Question

我试图创建单独的对象，因为我必须对它们执行类似的任务，我将它们推入一个数组。这样做似乎改变了对象的特定属性，我不知道为什么。我创建这样的对象：

var lo_ro = new PB.Edge(lo, ro);
var ro_ru = new PB.Edge(ro, ru);

代码段

console.log(lo_ro);
console.log("+");
console.log(ro_ru);
console.log("=");
console.log([lo_ro, ro_ru]);

返回了这个（在chrome中）：

console output

所以每个对象的所有者属性都变为“boardOwner” 这是我的Edge功能：

if (!window.PB)
    window.PB = {};
... 
PB.Edge = function (start, end) {
    this.start =  start.id; //Ids of vertecies
    this.end = end.id;
    this.owner = ""; 

    this.id = "(" + start.id + ")>(" + end.id + ")";
};
PB.Edge.boardOwner = "boardOwner";

“PB.Edge.boardOwner”用于其他用途，我不明白为什么所有者属性设置为“boardOwner”。

PS。这是一些更多的代码（评论是德语）：

(function () {

if (!window.PB)
    window.PB = {};

PB.Item = function (typ) {
    this.typ = typ;
    //weitere Feler typspezifisch
};

PB.GoalItem = function (playerID) {
    this.typ = "goal";
    this.player = playerID;
};

PB.Vertex = function (x, y) {
    this.x =  x; //ganzzahlen  auf karrierten papier!
    this.y = y;
    this.item = null;
    if (arguments.length > 2)
        this.item = arguments[2];
    this.id = x+"|"+y;
};
PB.Vertex.getID = function (x, y) {
    return x+"|"+y;
};

PB.Edge = function (start, end) {
    this.start =  start.id; //Ids of vertecies
    this.end = end.id;
    this.owner = ""; //kein owner heisst es edge ist initial edge einer zelle
                        //ansonsten  ID vom spieler
    this.id = "(" + start.id + ")>(" + end.id + ")";
};
PB.Edge.boardOwner = "boardOwner"; //Spielfeldrand
PB.Edge.getID = function (start, end) {
    return start.id + ">" + end.id;
};

PB.Cell = function (corners) {
    this.corners =  corners; //Array von Ids von Vertecies
    this.id = corners[0].id;
    for (var i = 1; i < corners.length; i+=1)
        this.id += ":"+corners[i].id;
};
PB.Cell.getID = function (corners) {
    var  id = corners[0].id;
    for (var i = 1; i < corners.length; i+=1)
        id += ":"+corners[i].id;
    return id;
};

PB.Board = function (vertecies, edges, cells, start, player, width,  height, type) {
    this.vertecies = vertecies; //bin Suchbäume
    this.edges = edges;
    this.cells =  cells;
    this.start = start; //id zu startvertex
    this.player = player; //array von ids von playern
    this.width = width;  //max x bzw y wert eines erhaltenen Vertex
    this.height = height;
    this.type = type;
};

})();
