I need regex to search string for alphanumeric, (, ), -, ., / and ampersand(&).

Right now i m using this regex in client side validation

 [^A-Za-z0-9.)(/-\&]

EDIT:

I want to s开发者_StackOverflowearch my string for special characters VAL.search(/[^A-Za-z0-9.)(/-\&]+/g)==-1

Escape the backslash, put the dash at the end of the character class.

[^A-Za-z0-9.)(/\\&-]

Not sure why you included ^, as this negates the character class.

Try this:

VAL.search(/[^a-zA-Z0-9.()/&-]/g) == -1
