js物件內部存取this修飾的成員函數範例_基礎知識

用wrapper封裝這樣在物件內外都可以存取

複製程式碼 程式碼如下:

function MapPool(){

 function createMarker(name, lat, lng, state){
  var marker = new AMap.Marker({
   position : new AMap ); >  //the function mapMoveTo is not accessible here too
        AMap.event.addListener(marker, "click",function(e){  this.moveMapTo(key, name, state) will raise a unresolved function error
   //you should write wrapper function as a member variable
      });
 }

 var _mapMoveTo = function(key, name, state){
  //TODO
 }

 this.mapMTo== 🎜>  _mapMoveTo(key, name, state);
 }
}
