Just curious, I can view the source of that web page just fine.. what exactly do you mean by you can't see it?

(btw.. many websites use the "no right click" script... but it's really, really easy to trick. Either A) Copy source and remove it, or B) when the "ok" box comes up, just hit space bar at the exact same time you right click, and kaboom, it works :) )

There's no way to block someone from taking your source code. The best you can do is make it ugly and hard to read :)

You can check out www.anti-leech.com, they claim to have anti source stealing stuff. But I was able to get past their demonstration pretty easy...

Mozilla, I clicked on this bookmark I whipped up a while ago just for sites like these:

javascript:window.open('about:blank').document.write('<pre>' + unescape((new XMLSerializer()).serializeToString(document).replace(/</g, '<')) + '</pre>')

IE, same thing:

javascript:window.open('about:blank').document.write('<pre>' + document.documentElement.outerHTML.replace(/</g, '<') + '</pre>')

Alternatively, I can remove the no-right-click script with this bookmark in Moz:

javascript:void(delete document.oncontextmenu);void(delete document.onmousedown);void(delete document.onmouseup);

Hit CTRL-A, then right-click and "View Selection Source".

A IE explorer bar add-on to see the source code of the current page:

A free add-on to disable right click block just clicking left & right buttons at same time (and other stuff): http://www.cs.huji.ac.il/~gadam/iemdl.htm

Besides, the poster apparently didn't read the "sticky" thread that covers this in detail.

There's a reason that these kind of threads are made sticky. If I was moderating this forum, I'd close this thread, since it's just going to get beat to death and this question has been answered probably thousands of times.

However, I like some of the newer, interesting ways of getting source code even easier. :)

I would just like to know WHAT IS THE FREACKING POINT in hiding the source code??? What is it that people are trying to protect??? If I can read the information posted, I can make use of it!!! If copyright notice does not stop me - nothing else will, even if I have to retype the content.
Please, do not tell me "I'm tryng to protect my layout". If you are still using HTML for layout, such layout is worth nothing. Layout information belongs to css file.
The only valid reason I can think of to hide source code is: it is so fugly, owner is ashamed of it.

well there are pictures and encrypted logins that are in my source.

Vladdy

01-05-2003, 07:18 PM

Logins belong to the server side. If you are trying to do some javascripting put it in an external file.
There is not much you can do about PrtScr or other screen capturing utilities. If you want to deter the ignorant from right-clicking on your images there are better ways that do not affect the rest of the users:

Many want to learn how to hide source immediately after they figure out how to steal it... Most I would say - why would a knowledgable web developer bother? There's few inept ones (that I know personally) who steal scripts and then have stupid no right click scripts in the pages.
This is not to accuse ccobra3000 of that. Protecting images is a big concern for a lot of people... however if you serve them on the web, consider them public property.

Heh... this seems awfully familiar... ;)

I don't see any reason to hide the source. As long as the browser has read it, there will be programs that can reproduce the sources (including external files). For every "no-right-clicking" image that popped up with an annoying message and an email which you never get a reply from, you get pissed and find ways around the right clicking just for the fun of it. There's no stopping anyone.

Code is just output of the mind; they can't steal your mind so who gives a rat's?

Let em have it I say; use philosophically-interesting variable names and make it easy to steal - like writing zen poetry inside your hifi;

Do it on the server so all they see is the output, not the actual program.

It doesn't matter because a creative mind is boundless - you can create anything, but a plagiarist can only steal what already exists ;)

Wow, that's a very accurate and elegant way to put it, brothercake. And so true. :)

I've said many similar things in the past, but I'm a bit more long-winded than you are. ;)

A plagiarist can steal your code, but if you're any good your code will improve, you will be using dynamic data, etc. - and there's no way a theif could ever keep up with that, since it would be a 24/7 job (and if you're using databases, they don't have access to the data that truly makes your site/application dynamic!).

That's why the internet is "open-source", anyway, is to share knowledge and ideas, not hide them! - and it's one of the things that truly makes this forum one of the best resources on the internet.

:D
