Answer 1

you can do this:

 function add_input(element) { var btn = document.createElement("input"); btn.setAttribute('type', "submit"); btn.setAttribute('value', "Submit"); element.appendChild(btn); }

 <ul> <li > <textarea >title</textarea> <a href="#" onclick=add_input(this)>tt</a> </li> </ul>

Answer 2

it is work for me ?==>event ???==> e.target.parentElement.appendChild(btn)

 function add_input(e) { var btn = document.createElement("input"); btn.setAttribute('type', "submit"); btn.setAttribute('value', "Submit"); e.target.parentElement.appendChild(btn) }

 <ul> <li > <textarea >title</textarea> <a href="#" onclick=add_input(event)>tt</a> </li> </ul>
