How to Remote call using bootstrap validator

I only just found out that the bootstrap validation plugins has a validation rule called “remote” which can be used to make an ajax request instead of specifying a custom rule which has an ajax call it in. This will save you heaps of time with those custom validation rules. This is very interesting and simple.
