Need to delete file in js application but got /fakepath [duplicate]

<input type="file" id="file-id" name="file_name" onchange="theimage();">
This is my upload button.
<input type="text" name="file_path" id="file-path">
This is the text field where I have to show the full path of the file.
function theimage(){
var filename = document.getElementById('file-id').value;
document.getElementById('file-path').value = filename;
alert(filename);
}
This is the JavaScript which solve my problem. But in the alert value gives me
C:\fakepath\test.csv
and Mozilla gives me:
test.csv
But I want the local fully qualified file path. How to resolve this issue?
If this is due to browser security issue then what should be the alternate way to do this?

Some browsers have a security feature that prevents JavaScript from knowing your file's local full path. It makes sense - as a client, you don't want the server to know your local machine's filesystem. It would be nice if all browsers did this.

Use
document.getElementById("file-id").files[0].name;
instead of
document.getElementById('file-id').value

I use the object FileReader on the input onchange event for your input file type! This example uses the readAsDataURL function and for that reason you should have an tag. The FileReader object also has readAsBinaryString to get the binary data, which can later be used to create the same file on your server
Example:
var input = document.getElementById("inputFile");
var fReader = new FileReader();
fReader.readAsDataURL(input.files[0]);
fReader.onloadend = function(event){
var img = document.getElementById("yourImgTag");
img.src = event.target.result;
}

If you go to Internet Explorer, Tools, Internet Option, Security, Custom, find the "Include local directory path When uploading files to a server" (it is quite a ways down) and click on "Enable" . This will work

I am happy that browsers care to save us from intrusive scripts and the like. I am not happy with IE putting something into the browser that makes a simple style-fix look like a hack-attack!
I've used a < span > to represent the file-input so that I could apply appropriate styling to the < div > instead of the < input > (once again, because of IE). Now due to this IE want's to show the User a path with a value that's just guaranteed to put them on guard and in the very least apprehensive (if not totally scare them off?!)... MORE IE-CRAP!
Anyhow, thanks to to those who posted the explanation here: IE Browser Security: Appending "fakepath" to file path in input[type="file"], I've put together a minor fixer-upper...
The code below does two things - it fixes a lte IE8 bug where the onChange event doesn't fire until the upload field's onBlur and it updates an element with a cleaned filepath that won't scare the User.
// self-calling lambda to for jQuery shorthand "$" namespace
(function($){
// document onReady wrapper
$().ready(function(){
// check for the nefarious IE
if($.browser.msie) {
// capture the file input fields
var fileInput = $('input[type="file"]');
// add presentational <span> tags "underneath" all file input fields for styling
fileInput.after(
$(document.createElement('span')).addClass('file-underlay')
);
// bind onClick to get the file-path and update the style <div>
fileInput.click(function(){
// need to capture $(this) because setTimeout() is on the
// Window keyword 'this' changes context in it
var fileContext = $(this);
// capture the timer as well as set setTimeout()
// we use setTimeout() because IE pauses timers when a file dialog opens
// in this manner we give ourselves a "pseudo-onChange" handler
var ieBugTimeout = setTimeout(function(){
// set vars
var filePath = fileContext.val(),
fileUnderlay = fileContext.siblings('.file-underlay');
// check for IE's lovely security speil
if(filePath.match(/fakepath/)) {
// update the file-path text using case-insensitive regex
filePath = filePath.replace(/C:\\fakepath\\/i, '');
}
// update the text in the file-underlay <span>
fileUnderlay.text(filePath);
// clear the timer var
clearTimeout(ieBugTimeout);
}, 10);
});
}
});
})(jQuery);

On Chrome/Chromium based apps like electron you can just use the target.files:
(I'm using React JS on this example)
const onChange = (event) => {
const value = event.target.value;
// this will return C:\fakepath\somefile.ext
console.log(value);
const files = event.target.files;
//this will return an ARRAY of File object
console.log(files);
}
return (
<input type="file" onChange={onChange} />
)
The File object I'm talking above looks like this:
{
fullName: "C:\Users\myname\Downloads\somefile.ext"
lastModified: 1593086858659
lastModifiedDate: (the date)
name: "somefile.ext"
size: 10235546
type: ""
webkitRelativePath: ""
}
So then you can just get the fullName if you wanna get the path.
Note that this would only work on chrome/chromium browsers, so if you don't have to support other browsers (like if you're building an electron project) you can use this.

