How can I create a directory chooser in html page.
If I use input file element I can select file only, but I need to select directory instead.
I need to do this beacause the user should select a right path inside his computer.
Any solutions ?
Try this, I think it will work for you:
<input type="file" webkitdirectory directory multiple/>
You can find the demo of this at https://plus.google.com/+AddyOsmani/posts/Dk5UhZ6zfF3 ,
and if you need further information you can find it
here.
Can't be done in pure HTML/JavaScript for security reasons.
Selecting a file for upload is the best you can do, and even then you won't get its full original path in modern browsers.
You may be able to put something together using Java or Flash (e.g. using SWFUpload as a basis), but it's a lot of work and brings additional compatibility issues.
Another thought would be opening an iframe showing the user's C: drive (or whatever) but even if that's possible nowadays (could be blocked for security reasons, haven't tried in a long time) it will be impossible for your web site to communicate with the iframe (again for security reasons).
What do you need this for?
As of 2022 there is now a directory picker API:
https://developer.mozilla.org/en-US/docs/Web/API/Window/showDirectoryPicker
async function getDir() {
const dirHandle = await window.showDirectoryPicker();
// run code for dirHandle
}
In case if you are the server and the user (e.g. you are creating an app which works via browser and you need to choose a folder) then try to call JFileChooser from the server when some button is clicked in the browser
JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory(new java.io.File("."));
chooser.setDialogTitle("select folder");
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
chooser.setAcceptAllFileFilterUsed(false);
This code snipped is from here
This is my solution. It is the same as the above answers but you should notice that webkitdirectory = "true".
<input id="design" type="file" webkitdirectory = "true" directory/>
I did a work around. I had a hidden textbox to hold the value. Then, on form_onsubmit,
I copied the path value, less the file name to the hidden folder. Then, set the fileInput box to "". That way, no file is uploaded.
I don't recall the event of the fileUpload control. Maybe onchange. It's been a while. If there's a value, I parse off the file name and put the folder back to the box. Of, course you'd validate that the file as a valid file.
This would give you the clients workstation folder.
However, if you want to reflect server paths, that requires a whole different coding approach.
This isn't provided by HTML because of the security risk. <input type='file' /> is closest, but not what you are looking for.
If you're still using IE11 on Windows 10, you may try this example that uses an ActiveX control to achieve what you want.
Again if the OS is Windows, you can use VB scripts to access the core control files to browse for a folder.
If you do not have too many folders then I suggest you use if statements to choose an upload folder depending on the user input details.
E.g.
String user= request.getParameter("username");
if (user=="Alfred"){
//Path A;
}
if (user=="other"){
//Path B;
}

I am using VW7.8/Jun789 JunFileDialog for a file save as and want to remember/set the selected directory for next time. I am following JunFileDialog class example5. I suppose doing so in the onAccept: block should be possible, but so far I've had no success.
I'm having trouble understanding where or how to set the initialDirectory other than as per the example in the JunFileDialog>>request: messageString initialDirectory: directoryFilename initialFile: filenameString fileTypeMenu: aMenu initialFileType: fileType onAccept: acceptBlock onCancel: cancelBlock.
Is there a better file save dialog to use?
you can use VisualWorks' Dialog class. On class side it has the "file name dialogs" protocol. There you can find methods like #requestFileName:default: or #requestNewFileName:default:. Both should display a native dialog on Windows and Mac OS X which defaults to the last opened folder.
I am able to generate public URLs for iCloud files. e.g. https://www.icloud.com/documents/dl/?p=3&t=BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
Accessing such a URL from a browser, I see a landing page, and shorty afterwards the file downloads automatically. Fine.
However, I want to be able to download this file from my iOS app (with NSURLConnection). How can I do this? Maybe...
a) process the html headers to somehow determine the direct URL?
b) intercept the redirect/refresh that triggers the download on a browser?
c) somehow imitate a browser in order to trigger a download?
Thanks
PS. please give me the idiot's answer- I'm clueless about html etc.
Here is the html response I'm getting for the indirect URL above:

As of July 2012, the following seems to work. But there's no guarantee that apple won't change their scheme for generating these, and it's possible that they would regard this as a private API and reject your app. So use at your own risk.
The URL has two important parameters, p and t. The first seems to identify a server, while the second identifies the actual file. The direct download link is made by plugging these values into this URL:
https://p[p]-ubiquityws.icloud.com/ws/file/[t]
Looking at your example:
https://www.icloud.com/documents/dl/?p=3&t=BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
p is 3, and t is BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA. So your direct download link would be
https://p3-ubiquityws.icloud.com/ws/file/BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
Whenever I've published a link to iCloud, p has been 01; so it's possible that you might need to zero-pad your value in which case your URL would be
https://p03-ubiquityws.icloud.com/ws/file/BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
It would be great to know whether that's necessary.
In iCloud Drive / iOS8 the links are different, but you can still get a direct link to the files.

