考虑以下代码:
function Coord(x, y) {
this.x = x;
this.y = y;
}
function Ellipse() {
this.Text = Text;
this.Cx = Cx;
this.Cy = Cy;
this.Rx = Rx;
this.Ry = Ry;
}
现在在函数中Ellipse
而不是 usingCx
等Cy
。我想Coord
为每一对实例化函数以实现如下所示:
function Coord(x, y) {
this.x = x;
this.y = y;
}
function Ellipse() {
this.Text = Text;
Coord C = new C(); // where C has its own properties x and y
Coord R = new R(); // where R has its own properties x and y
}
