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.

Answer 1

if (value.search(/[\s+]/) == -1) {
    return true;
}
