vue如何实现视频全屏切换-CSDN博客

        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
