Finally, the JQUBAR1.0 plug-in system cannot be tested due to a rush of time. If you are interested, you can download the JQUBAR1.0 plug-in here.

We sincerely thank you for your valuable comments on the plug-in. Based on your comments, I will take the time to upgrade the JQUBAR1.0 plug-in.

At the same time, I hope this article can help you solve problems encountered during development.
