I remember several years ago that I was able to save a remote JavaScript file from a website onto my local in Chrome Debugger, make a few code adjustments, and refresh the page so Chrome will be reading the local copy of the JS file. I am wondering if this feature is still available, and if so how am I able to use it?
I know that I can add breakpoints to achieve something similar. I have followed a few guides, but none of them was able to achieve what I want:

It looks as though you can only achieve this when you are using a local server. According to the Stage persisted changes section of the API:
If you are mapping files from a remote server instead of a local server, when you refresh the page, Chrome reloads the page from the remote server. Your changes still persist to disk and are reapplied if you continue editing in Workspaces.
It seems you could achieve what you want if you use Fiddler AutoResponder:
Fiddler's AutoResponder tab allows you to return files from your local disk instead of transmitting the request to the server.

When I upload any changes in javascript files to my deployed site on Google cloud compute engine, the changes do not show up right away, if I load the js files in browser. The changes are physically there, validated by RDPing to the server. B
These changes sometime take 6 to 8 hours to show up in browser, and sometimes show up sporadically. What can I do to ensure that my changed js files take effect immediately on load?
I dont face this problem when I upload on my test server, which is not under cloud. Happens only on the google cloud server.
Try opening your builtin browser debugger (for example right-click on your page, if using Chrome, and click "Inspect"). Now select the Network tab. Now reload. Now look at the sizes of the files. If they are very small, then probably the browser loaded cached copies. You can verify this by checking the "Disable cache" option in the Inspector.
If it works correctly and the file updates right away when you have the browser cache disabled, then you need to investigate with your web server software to see how to cause it to invalidate caches. One mechanism you can look into is called "ETags."
What worked was invalidating the cloud cache for the file. Lesson learnt: always add version numbers to your js files.
I am editing files through FTP connection. The changes are not reflecting on the browsers. I have followed instructions of using key combinations such as Ctrl and F5 keys, to clear cache but for some reason nothing is happening. So the server runs on an Ubuntu. I am using an FTP connection to edit and view the files. Do I need to do something server-side to clear or turn the development mode on? Considering I have an access to the server. I have been googling and on 10-hour coding but I could not get this one to work. It's my firs time to have an access, too, if that should help.
Try restarting the server.Also ensure that the changes that you are doing are reflecting when you reopens the file using FTP connection.
Please hear me out before you start crying security issues.
This is for an intranet application, hence I have full range to install any plugins or change any security permissions to suit.
What I want is for them to go to a webpage and click a link to download a file, such as a Word Document. This gets transferred to local storage of some kind (sandboxed if need be) and then is opened in word as a regular file.
When they click save, JavaScript or something will pickup the file is saved or the program is no longer accessing it and can be actioned upon, such as uploading back up to the server.
Is there any way to do this. I have looked at IndexedDb, WebStorage, HTML5 FileSystem API but I am new to all and don't see a way to do this.
I am open to coding any needed plugins as long as you don't mention Flash. The main issue I am coming across is opening a file downloaded into some form of local browser and then opening it via a desktop application, e.g. Word.
Any help, greatly appreciated.
After much research the only way to do it is with a plugin. IndexedDB, FileSystem API or WebStorage can not access the local file system. Which is good.
Silverlight is a good option for intranet and .NET, which is what I have chosen to go with.
Silverlight 5 in full permissions with a file watcher. The file watcher can be accomplished with this method: Is there an alternative to accomplishing what the FileSystemWatcher does in Silverlight?
Is there any client-side script that would be able to make changes to a file on the hosts computer? (Intention stated below)
I am creating a packaged app for chrome which can show some online data, and make it available even when offline.
There is a certain thing, for e.g. 'a webpage' i want to show/store (but i cannot get/read its contents due to it being on different origin). To show when online, i can use iframe, but am unable to preserve it for offline.
So i thought i could make an appcache (manifest within the application package) which will cache the file, and on press of an update button a script would run which would make some change to the manifest which would force the cached resource to be reloaded.
I searched a lot, but no results.
Any suggestions as to how it can be done. Or any other way to get it to work?
I don't think so. This could be a huge security problem if it existed.
If you had to, you could send an ajax request to the server to create a file it creates with the current prices, and add it to the appcache file.
Here is a link to another SO quesitob that has a list of APIs you could use to get your stock price.
Webservice to get stock quotes?
There's this website which has a javascript method in it that downloads a file. To call this method you have to set what language and serial number you're looking for and when that's done, the file is being generated according to the specified information you've just stated and then the file is being downloaded. Does anyone know how to specify this information, then send it and then download the file without going to this website?
Thanks in advance, Steve-O
If you use any tool that shows you what actual networking happens, you can discover the specific web requests that downloads the file. Chrome has those tools built in. The Firebug add-on adds those tools into Firefox. There are also apps that record all networking to/from the browser such as Fiddler which can be used to sleuth on the networking being done.
Of course, there may also be some authentication going on (a log-in, some cookies, etc...) that might be required, but all of that is visible with the right developer tools. Once you see exactly what is being sent over the wire, it's usually not hard to send that same request without a browser or without visiting that web page. If login credentials are required, that will still be required, but even that can be provided without a browser (e.g. from a server-side script).
JavaScript, as of the moment, can't download files. So how files gets downloaded? Well, the developer redirects the browser to a URL using
location.href = 'http://site.com/download.zip';
When the browser is redirected to this URL, it can't open the file, so it downloads it.
You need to determine that URL the browser redirects to. There are many ways to do that. One that comes to mind is the Fiddler app that records each HTTP request and thus can give you the URL.
My guess, however, is that the URL is generated on the fly. You need to study the JavaScript in this case and see the required mechanism to make the server generates the URL.
