我正在定义一个这样的对象:

function Project(Attributes, ProjectWidth, ProjectHeight)
{
    this.ProjectHeight = ProjectHeight;
    this.ProjectWidth = ProjectWidth;
    this.ProjectScale = this.GetProjectScale();
    this.Attributes = Attributes;

    this.currentLayout = '';

    this.CreateLayoutArray = function()
    {....}
}

然后我尝试创建和实例像这样:

var newProj = new Project(a,b,c);

但是这个例子被抛出:

Project is not a constructor

可能有什么不对？我搜索了很多,但仍然无法弄清楚我做错了什么.