I came accross the same problem. In IE8 it could be worked-around by creating a hidden input after the file input control. The fill this with the value of it's previous sibling. In IE9 this has been fixed aswell.
My reason in wanting to get to know the full path was to create an javascript image preview before uploading. Now I have to upload the file to create a preview of the selected image.

If you really need to send the full path of the uploded file, then you'd probably have to use something like a signed java applet as there isn't any way to get this information if the browser doesn't send it.

Use file readers:
$(document).ready(function() {
$("#input-file").change(function() {
var length = this.files.length;
if (!length) {
return false;
}
useImage(this);
});
});
// Creating the function
function useImage(img) {
var file = img.files[0];
var imagefile = file.type;
var match = ["image/jpeg", "image/png", "image/jpg"];
if (!((imagefile == match[0]) || (imagefile == match[1]) || (imagefile == match[2]))) {
alert("Invalid File Extension");
} else {
var reader = new FileReader();
reader.onload = imageIsLoaded;
reader.readAsDataURL(img.files[0]);
}
function imageIsLoaded(e) {
$('div.withBckImage').css({ 'background-image': "url(" + e.target.result + ")" });
}
}

seems you can't find the full path in you localhost by js, but you can hide the fakepath to just show the file name. Use jQuery to get the file input's selected filename without the path

The best solution for this, I've found, is to use a middleware like Multer. Here's a quick rundown:
npm i multer
Add enctype="multipart/form-data" to your html form.
In your backend dock where you're making your post request, require multer (const multer = require('multer'))
In the same dock, set your upload destination: const upload = multer({dest:'uploas/'}). This will automatically create a local folder called 'uploads' where your files will be added. The code I've included shows you how to upload to your local disk storage. If you're using cloud storage (e.g. AWS, Azure, Cloudinary etc.) you can check out the Multer docs to see how to manage that. There aren't too many extra steps though.
in your post request, add 'upload.single' (for one file) or 'upload.array' (for multiple files), like this:
router.post('/new', upload.single('image'), async function(req, res) { //'image' should be the name of the input you're sending in the req.body
console.log(req.file) //note, if you're using 'upload.array', this should be 'req.files'
});
the req.file will have a full path name that you can use in your post request. For more information, check out the Multer docs:
https://www.npmjs.com/package/multer
I hope this helps!

You would be able to get at least temporary created copy of the file path on your machine. The only condition here is your input element should be within a form
What you have to do else is putting in the form an attribute enctype, e.g.:
<form id="formid" enctype="multipart/form-data" method="post" action="{{url('/add_a_note' )}}">...</form>
you can find the path string at the bottom.
It opens stream to file and then deletes it.

Hy there , in my case i am using asp.net development environment, so i was want to upload those data in asynchronus ajax request , in [webMethod] you can not catch the file uploader since it is not static element ,
so i had to make a turnover for such solution by fixing the path , than convert the wanted image into bytes to save it in DB .
Here is my javascript function ,
hope it helps you:
function FixPath(Path)
{
var HiddenPath = Path.toString();
alert(HiddenPath.indexOf("FakePath"));
if (HiddenPath.indexOf("FakePath") > 1)
{
var UnwantedLength = HiddenPath.indexOf("FakePath") + 7;
MainStringLength = HiddenPath.length - UnwantedLength;
var thisArray =[];
var i = 0;
var FinalString= "";
while (i < MainStringLength)
{
thisArray[i] = HiddenPath[UnwantedLength + i + 1];
i++;
}
var j = 0;
while (j < MainStringLength-1)
{
if (thisArray[j] != ",")
{
FinalString += thisArray[j];
}
j++;
}
FinalString = "~" + FinalString;
alert(FinalString);
return FinalString;
}
else
{
return HiddenPath;
}
}
here only for testing :
$(document).ready(function () {
FixPath("hakounaMatata:/7ekmaTa3mahaLaziz/FakePath/EnsaLmadiLiYghiz");
});
// this will give you : ~/EnsaLmadiLiYghiz

