我不断收到此错误消息：

未捕获的 SyntaxError：意外的标识符

向时钟添加毫秒时。我是从书本上抄下来的，所以不知道哪里出了问题。

看起来你在+这里错过了一个：

 document.write(hours + ":" + minutes + ":" + seconds + ":" mil);

线

document.write(hours + ":" + minutes + ":" + seconds + ":" mil);

应该读

document.write(hours + ":" + minutes + ":" + seconds + ":" + mil);

之前有一个+缺失mil
