Codio has a cool feature which I think is called Guide Throbber. When you log in for the first time you'll see various throbbing buttons around the page which act as 'help hints'. Clicking one of these buttons shows a popover that contains help text. Once a throbber has been clicked, it never shows again.
To the best of my knowledge, this feature is proprietary to Codio. Is there an open source jQuery or JavaScript version available?
I actually wrote the code for the throbber on Codio, and yes it is proprietary code, but there is no reason why we couldn't open source that, but no idea when I would get the time ;)
I don't know of any open source libs that can do this.

I recently downloaded Adobe Brackets onto my computer, but I soon realized I wasn't able to use jQuery in the same way I had before. The jQuery isn't functioning at all in the program and it is vital to the way the program works.

You can use developer tools in the browser to debug problems like this. For example, in Chrome:
Open the menu and choose More Tools > Developer Tools
Select the Console tab
Are there any errors listed in red? If so, what do they say? If the error links to a specific line of code, you can click it to go to that code. Often looking at the code and the error message together makes it obvious what's wrong. (And if not, you can post those two pieces of information in your question here so others can help you).
Select the Network tab, then reload your page to get fresh information
Click the filter icon (it looks like a funnel) and type "jquery"
Are any of the network requests in the list shown in red? If so, then the browser was unable to load jQuery – make sure you're using the correct URL. If there are no jQuery items showing up in the list, make sure yous HTML <script> tag has the correct syntax.
I was navigating on this page and clicked "Available for your computer" image.
Then a native browser popup that is like an alert was opened:
Please compare the one above with the following alert() that everybody knows:
How did they create such an alert?
alert seems not to support images, according to this question.
Is this possible to open with JavaScript? I guess yes, but how?
Is this cross-browser? On Firefox, I am redirected to Chrome download page.
NOTE: I DO know that there are a lot of JavaScript libraries to show alerts, but I DO NOT want to use any of them. I want a clear answer to my question.
Chrome has some specialized windows/popups available for it's own use .. things you can't do via regular JavaScript.
Other things you can't do via regular JavaScript are the
Enable Webcam prompt window
Download file window.
If you are trying to do something similar in pure JavaScript, this is a great little replacement:

This seems to be a "chrome specific" popup. The application you want to install by clicking on this button is a Google App, which install is handled by Chrome. I think.
Except Bootstrap-like modals, I have never seen such thing in Javascript before.
Check this if you want to implement such popups on your website:

instead of using alert . you can use any external plugin confirm box.Then you can customize your dialog box
As a freelance Wordpress developer I find myself thrown into projects where things are just 'broken' - with the problems regularly ending up being some kind of path issue/syntax error/etc in javascript.
I am in the situation right now where I am trying to get something that works in Site A to work on Site B. Basically the problem involves a mouse over event that causes a div with class name 'overlay-ico' to appear.
I'm sure there must be some kind of debug tool in Chrome, Firefox, etc that allows me to easily do this without reviewing all the source code?
Update:
I am familiar with being able to inspect the HTML (at least in a basic way), but I don't see how this shows me what would trigger an event to occur.
I am also know that there is a console, which as I understand it, only outputs errors, or something that has been explicitly directed to console output.
There must be somewhere in the code that is waiting for a mouse over event, that triggers 'overlay-ico' to appear. I'm sure I could do it if I did a search for 'overlay-ico' through all the source code - but I'm thinking there must be a faster way to find it.
In Windows, F12 opens the debug panel in most browsers.
In Chrome, you can inspect an element and then click into the Event Listeners tab in the right pane. That may show what you're after. It's hard to say without seeing it.
I saw How to hide html source & disable right click and text copy? . One of the answers say use ctrl+u to view the source. But, using shortcut.js I can override ctrl+u as well. How do I view source in that case.
There is no way to prevent this. Someone could easily download the page using a non-browser tool like curl or wget, or log all HTTP traffic with Wireshark.
Use this. http://www.fiddler2.com/
Depends on the browser, but you can go to View -> Page Source in most to view the source. You cannot override that, however.
Furthermore, it's considered bad practice, and someone could also just as easily override the functionality through a tool like Firebug.
You can't stop people. It will be passed over the network, and sniffable through Fiddler, or someone can use a text based browser, or disable Javascript entirely, or look through their cache folder for the files they downloaded from your site.
You cannot stop people from seeing your source.
Well it's not possible to prevent users from seeing your script. But what you can do is to make it mire harder that user quits trying after few common methods.
I recommend you to load an initial page. Then load the whole page by using ajax. You can show a friendly loading gif too. This technique has following adanages,
browsers don't show generated HTML. Developers knw how to see this. But Normal user will not find it easily
if any user just press Ctrl+u it'll show the initial page.
wget, curl tool will not work at the first time.
additionally you can obfuscate the main page (which you are going to load by Ajax).
It's nearly impossible to stop people fetching the HTML from your website. I don't see any reason you'd want to hide it in the first place anyway. Hiding something?
Want to view the source no matter what javascript is being used to hide it? cURL the page.
Even if you disable right-click, you can still do a snapshot by pressing the prt scrn key on your keyboard then pasting it into an image editor.
You can't disable it. There are ways to encrypt it, but way more trouble than it's worth.
It's impossible to hide the source, HTML and Javascript are interpreted languages, that mean the browser will "compile" the code on the clients machine.
I was looking for examples of Javascript games and I came across this. It looks like Flash. I tried looking at the source code, and all I see are a bunch of div tags, but not really any Javascript. I couldn't find the code that actually runs the game.
Is this Flash or Javascript? How can you tell?
It's Javascript.
When you right click it gives you the native browser context menu. Right-clicking anything in Flash will give you a Flash context menu. The only time that method fails is when you get no context menu at all.
Also, highlight the text "Press enter". It uses native text highlighting.
As far as I know is impossible to hide the typical secondary flash context menu telling the version, etc...
I found is using a core.js javascript
Hope it helps.
You can try to disable the plugin of shockwave flash from browser's options. Then refresh page and see, whether 'target flash' disappears. If so then it was flash.
