Bootstrap Validator to validate open and close time with callback

Bootstrap Validator to validate open and close time with callback

In this jQuery Bootstrap tutorial, I will let you know how to validate open and close time with the help of callback feature.

This example will helpful when you have two timepicker to pick open and close time and you are tring to validate open time must be less than close time or close time must be greater than open time.

In this example, I have created a custom method for time validation and pass this method inside the callback of Bootstrap form validator.

This is very useful when you are developing a system where you need to have a registration form with start and end time of a merchant/vendor and there you need to set some validation rules like vendor can not select invalid time format or vendor can not left empty value for the required field.
