vue中如何做全屏跟全局时间过滤器

首先我们在template写一些标签

 <div class="Full-screen" @click="addScreen">
           <el-tooltip effect="dark" :content="fullscreen ? `取消全屏`:`全屏`" placement="bottom">
              <i class="el-icon-rank"></i>
           </el-tooltip>
</div>

script data中定义一个变量

data(){
return {
fullscreen: false
}
}  

然后在methods中写一个函数

// 全屏事件
            addScreen(){
                let element = document.documentElement;
                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) {
                        // IE11
                        element.msRequestFullscreen();
                    }
                }
                this.fullscreen = !this.fullscreen;
}

Vue中全局时间过滤器操作如下：

首先在main.js中写

//时间过滤器
Vue.filter('dataFormat', originVal => {
  const dt = new Date(originVal)
  const y = dt.getFullYear()
  const m = (dt.getMonth() + 1 + '').padStart(2, '0')
  const d = (dt.getDate() + '').padStart(2, '0')
  const hh = (dt.getHours() + '').padStart(2, '0')
  const mm = (dt.getMinutes() + '').padStart(2, '0')
  const ss = (dt.getSeconds() + '').padStart(2, '0')
  return `${y}-${m}-${d} ${hh}:${mm}:${ss}`
})

然后在组件中使用的话只需要在你要过滤的时间后面加管道符（|dataFormat）就ok了
