Introduction to the difference between the href and onclick events of a tag_Basic knowledge

1. The onclick event is executed first. If the onclick event returns a false value, the href will no longer be executed.
2. href="#" defaults to the anchor point #top, so the page will jump to the top when there is a scroll bar. The best solution is href="javascript:void(0);".
3. The returned content in href will flush out the information of the current page.
