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.

Above ValidateDate() function will check the argument value against this regular expression. If the entered value is in mm/dd/yyyy or mm-dd-yyyy format then this function will return true, otherwise false.
validator. addMethod('min-length', function (val, element) { // do stuff // the error message here needs to be dynamic }, 'The field cannot be less than than ' + element. attr('data-min') + // it is within the closure, but it can't grab it ' length. ');
The jquery validate plugin requires a form element to function, so you should have your form fields (no matter how few) contained inside a form. You can tell the validation plugin not to operate on form submission, then manually validate the form when the correct submit button is clicked.
fn , so simply check whether it exists or not; if (typeof jQuery. fn. validationPlugin === "function") { // It's loaded } else { // It's not. }

/^[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]+
