Javascript local -> online loading error?

@waffleApr 14.2006

When I run the following html on my computer everything works great.

[code] <html> <head>

</head> <body> <script type=”text/javascript” src=”md5.js”></script> <p><strong>Convert text to MD5</strong></p>

<form> Word: <br /> <input type=”text” name=”input” size=”40″ /><input type=”button” onclick=”hash.value = hex_md5(input.value)” value=”MD5″ /><br /><br /> MD5:<br /> <input type=”text” name=”hash” size=”40″ /></form><br /> </body> </html> [/code]

But when I upload the exact code to my web-server, the script does not appear to work at all. I honestly don’t know why this is happening. Yes, I uploaded the .js file with it and yes they are in the same directory. Sometimes it works right too. So I was thinking maybe it had to do with calling the javascript function right after calling to load it? I honestly don’t know what the problem could be. Any help would be greatly appreciateed.

@waffleauthorApr 14.2006 — #Okay, nevermind, it is fixed now. I used a direct link to the file on my server instead of a local link. For some reason that wasn't working somehow. Thanks for your help though. ?

@phpnoviceApr 14.2006 — #You mean you had a physical [U]path[/U] coded instead of an absolute or relative [U]URL[/U]? Physical path requests to the server from a client are normally not allowed. However, either an absolute (e.g., http://www.mydomain.com/folder/page.htm) or a relative (e.g., /folder/page.htm) URL should always work.

@waffleauthorApr 14.2006 — #No, I had /files/javascript/md5.js It wasnt working so I changed it to ww.url.com/files/javascript/md5.js and it worked fine. I'm not sure why as the file was in the main folder, but it's not really an issue now.

@phpnoviceApr 14.2006 — #No, I had /files/javascript/md5.js [/QUOTE]
OK. Seems to me I've seen this before, too. It would seem logical that one could specify a relative URL which starts with a forward-slash and expect that this means to start at the web site's root folder and work down from there. Instead, it seems you can only start such a relative URL from the folder in which your page lies. This means that if you must back up to a higher-level folder then you must use the ".." reference for as many times as needed.

Thus, if your page is in the root folder, your relative URL to the js file should be:

files/javascript/md5.js

If your page is one level down from the root folder, and not in the "files" folder, then your relative URL would be:

../files/javascript/md5.js

etc.

@waffleauthorApr 14.2006 — #I know how file structures work. It was in the root directory and it was a link to files/javascript/md5.js. The thing that confused me was that if I did
<a href="files/javascript/md5.js" title="JS Link">Javascript Link</a>
it linked fine to the javascript. But when i did

<i>
 </i>&lt;script type="text/javascript" src="files/javascript/md5.js"&gt;&lt;/script&gt;

It would not load the js. But it is fixed now with a direct link.
