使用AS3添加文本框編號

Question

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。

1. 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; 
   

1. 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。

var total400:Number = work + rnr + exerciseB + exerciseM +

trace(exerciseM); 
trace(chores); 
trace(social); 
trace(food); 
trace(twt); 
trace(partying); 
trace(other); 
trace(total400); 

total400_txt.text = String(total400); 

    if(total400 >= 400){ 
     nextQuestion_btn.visible=true; 
    }else{ 
     nextQuestion_btn.visible=false; 
    } 
} 

Answer 1

Q1

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 

Q2

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; 
    } 
}
