This is a creation in Article, where the information may have evolved or changed. What are business rules?

encapsulate the same working code into different classes separately, and then process them through a unified policy processing class. OK, let's first define the Policy Processing class. The Code is as follows: Var validator = {// all the places where the verification rule processing class can be stored, and types :{} will be defined separately later. // the error message messages corresponding to the verif

This article mainly introduces the parsing of rule instances for Javascript type conversion, involving knowledge about javascript type conversion. If you are interested in this article, let's learn about it. type conversion can be divided into implicit conversion and explicit conversion, implicit conversions are the automatic conversions performed by the program at runtime. Explicit conversions are manually forced conversions of types. Javascript vari

As an easyui validation plug-in, it is a defect that does not implement multiple verification capabilities. For example, to limit the format to email and the maximum length to 20, we need to extend a rule, and the length requirement is easily changed. If it becomes 30, we have to expand another rule, so it is necessary for multi-factor verification. The implementation method is simple, and a new
