Implementing pseudo-paging using jquery

In the previous project encountered one such problem, the page is divided into two parts (called the unselected Device Information section and the selected device information section), the above is from the database to take out all the device information, the following is the explicit selected device information, the page is as Follows:

You can select any number of devices and click "add to select device" as Shown:

We can see, in the unselected Device Information section has a paging, this is to interact with the background data, which is called "true paging", and the selected device Information section also has a paging, this does not interact with the background data, just to solve the excessive number of data bars caused by the page too long, in response to this problem, I use jquery to access some of the information on the Internet and complete the Pseudo-pagination code shown below:
