On Windows and with React: What can I do to get the full path of a browsed file? [duplicate]

How to get full path of file while selecting file using <input type=‘file’>
<input type="file" id="fileUpload">
<script type="text/javascript">
function getFilePath(){
$('input[type=file]').change(function () {
var filePath=$('#fileUpload').val();
});
}
</script>
but the filePath var contains only name of selected file, not the full path.
I searched it on net, but it seems that for security reasons browsers (FF,chrome) just give name of file.
Is there any other way to get full path of selected file?

For security reasons browsers do not allow this, i.e. JavaScript in browser has no access to the File System, however using HTML5 File API, only Firefox provides a mozFullPath property, but if you try to get the value it returns an empty string:
$('input[type=file]').change(function () {
console.log(this.files[0].mozFullPath);
});

So don't waste your time.
edit: If you need the file's path for reading a file you can use the FileReader API instead. Here is a related question on SO: Preview an image before it is uploaded.

Try This:
It'll give you a temporary path not the accurate path, you can use this script if you want to show selected images as in this jsfiddle example(Try it by selectng images as well as other files):-
JSFIDDLE
Here is the code :-
HTML:-
<input type="file" id="i_file" value="">
<input type="button" id="i_submit" value="Submit">
<br>
<img src="" width="200" style="display:none;" />
<br>
<div id="disp_tmp_path"></div>
JS:-
$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
$("img").fadeIn("fast").attr('src',URL.createObjectURL(event.target.files[0]));
$("#disp_tmp_path").html("Temporary Path(Copy it and try pasting it in browser address bar) --> <strong>["+tmppath+"]</strong>");
});
Its not exactly what you were looking for, but may be it can help you somewhere.

You cannot do so - the browser will not allow this because of security concerns.
When a file is selected by using the input type=file object, the value
of the value property depends on the value of the "Include local
directory path when uploading files to a server" security setting for
the security zone used to display the Web page containing the input
object.
The fully qualified filename of the selected file is returned only
when this setting is enabled. When the setting is disabled, Internet
Explorer 8 replaces the local drive and directory path with the string
C:\fakepath\ in order to prevent inappropriate information disclosure.
And other
You missed ); this at the end of the change event function.
Also do not create function for change event instead just use it as below,
<script type="text/javascript">
$(function()
{
$('#fileUpload').on('change',function ()
{
var filePath = $(this).val();
console.log(filePath);
});
});
</script>

You can't.
Security stops you for knowing anything about the filing system of the client computer - it may not even have one! It could be a MAC, a PC, a Tablet or an internet enabled fridge - you don't know, can't know and won't know. And letting you have the full path could give you some information about the client - particularly if it is a network drive for example.
In fact you can get it under particular conditions, but it requires an ActiveX control, and will not work in 99.99% of circumstances.
You can't use it to restore the file to the original location anyway (as you have absolutely no control over where downloads are stored, or even if they are stored) so in practice it is not a lot of use to you anyway.

Did you mean this?
$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
$("img").fadeIn("fast").attr('src',tmppath);
});

You can use the following code to get a working local URL for the uploaded file:
<script type="text/javascript">
var path = (window.URL || window.webkitURL).createObjectURL(file);
console.log('path', path);
</script>

One interesting note: although this isn't available in on the web, if you're using JS in Electron then you can do this.
Using the standard HTML5 file input, you'll receive an extra path property on selected files, containing the real file path.
Full docs here: https://github.com/electron/electron/blob/master/docs/api/file-object.md

You can, if uploading an entire folder is an option for you
<input type="file" webkitdirectory directory multiple/>
change event will contain:
.target.files[...].webkitRelativePath: "FOLDER/FILE.ext"
but it doesn't contain the whole absolute path, only the relative one. Supported in Firefox also.

you should never do so... and I think trying it in latest browsers is useless(from what I know)... all latest browsers on the other hand, will not allow this...
some other links that you can go through, to find a workaround like getting the value serverside, but not in clientside(javascript)
Full path from file input using jQuery
How to get the file path from HTML input form in Firefox 3

One could use the FileReader API for changing the src of an img element.
https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsDataURL

This is a working solution for me
const path = (window.URL || window.webkitURL).createObjectURL(file);
It will return a blob URL to locally access the file.

file element has and array call files it contain all necessary stuff you need
var file = document.getElementById("upload");
file.addEventListener("change", function() {
for (var i = 0; i < file.files.length; i++) {
console.log(file.files[i].name);
}
}, false);

You can get the full path of the selected file to upload only by IE11 and MS Edge.
var fullPath = Request.Form.Files["myFile"].FileName;

$('input[type=file]').change(function () {
console.log(this.files[0].path);
});
This is the correct form.

<img> content: default value

I am new to HTML5 and javascript and I have a question.
I have the following HTML code
<img id='image_preview'/>";
<input type='file' name='fileUpl' id='fileUpl' onchange='doUpl();' accept='image/*'/>
So in short, there is a button, every time I click it, doUpl() is executed. It loads a picture and shows a preview of the picture into <img ... >
the js function is
function doUpl() {
var file = document.getElementById('fileUpl').files[0];
...
dataUrl = canvas.toDataURL("image/jpeg");
document.getElementById('image_preview').src = dataUrl;
...
I would like to have the input field pre-loaded with a default picture path (ex. c:\test.jpg) and the preview of test.jpg already shown when the page is loaded the first time. If the button is pressed the picture is updated.
At the moment, when I first load the html page there is no preview and the input path is empty.
Can anyone help me with this?
Thanks :)
edit: sorry for the confusion. the test img is of course on the server not on the client PC.

I would like to have the input field pre-loaded with a default picture path (ex. c:\test.jpg)
You can do that using the value attribute. Something like this:
<input type='file' name='fileUpl' id='fileUpl' onchange='doUpl();' accept='image/*' value='c:\test.jpg'/>
the preview of test.jpg already shown when the page is loaded the first time.
There are a couple ways you can do this. The basic one is to do like above, using the src attribute:
<img id='image_preview' src='c:\test.jpg'/>"
But, I think is better to do using javascript, because, if one day you need to change this standard image, you only change it on the input element.
</body>
<script>
// self executing function here
(function() {
doUpl(); //this will execute when page is loaded.
})();
</script>
P.S. This is only possible if you have c:\test.jpg on your server

You can check if there is something on the input and fake the img and fake the path but you cannot get a real image from the user hard drive because it's security

If you are talking about preloading images from the client's filesystem, I'm afraid this is not possible due to obvious security reasons:
The specification of the File API states that:
(..) This specification also assumes that the primary user interaction is
with the element of HTML forms [HTML], and that
all files that are being read by FileReader objects have first been
selected by the user (..)

Changing embed src attribute dynamically using file dialog

I implemented a HTML page which runs locally on a Linux machine (using the most current firefox versions). It is used to embed a plugin which I have programmed.
At the moment, I statically pass a file path, the plugin has to load, that is hard-coded in the HTML file:
<embed id="embed1" type="application/x-bbx" src="/tmp/testfile.bbx"></embed>
The HTML page is generated for all .bbx files. I'm currently trying to figure out how I can avoid the hard-coded path by adding an <input type="file"> element. The aim is to dynamically change the loaded file (specified by src) to avoid the need of generating the HTML page for all .bbx files.
As browsers do not allow access to the file path: how I can change the embed's source according to the loaded file?
For several technical reasons, I would like to avoid using JQuery. Also note, that the page is run solely locally by specific users.
EDIT 1: The plugin is scriptable, i.e. I can invoke functions on and pass parameters to the plugin using JavaScript. Thus, it would suffice to get the whole file path and pass it to the plugin which in turn does the rest internally.
EDIT 2: For clarification: I want to avoid the burden of having the user enter the file path manually, which is why I intended to use <input type="file">

var Target = "/tmp/testfile2.bbx";
var Source = document.getElementById('embed1');
var Clone = Source.cloneNode(true);
Clone.setAttribute('src',Target);
Source.parentNode.replaceChild(Clone,Source);
But history of browser gets no event here... so .back() will work incorrectly.
Thats how I got here today. Hope this helps. And sorry if a was not fluxed to the right moment. ;-)

If I understood right, this should do it!
<script>
var embed1 = document.getElementById('embed1');
embed1.src = 'your path';
</script>

Here is a complete example:
JSFiddle
<input type="text" id="path" name="path" />
<input type="submit" id="submit" value="Change it" onclick="changePath()">
<embed id="embed1" type="application/x-bbx" src="/tmp/testfile.bbx"></embed>
<script>
function changePath() {
var e = document.getElementById('path');
var val = e.value;
var embed1 = document.getElementById('embed1');
embed1.src = val;
}
</script>

How to get input file 's data in old version browser

I use <input type="file"/> to upload files and want to get file's message when I choose a file.
I can read it in console use:
console.log($("input[type=file]"));
but I don't know how to get .files here:
for example,I want to get file size:95786 ,how to get it using JQuery?
update：
this.files[0].size dosen't work in IE7,I want more compatible function.

Simple, you can use the querySelector() method to access the DOM elements.
This is how you should do it -
var files = document.querySelector("input[type=file]").files;
console.log(files);

<input type="file" id="myFile" />
try the following:
//binds to onchange event of your input field
$('#myFile').bind('change', function() {
//this.files[0].size gets the size of your file.
console.log(this.files[0].size);
});
Old browsers support
Be aware that old browsers will return a null value for the previous this.files call, so accessing this.files[0] will raise an exception and you should check for File API support before using it

You can get the file size using
$('input[type=file]').bind('change', function() {
console.log(this.files[0].size);
});

I always recommend checking out the jQuery File Upload plugin. It enables easy access to loads of information about uploads, including live upload speeds, bytes uploaded so far, and total upload size.
