a tag href attribute and onclick event usage example_HTML/Xhtml_web page production

The

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

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

Another method is not to use javascript:void(0); but to use # instead. This can also be avoided. The # in the href attribute originally means the anchor point #name, so when no anchor point is specified, the page will be reached. top. # has a specific meaning, and the default is #top. If there is content after #, it will be considered a tag and the corresponding tag will be jumped to there if found on the page. If it cannot be found, it will jump to the top of the page. If you do not want to jump, , you can use ###, ### is a meaningless label specification.
