How to read a local text file?

Question

I’m trying to write a simple text file reader by creating a function that takes in the file’s path and converts each line of text into a char array, but it’s not working.

Answer 1

var input = document.getElementById("myFile");
var output = document.getElementById("output");


input.addEventListener("change", function () {
  if (this.files && this.files[0]) {
    var myFile = this.files[0];
    var reader = new FileReader();
    
    reader.addEventListener('load', function (e) {
      output.textContent = e.target.result;
    });
    
    reader.readAsBinaryString(myFile);
  }   
});
