Html tag href confusion record_html/css_WEB-ITnose

Recently, I encountered a small problem at work (doing some web activities for a mobile game platform, which involved a button link, so I used to use the a tag, and after the Click response, I walked a js Code logic - a sharing WeChat pop-up box pops up. There is no problem on Chrome and Android platforms. During the testing phase, it was found that there was a problem on the Ios platform. After the pop-up box flashed for a while, the page was re-rendered and the pop-up box was naturally hidden. ), after some investigation, although the problem is solved, it does not mean that the reason has been figured out.
