JavaScript Open Dialog to get path and file name

Okay,
I've looked EVERYWHERE and everyone keeps answering this question like we're going to actually "download" a file actively.
I am not downloading a file. I am not Uploading a file. I just want a dialog that allows the user to easily provide the path and filename for entry into a textbox so they don't have to type the whole damn thing manually.
don't ask why, or what I'm using it for, I just want to know how to open a simple filesystem dialog. The user browses, types a file name, clicks save, and the text input on the form is populated with the fully qualified path.
This is definitely possible (maybe not with javascript, but I've seen countless pages that open up a file browse dialog) so how do I do this?
Thanks

Not too long ago browsers disabled showing the full path to the file on your local machine due to security reasons.
Otherwise you could write ajax script to submit client's paths to the server without the person knowing.
Check the sample script:
$('#fileSelector').on('change', function( e ) {
$('#value').text( e.target.value );
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="fileSelector" type="file" />
<div id="value"></div>

You can do this with jQuery:
$(":file").change(function(){
alert($(":file").val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type="file">
</form>

When a file is uploaded to a website, can the website see the file path it's uploaded from?

When uploading a file, before pressing the upload button, the folder/file path is visible in the website's upload form.
.
Is the website able to record that data?
Normally a website could possibly record any data typed into a web form - is this any different?

It doesn't appear to work. I created the following fiddle https://jsfiddle.net/5samkn5a/
Basically I took an input
<input type="file" id="input"/>
And set a listener to its value
$(function(){
$("#input").change(function(){
console.log($(this).val());
})
})
Then I tried it in the latest chrome/firefox/edge
They all give a fake path as value. The only thing that's real is the file name. May be that some browsers actually expose the full path, but not the ones I tested.
It makes sense that the browser is shielding this information since at least on windows when you are choosing a document it will most likely reside in your current user directory. So the path will contain your local user name and that's not something you want to give to a random website, right?

How to post a file to a form using javascript automatically

I have some client-side JavaScript which will output a jpeg file based on HTML5 canvas manipulation, if the user performs an action such as clicking the "OK" button.
I would like the jpeg output to be automatically loaded into the "Upload Front Side" field in a form, as if the user uploaded the file from his or her own hard drive.
However, I can't seem to get it to work.
Here is the form:
<div class="property-wrapper">
<label for="upload-front">Upload Front Side</label>
<input id="upload" class="file" type="file" enctype="multipart/form-data" id="Front-Side" name="properties[Front Side]" onchange="readURL(this);" accept="image/*" />
</div>
<script>
document.getElementById('upload').value="http://upload.wikimedia.org/wikipedia/commons/thumb/2/22/Turkish_Van_Cat.jpg/353px-Turkish_Van_Cat.jpg"
</script>

The problem is browsers have several restrictions on what can be done programatically with file upload due to security reasons, have a look at this answer.
The file upload functionality is potentially exploitable, and some browsers will for example not open the explorer box if for example the file upload input field is hidden with display:none.
Most browsers will not allow programatic clicks to a file upload element and require the user to click them instead, to prevent attacks where someone sends a link to a page that immediately steals content from the user's hard drive.
So the functionality you mention does not seem to be feasible due to common browser security restrictions. There are usually no error messages or warnings, it just doesn't work.
An alternative to using the file upload browser input component could be to encode the contents of the file in Base64 and send in the body of an ajax POST for example.

Are you asking how to upload to a server, via a form, the graphic image you extracted from the canvas of your page? This would be useful, I hope to see this answered.
I would start by enabling the user to download/export the image. This might be done with a blob. Ive done this for text data exports, works nicely.
Maybe there is a way to apply the same tricks, just feed the blob/buffer to the server.
Another path might be to "PUT" the file at the server.
Hope this helps.

I would ajax POST a base64 encoded string of the image and forget the whole file upload thingy. You can upload the canvas code directly and reconvert it server side if you need a preview or something or see what other outputs are available from your canvas/image converter code.
I am assuming you are uploading to same server so you would not have cross domain issue but otherwise you can setup your server to accept cross domain ajax request very easily.

Getting full file path of a clients file using a file dialog box

I am trying to allow users to upload pictures to the server.
I am trying to create a similar system to any website that has an 'attach' file or 'upload image' feature. All I need is to get the full path of the file select by the file dialog.
I tried using this for the file dialog with no success:
<input type="file">
This method does not provide the full file path, due to security reasons. My question is how can I create a similar input dialog to websites like tinypic, photobucket, etc.. that can help users input the full file path of a given image, into an input field?
I am aware that this cannot be done using the method above for security reasons, however, I have seen this done before on various websites without any problems, I was wondering what I had to do to implement a similar file dialog that helps fill in the text, which is a full file path, of an input field?

It is not possible to get the file full path on local machine using browser and javascript.
However, as you would like to upload the file to the server, the easy possibility I see is to use html form with input type file. You will receive the file on your http server when the form is submitted.
Here is a very good url http://www.cs.tut.fi/~jkorpela/forms/file.html that explains the whole process nicely.

How to browse and display the image in the same page?

I've a very small doubt. I've a html tag to browse the file. and as soon as I browse the file from the local server, I want to set that path to the source of image tag. Is it possible to implement?
I've code something like this.
<form name="image" id="image" enctype="multipart/form-data" action="" method="post">
<input type="file" name="img" />
<img src=""></img>
</file>
So as soon as I browse and select the file from the local server,that path should be set to image tag.My intention is to browse the image and display it in that page itself. Any help will be appreciated. Thanks in advance.

Browsers have now allowed you to access the path of a file from the input[type=file] tag for a long time. You can't simply do it like you're trying to. In order to accomplish your goal of showing the file after the user selects it, you actually need to upload it to your server. This typically requires a page-refresh, but there are plenty of javascript libraries that are available in order to make it happen without refreshing the page. Once the file is uploaded, you can "ping back" a URL to view the image, and load that in your image tag.
The jQuery library I've been using recently to do inline file uploads is jQuery File Upload

What you need is the full path to the file on the client side - which is not allowed (see also this thread).
Sorry mate, but without sending the file to the server you can't do anything with it other than getting the file name (not the path), the file type and the file size.
