jQuery Method for Validation Plugin - "field must include at least one number"
Here's a method you can use with the validation jQuery plugin to make sure a field (like a password field) includes at least one number.
$.validator.addMethod("atleastonedigit", function(pass) {
if (pass == "") {
return true;
}
return ((/[0-9]+/).test(pass));
}, "This field must contain at least one number");
