This article mainly introduces js to realize the display of friend links shared by WeChat. It is helpful for learning ASP.NETprogramming technology. Interested readers Friends, you can refer to
Usually when I make a page and want to share it with friends through WeChat, the title and description displayed are not what I want. I checked some information and found out that it is done through js. The control
display effect is as follows:
##title, description, and shared Pictures are all controlled by js. js code is as follows
