javascript - Scrolltop animation locking scroll -


i have form multiple fields. in each field, page scroll bottom

$('.my_input').on('change', function(e){     $("html, body").animate({ scrolltop: $("html, body").height()}, "slow"); }

this works fine, if try scroll top, page "freeze" scroll in bottom, releasing after several attemps.

how fix it?

tks

maybe event firing again , again. can try using one fire event once.

see code below. please share sufficient code replicate problem, if doesn't maybe reason problem.

$(document).ready(function(){  $('.my_input').one('change', function(e){      $("html, body").animate({ scrolltop: $("html, body").height()}, "slow");  });  });
.my_input{  display:block;  margin-bottom:300px;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>    <input type="text" class="my_input"/>  <input type="text" class="my_input"/>  <input type="text" class="my_input"/>
