load Baidu map, click A, create a div, on Baidu map and drag A point to the map?

I thought it was the layer problem, but I changed the layer, but it didn"t work. Ladies and Gods, take a look.

![var pt = new BMap.Point(data\[i\].longitude,data\[i\].latitude);
var myIcon = new BMap.Icon("${ctxPath}/static/img/.png", new BMap.Size(100,50));
var modemData = data\[i\];
//
                    var opts = {
                                      width : 100,     // 
                                      height: 50,     // 
                                      title : data\[i\].siteName, // 
                                    };

var infoWindow = new BMap.InfoWindow(data\[i\].ip, opts);  //  
addMarker(pt,opts,myIcon,infoWindow,modemData);

var marker = new BMap.Marker(point,{icon:myIcon});

marker.enableDragging();][1]
