any appreciated.

you trying handle identifier using class name inside getelemlementbyid

you should able remove container of clcked x, similar this: $(this).closest('.hiddenimages').remove();

in addition selector click event on x might need change removing container binding , such new .hiddenimages container not have click event bound.

you might need update $('.hiddenimages .close').on('click', function... $('.pictureholders').on('click', '.hiddenimages .close', function...

$(document).ready(function() {    // create thumbnail:    $('#uploadimage').on('change', function() {      resizeimages(this.files[0], function(dataurl) {        $('#photo1').val(dataurl);        document.getelementbyid("uploadpreview").src = dataurl;      });    });      // attempting delete it:    $('.pictureholders').on('click', '.hiddenimages .close', function() {      $(this).closest('.hiddenimages').remove();    });  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div class="pictureholders">    <div class="hiddenimages">      <span class="close">&times;</span>      <img id="uploadpreview" data-id="photo-1" style="width: 100px;       height: 100px;" />    </div>    <div class="hiddenimages">      <span class="close">&times;</span>      <img id="uploadpreview2" data-id="photo-2" style="width: 100px;         height: 100px;" />    </div>    <div class="hiddenimages">      <span class="close">&times;</span>      <img id="uploadpreview3" data-id="photo-3" style="width:         100px; height: 100px;" />    </div>    <div class="hiddenimages">      <span class="close">&times;</span>      <img id="uploadpreview4" data-id="photo-4" style="width: 100px;          height: 100px;" />    </div>  </div>  <div class="inputs">    <div> photo 1:      <input type="text" id="desc1" name="desc1" />      <input id="uploadimage" type="file" />    </div>    <input type="hidden" class="photos" id="photo1" name="photo1" value="" />    <br/>    <div> photo 2:      <input type="text" id="desc2" name="desc2" />      <input id="uploadimage2" type="file" />    </div>    <input type="hidden" class="photos" id="photo2" name="photo2" value="" />    <br/>    <div> photo 3:      <input type="text" id="desc3" name="desc3" />      <input id="uploadimage3" type="file" />    </div>    <input type="hidden" class="photos" id="photo3" name="photo3" value="" />    <br/>    <div> photo 4:      <input type="text" id="desc4" name="desc4" />      <input id="uploadimage4" type="file" />    </div>    <input type="hidden" class="photos" id="photo4" name="photo4" value="" />      <br/>  </div>
