如何在javascript中總結兩個不同的功能

Question

我想總結兩個功能，它們是同一個對象的一部分。

var player = { 
stats: 0, 
level: 1, 
inventory: 30, 
baseStrength: 5, 
weaponStrength: 0, 
armorStrength: 0, 
accessoryStrength: 0, 
totalStrength: function() { 
    return (player.baseStrength + player.weaponStrength + player.armorStrength + player.accessoryStrength); 
}, 
baseEndurance: 5, 
weaponEndurance: 0, 
armorEndurance: 0, 
accessoryEndurance: 0, 
totalEndurance: function() { 
    return (player.baseEndurance + player.weaponEndurance + player.armorEndurance + player.accessoryEndurance); 
}, 
baseAgility: 5, 
weaponAgility: 0, 
armorAgility: 0, 
accessoryAgility: 0, 
totalAgility: function() { 
    return (player.baseAgility + player.weaponAgility + player.armorAgility + player.accessoryAgility); 
}, 
baseDexterity: 5, 
weaponDexterity: 0, 
armorDexterity: 0, 
accessoryDexterity: 0, 
totalDexterity: function() { 
    return (player.baseDexterity + player.weaponDexterity + player.armorDexterity + player.accessoryDexterity); 
}, 
baseIntelligence: 5, 
weaponIntelligence: 0, 
armorIntelligence: 0, 
accessoryIntelligence: 0, 
totalIntelligence: function() { 
    return (player.baseIntelligence + player.weaponIntelligence + player.armorIntelligence + player.accessoryIntelligence); 
}, 
baseWisdom: 5, 
weaponWisdom: 0, 
armorWisdom: 0, 
accessoryWisdom: 0, 
totalWisdom: function() { 
    return (player.baseWisdom + player.weaponWisdom + player.armorWisdom + player.accessoryWisdom); 
}, 
baseLuck: 5, 
weaponLuck: 0, 
armorLuck: 0, 
accessoryLuck: 0, 
totalLuck: function() { 
    return (player.baseLuck + player.weaponLuck + player.armorLuck + player.accessoryLuck); 
}, 
experience: 0, 
maxexperience: 100, 
gold: 0, 
health: 50, 
maxhealth: function() { 
    return ((player.baseEndurance + player.weaponEndurance + player.armorEndurance + player.accessoryEndurance) * 10); 
}, 
mana: 50, 
maxMana: function() { 
    return (player.totalWisdom * 10 + player.totalIntelligence * 5); 
}, 
manaRegen: function() { 
    return (player.totalWisdom); 
}, 
mindamage: function() { 
    return Math.floor((player.totalStrength * 0.5)); 
}, 
maxdamage: function() { 
    return (player.totalStrength * 0.8); 
}, 
hpregen: function() { 
    return Math.floor((player.totalEndurance)); 
}, 
accuracy: function() { 
    return Math.floor((95 + (player.totalAgility * 0.05 + player.totalLuck * 0.1))); 
}, 
defense: function() { 
    return (player.totalDexterity * 1.2 + player.totalEndurance * 0.5); 
}, 
evasion: function() { 
    return (5 + (player.totalAgility * 0.5 + player.totalLuck * 0.15)); 
}, 
criticalChance: function() { 
    return (player.totalAgility * 0.5 + player.totalLuck * 0.5); 
}, 
criticalDamage: function() { 
    return (player.totalStrength * 0.1 + player.totalDexterity * 0.1); 
}, 
Lifesteal: function() { 
    return (player.totalIntelligence/100); 
}, 
Lifesteal2: function() { 
    return (player.totalIntelligence); 
}, 
dropRate: 0, 
expRate: 0 
}; 

好了，你可以看到，我會爲每個統計，基地/武器/防具/附件/共5個對象屬性。總計是對所有這些統計數據進行總結的函數。

之後，我們有玩家最大健康，也是功能，這是使用「總」統計計算的功能，但因爲它也是一個功能，我不能使它的工作。所以我想出的唯一辦法，是不是 (player.totalEndurance * 10)

我要做((player.baseEndurance + player.weaponEndurance + player.armorEndurance + player.accessoryEndurance) * 10)

和部分在那裏我的HTML顯示它：

​​

我加（），因爲它的一個函數，但它不工作我得到NaN結果，函數要麼是未定義的，要麼或「對象不是函數」錯誤。

我希望你能幫助我:)謝謝

Answer 1

第2部分（最終）：

要計算使用totalEndurance需要括號添加到您的電話，因爲它是一個功能。

player.totalEndurance() 

第1部分（前評論）：

我認爲有些事情可能會在你的問題中丟失。

當我把您的播放器變量中的jsfiddle，然後執行
