TypeScript之Map的遍历

        let $cell : BeeCreateVo = null;        let $find : BeeCreateVo = null;        this._hash_map.forEach( ( $arr : Array , $key : TY_SoldierContainer , $map : any ) : void => {            if( $arr && $arr.length > 0 ){                for( let $i : number = 0 , $j : number = $arr.length ; $i < $j ; $i ++ ){                    $cell = $arr[$i];                    if( $cell.soldier_id == $id ){                        $find = $cell;                        break;                    }                }            }        } );

PS :
$arr : 既是Map的value
$key : 既是Map的key

注意 forEach里面不能return , 所以 :

    public getSoliderById( $id : number , $isDeepCopy : boolean = false ) : BeeCreateVo{        let $cell : BeeCreateVo = null;        let $find : BeeCreateVo = null;        this._hash_map.forEach( ( $arr : Array , $key : TY_SoldierContainer , $map : any ) : void => {            if( $arr && $arr.length > 0 ){                for( let $i : number = 0 , $j : number = $arr.length ; $i < $j ; $i ++ ){                    $cell = $arr[$i];                    if( $cell.soldier_id == $id ){                        $find = $cell;                        break;                    }                }            }        } );        if( $find ){            if( !$isDeepCopy ){                return $find;            }else{                return {                    id : $find.id,                    soldier_id : $find.soldier_id,                    soldier_num : $find.soldier_num,                    soldier_used_num : $find.soldier_used_num,                    technology_level : $find.technology_level,                    time_out : $find.time_out,                    status_code : $find.time_out                }            }        }        return null;    }
