#Contains a location information
The default anchor is #top, which is the top of the web page
And javascript:void(0) only represents a dead link
This is why sometimes the page is very long and the browsing link is obviously #but jumps to the top of the page
But javascript:void(0) is not the case
So it is best to use void(0) when calling the script
You can use the following example to test it:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <meta http-equiv="Content-Type" content="text/html;charset=UTF-8" /> </head> <body> 这里是页首..... <p>1 </p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <p> 1</p> <a href="#">这是会跳到页首的</a> <a href="javascript:void(0)">这个不会跳动</a> </body> </html>
