JavaScript File API, Blobs and FileReaders Read file as string
Example
Make sure to have a file input on your page:
<input type="file" id="upload">
Then in JavaScript:
document.getElementById('upload').addEventListener('change', readFileAsString)
function readFileAsString() {
var files = this.files;
if (files.length === 0) {
console.log('No file is selected');
return;
}
var reader = new FileReader();
reader.onload = function(event) {
console.log('File content:', event.target.result);
};
reader.readAsText(files[0]);
}
