javascript - Can't set innerHTML on tbody in IE

Question

I have a table like this:

<table>
<thead>
    <tr>
        <th colspan="1">a</th>
        <th colspan="3">b</th>
    </tr>
</thead>
<tbody id="replaceMe">
    <tr>
        <td>data 1</td>
        <td>data 2</td>
        <td>data 3</td>
        <td>data 4</td>
    </tr>
</tbody>
</table>

and a method returns me the following after an ajax request:

<tr>
    <td>data 1 new</td>
    <td>data 2 new</td>
    <td>data 3 new</td>
    <td>data 4 new</td>
</tr>

I want to change the innerHTML like

document.getElementById('replaceMe').innerHTML = data.responseText;

However, it seems that IE can't set innerHTML on <tbody>. Can anyone help me with a simple workaround for this issue?

Answer 1

That is true, innerHTML on tbody elements is readOnly in IE

The property is read/write for all objects except the following, for which it is read-only: COL, COLGROUP, FRAMESET, HEAD, HTML, STYLE, TABLE, TBODY, TFOOT, THEAD, TITLE, TR.

You can do something like this to work around it:

function setTBodyInnerHTML(tbody, html) {
  var temp = tbody.ownerDocument.createElement('div');
  temp.innerHTML = '<table>' + html + '</table>';

  tbody.parentNode.replaceChild(temp.firstChild.firstChild, tbody);
}

Basically it creates a temporary node into which you inject a full table. Then it replaces the tbody with the tbody from the injected table. If it proves to be slow, you could make it faster by caching temp instead of creating it each time.
