我怎么能只允许字母和特殊字符用常规的前pression？

How can I allow only letters and special characters with a regular expression?

推荐答案

我建议你使用 GSkinner 的正则表达式构建器和试验了很多在右手侧上的例子。有许多变化得到这个工作做好。如果你想成为明确的，你可以使用：

I suggest you use GSkinner's REGEX builder and experiment with a lot of the examples on the right hand side. There are are many variations to get this job done. If you want to be explicit you can use:

/[a-zA-Z!@#$%¨&*()-=+/*.{}]/

托尼的回答也将正常工作，但要承担更多额外的字符比您在您的评论已经定义的值。

Tony's answer will also work, but includes more extra characters than the ones you've defined in your comment.
