Problem with onClick action syntax

[TrevBriggs]

I have code that builds a page of dog information which includes a "name=" tag for each dog. The code also builds an array of dog names ($dogname).

The following code is then supposed to create a simple form allowing the user to select a name from a list and click the "Find" button to go to the appropriate tag.
Everything works as designed except the "find" function - I've spent many hours trying to get the syntax of this right without success. I've tried building the input button code both inside and outside the PHP. Here's the current version:

<?php
echo "<form><label for='user'>Or, find a dog by name:</label>\n
<select name='findname' id='findname' class='selectOne'>\n
<option value=''>Select name</option><option value=''>---------------</option>\n";
sort($dogname);
foreach ($dogname as $thisdog) {
    echo "<option value='$thisdog'>$thisdog</option>\n";
}
echo "</select>\n";
?>
<input type="button" value="Find" onClick='location.href=document.referrer+ "#" + dogname.value';/></form>
 

The page as it currently stands can be seen at: http://www.greyhoundpets.com/Test2.php

Thanks for any help you can give.

instaed of dogname.value just use:

document.getElementById('findname').value

That worked! Excellent - you're a life-saver. Many thanks!

(I don't know why I didn't notice that dogname.value was obviously wrong!)

glad to hear that ;) ... to get help for such simple problems you could use the firebug-extension for firefox ... which i always would recommend to use for webdevlopment tasks ... it would have shown here for example that dogname.value is undefined ...

kind regards

Thank you - I'll definitely look into firebug.

I did make one change to the code. I found that the code worked as long as I went directly to my page by typing in the URL, but if I went to my home page first and then clicked the link to this page, when the "Find" button was pressed it took me back to the home page. I corrected this by changing "href=document.referrer" to "href=document.URL".

Thanks again for taking the time to help with this.

Wow - I've just looked at the firebug plug-in tool! What a fantastic resource - it will definitely save me a LOT of time. Thanks again for pointing it out to me.
