How do i remove a dynamically created div?

Question

i have a the following code to load a treeview with data using jstree plugin and plugin was attached to index view of MVC4

<div id="jstree_demo_div">
    <ul>
        <li class="jstree-closed">Root node 1
            <ul>
                <li class="c1">child1</li>
                <li class="c1">child2</li>
            </ul>
        </li>
        <li class="jstree-closed">Root node 2
            <ul>
                 <li class="c1">child3</li>
                 <li class="c1">child4</li>

           </ul>
        </li>
  </ul> 
</div>

<div id="Divtxt1"></div>
<h2>Index</h2>
@section Scripts{
    <script src="Scripts/jstree.min.js"></script>
    <script> 
       $(document).ready(function () {//{ "theme": { "icons": true }
           $('#jstree_demo_div').jstree();

           $(document).on('click', '.c1', function () {
               var nodeText = $(this).text();
               //alert(nodeText);
               $('#Divtxt1').append('<div style="display:inline-block;border:1px solid black" ' + 'id=' + nodeText + '>' +
                   '<textarea style=width:100px;height:100px;visibility:visible;' + 'id=txta' + nodeText + '>' + nodeText +
                   ':</textarea>')
               .append('<input type="button" class="del" value="Del"' + 'id=' +'btn-' + nodeText + ' />')
               .append('</div><br />');
           });

           $(document).on('click', '.del', function () {
               var btnId = $(this).attr('id');
               var coll = btnId.split('-');
               alert(coll[1]);
               //alert( $(this).attr('id') )
               alert($(this).find('textarea[id=txta'+coll[1]+']').text());
               alert( $(this).closest('div').html() );
           });
        });
    </script>

    }

the above code will dynamically add divs with <textarea> and a button when the user clicks a child node of any parent. The purpose of the button is to delete its div( so it will remove the textarea and also button with it). But the problem i have is the button does not delete it.

another is the following code: alert($(this).find('textarea[id=txta'+coll[1]+']').text());

should display the text in the textarea but it does not either. So how do i remove the div the button is in?

Answer 1

There are 2 problems, first they way you have used append() is not proper, it doesn't work like string concatenation. Second you need to delete the parent div element

$(document).ready(function() { //{ "theme": { "icons": true }
  $('#jstree_demo_div').jstree();

  $(document).on('click', '.c1', function() {
    var nodeText = $(this).text();
    //alert(nodeText);
    var html = '<div style="display:inline-block;border:1px solid black" ' + 'id=' + nodeText + '>' + '<textarea style=width:100px;height:100px;visibility:visible;' + 'id=txta' + nodeText + '>' + nodeText + ':</textarea>' + '<input type="button" class="del" value="Del"' + 'id=' + 'btn-' + nodeText + ' /></div><br />';
    $('#Divtxt1').append(html);
  });

  $(document).on('click', '.del', function() {
    $(this).closest('div').remove();
  });
});

        <li class="c1">child2</li>
      </ul>
    </li>
    <li class="jstree-closed">Root node 2
      <ul>
        <li class="c1">child3</li>
        <li class="c1">child4</li>

      </ul>
    </li>
  </ul>
</div>

<div id="Divtxt1"></div>
<h2>Index</h2>

Answer 2

Try this :You can find the parent div using closest() and then call remove() method on it to remove the div and its child elements.

$(document).on('click', 'input.del', function () {
     var $parentDiv = $(this).closest('div');  
     $parentDiv.remove();   
});
