Possible iteration over unexpected (custom / inherited) members, probably missing hasOwnProperty che

webStorm编辑器中报警告：Possible iteration over unexpected (custom / inherited) members, probably missing hasOwnProperty check

问题：没有hasOwnProperty验证

解决：添加 hasOwnProperty 验证

for (var key in res.data.missing) {
  if (res.data.missing.hasOwnProperty(key)) {
    const element = res.data.missing[key]
    if (element != null) {
      unfinished.push({
        vol: key,
        timeInterval: element
      })
    }
  }
}
