我有这段代码，没有显示任何错误，但无法工作；你能帮助我吗？我只想在我的表单上放置新按钮：

minHeight="600">
    <fx:Script>
        <![CDATA[
            import mx.controls.Alert;
            import mx.controls.Button;
            function onClick() {
                var button2:mx.controls.Button = new mx.controls.Button();
                button2.x = 100;
                button2.y = 100;
                Form1.addChild(button2);
            }
        ]]>
    </fx:Script>
    <s:Form id="Form1" x="0" y="0" width="100%" height="100%">
        <s:Button id="button1" label="button1" click="onClick()" />
    </s:Form>
</s:Application>

当我尝试运行它时出现运行时异常。

这应该可以解决问题：

protected function onClick():void {
var button2:mx.controls.Button = new mx.controls.Button();
//button2.x = 100; These two lines are obsolete because form handles the layout of its children automatically
//button2.y = 100;
Form1.addElement(button2);
}

使用 Spark 容器，您需要执行 addElement() 而不是 addChild()；

您可以在 adobe livedocs 中找到有关使用 Spark 组件的更多信息，网址为 http: //help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf61c8a-7ff9.html

干杯

There was a runtime exception when I tried to run this.

This should do the trick:

protected function onClick():void {
var button2:mx.controls.Button = new mx.controls.Button();
//button2.x = 100; These two lines are obsolete because form handles the layout of its children automatically
//button2.y = 100;
Form1.addElement(button2);
}

With Spark containers you need to do addElement() instead of addChild();

You can find more information about working with spark components in the adobe livedocs at http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf61c8a-7ff9.html
