Javascript 请检查我的代码，它不工作。并且总是说它不是控制台中的函数

我用javascript创建了一个游戏，但是这个游戏不起作用。它总是说它不是Chrome日志中的函数

所以我想知道这有什么问题。像刘备。战斗等等。这是一个游戏，你打曹操。我创造了3个角色。如果刘备还活着，游戏就结束了。如果曹操不在，你就赢了

        var attack = Math.random()
        if(attack < 0.5){
            caocao.hp-=this.power;
            caocao.checkalive();
            checkwin()
        }
        else{

最后一个括号丢失了，正如Jaromanda在this.fight之前提到的那样

5秒答案-丢失}。如果你格式化了你的代码，你会看到-你使用firefox吗？使用带有漂亮打印按钮的scratchpad:PJSFIDLE有一个整洁的选项——看看你的代码——现在很明显，不是吗
