Talking about the difference between href= #与href =javascript:void (0)

# "contains a location information

The default anchor point is #top, which is the upper end of the page

and javascript:void (0) only represents a dead link

That's why there are times when the page is very long browse the link is obviously # but it beats to the top of the page

and javascript:void (0) is not so

So it's best to use void when calling scripts (0)

or <input onclick>.

<div onclick>, etc.

Several ways to open a new window link

1.window.open (' url ')

2. Using Custom Functions

<script>
function Openwin (tag,obj)
{
Obj.target= "_blank";
Obj.href = "web/substation/substation.aspx?stationno=" +tag;
Obj.click ();
}
</script>

<a href= "javascript:void (0)" onclick= "Openwin (3,this)" >LINK_TEST</a>

Window.location.href= ""

If it is a #, there will be a jump to the top of the situation, the personal collection of several solutions:
1:<a href= "# # # ></a>
2:<a href= "javascript:void (0)" ></a>
3:<a href= "javascript:void (null)" ></a>
4:<a href= "#" onclick= "return false" ></a>
5:<span style= "Cursor:hand" ></span> (as if not shown in FF)

Careful use of javascript:void (0)

In JavaScript, Void is an operator that specifies that an expression is evaluated but does not return a value.
The void operator uses the following format:
1. javascript:void (expression)
2. Javascript:void expression
Expression is a standard of JavaScript to evaluate. Parentheses on the outside of the expression are optional, but writing is a good habit. We can use the void operator to specify hyperlinks. The expression is evaluated but does not load anything at the current document. The code for the polygon creates a hyperlink that doesn't happen when the user clicks it. void (0) evaluates to 0 when the user clicks on the link, but does not have any effect on JavaScript.

<a href= "javascript:void (0)" > Click here Nothing will happen </a>

That is, you can use void (0) to perform some processing but not to refresh the page as a whole, but be careful when you need to refresh the page.

In fact, we can use <a href= "Javascript:void (Document.form.submit ())", this sentence will be a submit operation. Then what situation with void (0) More, no refresh, of course, Ajax, 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 this page needs to be refreshed overall

You can use the void operator to specify a hyperlink. The expression is evaluated but does not load anything at the current document.
The following code creates a hyperlink, and nothing happens when the user clicks it. void (0) evaluates to 0 when the user clicks on the link, but does not have any effect on JavaScript.

The following code creates a hyperlink that submits a form when the user clicks it.

<a href= "Javascript:void (Document.form.submit ())" >
