Zhang Xin Xu This article is also very interesting, as a slight code neat programmer, the tangled when tangled: is the habit or norms!? Question: Why use href= "javascript:void (0);"?

A tag to write href attribute! ~ with href attribute, natural mouse hand type, as well as can be keyboard focus and focus time to enter analog click behavior (Support carriage return click and default can get focus).

The difference between href= "#" and href= "javascript:void (0)"

# contains a location information, the default anchor is #top that is the top of the page.

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

When the page is long, it uses # to locate the page in the format:# + ID.

If you want to define a dead link please use Javascript:void (0).

<a href= "javascript:void (0);" > I'm not responding to!</a>
<a href= "#pos" > point I position to the specified position!</a>
<br>
...
<br>
<p id= "POS" > trailing anchor points </p>
