how to activate javascript file from html page

236 New Member

Hi All,

The html page(see item a below) is calling javascript(item b below), but cant work as the page show blank. Not sure if the method of calling is wrong(in terms of default directory) or javascript is wrong.

using 127.0.0.1/htmlscript.html below to call the java script embedded in the following html script.

I am using apache server and apache server have error 304(not modified)

Been trying many methods for past 1 week...

Not sure where went wrong?

Thanks and Best Rgds,
Andrew

And a doctype will be needed (if you intend to support any version of Internet Explorer).

Hi Sir,

Something is missing and I tried many different ways and means including alert and still cant work. Please see below a)html and b)javascript. I activated the js script from default apache directory which is htdocs directory where I placed the javascript if you refer the my html above.

there is nothing missing ... it is just too much ... leave the script-tags out and drop those useless comment ... just the alert() should be left in the JS-file ... here is an example ...

Another thing to note: everything should be lowercase if you wish to comply with HTML standards. The 'language' attribute is deprecated (not needed or supported).

hi happyse27,

i just closed the following threads that are handling the same issue:

http://bytes.com/forum/thread851230.html
http://bytes.com/forum/thread852374.html

please try to keep one thread for a specific problem ... since otherwise it would lead to just spreaded information and answers ... i don't feel like merging all the threads since some different lines of code are posted there and some different hints and answers but as far as i could see the problem is always the same and so we should just use this thread here. i linked everything together so we could jump from thread to thread.

kind regards

Hi Sir,

Thanks and noted, sorry and apologize because I did that because I dont know if it belongs to javascript issue or html's therefore did double post. Anyway, I tried your method. But still the alert message below did not pop up... Checked apache access log is it error 500 and error 543. Kindly advise what is happening???

The example you given..
=============== ==

<html> 

    <head> 

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

and this is in the file foo.js:

alert('foo');
