How to use PHP to implement the code for three-level linkage effects based on layUI during development

This article mainly introduces the code on how to use PHP to realize the three-level linkage effect based on layUI in development. It has a certain reference value. Now I share it with everyone. Friends in need can refer to it

Backend development often uses the layUI framework to make the entire page look beautiful and elegant. However, sometimes some native effects cannot be used on the layUI framework. For example, we recently encountered the select effect of three-level linkage between provinces, cities and counties. Different from the previous ones, in the layUI framework, you need to pay attention to the lay-filter attribute of select to listen for events, and form.render() is needed to re-render. To solve these two problems, linkage is no longer a problem. Let me share it with you below.
