How To Create .txt File Using Javascript / Html5?

I am new to javascript . all codes available on the internet related to create text file using javascript is not working in my laptop. can anybody give me idea or with possible cod

Solution 1:

This code should work, give this a try and if this doesn't work then it may be an issue with your browser:

(function () {
var textFile = null,
  makeTextFile = function (text) {
    var data = newBlob([text], {type: 'text/plain'});

    // If we are replacing a previously generated file we need to// manually revoke the object URL to avoid memory leaks.if (textFile !== null) {
      window.URL.revokeObjectURL(textFile);
    }

    textFile = window.URL.createObjectURL(data);

    return textFile;
  };


  var create = document.getElementById('create'),
    textbox = document.getElementById('textbox');

  create.addEventListener('click', function () {
    var link = document.getElementById('downloadlink');
    link.href = makeTextFile(textbox.value);
    link.style.display = 'block';
  }, false);
})();

And the HTML:

<textarea id="textbox">Type something here</textarea> <button id="create">Create file</button> 
<a download="info.txt"id="downloadlink" style="display: none">Download</a>

Solution 2:

A very fast and easy solution is to use FileSaver.js : https://raw.githubusercontent.com/eligrey/FileSaver.js/master/FileSaver.js

Then it takes only 2 lines of code to download a txt file :

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});

saveAs(blob, "hello world.txt");

This code example will display a dialog box to download a file named "hello world.txt" containing the text "Hello, world!". Just replace this by the file name and the text content of your choice !
