显示用玉逗号分隔的数组？

Question

I want to display an array in Jade separated by commas instead of line which I currently have how can I do this? This is segment of code I need help with players being the array passed from javascript

p Currently playing:
  ul
    each theExit in players
      p #{theExit}

Answer 1

Assuming that players is an array of String 's you can use following statement:

p Currently playing: #{players.join(', ')}

That will give you something like (assuming you had 3 entries in the array: player1 , player2 and player3 ):

<p>Currently playing: player1, player2, player3</p>

I hope that will help.

Answer 2

Supposed you were working with not plain String arrays and your data is something like below:

{
  [_id: 1, name: 'player1'],
  [_id: 2, name: 'player2'],
  [_id: 3, name: 'player3'],
}

Then you could probably just use:

each player, index in players
  if index === players.length -1
    | #{players.name}
  else
    | #{players.name},

NOTE: Not really the cleanest solution out there but does the job. Use at your own disposal. :)

Answer 3

If you have an array of objects and you want a comma-separated list of a property of each object, I went with:

- var playerList = players.map(player => player.name).join(', ')
p Currently playing: #{playerList}
