I'd like to screate a link to my javascript functions, such that they do not appear in the page source code and users cannot tamper with them. I've noticed that other websites appear to be able to this usings commands such as:
[HTML]<SCRIPT src="folder/functions.js" type=text/javascript></SCRIPT>[/HTML]
However, when I try this it does not work. Can anyone explain what I need to do to make this work OR point me in the direction of a suitable tutorial to explain the issue.

This is a subject that is visited many, many times.
In short: you cannot effectively *hide* the JavaScript because it has to be readable by the browser - and the browser can only *see* what a human can.
What you've displayed in your post is that of external javascript, that is, a javascript file that is linked to from the file. Here is a tutorial on that.

Perhaps it's because the type attribute needs to be quoted:
[HTML]<script src="folder/functions.js" type="text/javascript"></script>[/HTML]
When you say it doesn't work, what do you mean? As explained above, you can't hide JavaScript source code. Sure, for someone who doesn't know any better, using external JS files will fool them, but there's a lot more savvy users out there. What are you worried about specifically when you mention "tampering" ?

That may be the first result on Google, but it's out of date. The Browser Compatibility notice at the top might've given a clue: NS4 and IE4 (eugh!). The only things wrong are that it uses the deprecated language attribute, uses capital letters (though that shouldn't be a problem in plain HTML), and uses the "javascript :" protocol in a link href. Thought I'd just point out :)

My apologies
:) It was late!
I wasn't aware there was anything wrong with using 'javascript : function()' in a href attribute?

No problem. You want reasons, you got them.

I generate my webpages from a database. A good many of my links are popup
links. For convenience I am using a javascript function to pop up the window
e.g.
popInternalWindow("Home");
popInternalWindow(pagename)
{
popupString = "<%=session("DomainName")%>" = "/" + pagename + ".htm";
pagename = window.open(popupString,pagename,'');

I would like to use the Link Target attribute, but am
inhibited by the likelihood of a newly opened browser window
completely hiding the Parent browser window. Thus offering
the illusion that you're still in the same browser, but the
Back Button no longer works.
I've done some experimentation and came up with the
conclusion that Microsoft's IE browser has a relatively
small likelihood of that happening, but that Netscape's

I have a layout which works perfectly. It is three column, the central
column is width:auto; with margins and the columns are absolutely
positioned at top:0px; left:0px; and top:0px;right:0px;
In the right column I have a javascript link which hides the column.
This is very necessary due to the width of content shown on the site at

a practical list of best practices that they could easily put to use.
The above URL is version 1.0 (draft) that resulted. IMO, it is not a

Hi,
Sorry to repost, but this is becoming aggravating, and causing me a lot of
wasted time. I've got a reasonably large mixed C++ project, and after a
number of builds (but not a constant number) linking (and sometimes
compiling) becomes immensely slow, and task manager shows that link.exe (or
cl.exe) is barely using any processor time, but an awful lot of RAM (around
150-200MB). I'm going to keep an eye on page faults since I can't...

VARIABLE SCOPE IN JAVASCRIPT

First off, what the heck is 'scope' (the kind that doesn't help kill the germs that cause bad breath)? Scope describes the context in which a variable can be used. For example, if a variable's scope is a certain function, then that variable can only be used in that function. If you were to try to access that variable anywhere else in...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
