Javascript URL validation

Question

I wrote a javascript validation script to validate if the URL contains '+' or whitespaces.

$.validator.addMethod("reportFileURL",
                    function(value,element){
                        if(((value.search(/[+]+/)) == -1) 
                                  && ((value.search(/[ ]+/))) == -1){
                           return true;
                        }
                     },"Invalid filename");

Can i write the script more precise than this.

Thanx Michael it works...:) By the way can you suggest me a book or website to use regex for javascript form validation.

@SangramAnand glad it was helpful :) I use regex.larsolavtorvik.com to test my regular expressions of JS & PHP

If you want to target all whitespace (and not just the space character), you should change the regex to /[\s+]/.

return value.search(/[ +]/) == -1;
