I've only got options to inspect html and css, the script tab shown in the docs is missing.
There was something wrong with Window's updater, IT ended up re-imaging the entire computer. Unfortunately the specific answer here will remain a mystery.

This website (www.samy.pl) uses some technique so that no one can inspect the code (Ctrl+Shift+I) or view source (Ctrl+U). It can detect if you have opened the console or inspector the code automatically changes.
How this is possible?
You could always save the website.
In chrome open the menu -> more tools -> Save page as..
You should be able to run the html file in chrome, and use Dev Tools without it blocking you.
There is a console "clearing" API that is mentioned in this answer.
Here's what I think is happening:
First, I think Google Chrome DevTools emits an event when it is open/launched.
The page author listens for this 'launch' event with the following handler logic:
Run a chrome.devtools.inspectedWindow.eval DevTools inspection API
Set document.body.innerHTML to the winky-face div
Also, a setInterval that executes a console.clear() before the console.log() of "no source for you".
I also inspected the EventListeners tab of Chrome DevTools while reading the "no source for you"-page.
Unfortunately, the two event listeners you can view don't seem to do anything useful:
one returns false
the other wires together forms and their associated submit actions.
Hope this helped
hahaha, this is a good one, you should not expect less from samy!
Now I see why people think it is the wrong answer (the source get replaced if you do otherwise)
1.Navigate to site with inspector open there you end up with "No source for you! You found easter egg #7."
2.and then check the source to find Easter egg #2:
view-source:https://samy.pl
you will see:
/*
No source for you! Easter egg #2
*// AFTER SOME LONG WHITE SPACES HERE /.source.replace(/.{7}/g,function(w){document.write(String.fromCharCode(parseInt(w.replace(/ /g,'0').replace(/ /g,'1'),2)))});
This is the way he loads the site(by injecting js), by replacing two type of white spaces for 1 and 0 and parsing that to char code by some regex and then that to string of course :D
https://de.wikipedia.org/wiki/Whitespace_(Programmiersprache)
If you paste that part to a js console, you will get the tags that loads the page.
ps. to see the rendered source, just load the page normaly and hit F12 after disabling javascript.
Have fun!
Create an index.html somewhere, containing an <iframe src='https://samy.pl/'>. Load it in your browser and then open devtools. You will see the source inside the iframe.
Update:
Go to view-source:http://samy.pl which is the link of what the view source right click brings you to. It only works on Chrome I think.
If you are using chrome, go to the menu at the top right. Then go to more tools, and click developer tools.
After a lot of tinkering and speculating together, my roommate succeeded in the end with quite a naïve approach.
Simply open the Chrome devtools and copy out the source before it gets replaced. Giving Chrome processes low priority and doing some heavy-lifting with your CPU (compilation or other) helps.
Chop, chop.
Ah! I have found an extremely easy way to do it.
1. Open Firefox (Chrome only shows you part of it).
2. In the URL bar, type in javascript:alert(document.documentElement.outerHTML);
3. Press Enter.
4. Voilà!
New Way to find the source code! But its complicated!
Open a new tab.
Open Devtools (Inspect Tab)
Click On Toggle Device toolbar (the mobile like icon)
Click on "No Throttling" to slow down the page loading time
Select "Low - Tier Mobile"
Open the page!
When you see the icons appear on the page, you can now see the source code! :)
sorry very late
but i think i have the answer
He used this node package
to which he has contributed and forked too
the package docs say that it wont work if the devtools are undocked
You can simply use the developer tools in almost all the browsers. Just Press F12 and the developer tools section will be there.
Thanks
I'm debugging some 3rd-party minified Javascript that somewhere is triggering a browser page refresh. However, I can't figure out what part of the code is causing the refresh.
Is there a way to put a breakpoint in Chrome that will be hit just before a page refresh so I can inspect the call stack to see what caused it?
Try this:
Open your Chrome Dev Tools
Navigate to the "Sources" tab
On the right panel, expand "Event Listener Breakpoints"
Expand the "Load" tree
Check the beforeunload and unload options
See if that helps; screenshot below.
