Question

对于冗长的标题，我很抱歉，但我无法想出更好的描述。问题在于：我在游戏中定义了一些太空飞船，为此我创建了一个包含所有数据（盾牌等）的简单表格：

var defaultShipDataSheet = [
['Shields',             DISPLAY_HANGAR,    DISPLAY_HUD, { id:  0, core: 100, base: 100, mod: 100 }], 
['Armor',               DISPLAY_HANGAR,    DISPLAY_HUD, { id:  1, core: 100, base: 100, mod: 100 }],
['Toughness',        NO_DISPLAY_HANGAR, NO_DISPLAY_HUD, { id:  2, core: 100, base: 100, mod: 100 }],  
['Speed',               DISPLAY_HANGAR,    DISPLAY_HUD, { id:  3, core: 100, base: 100, mod: 100 }], 
['Weight',              DISPLAY_HANGAR,    DISPLAY_HUD, { id:  4, core: 100, base: 100, mod: 100 }],       
['Agility',             DISPLAY_HANGAR, NO_DISPLAY_HUD, { id:  5, core: 100, base: 100, mod: 100 }],
['Area Damage',         DISPLAY_HANGAR, NO_DISPLAY_HUD, { id:  6, core: 100, base: 100, mod: 100 }],
['Life On Hit',         DISPLAY_HANGAR, NO_DISPLAY_HUD, { id:  7, core: 100, base: 100, mod: 100 }],
['Life On Kill',        DISPLAY_HANGAR, NO_DISPLAY_HUD, { id:  8, core: 100, base: 100, mod: 100 }],  
['Firing Rate',         DISPLAY_HANGAR, NO_DISPLAY_HUD, { id:  9, core: 100, base: 100, mod: 100 }],   
['Beam Charging Time',  DISPLAY_HANGAR, NO_DISPLAY_HUD, { id: 10, core: 100, base: 100, mod: 100 }],
['Bomb Capacity',       DISPLAY_HANGAR,    DISPLAY_HUD, { id: 11, core: 100, base: 100, mod: 100 }],
['Critical Hit Chance', DISPLAY_HANGAR, NO_DISPLAY_HUD, { id: 12, core: 100, base: 100, mod: 100 }],
['Critical Damage',     DISPLAY_HANGAR, NO_DISPLAY_HUD, { id: 13, core: 100, base: 100, mod: 100 }],
['Damage',              DISPLAY_HANGAR, NO_DISPLAY_HUD, { id: 14, core: 100, base: 100, mod: 100 }],
];

创建没有标签和显示选项的缩小版本后：

var defaultShipData = {};
for (var m=0; m <= defaultShipDataSheet.length-1; m++) {
    propertyName = defaultShipDataSheet[m][0].substr(0, 1).toLowerCase() + defaultShipDataSheet[m][0].substr(1);
    propertyName = propertyName.replace(/ /g, "");
    defaultShipData[propertyName] = defaultShipDataSheet[m][3];
}

然后我宣布让我们说几艘船：

var allShips = [

{   id:                 0,
    name:               'Sparrow',
    country:            'US',
    code:               'LT-21',
    shipData:           defaultShipData,
    spriteSheet:        'lt21.json',
    weaponGrid:         defaultWeaponGrid },

{   id:                 1,
    name:               'Industrial Posterites',
    country:            'US',
    code:               'INPO-715',
    shipData :          defaultShipData,
    spriteSheet:        'lt21.json',
    weaponGrid:         defaultWeaponGrid }]

然后我覆盖定制船的值：

/* Industrial Posterites */
allShips[1].shipData.shields.core = 20;

然后将其分配给整个范围的船舶（以及相关的defaultShipData对象）。这是对defaultShipData对象的捕获：

我想这是因为它全部通过引用传递，但是我该如何避免这种情况？

我看过克隆方法，但我不确定它是否是正确的方法。

分配给变量的对象作为默认值并被覆盖不能按预期工作
