在 Flash (AS3) 中动态填充文本字段

Question

我正在尝试弄清楚如何在 Flash 中动态填充文本字段。根据 bstatus 的值，字段中的文本将显示 ON 或 OFF。

var bstatus 的值为 0 或 1

我有下面列出的文本字段。 我不确定语法是否正确，但我认为文本字段将位于一个数组中，并且我将创建一个 for 循环——它将遍历该数组以便填充字段。

   var textFields:Array = new Array();
   textFields[0] = compTxt.text;
   textFields[1] = bathLightTxt.text;
   textFields[2] = computerLightTxt.text;
   textFields[3] = kitchenLight.text;
   textFields[4] = livingLightTxt.text;
   textFields[5] = descLightTxt.text;
   textFields[6] = laundryLightTxt.text;
   textFields[3] = ovenTxt.text;
   textFields[8] = tvTxt.text; 
   textFields[9] = washerTxt.text; 

我认为 textFields 数组将进入名为 populateFields() 的函数内部

 // function populateFields ------------------------------------------------------------------
  function populateFields(bstatus:int)
{

   var displayText:String="";   

   var textFields:Array = new Array();
   textFields[0] = compTxt.text;
   textFields[1] = bathLightTxt.text;
   textFields[2] = computerLightTxt.text;
   textFields[3] = kitchenLight.text;
   textFields[4] = livingLightTxt.text;
   textFields[5] = descLightTxt.text;
   textFields[6] = laundryLightTxt.text;
   textFields[3] = ovenTxt.text;
   textFields[8] = tvTxt.text; 
   textFields[9] = washerTxt.text; 


  if (bstatus == 0) {
   // textfield will say OFF
          displayText = "OFF";

  } else if (bstatus == 1) {
  // textfield will say ON
            displayText = "ON";

     }


  /*
   for (var i:int=0;i<textFields.length;i++)
   {
                      // do something

   }
  */


}

Answer 1

您最好跟踪对文本框的引用，以便随后填充它们：

var textFields:Array = new Array();
textFields[0] = compTxt;
textFields[1] = bathLightTxt;
textFields[2] = computerLightTxt;
textFields[3] = kitchenLight;
textFields[4] = livingLightTxt;
textFields[5] = descLightTxt;
textFields[6] = laundryLightTxt;
textFields[3] = ovenTxt;
textFields[8] = tvTxt; 
textFields[9] = washerTxt; 

我尝试了这种方式：

import fl.controls.*;
var textFields:Array = new Array(9);
textFields[0] = new TextInput();
textFields[1] = new TextInput();
textFields[2] = new TextInput();
textFields[3] = new TextInput();
textFields[4] = new TextInput();
textFields[5] = new TextInput();
textFields[6] = new TextInput();
textFields[7] = new TextInput();
textFields[8] = new TextInput();
textFields[9] = new TextInput();

var i:uint = 0;
for(i = 0; i < textFields.length; ++i){
   textFields[i].text = "Set text at " + i;
   trace(textFields[i].text);
}
