12-May-2023Yes, it is possible to create custom validation rules using jQuery validation. To do this, you need to use the addMethod method of the jQuery validation plugin. The addMethod method takes two arguments: the name of the custom validation rule and the function that performs the validation. The function must return a Boolean value. If the function returns true, then the form field is considered valid. If the function returns false, then the form field is considered invalid.
The following is an example of how to create a custom validation rule that checks if a value is a valid email address:

To use the custom validation rule, you would simply add it to the

object of the jQuery validation plugin. For example, the following code would use the custom validation rule to validate theemail
