在页面脚本中使用玉的迭代

Question

我需要将（json）对象插入到页面中使用的数组中。我用jade使用nodejs，并假设下面的代码可能符合我的目的，但它不起作用。

//this code is in the template: 
    script. 
     otherPlayers = {}; 
     each player in playerList 
      otherPlayers["#{player.playerId}"] = !{JSON.stringify(#{player})}; 

在页面预期的结果是：

<script> 
    otherPlayers = {}; 
    otherPlayers[0] = {"playerId": 0, "playerName": "Leo" }; 
    otherPlayers[1] = {"playerId": 1, "playerName": "Daniel" }; 
    otherPlayers[2] = {"playerId": 2, "playerName": "Lucas" }; 
</script> 

任何暗示被广泛接受。 在此先感谢。

您可以在模板文件中进行如下操作。

//In the template file 
script. 
    otherPlayers = {}; 
    var cplayerList = !{JSON.stringify(playerList)}; 
    for(player in cplayerList) { 
     otherPlayers[cplayerList[player].playerId] = cplayerList[player]; 
    } 
    console.log(otherPlayers);
