Jquery ajax在Chrome中發回多個響應，而在FF中只發送一個響應

Question

問題是，如果有新消息，而不是隻發出一次警報，Chrome會以相同的值警告5-8次。相反，這些代碼適用於FF，它只警告一次。我如何修復代碼以支持Chrome。 HTML：

setInterval(function() { 
    $.get('/restaurant/get_msg_notification',{},function(data){ 
     alert(data) 
    }) 
}, 1000) 

查看：

def get_msg_notification(request):  
    while True: 
     # check is there any new messages ? 
     msg = Message.objects.filter(receiver = user, notify = False) 
     if(len(msg)==0 and patient<5): 
      time.sleep(5) 
      patient+=1 
     else: 
      break 
    if(len(msg) > 0): 
     data = serializers.serialize('json', msg) 
     msg.update(notify = True) 
     return HttpResponse(data, mimetype="application/json") 
    else: 
     return HttpResponse("")

事實上，火狐似乎是不正常的人。請嘗試使用以下代碼代替：

def get_msg_notification(request):  
    while True: 
     # check is there any new messages ? 
     msg = Message.objects.filter(receiver = user, notify = False) 
     if(patient < 5): 
      time.sleep(5) 
      patient+=1 
     else: 
      if (len(msg) != 0): 
       msg.update(notify = True) 
      break 

    data = serializers.serialize('json', msg) 
    return HttpResponse(data, mimetype="application/json")
