[JaneYork]

示例代码

      this.player = new Aliplayer(props, (player) => {
        console.log('播放器初始化完成', player)
        // 添加截图事件监听器
        player.on('snapshoted', (data) => {
          console.log('截图完成', data)
          this.handleSnapshot(data)
        })
      })
    handleSnapshot(data) {
      // 处理截图数据，可以将数据保存到组件的变量中
      console.log('截图完成', data)
      var pictureData = data.paramData.base64
      var downloadElement = document.createElement('a')
      downloadElement.setAttribute('href', pictureData)
      var fileName = 'Aliplayer' + Date.now() + '.png'
      downloadElement.setAttribute('download', fileName)
      downloadElement.click()
      pictureData = null
      // 执行其他操作...
    },
