Today, I will talk to you about the regular expression to judge the modified version of the operator js code of the number entered. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

Function: determine the operator who filled in the number

The function is implemented according to the following standards

Mobile: 134-139 151 188

China Unicom: 130-132 156

Telecom: 133 189 155

Queries about numbers outside these ranges will indicate that no data information is available for the time being.

At the same time, due to the implementation of carrying numbers into the network, the number operators change and there is uncertainty.

This program is only used for regular expression learning and communication, and can be spread at will, but the author is not responsible for the errors caused by the program!

The code is as follows:
