Question

我有一个函数，我在其中调用两个函数，我想完全运行第一个函数然后第二个执行但我无法控制它。

DayCalendar: function(ProviderId, ResourceId, FacilityId, CriteriaDate, statusid) {
    MDVisionService.lookups("GetAppointmentStatus").done(function(result) {
        appstatus = result;
    });
    Scheduling_Calendar.SearchDaySlotSchedule(ProviderId, ResourceId, FacilityId, CriteriaDate, statusid).done(function (response) {
        if (response.status != false) {
        }
    });
}

Answer 1

将第二个函数Scheduling_Calendar.SearchDaySlotSchedule移动到第一个函数MDVisionService.lookups的回调

DayCalendar: function(ProviderId, ResourceId, FacilityId, CriteriaDate, statusid) {
    MDVisionService.lookups("GetAppointmentStatus").done(function(result) {
        appstatus = result;
        Scheduling_Calendar.SearchDaySlotSchedule(ProviderId, ResourceId, FacilityId, CriteriaDate, statusid).done(function (response) {
            if (response.status != false) {
            }
        });
    });
}

Answer 2

我会写一些类似的东西：

DayCalendar: function(ProviderId, ResourceId, FacilityId, CriteriaDate, statusid, callback) {
MDVisionService.lookups("GetAppointmentStatus").done(function(result) {
    appstatus = result;
    //callback(arguments) //if you need to call it here
}); 
callback(arguments);
}

schedule: function(ProviderId, ResourceId, FacilityId, CriteriaDate, statusid){
 var args = arguments;
 return function() { 
   return Scheduling_Calendar.SearchDaySlotSchedulea.apply(this, args).done(function (response) {
    if (response.status != false) {
    }
   });
 } 

//call
DayCalendar(ProviderId, ResourceId, FacilityId, CriteriaDate, statusid, schedule());

两个js函数一个接一个地执行？
