Google Maps API 2.0解析(17-GSmallMapControl和GSmallZoomControl两个简单的控件)

        原来这俩个控件的代码这么简单

        //GSmallZoomControl控件
        function GSmallZoomControl()
        {
        }
        GSmallZoomControl.prototype=new GControl();
        GSmallZoomControl.prototype.initialize=function(a)
        {
            var b=new GSize(17,35);
            //创建控件层
            var c=CreateElement("div",a.getContainer(),null,b);
            //加载控件图片
            CreateImage(getStaticImageUrl("szc"),c,GPoint.ORIGIN,b,true);
            //创建图片上的可点击区域和触发的事件
            createClickArea(c,[[18,18,0,0,callback(a,a.zoomIn),_mZoomIn],[18,18,0,18,callback(a,a.zoomOut),_mZoomOut]]);
            return c
        };
        GSmallZoomControl.prototype.getDefaultPosition=function()
        {
            return new GControlPosition(0,new GSize(7,7))
        };
        //GSmallMapControl控件
        function GSmallMapControl()
        {
        }
        GSmallMapControl.prototype=new GControl();
        GSmallMapControl.prototype.initialize=function(a)
        {
            var b=new GSize(37,94);
            var c=CreateElement("div",a.getContainer(),null,b);
            //加载控件的图片，要注意的是，Google的控件是一个整体的图片
            CreateImage(getStaticImageUrl("smc"),c,GPoint.ORIGIN,b,true);
            createClickArea(c,[[18,18,9,0,GetCallback(a,a.panDirection,0,1),_mPanNorth],[18,18,0,18,GetCallback(a,a.panDirection,1,0),_mPanWest],[18,18,18,18,GetCallback(a,a.panDirection,-1,0),_mPanEast],[18,18,9,36,GetCallback(a,a.panDirection,0,-1),_mPanSouth],[18,18,9,57,GetCallback(a,a.zoomIn),_mZoomIn],[18,18,9,75,GetCallback(a,a.zoomOut),_mZoomOut]]);
            return c
        };
        GSmallMapControl.prototype.getDefaultPosition=function()
        {
            return new GControlPosition(0,new GSize(7,7))
        };
