在多個文本字段中顯示隨機排序的數組

Question

我有一個隨機排序的數組，例如3個項目。我不想在一個動態文本框中顯示所有3個項目（請參閱下面的代碼），而是希望在3個不同的文本框中顯示每個項目。我該如何去做這件事？

var Questions:Array = new Array; 

Questions[0] = "<b><p>Where Were You Born?</p><br/>"; 
Questions[1] = "<b><p>What is Your Name?</p><br/>"; 
Questions[2] = "<b><p>When is Your Birthday?</p><br/>"; 

function randomize (a:*, b:*): int { 
    return (Math.random() > .5) ? 1: -1; 
} 

questions_txtbox.htmlText = Questions.toString() && Questions.join("");

下面的代碼完成了你所要求的，儘管洗牌功能很粗糙，但它完成了工作。我還動態生成了三個文本字段，而不是在舞臺上創建它們，併爲它們提供了唯一的實例名稱，因此，您需要根據需要調整這些新文本字段的x/y座標。我在Flash CC 2014上測試了它，並且它工作正常。

import flash.text.TextField; 

var Questions:Array = new Array(); 
Questions[0] = "<b><p>Where Were You Born?</p><br/>"; 
Questions[1] = "<b><p>What is Your Name?</p><br/>"; 
Questions[2] = "<b><p>When is Your Birthday?</p><br/>"; 
var shuffleAttempts:int = 10 * Questions.length; 
var questionTextFields:Array = new Array(3); 

function randomize (a:*, b:*): int { 
    return (Math.random() > .5) ? 1: -1; 
} 

function shuffleQuestions(arr:Array):void { 
    var temp:String; 
    for(var i:int = 0; i < shuffleAttempts; i++) { 
     var randIndex1:int = Math.floor(Math.random() * Questions.length); 
     var randIndex2:int = Math.floor(Math.random() * Questions.length); 

     if(randIndex1 != randIndex2) { 
      temp = Questions[randIndex1]; 
      Questions[randIndex1] = Questions[randIndex2]; 
      Questions[randIndex2] = temp; 
     } 

    } 
} 
shuffleQuestions(Questions); // shuffle question list 

for(var questionIndex:int = 0; questionIndex < 3; questionIndex++) { 
    if(questionIndex < Questions.length) { 

     var questionField = new TextField(); // create new text field 
     questionField.htmlText = Questions[questionIndex]; // take a question from the questions list and set the text fields text property 
     questionField.y = questionIndex * 20; // move the text field so that it does not overlap another text field 
     questionField.autoSize = "left"; // autosize the text field to ensure all the text is readable 

     questionTextFields[questionIndex] = questionField; // store reference to question textfield instance in array for later use. 

     addChild(questionField); // add textfield to stage 
    } 
}
