To achieve the selection of secondary regions, there are roughly two forms of expression in the front end. First, you put two text boxes on it. When you click on text box one, the province list appears. When you click on text box two, the province's city list appears; the second is to put two drop-down boxes, select one in the first drop-down box, and then go to the second to select the corresponding city area. Of course, there are other ways. I will do one here, that is, the drop-down selection, the code is as follows:

I originally planned to use loops to generate an array for demonstration, but think about it, since it is a cascade of a second-level region, it is better to be standardized so that everyone can see clearly and make clearer choices. Although this article is mostly a place name...
