I have a file input like this in html
<input type='file' id='textin'></input>
How Do I Get The Contents Of The .txt File Uploaded?
You can do this via FileReader.
function previewFile() {
const content = document.querySelector('.content');
const [file] = document.querySelector('input[type=file]').files;
const reader = new FileReader();
reader.addEventListener("load", () => {
// this will then display a text file
content.innerText = reader.result;
}, false);
if (file) {
reader.readAsText(file);
}
}<input type="file" onchange="previewFile()" id="textin"><br>
<p class="content"></p>
