Question

在下面的代码中。如果按下按钮'A'，则文本框应填充A，如果按下按钮'B'，则应填充B等等。可以做到这一点。如果有人能指出我的flex示例会很有帮助。谢谢..

                  s='A';
                for(i=0;i<button.length;i++)
                {
                        txtLogin.text+=s;
                        s++;
                }

要将点击按钮的字符添加到txtLogin，请将clickhandler更改为：

public function clickhandler(event:Event):void
{
    var button:Button=event.target as Button;
    txtLogin.text += button.label;
}

如果您想要替换txtLogin的内容，请使用

txtLogin.text = button.label    // = instead of +=

使用flex填充文本框
