OLD BAD.....
Hey i think there is a sytax error on your code. At the place you decline the onload event for the map you say use the function "theMap" but it isn't declared. Try to use a debugging tool like firebug for FF.

IGNORE UPPER
OK I'm wrong first day after holiday 🙂 .... the js isn't correct but it seems that LOD's of the maps doesn't match. As example the WaterTemplate has a scale of 800 but the PublicSafety has no LOD with a scale of 800. If you have cached maps must have same scales or they can't displayed together

According to me there is problem in the code and I think <div> tag are mismatching..Please paste your code in JS Fiddle

Hi Yan,

The map services are in different geographic areas. So, after you click the drop down button to show the other map service you will need to update the extent using the setExtent method. Ex:

function createdropbutton()
      {
         var splitbutoon=new Ext.button.Split({
             renderTo: "extSlider",
             frame:true,
             text:'�??换',
             menu:new Ext.menu.Menu({
                 items: [
            // these will render as dropdown menu items when the arrow is clicked:
            {text: '影�?�', handler: function(){
               // alert("Item 1 clicked");basemapGallery.select("basemap_0");}
                    Dbasemap1.setVisibility(true); 
                    Ybasemap.setVisibility(false);
                    var originalExtent = new esri.geometry.Extent({"xmin":-86.309,"ymin":37.895,"xmax":-85.044,"ymax":38.515,"spatialReference":{"wkid":4326}});
                    map.setExtent(originalExtent);  
               }
            },
            {text: '�?�形', handler: function(){
              //alert("Item 2 clicked");basemapGallery.select("basemap_1"); }
                    Dbasemap1.setVisibility(false); 
                    Ybasemap.setVisibility(true);
                    var newExtent = new esri.geometry.Extent({"xmin":-80.466,"ymin":27.287,"xmax":-80.248,"ymax":27.536,"spatialReference":{"wkid":4326}});
                    map.setExtent(newExtent);
                        }
            }
                ]
             })
          });
