Well, using HTML5 file handlining api we can read files with the collaboration of inpty type file. What about ready files with pat like
/images/myimage.png
etc??
Any kind of help is appreciated
Yes, if it is chrome! Play with the filesytem you will be able to do that.
The simple answer is; no. When your HTML/CSS/images/JavaScript is downloaded to the client's end you are breaking loose of the server.
Simplistic Flowchart
User requests URL in Browser (for example; www.mydomain.com/index.html)
Server reads and fetches the required file (www.mydomain.com/index.html)
index.html and it's linked resources will be downloaded to the user's browser
The user's Browser will render the HTML page
The user's Browser will only fetch the files that came with the request (images/someimages.png and stuff like scripts/jquery.js)
Explanation
The problem you are facing here is that when HTML is being rendered locally it has no link with the server anymore, thus requesting what /images/ contains file-wise is not logically comparable as it resides on the server.
Work-around
What you can do, but this will neglect the reason of the question, is to make a server-side script in JSP/PHP/ASP/etc. This script will then traverse through the directory you want. In PHP you can do this by using opendir() (http://php.net/opendir).
With a XHR/AJAX call you could request the PHP page to return the directory listing. Easiest way to do this is by using jQuery's $.post() function in combination with JSON.
Caution!
You need to keep in mind that if you use the work-around you will store a link to be visible for everyone to see what's in your online directory you request (for example http://www.mydomain.com/my_image_dirlist.php would then return a stringified list of everything (or less based on certain rules in the server-side script) inside http://www.mydomain.com/images/.
Notes
http://www.html5rocks.com/en/tutorials/file/filesystem/ (seems to work only in Chrome, but would still not be exactly what you want)
If you don't need all files from a folder, but only those files that have been downloaded to your browser's cache in the URL request; you could try to search online for accessing browser cache (downloaded files) of the currently loaded page. Or make something like a DOM-walker and CSS reader (regex?) to see where all file-relations are.

I am trying to rename a file when downloading it from <a> tag.
Here a simple example:
Download Stackoverflow Logo
As you can see, it never downloads the file with stackoverflow.png name, it does with default name though.
Nevertheless, if I download the image and tried to do the same with a local route, it renames the file properly.
Another example:
Download Stackoverflow Logo
The example above works properly.
Why download html attribute only works using local routes?
Thanks in advance!
The attribute download works only for same origin URLs.
By the way, you really should learn to use proper terminology, or else people won't understand you:
<a href="https://i.stack.imgur.com/440u9.png" download="stackoverflow.png"> is a tag, specifically, an opening tag;
download is an attribute;
stackoverflow.png is the value of the attribute;
https://i.stack.imgur.com/440u9.png is a URL, sometimes called an URI or an address.
The entire construction Download Stackoverflow Logo is an element.
A "route" is something else entirely, and has no relationship with HTML.
I couldn't find any info of it, but seems like external resources aren't allowed renaming.
Have a look here, there's an example linking to google image and that doesn't work either - seems like the specs have changed along the way.
This is a security measure applied to cross-origin download requests where the server hosting the download does not use HTTP headers to explicitly mark the file as being for download.
From the HTML specification:
If the algorithm reaches this step, then a download was begun from a
different origin than the resource being downloaded, and the origin
did not mark the file as suitable for downloading, and the download
was not initiated by the user. This could be because a download
attribute was used to trigger the download, or because the resource in
question is not of a type that the user agent supports.
This could be dangerous, because, for instance, a hostile server could
be trying to get a user to unknowingly download private information
and then re-upload it to the hostile server, by tricking the user into
thinking the data is from the hostile server.
Thus, it is in the user's interests that the user be somehow notified
that the resource in question comes from quite a different source, and
to prevent confusion, any suggested file name from the potentially
hostile interface origin should be ignored.
How do I find the filename of an website I am inspecting with Firebug? As example when I look on http://example.org/ I can view inspect the Element, I see the whole html structure but I didn`t find the filename. I am searching for index.html or something in that way. Maybe this is an analog question, but I am not sure, because he/she is working with php. LINK
I know there are some solutions with Dreamweaver or other tools but I am searching for an easy way to figure that out with Firebug or an free Browser Add-On. I Hope you have a solution for that.
