Question

完整错误： TypeError：错误＃1034：类型强制失败：无法将flash.events::KeyboardEvent@4ff2301转换为flash.events.MouseEvent。

我使用ActionScript 3进行了一个非常简单的简单测验教程。但是一旦完成，我收到上述错误。这个教程已经很老了，所以只是希望这里有人可以检查它，看看我是否犯了一个明显的错误。

    Enter_btn.addEventListener(MouseEvent.CLICK, go);

var quizModel:Array = [{q:"2+2", a:"4"}, {q:"What colour is a banana = ?", a:"Yellow"}];
var user_ans:Array = new Array();
var newQuizModel:Array = shuffleArray(quizModel);
stage.addEventListener(KeyboardEvent.KEY_DOWN, go);


function showQuiz(index:int):void
{
    question_txt.text = newQuizModel[index]["q"];
}


var index:int = 0;
question_txt.text = newQuizModel[index]["q"];
var userAnswer:String = "";
function go(e:MouseEvent)
{


    userAnswer = answers_txt.text;

    if (userAnswer == newQuizModel[index]["a"])
    {
        rightwrong_txt.text = "Your answer is correct!";
    }
    else
    {
        rightwrong_txt.text = "Your answer is wrong";
        return;
    }

    index++;
    index%= quizModel.length;
    showQuiz(index);
}

function shuffleArray(arr:Array):Array
{
    var l:Number = arr.length - 1;

    for (var it:uint = 0; it<l; it++)
    {
        var r:int = Math.round(Math.random() * l);  /// l is an L
        var tmp:Object = arr[it];
        arr[it] = arr[r];
        arr[r] = tmp;
    }
    return arr;
}


showQuiz(index);

Answer 1

将go(e:MouseEvent)替换为go(e:Event)。

您向MouseEvent和KeyboardEvent注册了一个事件处理程序。当MouseEvent.CLICK被触发时，将调用函数go。 MouseEvent的实例将在函数go内传递。没有错误。但是当KeyboardEvent.KEY_DOWN被触发时，KeyboardEvent的实例将在go函数内传递。并且发生错误。对不起我的英语不好。你明白了吗？