Save the text between '?u=' and '&uk=' as a NSMutableString
Save the information after 'uk=' and 'f=' as NSStrings
In the first string replace the text '${f}' with the 'f=' string and replace the text '${uk}' whith the 'uk=' string
If you need the files size for any reason, it's the number after 'sz=', but this is not needed for the final link
Voila, here is your direct link to the file:

It looks like the heavy lifting is done by the file referenced there:
https://www.icloud.com/applications/documents/download/en-us/1FCS22.32292/javascript-packed.js
I'd start there looking for the file name etc.
I'm getting some very strange behaviour from a file input element in both Chrome and Opera (possibly more, haven't tested).
I have the following HTML:
<div id="profileImgContainer" class="formFile">
<label>Profile Picture</label><div>
<input type="text" id="profileImgText"><input type="button" value="Choose File" id="profileImgButton">
</div>
<input type="file" id="profileImg" name="profileImg">
</div>
And the following jQuery to get the file input's value and put it in the (visible) textbox. The actual file input is hidden.
$(".formFile input[type='file']").live('change', function()
{
$(this).parents(".formFile").find("input[type='text']").val($(this).val());
});
I've made a JSFiddle for you try out. In Firefox, the text box happily takes the filename (don't care about the path) of the file element. In Chrome and Opera, however, when a file is selected the file path in the visible text box changes to C:\fakepath\[filename] where [filename] is the name of the file chosen. This path is obviously fake but what I want to know is why it's changed to it, and whether the file in the hidden upload element will still upload fine. I'm guessing it's a security feature, but I may be wrong.
This is one attempt to mitigate the security issues you get from allowing arbitrary foreign code to run in your browser: The script (which we assume could come from a malicious attacker) does not get to see (and possibly communicate back via AJAX) information about your local files.
Imagine what could happen if a script could just freely set file uploads and submit forms.
This behaviour concerning file upload controls and scripting is mandated by some sort of standard (I believe part of the DOM specification) for this very reason.
I just want to add a new answer for people facing this issue nowadays. Similar to one of the comments, it's better to use the input element itself. For example:
document.getElementById('file-input').files[0].path
This worked for me.
Similar solution for React:
const inpRef = useRef(null)
return (
<input type="file" onChange={() => {
const filePath = inpRef.current.files[0].path
// You can use more properties by looking at the files object
}} />
)
Am doing project in j2ee.I use Browse button. I need to fetch images/files from a folder inside my project folder, everytime.I wish to set my project's folder name as a default location for my browse button.How to do that?
am using tis following code in a jsp page:
and calling the value in servlet :
String image= (String) request.getParameter("img");
while browsing ,the whole path is getting displayed but only the name of the image is passing as value in the sevlet.How to get the entire path? or how to set my project folder as default location while browsing?
If this is rendering a standard
<input type="file".../>
Then you have no control over the default directory.
Using flash gains you a bit more control (filetype preset, single/multiple file selection etc.)
I'm not sure if Java Applets have more access/options, hopefully someone can advise.
PS. for the standard input tag, the browser will remember the last location you used, so you only need to navigate once, if you are uploading several files from the same directory.
I actually solved this problem with an interesting trick. Here's how...
Create an external vbscript include file called vbshelper.inc which contains the following code:
function stuffKeys(x)
Set wshShell = CreateObject("WScript.Shell")
wshShell.Sendkeys(x)
end function
Inside your HTML code header, place the following line as your first < Script> element...
< Script type="text/VBScript src="vbshelper.inc">
later, in your HTML code, create the button like this...
< input type="File" id="srcFile" onchange="go_do_something()" onclick="stuffkeys(' C:\Temp\*.txt~')">
Note the space before the C in ' C:\Temp*.txt~' and the tilde ~ after the .txt.
