What does javascript:void(0) mean and an example introduction_javascript skills

void is an operator in Javascript, which specifies that an expression is to be evaluated but does not return a value.

void operator usage format is as follows:

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

expression is a Javascript standard to be calculated expression. The parentheses outside the expression are optional, but are a good practice to write. (Implementation version Navigator 3.0)

You can use the void operator to specify a hyperlink. The expression will be evaluated but nothing will be loaded into the current document.

The following code creates a hyperlink that will cause nothing to happen to the user later. When the user links, void(0) evaluates to 0, but nothing happens on Javascript:

Nothing happens here< ;/A>

The following code creates a hyperlink and the user will submit the form when clicking:

Submit form here

a href=# and a href=javascript:void(0) There are several ways to link:
# 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 #
Jumps to the top of the page

, but javascript:void(0) is not like this

, so it is best to use
void(0)
or
< when calling the script input onclick>

etc.

Several ways to link

1.window.open(''url'')
2. Use a custom function

Copy code The code is as follows:

<script> <br>function openWin(tag, obj) <br>{ <br>obj.target="_blank"; <br>obj.href = "Web/Substation/Substation.aspx?stationno=" tag; <br>obj.click(); <br> } <br></script>
