javascript external file - call function fail

i just can't figure out this one. this is the web page file: http://lookaroundyou.net/test.php click on button and nothing happens.

i use same files on my localhost computer and alert pop ups? why? please

accessing ajax.js directly gives me forbidden message so i suppose it has something to do with permiss开发者_如何转开发ions? how to alte this?

many thanks

The problem is permissions here, when trying to load your ajax.js file I'm getting a 403-Forbidden, so the script never loads for my browser...which is what's causing the error.

Your page is at the root of the domain, so this doesn't make much sense:

<script type="text/javascript"  language="javascript" src="../ajax.js"> 

...that ../ shouldn't be there (it would be beneath the root of the site), make sure your path to ajax.js is correct.

Failed to load source for: http://lookaroundyou.net/ajax.js

Apparently, loading http://lookaroundyou.net/ajax.js isn't allowed on your server.

Maybe, it's in the wrong place since you're trying to load it via "../ajax.js" which means in the folder before your web folder, or totally absent.

http://lookaroundyou.net/ajax.js gives a 403 Forbidden HTTP status and the JavaScript file is not included. Check your server settings and/or .htaccess files.

Also why include ../ajax.js if you're already at the top level? It should be just ajax.js. But note that this is not the reason your script doesn't work because the browser is smart enough to look in the right place even with those extra ...
