The work of the more practical JS verification and data processing of dry goods

In the development of Web projects, inevitably encountered a variety of Web page data processing, such as the user entered in the form of the phone number, mailbox, amount, ID number, password length and complexity of the verification, and back to the background

The formatting of the data, such as the amount, returns a value of NULL, and a calculation for a day or a January before or after the specified date.

When it comes to validating data and forms, I'm sure that everyone, like me, likes to find relevant methods on the Internet because it's time-consuming to write. Today, I would like to share with you some of the common things that I have summed up in my work

Of JS.
