复制代码 代码如下:

ClassModel =
{
    create : function()
     {
        return function()
        {
            this.construct.apply(this, arguments);
        }
     }
}
Extend = function(desc, src)
    {
        for(var c in src)
        {
            desc[c] = src[c];
        }
        return desc;
    }
Object.prototype.extend = function(src)
    {
        return Extend.apply(this, [this, src]);
    }
