javascript - How do I create button that returns to "hidden" data onclick in js, that was previously input by user? -


how create button returns "hidden" data onclick in js, input user?

<html>  <script>    var input,      inputcount = 0;    function newinput () {    if (input !== undefined) {      input.type = "hidden";      }    inputcount++;        input = document.createelement("input");    input.type = "text";    input.name = input.placeholder = "fname" + inputcount;    document.getelementbyid("box").appendchild(input);  }  </script>  <button type="button" onclick="newinput()">add property</button><br/>  <form action="#" method="post">    <br/><span id="box"></span><br/><br/>    <input type="submit" value="submit">  </form>  </html>

i suggest use jquery in programs. it'll make life easier 

<button type="button" class="hiding-button">add property</button>  <script src="//code.jquery.com/jquery-1.11.3.min.js"></script> <script src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script> <script>     $(".hiding-button").on("click",function(){         newinput();         $(this).hide();     }); </script>
