自定义事件错误 "Incorrect number of arguments. Expected no more than 1."

Custom Event Error "Incorrect number of arguments. Expected no more than 1."

我目前正在制作一个基本的自定义事件 class,它只传递一条数据。

package {
import flash.events.Event;

public class DateEvent extends Event {

    public static const DATE_SET: String = "exampleEvent";

    public var calendarObj: Object;

    public function DateEvent(type: String, calendarObj: Object = null) {

        this.calendarObj = calendarObj;

        super(type, false, false);

    }

    override public function clone(): Event {

        return new DateEvent(type, calendarObj);
    }
}}

像这样调用事件时:

selectedDate = new Date(displayedYear, displayedMonthNum, displayedDate, displayedHour, displayedMins);
        trace(selectedDate);

        dispatchEvent(DateEvent(DateEvent.DATE_SET, selectedDate));

我遇到 "Incorrect number of arguments" 错误。我很困惑,因为我没有超过我应该通过的(我认为)。

您在调用 DateEvent 构造函数之前缺少 new 关键字。像这样-

dispatchEvent(new DateEvent(DateEvent.DATE_SET, selectedDate));
