闪存单选按钮：我如何才能所选的单选按钮？ [英] Flash radiobutton: how do I get the selected radiobutton?

问题描述

我有几个单选按钮我拖放同一组中。在main.as我添加点击事件监听器。

I have a few radiobuttons I drag and drop within same group. In main.as I added click event listener.

如何获得所选择的单选按钮？处理目标参数不包含任何引用。

How do I get the selected radiobutton ? handler target argument doesn't contain any reference to it.

推荐答案

抢参考目前的RadioButtonGroup，并访问选择的参考，这将返回一个引用到组中选定当前单选按钮。

Grab a reference to the current RadioButtonGroup and access the selection reference, this will return a reference to the current radio button that is selected in the group.

var rbg:RadioButtonGroup = RadioButton(e.currentTarget).group;

var selectedRadioButton:RadioButton = rbg.selection;

//Get the group name
trace(selectedRadioButton.groupName);

或者你可以有你的单选按钮的复合if语句，像这样：

Alternatively you can just have your radio buttons in a compounded if statement like so:

if(radioButton1.selected == true){

}else if (radioButton2.selected == true){

}
