IMPORTANT NOTE ABOUT EMAIL VALIDATION. As of version 1.12.0 this plugin is using the same regular expression that the HTML5 specification suggests for browsers to use. We will follow their lead and use the same check. If you think the specification is wrong, please report the issue to them. If you have different requirements, consider using a custom method. In case you need to adjust the built-in validation regular expression patterns, please follow the documentation.
For an invalid field, the default output for the jQuery Validation Plugin is an error message in a element. This results in two elements pointing to a single input field using the for attribute. While this is valid HTML, it has inconsistent support across screen readers.
For greater screen reader support in your form's validation, use the errorElement parameter in the validate() method. This option outputs the error in an element of your choice and automatically adds ARIA attributes to the HTML that help with screen reader support.
aria-describedby is added to the input field and it is programmatically tied to the error element chosen in the errorElement parameter.
