vue实现视频全屏切换功能
作者：﹏ℳ๓₯㎕
这篇文章主要为大家详细介绍了如何使用vue实现视频全屏切换的功能,文中的示例代码讲解详细, 具有一定的借鉴价值,有需要的小伙伴可以参考一下
最近项目开发中遇到一个视频窗口全屏切换功能，为此在这里做个记录。
具体的实现思路：
<template>
<div class="content-box">
<div class="container">
<div id="screen" class="screen">
<el-button @click="screen()">
{{ fullscreen ? "还原" : "最大化" }}
</el-button>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
fullscreen: false,
};
},
mounted() {
window.addEventListener("resize", ()=> {
if (!this.isFullScreen()) {
// 非全屏状态
this.fullscreen = false;
}
});
},
methods: {
//判断是否全屏
isFullScreen() {
return !!(document.webkitIsFullScreen || this.fullele());
},
fullele() {
return (
document.fullscreenElement ||
document.webkitFullscreenElement ||
document.msFullscreenElement ||
document.mozFullScreenElement ||
null
);
},
screen() {
let element = document.getElementById("screen");
if (this.fullscreen) {
// 关闭全屏
if (document.exitFullscreen) {
document.exitFullscreen();
} else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
} else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if (document.msExitFullscreen) {
document.msExitFullscreen();
}
} else {
// 全屏
if (element.requestFullscreen) {
element.requestFullscreen();
} else if (element.webkitRequestFullScreen) {
element.webkitRequestFullScreen();
} else if (element.mozRequestFullScreen) {
element.mozRequestFullScreen();
} else if (element.msRequestFullscreen) {
// IE11
element.msRequestFullscreen();
}
}
this.fullscreen = !this.fullscreen;
},
},
};
</script>
<style lang="scss" scoped>
.screen {
width: 500px;
height: 500px;
background-color: #fff;
border: 1px solid red;
}
</style>这里需要监听ESC键，为此做了特殊处理，这里是Demo,跟使用效果图基本差不多
知识补充
除了实现视频全屏切换，vue还可以实现浏览器全屏以及退出全屏，下面是实现代码，希望对大家有所帮助
在src/utils/util.js中加入下面代码块
import Vue from 'vue'
const util = Vue.prototype.util = {}
// 切换全屏
util.fullScreen = function (element) {
element = element || document.body;
if (element.requestFullscreen) {
element.requestFullscreen();
} else if (element.mozRequestFullScreen) {
element.mozRequestFullScreen();
} else if (element.webkitRequestFullscreen) {
element.webkitRequestFullscreen();
} else if (element.msRequestFullscreen) {
element.msRequestFullscreen();
}
}
// 退出全屏
util.exitFullscreen = function () {
if (document.exitFullscreen) {
document.exitFullscreen();
} else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if (document.webkitExitFullscreen) {
document.webkitExitFullscreen();
}
}
export {
util
}
2.在页面中使用全屏/退出全屏
<template>
<div class="header">
<!-- 全屏 -->
<a v-if="fullScreenFlag" href="javascript:;" rel="external nofollow" rel="external nofollow" class="iconfont iconquanping" title="全屏" @click="fullScreen()"></a>
<!-- 退出全屏 -->
<a v-else href="javascript:;" rel="external nofollow" rel="external nofollow" class="iconfont icontuichuquanping1" title="退出全屏" @click="exitFullScreen()"></a>
</div>
</template>
<script>
export default {
data () {
return {
fullScreenFlag: true,
};
},
methods: {
// 全屏
fullScreen(){
this.fullScreenFlag = false;
this.util.fullScreen();
},
// 退出全屏
exitFullScreen() {
this.fullScreenFlag = true;
this.util.exitFullscreen();
},
},
};
