如果我有一组特殊字符，例如:!@#$%^&*(){}[]<>?/|-如何检查字符串(或字段值)中是否存在任何这些特殊字符?尝试添加一种方法jQuery验证程序插件，如果其中存在任何一个，该插件将拒绝该字段.我意识到这要求很多，正则表达式正在杀死我.

If I have a set of special characters like: !@#$%^&*(){}[]<>?/|- how could I check for existence of any of these in a string ( or field value)? Trying to add a method jQuery validator plugin that would reject the field if any of them are present. I realize this is asking for a lot, regex is just killing me.

推荐答案

尝试一下:

/[!@#$%\^&*(){}[\]<>?/|\-]/

您只需要转义].在字符类([])中，其他字符将按字面意义进行解释.

You only need to escape the ]. Inside a character class ([]), the other characters are interpreted literally.
