Promise 采坑计

1. 初始化-获取循环中的异步数据

// 初始化
    onLoadPage(info: any, dept: any = null, newInfo: any = null) {
        if (info && info.ID) {
            this._service.getEdit(info.ID).success((d) => {
                $.extend(this.editInfo, d);
                    // 查询岗位列表
                    if (this.editInfo.Positions.length > 0) {
                        const unitPositions = [];
                        Promise.all(
                              //  添加 async 和 await
                            this.editInfo.Positions.map(async (o) => {
                                let dept;
                                if (o && o.UnitID) {
                                    await this.loadNode(o.UnitID).then((data) => {
                                        dept = data.find((d) => d.id === o.DeptID);
                                    });
                                }
                                return dept ? this.pushPosition(unitPositions, dept, o) : Promise.resolve();
                            })
                        ).then((d) => {
                            this.editInfo.Positions = unitPositions;
                        });
                    }
                });
            });
    }
    /**
     * 职位

     */
    pushPosition(positionUsers: any[], dept: any, positionUser: any = null) { }
