Question

您好我正在为学校开设一个课程，我希望有一个页面，我有一个反映数字步进器的滑块，反之亦然，但每当我在网上找到一个教程时，它一直给我错误，最新的这是1120：访问未定义的属性NumericStepperEvent。我对继续使用其他步进器犹豫不决，因为我不确定如何让它工作，但我需要在星期五之前完成这一部分。任何帮助将不胜感激。

谢谢马特

您需要告诉编译器要使用哪些类。目前它还不知道NumericStepperEvent是什么。

在顶部添加其他导入添加：import mx.events.NumericStepperEvent;

此外，我建议将写入Event:SliderEvent的参数变量更改为小写event:SliderEvent，因为这可能会导致其他编译器错误。
