFullscreen();
} else if (element.webkitRequestFullScreen) {
element.webkitRequestFullScreen();
} else if (element.mozRequestFullScreen) {
element.mozRequestFullScreen();
} else if (element.msRequestFullscreen) {
element.msRequestFullscreen();
}
}
this.fullscreen = !this.fullscreen;
}
}
};
</script>
2.插件 screenfull实现
npm install screenfull@4.2.0 --save
<template>
<div>
<a-button type="primary" @click="screen">全屏</a-button>
</div>
</template>
<script>
import screenfull from "screenfull";
export default {
name: "home",
data() {
return {
//默认不全屏
isFullscreen: false
};
},
methods: {
screen() {
// 如果不允许进入全屏，发出不允许提示
if (!screenfull.enabled) {
this.$message("您的浏览器不能全屏");
return false;
}
screenfull.toggle();
this.$message.success("全屏啦");
}
}
};
</script>
