using a variable in href tag?

I use a browser based system of checking procedures, written in html and javascript.

I’m doing a new one where I have a few <select> tag options.
I want to use these with onchange functions, to build up a variable that contains a url, and use that variable in a link lower down the page.
I can do the onchange functions I’m sure, already using something like that, but I’m failing to get the link to work.

Done some googling and seemed to be straight forward, but the hits I found don’t seem to work for me.

Just to get going I had this on the head:
JavaScript: 
<script>
<!--
function Page(){
  location.href="[URL unfurl="true"]www.google.com";[/URL]
}
// -->
</script>

Then in my <body>

I have:
HTML: 
<td width="20"><a href="javascript:page()" target="new2" style=""><img src="Checking_Images/info_icon_red.jpg" border="0"></a></td>

All that happens is a blank tab opens, url is “about:blank”

I’m using firefox 13 on windows 7 64bit.

Where am I going wrong?

javascript is case sensitive, "Page" and "page" are NOT interchangeable.

Oh and href is a attribute of an anchor opening tag NOT a tag itself.

The usage of the javascript: protocol is considered a bad practice. That is placing an href that's not really a valid location is never a good idea.

Other than that, the target attribute is messing with the JS in that it opens the new page, but prevents the JS from actually running, since the function does not exist in the new opened page, but in the originating page only, so it can't be accessed.

If you want to open a new page you'll need to do it from the Javascript code rather that on the link itself.


Code: 
[COLOR=#990000]<[/color]a href[COLOR=#990000]=[/color][COLOR=#FF0000]"#"[/color] onclick[COLOR=#990000]=[/color][COLOR=#FF0000]"return Page();"[/color][COLOR=#990000]><[/color]img src[COLOR=#990000]=[/color][COLOR=#FF0000]"Checking_Images/info_icon_red.jpg"[/color] border[COLOR=#990000]=[/color][COLOR=#FF0000]"0"[/color][COLOR=#990000]></[/color]a[COLOR=#990000]>[/color]
Code: 
[b][COLOR=#0000FF]function[/color][/b] [b][COLOR=#000000]Page[/color][/b][COLOR=#990000]()[/color][COLOR=#FF0000]{[/color]
  window[COLOR=#990000].[/color][b][COLOR=#000000]open[/color][/b][COLOR=#990000]([/color][COLOR=#FF0000]"www.google.com"[/color][COLOR=#990000],[/color][COLOR=#FF0000]"new2"[/color][COLOR=#990000]);[/color]
  return [red]false[/red];
[COLOR=#FF0000]}[/color]

schoolboy error corrected, and anchor semantics noted, thanks.

Corrected case, still the same.

ah vacunita you posted while I was replying.

That looks good. I'll try that right now thanks.
I was wondering after I posted if the target might be an issue.

Wow! I'm impressed :)

Usually when I correct things like that, some take umbrage at it as being a personal insult to their intelligence.

Which of course it is not intended as such. So thank you, for restoring the balance somewhat.

If I felt I was in the right I would argue to the death :)

However, what umbrage can I take from being accurately corrected? :)
