JSLint - Unexpected '\' before '.'

I am getting the following warning in JSLint for my regex expression.

enter image description here

Unexpected '\' before '.'.
var regexForEmail = /^(([^<>()\[\]\.,;:\s@\"]+(\.[^<>()\[\]\.,;:\s@\"]+)*)|(\".+\"))@(([^<>()[\]\.,;:\s@\"]+\.)+[^<>()[\]\.,;:\s@\"]{2,})$/i;

Can someone help me how to fix it or is there any other way to suppress the warning?

Thanks in advance

Dinesh.

. doesn't have special meaning when it's inside square brackets, so there's no need to escape it there. " has no special meaning at all in regular expressions, so you never need to escape it.

var regexForEmail = /^(([^<>()\[\].,;:\s@"]+(\.[^<>()\[\].,;:\s@"]+)*)|(".+"))@(([^<>()\[\].,;:\s@"]+\.)+[^<>()\[\].,;:\s@"]{2,})$/i;

The only characters that are special inside square brackets are backslash, hyphen, right square bracket, and caret at the beginning.
