Can I save input from form to .txt in HTML, using JAVASCRIPT/jQuery, and then use it?

It’s possible to save only if the user allow it to be saved just like a download and he must open it manually, the only issue is to suggest a name, my sample code will suggest a name only for Google Chome and only if you use a link instead of button because of the download attribute.

You will only need a base64 encode library and JQuery to easy things.

// This will generate the text file content based on the form data
function buildData(){
  var txtData = "Name: "+$("#nameField").val()+
      "\r\nLast Name: "+$("#lastNameField").val()+
      "\r\nGender: "+($("#genderMale").is(":checked")?"Male":"Female");

  return txtData;
}
// This will be executed when the document is ready
$(function(){
  // This will act when the submit BUTTON is clicked
  $("#formToSave").submit(function(event){
    event.preventDefault();
    var txtData = buildData();
    window.location.href="https://stackoverflow.com/questions/13685263/data:application/octet-stream;base64,"+Base64.encode(txtData);
  });

  // This will act when the submit LINK is clicked
  $("#submitLink").click(function(event){
    var txtData = buildData();
    $(this).attr('download','sugguestedName.txt')
      .attr('href',"https://stackoverflow.com/questions/13685263/data:application/octet-stream;base64,"+Base64.encode(txtData));
  });
});
