我正在编写一些用于编写 Adob​​e Illustrator 脚本的辅助类。

我的问题始于 Eyelet 对象。当我实例化它时,它一开始就失败了,new Group()因为显然Group没有构造函数。

这是我的代码的精简版本:

/****************** Collection Class **********************/

function Collection() {
    this.parent = app.activeDocument;
    this.typename = "Collection";
}

    Collection.prototype.setName = function(name) {
        this.instance.name = name;
    };

/****************** Group (extends collection) *****************/

function Group(name, parent) {
    this.parent = parent || this.parent;
    this.instance = this.parent.groupItems.add();
    if(name) {
        this.setName(name);
    } else {
        this.setName("Group");
    }
}

Group.prototype = new Collection();

/****************** Shape Class **********************/

function Shape() {
    this.parent = app.activeDocument;
    this.typename = "Shape";
}

Shape.prototype.setName = function(name) {
        this.instance.name = name;
    };

Shape.prototype.stroke = function(width, color) {
        this.instance.stroked = true;
        this.instance.strokeWeight = width;
        this.instance.strokeColor = color;
    };

/****************** Line (extends Shape) **********************/

function Line(parent, start, end) {

    this.instance = parent.pathItems.add();
    // [ [startX, startY], [endX, endY] ]
    this.instance.setEntirePath([start,end]);

}

Line.prototype = new Shape();

/****************** Eyelet (extends Shape) **********************/

function Eyelet(parent, position) {
    this.instance = new Group("Eyelet", parent);
    var whiteCross = new Group("White", this.instance);
    var blackCross = new Group("Black", this.instance);

    var build = function(group, color, width) {
        var vertical = new Line( group , [0 , 0] , [0 , 50] );
        vertical.setName("vertical");
        vertical.stroke(width, color);
        var horizontal = new Line( group , [0 , 50] , [50 , 0] );
        horizontal.setName("horizontal");
        horizontal.stroke(width, color);
    };

    build(whiteCross.instance, white, (3 * scale) );
    build(blackCross.instance, black, (1 * scale) );

    this.instance.position = position;

}

Eyelet.prototype = new Shape();

当我写

var eyelet = new Eyelet(layer2, [10,10]);

我明白了

组没有构造函数

我已经通过 jslint 运行了这段代码,但我不明白为什么这不起作用。任何帮助将非常感激。

事实证明,这在 Adob​​e Illustrator中是相关的。我将Group对象重命名MyGroup为 Dan Breslau 建议的那样,它按我的预期工作。似乎 Illustrator 有一个Group导致问题的全局对象。谢谢你的帮助。
