I'd like to validate a form using vue-js 2.3 and element-ui
Apparently, they use async-validator to validate the form. The documentation is here.
Example

Problem
Uncaught Error: Unknown rule type D*([2-9]d{2})(D*)([2-9]d{2})(D*)(d{4})D*
I do not know how to validate a field with regexp. I find the documentation not explicit enough on that topic.
