使用AS3添加文本框編號

我已經有一段時間都在做這一切。我希望每個人都可以提供幫助。所以......這樣做的是拿出9個文本框號碼並將它們添加到動態文本框中。所以這是我的問題。使用AS3添加文本框編號

我該如何替換一個空的文本框與0，如果用戶擺脫已經在那裏的0，它會出來NaN。下面的if語句應該解決它，也許有人可以改進它。

 stage.addEventListener（Event.CHANGE，checkTotal）; nextQuestion_btn.addEventListener（MouseEvent.MOUSE_DOWN，nextQuestion）;
 function checkTotal(e:Event){ 

var work:Number = parseInt(work_txt.text); 
var rnr:Number = parseInt(rnr_txt.text); 
var exerciseB:Number = parseInt(exerciseB_txt.text); 
var exerciseM:Number = parseInt(exerciseM_txt.text); 
var chores:Number = parseInt(chores_txt.text); 
var social:Number = parseInt(social_txt.text); 
var food:Number = parseInt(food_txt.text); 
var twt:Number = parseInt(twt_txt.text); 
var partying:Number = parseInt(partying_txt.text); 
var other:Number = parseInt(other_txt.text);  

if(work_txt.text==""){ 
work=0; 
} 
if(rnr_txt.text==""){ 
rnr=0; 
} 
if(exerciseB_txt.text==""){ 
exerciseB=0; 
} 
if(exerciseM_txt.text==""){ 
exerciseM=0; 
} 
if(chores_txt.text==""){ 
chores=0; 
} 
if(social_txt.text==""){ 
social=0; 
} 
if(food_txt.text==""){ 
food=0; 
} 
if(twt_txt.text==""){ 
twt=0; 
} 
if(partying_txt.text==""){ 
partying=0; 
} 
if(other_txt.text==""){ 
other=0; 
} 

var total400:Number = work + rnr + exerciseB + exerciseM + 
chores + social + food + twt + partying + other;

  
  
  我不能讓我的文本框400加起來，從而將用戶在399到一個盒子，如果用戶鍵入2到下一個，目前的文本框會回到0，因爲它會超過400. 
 
 我被告知使用e.currentTarget可以解決這個問題，但我不知道如何使用它。
 我所有的代碼...這是我第一次在這個網站上，所以請原諒我的noobness。

rnr_txt.maxChars = 3;

如果值只能是int類型，嘗試使用int，而不是數

var work:int = parseInt(work_txt.text);//work will be 0 if the text is empty

如果你想恢復文本爲0（文本框中輸入其2）

function checkTotal(e:Event){ 

    var target:TextField = e.target as TextField; 

    if(total400 >= 400){ 

     if (target) {//you may check if target is one of the text box you have listed. 

      target.text = "0"; 

     } 

     nextQuestion_btn.visible=true; 
    } 
}
