ngPattern is one of the useful thing for validation in AnjularJs. AnjularJs ngPattern adds pattern to ngmodel. It is mainly used in text based form controls.
The following are some of the sample patterns:
<input type="text" ng-model="mail" name="mail" ng-pattern="/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i" >
Phone
<input type="text" ng-model="mobile" name="mobile" ng-pattern="/^(\+\91{1,2}[- ])\d{10}$/" />
