Can this be done?

[Anon]

Not sure if I have to use javascript or if I can use PHP:

I have an image that when the user clicks, I want to dynamically decide what page the href links to.
EXample:

<script language="JavaScript">
function setlink() {
var x;
x="result_b.php"; -- use logic to determine what page, x will return
return x;}

</script>

<a href=Javascript:setlink()><img src="../images/go.gif" width="38" height="35" border="0"></a></p>

right now, the code just puts the text (result_b.php) on a new page, instead of actually going to the result_b.php page.

thanks for you help
How should I do this or why is this not working?

Pretty much right for the most part as it stands. The problem is that instead of simply returning x from the JavaScript function you actually want the browser to go there.

Instead of having href="javascript:..." methinks better would be to drop the <a> tag completely and have an onclick= handler in the <img> tag [is this cross-browser (read: NS4) friendly?].

Then, in the function it calls, instead of simply returning x, call

window.location="http://www.whatever.foo/"+x

...or whatever the URL you want the browser directed to.

Needless to say, anyone browsing without Javascript will be left out in the cold by this.

What you're saying is that no one knows where that link will take them until after they click on it? Why do you have to dynamically create the URL when they click on the image? Couldn't you dynamically create the URL when you create the page?

This could be done on the server side with PHP and would work with any browser.
