使用jQuery检查是否出现特殊字符 [英] checking for any occurrence of special characters with jQuery
问题描述
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.
