Practically nobody would use document.write to update any dom element. Please don't use document.write in your web update. You can update input by document.getElementById("demo").value = "hello world");

In the if section you can write, if(value.length<=6){ value.innerHTML="hello world" } this will assign the element with id demo "hello value" or you can do what Calvin says
