用wrapper封装这样在对象内外都可以访问

复制代码 代码如下:

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);

}

}
