onKeyPress for a link

[juglesh]

hello, I just want to be able to use a keypress to do the same as clicking a
link. such as [right arrow] will 'click' a certain link, while [left arrow]
will 'click' a different link.

thanks for your time,

<script type="text/javascript">
function keyHandler( e )
{

if( !e )
{
e = window.event;
}

arrowUp = 38;
arrowDown = 40;
arrowLeft = 37;
arrowRight = 39;

switch( e.keyCode )
{
case arrowUp:
//Do something
break;
case arrowDown:
//Do something
break;
case arrowLeft:
//Do something
break;
case arrowRight:
//Do something

document.onkeyd own = keyHandler;

ok, thanks, that works. the reason I was thinking it should click a certain
link on the page is cuz php is writing out the link for me, and will be
different each page. is there any way for javascript to 'click ' a link?

I'm just having php write out this javascript you gave me, so my problem is
solved without the < javascript 'click ' a link> question.

Easiest way to do it is probably change the document.locati on:

case arrowLeft:
document.locati on.href = "page1.html ";
break;
case arrowRight:
document.locati on.href = "page3.html ";
break;

(snip)

Except that it's *window*.locati on. document.locati on is deprecated,
although many user agents seem to have mapped it to window.location (in
other words, it works) - but it's still incorrect. btw,
document.locati on is now document.URL.

yeah, that's what I did. uh, except I forgot the .href, seems to be
working, though...I used window.location actually. pros and cons?

According to David Flanagan (JavaScript: The Definitive Guide,
O'Reilly):

In addition to its properties, the Location object can be used as if it
were itself a primitive string value. If you read the value of a
Location object, you get the same string as you would if you read the
href property of the object (this is because the Location object has a
suitable toString() method). What is far more interesting, though, is
that you can assign a new URL string to the location property of a
window. Assigning a URL to the Location object like this has a very
important side effect: it causes the browser to load and display the
contents of the URL you assign (this side effect occurs because the
Location has a suitable assign() method).

While you might expect there to be a method you can call to make the
browser display a new web page, assigning a URL to the location
property of a window is the supported technique to accomplish this.
