Summarize the differences between href=javascript:void(0) and href=#

What are the differences between href=# and href=javascript:void(0)? The following is my summary of the difference between href=javascript:void(0) and href=#.

#"Contains a location information

The default anchor point 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 like this

So When calling the script, it is best to use void(0)

<a  href="javascript:void(0)" onclick="openWin(3,this)">LINK_TEST</a>
window.location.href=""

Use with caution JavaScript:void(0)

void in JavaScript is a operator, which specifies to evaluate an expressionbut does not return a value
void. The operator usage format is as follows:

1. javascript:void (expression)
2. javascript:void expression

expression is a JavaScript standard expression to be evaluated. The parentheses outside the expression are optional, but it is a good habit to write them. The void operator specifies a hyperlink. The expression is evaluated but nothing is loaded into the current document. The code above creates a hyperlink and nothing happens when the user clicks the link. (0) is calculated as 0, but has no effect on JavaScript

<a href="javascript:void(0)">单击此处什么也不会发生</a>

That is to say, if you want to perform some processing without refreshing the page as a whole, you can use void(0). , but when you need to refresh the page, you need to be careful.

In fact, we can use 870cd383f150d4ad83c7c7790d241cd0 , this sentence will perform a submit operation. So under what circumstances are void(0) used more often? Without refresh, of course it is Ajax. If you look at the Ajax web page, you will generally see a lot of void(0). ,:), so before using void(0), it is best to think about whether the page needs to be refreshed as a whole.
