Copying file names from upload to textarea
I have a code that will copy the file names and add them to the textarea. Everything works but when you add more files, the first ones are deleted. How to fix it?
updateList = function() {
var input = document.getElementById('file');
var output = document.getElementById('fileList');
output.innerHTML = '';
for (var i = 0; i < input.files.length; ++i) {
output.innerHTML += 'n' + input.files.item(i).name + '';
}
output.innerHTML += ' n';
}<!DOCTYPE html>
<html lang="en" >

<meta charset="UTF-8">
<title>Display file name in page after selecting file in file input</title>
</head>
<form>
<input type="file" name="file" id="file" multiple

Why would the first ones be deleted if you loop over all the files?

You are setting your textarea value to empty string.
You can fix by removing the line:
output.innerHTML = '';

When you add more files the function will run again and updste your filelist. but in your code you reset the list of files here:
output.innerHTML = '';
so instead you want to have whats currently in there. replace it with that:
updateList = function() {
var input = document.getElementById('file');
var output = document.getElementById('fileList');
output.innerHTML = output.value;
for (var i = 0; i < input.files.length; ++i) {
output.innerHTML += 'n' + input.files.item(i).name + '';
}
output.innerHTML += ' n';

When you add more files the function will run again and updste your filelist. but in your code you reset the list of files here:
output.innerHTML = '';
so instead you want to have whats currently in there. replace it with that:
updateList = function() {
var input = document.getElementById('file');
var output = document.getElementById('fileList');
output.innerHTML = output.value;
for (var i = 0; i < input.files.length; ++i) {
output.innerHTML += 'n' + input.files.item(i).name + '';

output.innerHTML += ' n';
