hrefhtmlquot

Note that it is the difference between jumping to the top of the page. It is better to use void(0) for better user experience.

#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. The browsing link is obviously # but it 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. Test it:
Code

<!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">
