After I made the amber infinitus classification linkage menu Javascript edition, I made a presentation on the blue ideal and CSDN. Meihua xuexiong raised the issue of inefficiency on CSDN, I also realized this. I planned to complete the project after it was completed. However, I found some information on the Internet and finally made an infinitely classified Association menu for this AJAX version. Due to the rush of time, it was rough, but AJAX technology had been used to achieve unlimited linkage. Later, the version was improved.
I hope to provide you with some help. If you have good suggestions or bugs, you can reply to or browse http://www.51ajax.com/bbs/.
