Question

发送的数据是Ruby格式：

mob = {id: 1, xpos:100, ypos:150, xposDest:150, yposDest:100, attacked:0}
WebsocketRails[:channel_name].trigger(:event_name, mob)

我怎么能让这个循环更简单？（这是coffeescript）

  get_all_mobs: (mob) ->  // getting "mob" with Websockets
    mob_list[mob.id].id = mob.id
    mob_list[mob.id].xpos = mob.xpos if mob.xpos?
    mob_list[mob.id].ypos = mob.ypos if mob.ypos?
    mob_list[mob.id].xposDest = mob.xposDest if mob.xposDest?
    mob_list[mob.id].yposDest = mob.yposDest if mob.yposDest?
    mob_list[mob.id].health = mob.health if mob.health?
    mob_list[mob.id].level = mob.level if mob.level?
    mob_list[mob.id].max_health = mob.max_health if mob.max_health?
    mob_list[mob.id].attacked = mob.attacked if mob.attacked?
    mob_list[mob.id].steps = mob.steps if mob.steps?

尝试了类似的东西，但错了：

get_all_mobs: (mob) ->  // getting "mob" with Websockets
  for attribute in mob
    mob_list[mob.id].attribute = mob.attribute

Answer 1

这应该做：

get_all_mobs: (mob) ->  // getting "mob" with Websockets
  for own key, value of mob
    mob_list[mob.id][key] = value if value?

Coffeescript循环简化