Edit: Alternately, if that doesn't work, you can use Chrome to search all loaded scripts for the code that might be responsible. There's apparently a lot of ways to refresh the page with JavaScript but they mostly have a few common strings like "navigator", "location", "reload", "window".
Finally, if there's a link to the same page you are on, it's possible some JS is triggering a click on it-- unlikely, but worth exploring if nothing else has worked thus far...
(Please excuse the formatting as I'm on mobile...)
NOTE: It seems occasionally, for reasons I don't yet fully understand, this solution fails to actually cause the debugger to pause; in this situation, I found that thorn̈'s answer to this question did the trick for me.
In Firefox (not Chrome, it's important; UPD 2020: it now works in Chrome as well) Developer Tools, go to the console, enter addEventListener('beforeunload',()=>{debugger}), and execute your code. After the debugger stops at the debugger statement, look at the call stack. You'll see what triggered the event. Chrome didn't have it there.
At least, this worked for me.
In the devtool, network pane, toggle the "Preserve log", carefully check the initiator column.
You don't specify what's the 3rd party library does.
If it is a ui component like an ad or something similar, just place it inside an iframe with the sandbox attribute configured as you need.https://developer.mozilla.org/en/docs/Web/HTML/Element/iframe (Scroll down to the sandbox attribute section)
If it is something triggered by an event, just use (in chrome dev tools only) the getEveneListener() function and follow the listener trail... (hard, but possible)
Example:
The listener property will lead you to the actual functions that will be invoked. You can than search them in the obfuscated code and add debugger to understand it's purpose.
There are many other scenarios - if you can specify more.
I'm going to try to explain an issue that scratch my head...
When I open this website for the first time after opening Firefox (v43.0.3), the UI freeze during about 20 seconds and I don't undersand why. For example you can see that the background image appear after almost 20 seconds...
So, I used firebug net panel to try to understand where the problem comes from and I notice that the page load event is very long but I can't see any tasks executing during this event.
here is a screenshot of firebug Net Panel
When I open the website with Chrome it works fine, does someone has ever encounter that kind of problem ?
I hope that makes sense, thank you in advance.
You're making 31 requests (according to my NET panel - FireBug) which add to 323ms (at least in my case). Your background image is loading ~1s after. Maybe if you'd try to reorganize all that sprites you're requesting into less files - but it seems fair as loading time for me.
I once had a problem with Firebug itself. I had to turn it off and\or uninstall to get the page load normally on Firefox.
In my case it was an effect of problem between Firebug and Telerik Kendo JS Library.
Maybe you have a problem similar issue.
Thanks for your answers, indeed it seem's to comes from my firefox configuration or addons/plugins.
I use a Firefox pre-configured by my socity, so I installed a portable firefox to try if it works and the website is loading normaly.
Now I just have to find from whitch config or addons/plugins the problem comes from, thanks again !
The current project I am working on builds a page's javascript code based on some conditions. All the code works but when I go to the Developer Tools to see it, it is not showing. Or more like it is truncated and 3 dots added at the end.
It seems to be a change with the recent update. It is extremely annoying to not be able to see everything. Does anyone know how to make it show everything? If it helps, I'm working on a mac. Thanks.
Chrome Version 42.0.2311.152 (64-bit)
If you right click on the <script> tag and select "Edit as HTML", you'll be able to access the whole script, without the hyphenation.
I have a situation where I'm inserting javascript generated HTML code into a DIV. One would think this would be a no brainer, but for some reason, once the code is in, the status bar and tab loading graphics start up in both browsers and never stop again. The page continually appears to be loading data, but in reality, there's nothing more to load. Any idea why this may be happening? Solutions? I appreciate any help. Thanks!
Install the Firebug plug-in for Firefox. Open it up and got to the NET tab. That will allow you to see your network activity. Something on the server may be stalling. This will help you find it.
