Question

我正在尝试为Hangman游戏白衣对象编写代码，但我遇到了一个大问题;我写了一个类，我想在其他类的方法中使用它。

代码是：

var Game = {
    // All game

    rightGuess : "",
    wrongGuess : "",
    gameWord : DisplaySecretWord.selectWord(),
    gameSecret : DisplaySecretWord.getSecretWord(),

    isLetterInWord : function(letter){
        var isRightGuess = false;

        for(i = 0; i < this.gameWord.length; i++)
        {
            if(letter == this.gameWord.substring(i, i + 1))
            {
                this.rightGuess += letter;
                this.gameSecret = this.gameSecret.substring(0, i) + letter + this.gameSecret.substring(i + 1, this.gameSecret.length + 1);
                DisplaySecretWord.dispayWord(this.gameSecret);
                var el = document.getElementById("right");
                if (el != null || el != undefined ){
                el.innerHTML = this.rightGuess;
            }
            isRightGuess = true;
            this.win();
            }


        }
        if(!isRightGuess)
        {
            this.wrongGuess += letter;
            var e = document.getElementById("wrong");
            if (e != null || e != undefined ){
            e.innerHTML = this.wrongGuess;
        }
            DisplayBoard.displayPic(this.wrongGuess);
            this.lose();
        }
    },
    win : function(){
        if(this.gameSecret == this.gameWord){
        alert("Good job!!! You win! The word was " + this.gameWord);
    }
    },
    lose : function(){
        if( this.wrongGuess.length == maxWrong){
        alert("Sorry but you lose!!! The word was " + this.gameWord + " .Click 'New Game' to play again!");
    }
    },

};

当我运行我的程序时，我有：

TypeError：this.gameWord未定义

第87行：for（i = 0; i＆lt; this.gameWord.length; i ++）“。我有”这个“   在gameWord之前。

为什么会出错？

Answer 1

尝试将其设置为：

this.setAttribute("gameWord","");

然后根据需要修改

TypeError：this.gameWord未定义
