I am using the jquery validation plugin from: http://bassistance.de/jquery-plugins/jquery-plugin-validation/
How can I add a regex check on a particular textbox?
I want to check to make sure the input is alphanumeric.
Define a new validation function, and use it in the rules for the field you want to validate:
$(function ()
{
$.validator.addMethod(loginRegex, function(value, element) {
return this.optional(element) || /^[a-z0-9-]+$/i.test(value);
}, Username must contain only letters, numbers, or dashes.);
$(#signupForm).validate({
rules: {
login: {
required: true,
loginRegex: true,
}
},
messages: {
login: {
required: You must enter a login name,
loginRegex: Login format not valid
}
}
});
});
