checking for any occurrence of special characters with jQuery

问题

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.

Try this:

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

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