Preserved Topic: javascript protocol ? (Page 1 of 1)

Hi, this is my first post in this board. Just wondering if anyone can help me out a little here. Recently while doing some simple javascripts, I came across something which puzzled me.

using html,
<a href="javascript:void(0);" onclick="...">link</a>
and
<a href="javascript://"> onclick="...">link</a>

How does it work, the href="..."? I found out from somewhere that it's javascript protocol but that's about all. Tried using it with href="javascript:void();"... but IE6 detected syntax error... Can someone help to explain all these? Thanks in advance!!

instead of using an onClick="some JS here"

the browser makers made it so that links can fire JS events directly. The syntax is
<a href="javascript: myfunction()">
So that you can have a link that just does some Javascript nothing else. However say you want a link that does nothing when clicked, just when moused over?

The old way was this
<a href="#" onmouseover="myfunction()">

the void operator can also be used.
<a href="javacsript: void(0)" onmouseover="myfunction()"> This prevents some problems with clicking on "#" links.

The reason void() didn't work is because void isn't a *function*, it's an *operator*, like * or + or "new". It's typically followed by parenthesis to group what it works on. void(0) is the same as void 0. So, to say void() is like saying "3 + "... you're missing the operand.

hey, thks people. These explanations reallly helped.

Just wondering would adding a semi-colon ";" behind the void(0) be required? or just href="javascript:void(0)" would do? Both IE and NS are able to handle this? How about Opera?
