我到处都找过,虽然有很多解释,但我似乎无法理解。
这是我的xml结构:
<question>
<q1> Who coined the term “Clinical Psychology”? </q1>
<answer> Lightner Witmer </answer>
<option1> Stanley Hall </option1>
<option2> Lightner Witmer </option2>
<option3> Henry P. David </option3>
</question>
我可以循环浏览fine,找出问题和答案,然后将它们放入单独的数组中。我遇到的问题是循环并将选项拉入多维数组,比如
var one:Array = new Array( 3 );
one[0] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[1] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[2] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
如有任何帮助,我们将不胜感激。
var answers:Array = [];
for(var i = 0; i< xml.question.length; i++){
var node:Array = [];
node.push(xml.question[i].option1);
node.push(xml.question[i].option2);
node.push(xml.question[i].option3);
//or
var node:Array = [xml.question[i].option1,xml.question[i].option2,xml.question[i].option3];
answers.push(node);
}
现在可以检索问题的答案:
answers[questionIndex][answerIndex];
希望对有所帮助
我不确定你是否以你想要的形式设置了数组,但是,偏离了你发布的代码
你试过了吗?
var one:Array = new Array( 3 );
one[0] = new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );
one[1] = new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );
one[2] = new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );
有了这样的东西,我更喜欢有一个以对象为元素的问题数组。每个对象都将包含有关该问题的所有信息。这将允许为每个问题分配一个自定义类。或者可以使用基本的动态对象
var questions:Array = new Array();
var obj:Object = new Object();
obj.question = "Who coined the term 'Clinical Psychology'?"
obj.correctAnswer = "Lightner Witmer";
obj.possibleAnswers =new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );
questions.push( obj );
