Yes it is, you could do something like this in HTML5, using the download attribute

function download_txt() {

  var textToSave = document.getElementById('txt').innerHTML;

  var hiddenElement = document.createElement('a');



  hiddenElement.href = 'data:attachment/text,' + encodeURI(textToSave);

  hiddenElement.target = '_blank';

  hiddenElement.download = 'myFile.txt';

  hiddenElement.click();

}



document.getElementById('test').addEventListener('click', download_txt);

FIDDLE
