jQuery Validator : Validate AlphaNumeric + Space and Dash

I have jQuery validation plugins (http://docs.jquery.com/Plugins/Validation) installed on my website.

I'm using this code to validate alpha-numeric from text field, and it works. but it doesn't allow space and dash (-).

$.validator.addMethod("titleAlphaNum", function(value, element, param) 
{
return value.match(new RegExp("^" + param + "$"));
});

how to make it works with space and dash? thanks.

working demo http://jsfiddle.net/cAADx/

/^[a-z0-9\-\s]+$/i should do the trick!

g = /g modifier makes sure that all occurrences of "replacement"

i = /i makes the regex match case insensitive.

good read: http://www.regular-expressions.info/javascript.html

Hope this helps,

code

$(function() {

    $.validator.addMethod("loginRegex", function(value, element) {
        return this.optional(element) || /^[a-z0-9\-\s]+$/i.test(value);
    }, "Username must contain only letters, numbers, or dashes.");

    $("#myForm").validate({
        rules: {
            "login": {
                required: true,
                loginRegex: true,
            }
        },
        messages: {
            "login": {
                required: "You must enter a login name",
                loginRegex: "Login format not valid"
            }
        }
    });

});​

I think it will work if you pass the following RegExp as param:

[A-za-z0-9_\-\s]+
