Get JSON from local JavaScript

Question

good afternoon. I'm developing an app that can get a JSON from local (manifest.json). I want to get this file from JavaScript and then read it. But I have a problem, I cant call this file. How can I?

var urlJSON = new XMLHttpRequest("manifes.json").toString;
var dataJSON = JSON.parse(urlJSON);

alert(dataJSON.name);

Answer 1

var xmlhttp = new XMLHttpRequest();
var url = 'manifest.json';
xmlhttp.onreadystatechange = function() {
  if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
    console.log(JSON.parse(xmlhttp.responseText));
  }
  if (xmlhttp.status == 404) {}
};
xmlhttp.open('GET', url, true);
xmlhttp.send();

Or run chrome with arguments --allow-file-access-from-files
Or download and create server for your app
