Single button for uploading-submitting file - autosubmit file on change. JQuery

I want the upload button (that will be hidden) to automatically work out as soon as file is selected(on change). The problem is that I get following error messege. I searched for it and there was an advice to change the name of the button but it didnt help. Here is the error: videator.php:380 Uncaught TypeError: document.getElementById(...).submit is not a function


document.getElementById("fileToUpload").onchange = submitAction;

function submitAction()
return false;


<form action="videator.php" method="post" enctype="multipart/form-data" id='btnSubmit'>
<h3> Select a video to upload:</h3>
<img class='upload' src="img/upload.png"/>
<input class="form" type="file" name="fileToUpload" id="fileToUpload" accept="video/*" >
<input class="form" id='' type="submit" value="Upload Image" name="submit">

What am I doing wrong? So again: I need a sigke button instead of 2 buttons (default) . So you click on it and upload-file window pops up - you select a file and it gets uploaded automatically.Help, please.

Following what was said here:

"Submit is not a function" error in JavaScript

You have a submit input named "submit".

<input class="form" id='' type="submit"  value="Upload Image"  name="submit">

This is what's causing the error to be thrown. If you rename that button to anything else it should work.

<input class="form" id='' type="submit"  value="Upload Image"  name="newName">

Here's a working example. If you open up the console you'll see your submit error is gone.
