代码在 jsfiddle 中工作但不在 jsfiddle 结果中

Question

这是我的 jsFiddle HTML:

<script 
src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">
</script>
<table id="tableone" border="2" cellspacing="2" cellpadding="2">
<thead>
<tr>
<th class="col1">Seminar Name</th>
<th class="col2">Seminar Date</th>
<th class="col3">Download Link</th>
<tbody>
<tr class="del">
<td contenteditable="false"></td>
<td contenteditable="false"></td>
<td contenteditable="false"></td>
<td>
<button class="editbtn">Edit</button>
</td>
</tr>
<tr class="del" id="tablerow">
<td contenteditable="false"></td>
<td contenteditable="false"></td>
<td contenteditable="false"></td>
<td>
<button class="editbtn">Edit</button>
</td>
</tr>
</tbody>
<button class="addnewrow">Add New Row</button>

Javascript:

$('#tableone').on('click', '.editbtn', function() {
var $this = $(this);
var tds = $this.closest('tr').find('td').filter(function() {
return $(this).find('.editbtn').length === 0;  
});
if ($this.html() === 'Edit') {
$this.html('Save');
tds.prop('contenteditable', true);
} else {
$this.html('Edit');
tds.prop('contenteditable', false);
}
});
$('.addnewrow').click(function() {
var $tr = $("#tableone").find("tr:last");
var $clone = $tr.clone();
$clone.find('input').val('');
$tr.after($clone);
});

代码在 jfiddle 中工作正常但是当我去 https://jsfiddle.net/yT92K/42/show/result "add new row" 函数已停止工作。此外，当我尝试将文件导出为单独的 .html 文件时，它只会在我的浏览器中打开一个空白页面 (chrome)。有人对此有解决办法吗？

$('#tableone').on('click', '.editbtn', function() {
var $this = $(this);
var tds = $this.closest('tr').find('td').filter(function() {
return $(this).find('.editbtn').length === 0;
});
if ($this.html() === 'Edit') {
$this.html('Save');
tds.prop('contenteditable', true);
} else {
$this.html('Edit');
tds.prop('contenteditable', false);
}
});
$('.addnewrow').click(function() {
var $tr = $("#tableone").find("tr:last");
var $clone = $tr.clone();
$clone.find('input').val('');
$tr.after($clone);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

  <td contenteditable="false"></td>
  <td contenteditable="false"></td>
  <td>
  <button class="editbtn">Edit</button>
  </td>
  </tr>
  <tr class="del" id="tablerow">

  <td contenteditable="false"></td>
  <td contenteditable="false"></td>
  <td>
  <button class="editbtn">Edit</button>
  </td>
  </tr>
  </tbody>
  <button class="addnewrow">Add New Row</button>

$( document ).ready(function() {
        $('#tableone').on('click', '.editbtn', function() {
            var $this = $(this);
            var tds = $this.closest('tr').find('td').filter(function() {
                return $(this).find('.editbtn').length === 0;
            });
            if ($this.html() === 'Edit') {
                $this.html('Save');
                tds.prop('contenteditable', true);
            } else {
                $this.html('Edit');
                tds.prop('contenteditable', false);
            }
        });
        $('.addnewrow').click(function() {
            var $tr = $("#tableone").find("tr:last");
            var $clone = $tr.clone();
            $clone.find('input').val('');
            $clone.find('td:not(:last)').empty();
            $clone.find('td:not(:last)').prop('contenteditable', false);
            $clone.find('button').html('Edit');
            $tr.after($clone);
        });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

试试这个！

这是对@zhuravlyoy 答案的补充，因为如果编辑了前一个答案，他的答案不会使新行空白。

$( document ).ready(function() {
        $('#tableone').on('click', '.editbtn', function() {
            var $this = $(this);
            var tds = $this.closest('tr').find('td').filter(function() {
                return $(this).find('.editbtn').length === 0;
            });
            if ($this.html() === 'Edit') {
                $this.html('Save');
                tds.prop('contenteditable', true);
            } else {
                $this.html('Edit');
                tds.prop('contenteditable', false);
            }
        });
        $('.addnewrow').click(function() {
            var $tr = $("#tableone").find("tr:last");
            var $clone = $tr.clone();
            $clone.children('.td').empty();
            $clone.children('.td').attr('contenteditable', false);
            $clone.find('.editbtn').text('Edit');
            $tr.after($clone);
