javascript paging class that supports page number format_javascript skills Jpage Demo - by funnyzak

Due to project needs, the front-end time needs to display all the attached images under a product in paging. Ajax requests are not considered one by one, so we simply put out all the images at once, and then perform paging when loading. There are many online jquery, property, etc. have all implemented

, but their plug-ins have many ancillary functions that are not needed, and there is no need to reference this library just for such a functional area. Consider it for speed. Of course, it doesn’t matter if your server is good, but In fact, this effect is not necessary, but I think it will be commonly used, so it is packaged into categories for future use and for those who need it to learn and use.

The following is just a simple demo. You can edit the page number style by yourself. There is a default format. No more nonsense, just read it for yourself, there are annotated instructions for use. . . To use the class (3kb), you can refer to the demo. If you don’t understand how to use it, you can leave a message.

In the future, I will slowly write down some common problems encountered in project development, as well as solutions, and share them with everyone.
