如何在函數中放置for循環？

Question

我正在嘗試創建一副沒有使用for循環的卡片。我得到的錯誤 「未捕獲的語法錯誤：線路189意外令牌」 線189是符合 「createcards」

var deck = { 
suit: suit = ["Diamond", "Heart", "Club", "Spade"], 
name: name = ["Nine", "Ten", "Jack", "Queen", "King", "Ace"], 
cards: cards = [], 
createcards: for (var i = 0; i < suit.length; i++){ 
     for (var j = 0; j < name.length; j++){ 
     deck.cards.push(card(name[j], suit[i])) 
    } 
}, 

draw: function (player){ 
    randnumber = Math.floor((Math.random() * cards.length)) 
    player.push[cards[randnumber]]; 

} 
}; 

Answer 1

設置cretaecards作爲一個匿名函數：

createcards: function(){ 
    for (var i = 0; i < deck.suit.length; i++){ 
      for (var j = 0; j < deck.name.length; j++){ 
      deck.cards.push(card(deck.name[j], deck.suit[i])) 
     } 
    } 
},

你必須在字面對象中定義一個函數。

var deck = { 
suit: suit = ["Diamond", "Heart", "Club", "Spade"], 
name: name = ["Nine", "Ten", "Jack", "Queen", "King", "Ace"], 
cards: cards = [], 
createcards: function() { 
    for (var i = 0; i < suit.length; i++) { 
     for (var j = 0; j < name.length; j++) { 
      deck.cards.push(card(name[j], suit[i])) 
     } 
    } 
} 
}, 

Answer 3

你應該分配給createcards一個匿名函數，像這樣：

createcards: function() { 
    for (var i = 0; i < suit.length; i++) { 
     for (var j = 0; j < name.length; j++) { 
      deck.cards.push(card(name[j], suit[i])); 
     } 
    } 
} 

Answer 4

使用功能，像這樣：

var deck = { 
suit: suit = ["Diamond", "Heart", "Club", "Spade"], 
name: name = ["Nine", "Ten", "Jack", "Queen", "King", "Ace"], 
cards: cards = [], 
createcards: 
    function() { 
     for (var i = 0; i < suit.length; i++){ 
      for (var j = 0; j < name.length; j++){ 
       deck.cards.push(card(name[j], suit[i])) 
      } 
     } 
    }, 
draw: function (player){ 
    randnumber = Math.floor((Math.random() * cards.length)) 
    player.push[cards[randnumber]]; 

} 

};

您可以調用該對象內部的功能是這樣的：

deck.createcards(); 

不過我建議你看看符合：

deck.cards.push(card(name[j], suit[i])) 

因爲沒有功能卡在這裏...
