using the jquery validation plugin, how can I add a regex validation on a textbox?

Question

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?

Answer 1

Not familiar with jQuery validation plugin, but something like this should do the trick:

var alNumRegex = /^([a-zA-Z0-9]+)$/; //only letters and numbers
if(alNumRegex.test($('#myTextbox').val())) {
    alert("value of myTextbox is an alphanumeric string");
}
