Question

我总是收到此错误＆＃34; Uncaught SyntaxError：意外的令牌＆＃34;。但我无法在我的代码中找到所述错误。我已经检查了括号，没有任何问题。请帮我弄清楚错误是什么。谢谢！

Answer 1

第25行，for (var i=1; i < data.getNumberOfColumns(); i++) {应为for (var i=1; i < data.getNumberOfColumns(); i++) {（请注意＆lt;）

Answer 2

我使用JSHint对您的代码进行了操作，并且您没有先关闭for语句。如果你真的需要在script标签内编写代码，我真的建议在外部文件中使用Lint工具编写它，然后复制并粘贴它，这样可以防止这样的错误。