The URL you entered is the one that usually returns the main HTML contents. Though on most pages nowadays the HTML is altered using JavaScript. Also, pages are very often dynamically generated on the server.
So, in most cases there is no static .html file.
For what it's worth, you can see all network requests and their responses within Firebug's Net panel.
Note that the URL path doesn't necessarily reflect a file path on the server's file system. It is depending on the server configuration, where a specific URL maps to in the file system. The simplest example is the index file that is automatically called when a domain is accessed. In the case of http://example.org the server automatically loads a file index.html in the file system, for example.
So, in order to get the file name on the file system, you need to either check the server configuration or the related access logs.
Dear Haskell community I have written my first gui application and decided to use
threepenny-gui to do so.
The task is the following search the files in a given folder for matches and provide links to open those files. In addition I made nice parse and render function as the files (mostly) have a special formatting.
But now I have stumbled upon a problem - most browsers prohibit links to local files by href="file://localhost/home/user/folder/file.pdf" being opened, for security reasons, which I do understand and find completely sensible.
I tried to use href="./file.pdf" when the program and the file are in the same folder, which also doesn't seem to work.
The code of the whole application is available at github/epsilonhalbe, I run it in a folder and access it via a browser at localhost:100000
The HTTP server provided by threepenny-gui will serve up static content from the directory you specify in tpStatic. Put your files in that directory, and make your links' paths be relative to it, and you'll be good to go!
As of threepenny-gui-0.4.*, there are also two functions loadFile and loadDirectory that can be used to serve a local file or directory at an automatically generated URL. This can be useful if the tpStatic field is not enough.
Basically, I'm creating a webpage filled with images of movie posters that link to video files, as a means of making a more visually-appealing form of my local video library.
I'm using
<a href="C:\blah\movie.mkv"><img src="poster.jpg">
It works exactly how I want, HOWEVER, it opens the file in the browser rather than opening it in its default program, as I would like. I would like each link to open the file in the program titled "VLC Media Player", as specified in Windows for each of their filetypes.
Let me know how I can do this (in the simplest form--I'm not too smart :P)
Thanks!
If you are creating web pages on your local system for you own use then you may want to consider looking in to a WAMP server setup. This uses php and should allow you to call VLC using the exec command. Would take some learning however.
There is very little you can do to control how a client will handle a resource.
You can use the Content-Disposition HTTP response header to state that the resource is an attachment (and thus recommend that it be downloaded instead of opened).
Content-Disposition: attachment;filename="movie.mkv"
You can't, however, stop browser native support or a plug-in from handling something instead of having it open in a separate application (let alone cause it to be opened in a specific application).
If the browser is configured to open video files internally, then nothing the author of a website can do will make it switch to using a application instead.
Right now I have FILE to allow users to download a file. I don't like that because it forces them to leave the current page and have to reload it (which takes a few seconds) when they want to go back
What is the easiest way to have users download a file?
Have the server send a Content-Disposition: attachment header for the resource in question. It'll then be presented to the user (if they have a sane browser) as a file to "save", rather than as a new page.
For certain types of resources this may mean you write a proxy script in PHP, or perhaps you can configure your webserver to do it.
Use this method:
FILE
The most reliable way to force a download without a server-side solution is to ZIP the file and then link to this archive. Provided that there aren't any limitations on using ZIP files almost every web browser I've encountered will download the file to the user's computer.
If you don't have server-side support, which I am just assuming because you're asking about the HTML and not a scripting language, you cannot always make a file download form the browser. This is because not every web browser is configured the same and the default application on the user's computer may also be set to something you can't predict.
Also, you should use the linking method that #craig1231 suggested so that the file download request is happening in a new window.
FILE
This will cut down on some of the time needed to refresh pages and, in most cases, when the web browser encounters a ZIP file as the URL of the window it will close the window once the file starts to download.
