Javascript 卡片对象的计分手
奇怪的是,现在在用Javascript 卡片对象的计分手,javascript,Javascript,奇怪的是,现在在用替换循环的中的s之后s,它现在响应ReferenceError:expected')。它想要什么?(错误似乎出现在最后一行控制台中。日志行,因为注释它会使错误消失。)我数了数,在那一行我有2个(和2个) 您的问题似乎在这里: // This code defines the Object constructor Card, used to make the card objects var Card = function(card) { this.face = theF

for(i=0,i你最好把所有的JavaScript代码都放进去。这将帮助你清除任何可能导致问题的语法问题,并有助于实现跨浏览器兼容性。aww,来吧!我想我已经检查过了!谢谢!不客气。查看JSLint(Mike_K发布)同样,这也很有帮助。
