Editor to share with you how the a tag in html uses the href attribute and the onclick event, I believe most people don't know much about it, so share this article for your reference. I hope you will get a lot after reading this article. Let's learn about it together.

The a tag is mainly used to jump pages, either through the href attribute or in the onclick event.

This code is fine in mainstream browsers, but it can't jump in IE6. What is the reason for this?

_ javascript:void (0)

Void (arg); can be understood as a function that always returns null, but its arguments cannot be empty. Its parameters can be arbitrary expressions or even functions.

IE6 first runs events bound by DOM itself, such as onclick;, which executes the href property sequentially if it does not prevent bubbling. While void (0); does not need to execute any event, IE6 tells the browser not to perform any event (overwriting the previous action), and ending bubbling is equivalent to returnfalse;, so the browser does not perform any action. So all you have to do is to stop bubbling within the onclick event.

In this way, it can work properly under IE6.

Another way is not to use _ javascript:void (0); you can avoid using # instead. The # in the href attribute originally means anchor # name, so it goes to the top of the page when no anchor is specified. # has a specific meaning. The default is # top. If the content after # is considered to be a tag and jumps there from the page to find the corresponding tag, it will jump to the top of the page. If you do not want to jump, you can use #, # is a meaningless tag assignment.
