1、项目中使用的是sreenfull插件,执行命令安装
npm install --save screenfull
2、安装好后,引入项目,用一个按钮进行控制即可,按钮方法如下:
toggleFullscreen() { if (!screenfull.enabled) { this.$message({ message: 'you browser can not work', type: 'warning' }) return false } screenfull.toggle() }
试了一下可以全屏,我用的chrome,IE9以下不要考虑
3、第一步完成之后就是怎么监听到全屏的变化,因为如果是通过Esc键退出全屏,此时是没办法监听到的。经过一番查找,解决办法如下:
<script> import screenfull from 'screenfull' export default { data () { return { isFullscreen: false } }, methods: { /** * 全屏事件 */ screenfull() { if (!screenfull.enabled) { this.$message({ message: 'Your browser does not work', type: 'warning' }) return false } screenfull.toggle() this.isFullscreen = true }, /** * 是否全屏并按键ESC键的方法 */ checkFull() { var isFull = document.fullscreenEnabled || window.fullScreen || document.webkitIsFullScreen || document.msFullscreenEnabled // to fix : false || undefined == undefined if (isFull === undefined) { isFull = false } return isFull } }, mounted() { window.onresize = () => { // 全屏下监控是否按键了ESC if (!this.checkFull()) { // 全屏下按键esc后要执行的动作 this.isFullscreen = false } } } } </script>
