1.下载插件

3.在标签上绑定点击事件

<div @click="handleFull">全屏/退出全屏</div>

4.在methods中写方法代码

handleFull() {if (screenfull.isEnabled) {// 加个判断浏览器是否支持全屏screenfull.toggle(); // 切换全屏状态} else {console.log("您的浏览器不支持全屏");}
}

页面全屏

5.在标签上绑定点击事件

<div id="demo" @click="container">指定元素全屏</div>

container() {const element = document.getElementById("demo"); // 指定全屏元素if (screenfull.isEnabled) {screenfull.request(element);this.elementFull = !this.elementFull; // 判断状态 决定是全屏还是退出全屏if (this.elementFull) {screenfull.toggle(); //全屏/退出全屏切换}}
