Setting events for html hyperlinks does not use href for Skip.

Sometimes, we need to use the <a> hyperlink instead of href to complete the jump, for example, <a href = "#" onClick = "fun () "> </a>. In this way, the page will not jump. But it also brings some negative problems, such as the title of the page becoming "#", or the scroll bar or something on the page. This is because after the onClick event is executed, <a> jump to the address pointed to by href, and "#" is an anchor. By default, it is the top of the web page, so it will bring the problems mentioned above.

There are two solutions:

1. Add the return false statement to the onClick event, for example:
Copy codeThe Code is as follows:
<A href = "#" onClick = "fun (); return false;"> click </a>

2. Use void (0) instead of #, for example:
Copy codeThe Code is as follows:
<A href = "javascript: void (0)" onclick = "fun ()"> click </a>
