js对象内部访问this修饰的成员函数示例

　　function MapPool(){

　　function createMarker(name, lat, lng, state){

　　var marker = new AMap.Marker({

　　position : new AMap.LngLat(lng, lat),

　　});

　　//the function mapMoveTo is not accessible here too

　　AMap.event.addListener(marker, "click",function(e){

　　//moveMapTo(key, name, state)

　　//or this.moveMapTo(key, name, state) will raise a unresolved function error

　　//you should write wrapper function as a member variable

　　_mapMoveTo(key, name, state);

　　});

　　}

　　var _mapMoveTo = function(key, name, state){

　　//TODO

　　}

　　this.mapMoveTo = function(key, name, state) {

　　_mapMoveTo(key, name, state);

　　}

　　}
