Example of using the href attribute and onclick event of a tag

The a tag is mainly used to implement page jump, which can be achieved through the href attribute or in the onclick event.

IE6 first runs the events bound to the DOM itself, such as onclick; if bubbling is not prevented, the href attributes will be executed sequentially. And void(0); does not need to execute any event, so IE6 tells the browser not to execute any event (overwriting the previous action), and terminating the bubbling is equivalent to return false; so the browser does not execute any action. So just prevent the bubbling event within the onclick event.

Another way is to use # instead of javascript:void(0);. The # in the href attribute originally means the anchor#name, so when no anchor is specified, it will go to the top of the page. # has a specific meaning. The default is #top. If there is content after #, it will be considered a tag and the corresponding tag will be found on the page to jump to that place. If it is not found, it will jump to the top of the page. If you don't want to jump, you can use ###. ### is a meaningless tag specification.
