await setTimeout(async() => {

这样使用前端ajax就可以不用延迟获取截图

function sleep (ms) {
  return new Promise((resolve, reject) => {
    console.log('睡眠开始')
    setTimeout(() => {
      console.log('睡眠结束')
      resolve()
    }, ms)
  })
}
iJump = async (distance) => {
  await jumpGo(parseInt(distance * BOOM))
  await sleep(500)
  await fetchScreenCap()
  console.log('截图完成...')
}
