javascript - Show dynamically created divs one by one -


i trying show dynamically created li's 1 one. here code. idea why not work?

$('form').submit(function(e) {    e.preventdefault();    var userinput = $('#inputnumber').val();    console.log(outputresult);    var modifiedresult = outputresult.map(function(item) {      return '<li class="ball">' + item + '</li>'    });    $('.output').html(modifiedresult.join(""));    $('.ball').each(function(i, e) {      $(this).delay(i * 400).fadein();    });  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <ul class="output"></ul>

when $('.output').html(modifiedresult.join("")); lis visible (display property block default).

it suffice add style="display:none" in html strings create #map() function - see demo below:

var userinput = $('#inputnumber').val();  var outputresult = [1,2,3,4,5];  var modifiedresult = outputresult.map(function(item) {    return '<li style="display:none" class="ball">' + item + '</li>'  });  $('.output').html(modifiedresult.join(""));  $('.ball').each(function(i, e) {    $(this).delay(i * 400).fadein();  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <ul class="output"></ul>
