由于Repeater组件不会在mxml中生成radiobuttongroup,并且因为我无法通过ActionScript执行相同操作,因为当我尝试以这种方式创建时,radiobuttongroup没有id属性,是否有办法禁用radiobuttons什么?据我所知,我唯一可以设置和访问的是radiobuttons的groupName属性。
对于Repeater组件,我尝试直接使用xml
<mx:XML id="xquiz" source="quiz.xml" />
使用此代码:
<mx:Repeater dataProvider="{xquiz.question}" id="rep">
<mx:Label text="{rep.currentItem.content}" />
<mx:Repeater dataProvider="{rep.currentItem.answer}" id="rep2">
<mx:RadioButton label="{rep2.currentItem}" groupName="{'rbg'+rep.currentIndex}" click="checkAnswers(event)" value="{rep2.currentItem.@correct}" />
</mx:Repeater>
</mx:Repeater>
并且不能使用中继器来生成radiobuttongroup,因为它不是可见组件。
我也尝试过ActionScript方法,但使用HTTPService mxml组件来获取xml文件。
<mx:HTTPService id="srv" url="quiz.xml" resultFormat="e4x" result="handleResult(event);" fault="handleFault(event);"/>
和这里的actionscript片段:
private var xQuizData:XML
private function handleResult(event:ResultEvent):void {
xQuizData = event.result as XML;
initApp();
}
private function initApp():void {
var cnt:Number = 0;
for each (var question:XML in xQuizData.*) {
var lbl:Label = new Label();
lbl.text = question.content;
panel.addChild(lbl);
lbl.visible = true;
var cnt2:Number = 0;
for each (var answer:XML in question.answer) {
var rb:RadioButton = new RadioButton();
rb.id=String(cnt);
rb.label=answer;
rb.groupName="rbg"+String(cnt);
if (answer.hasOwnProperty("correct")) {
rb.value=true;
}
panel.addChild(rb);
rb.visible = true;
cnt2++;
}
cnt++;
}
}
我希望能够捕获来自radiobuttongroup控件的点击,但是如果使用转发器则无法生成它们,或者如果使用actionscript则无法为它们分配id。
XML内容看起来像这样:
<quiz>
<question>
<content>Some question?</content>
<answer>Answer one</answer>
<answer correct="true">Answer two</answer>
<answer>Answer three</answer>
<answer>Answer four</answer>
</question>
</quiz>

我很难从你的片段中跟踪你想要做的事情,所以这里有一个我应该完全符合你想要的片段。希望您可以查看它并根据您的问题进行调整。
public function buildVBox():void{
tempVBox.removeAllChildren();
var iterator:Number = 0;
for each (var i:XML in myXML.children()){
var tempCanv:Canvas = new Canvas();
tempCanv.id = iterator.toString();
var tempRadYes:RadioButton = new RadioButton;
tempRadYes.x = 30;
tempRadYes.y = 20;
tempRadYes.origY = 20;
tempRadYes.groupName = "rbg" + iterator.toString();
tempRadYes.value = 1;
tempRadYes.label = "Yes"
tempCanv.addChild(tempRadYes);
var tempRadNo:extRadioButton = new extRadioButton;
tempRadNo.x = 80;
tempRadNo.y = 20;
tempRadNo.origY = 20;
tempRadNo.groupName = "rbg" + iterator.toString();
tempRadNo.value = 2;
tempRadNo.label = "No"
tempCanv.addChild(tempRadNo);
var tempRadNA:extRadioButton = new extRadioButton;
tempRadNA.x = 120;
tempRadNA.y = 20;
tempRadNA.origY = 20;
tempRadNA.groupName = "rbg" + iterator.toString();
tempRadNA.value = 0; tempRadNA.label = "N/A"
tempCanv.addChild(tempRadNA);
tempVBox.addChild(tempCanv);
iterator++;
}
}
