This time, the organizational structure of the original code is used to re-enhance the function. Currently, there are two other small issues. The first one is that the custom pop-up layer in ie6 will not be able to cover the select, currently, it has not been added to the component. You can add an ifame to the custom div to mask it. the pop-up layer of the component can be hidden. The second problem is that the browser cannot automatically follow the browser window because it is absolutely positioned. You will know when you try it. Of course there are certainly many problems, but I think these two are important. I will list them for now and fix them later.
The following code contains comments and can be run directly.