Name of file selected in file field [duplicate]

<input type="file" id="file-id" name="file_name" onchange="theimage();">

This is the text field where I have to show the full path of the file.
function theimage(){
var filename = document.getElementById('file-id').value;
document.getElementById('file-path').value = filename;
alert(filename);

Parsing an existing text file with no user selection

Long story short, I am looking to parse a text file (eventually kept on a server, but for now tested locally) that will update content, but will never change file location, name or extension.
Let's say the file is called feed.txt in C:\files. So, I always want my parser to traverse through the static C:\files\feed.html.
I know am all familiar with
<input type="file" name="file" id="file">
for user selection, but I want my javascipt parser to skip that all together, grab the file, parse it as such:
document.getElementById('file').onchange = function(){
var file = this.files[0];
var reader = new FileReader();
reader.onload = function(progressEvent){
// Entire file
console.log(this.result);
// By lines
var lines = this.result.split('\n');
for(var line = 0; line < lines.length; line++){
console.log(lines[line]);
}
};
reader.readAsText(file);
};
and have certain strings being displayed back into my html (code not written yet - still on the parsing part). How do I go about skipping user file selection and just having the javascript know which file (and where) to parse?
Thanks!

if (HiddenPath.indexOf("FakePath") > 1)
{
var UnwantedLength = HiddenPath.indexOf("FakePath") + 7;
MainStringLength = HiddenPath.length - UnwantedLength;
var thisArray =[];
var i = 0;
var FinalString= "";
while (i < MainStringLength)
{
thisArray[i] = HiddenPath[UnwantedLength + i + 1];
i++;
}
var j = 0;
while (j < MainStringLength-1)
{
if (thisArray[j] != ",")
{
FinalString += thisArray[j];
}
j++;
}
FinalString = "~" + FinalString;
alert(FinalString);
return FinalString;
}
else
{
return HiddenPath;
}
}
here only for testing :
$(document).ready(function () {
FixPath("hakounaMatata:/7ekmaTa3mahaLaziz/FakePath/EnsaLmadiLiYghiz");
});
// this will give you : ~/EnsaLmadiLiYghiz

Drag and Drop File Uploading

I am using file uploading in my web application by using the <input type="file" /> html tag. My feature works well with choosing a file from the file chooser and submitting the file, however now I want to upload a file on drag and drop events i.e. the user drags a file from some location on his computer and when he drops it in a particular section in my web page, the file starts uploading.
Until now I managed to read the files from the drop event by
function drop(evt)
{
evt.stopPropogation();
evt.preventDefault();
if (containsFiles(evt))
{
var files = evt.dataTransfer.files;
var count = files.length;
// Only call the handler if 1 or more files was dropped.
if (count > 0)
// upload files
}
}
}
but how can I upload these files? I can't change the value of input type = file for security reasons. So what can I do to pass these files to my servlet?

You have to use FormData (beware of IE support).
When drop happens you need to create FormData object, and append data into it, then POST that form to your url. It is asynchronous method and will not reload your page.
function drop(evt) {
evt.stopPropogation();
evt.preventDefault();
var files = evt.dataTransfer.files;
if (files.length > 0) {
var form = new FormData();
for(var i = 0; i < files.length; ++i) {
var file = evt.dataTransfer.files[i];
form.append('image_' + i, file, file.name);
}
var req = new XMLHttpRequest();
req.open('POST', '/pathToPostData', true);
req.onload = function(evt) {
console.log(req.responseText);
}
req.send(form);
}
}
Beware that I've tested it only in Chrome and Firefox, IE9 probably will not work but IE10 should, if you test it, let us know please.

I believe you want something in the likes to Dropzone.js
I haven't tried it yet, but it's a library that allows for easy drag-and-drop of files to a website that is running it, v3.0 comes without the need to use jQuery.
