Question

How could I hide the ‘Edit’-link after I press it? and also can I hide the “lorem ipsum” text when I press edit?

<script type="text/javascript">
function showStuff(id) {
  document.getElementById(id).style.display = 'block';
}
</script>


<td class="post">

  <a href="#" onclick="showStuff('answer1'); return false;">Edit</a>
  <span id="answer1" style="display: none;">
    <textarea rows="10" cols="115"></textarea>
  </span>

  Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum 
</td>

Answer 1

function showStuff(id, text, btn) {
    document.getElementById(id).style.display = 'block';
    // hide the lorem ipsum text
    document.getElementById(text).style.display = 'none';
    // hide the link
    btn.style.display = 'none';
}

<td class="post">

<a href="#" onclick="showStuff('answer1', 'text1', this); return false;">Edit</a>
<span id="answer1" style="display: none;">
<textarea rows="10" cols="115"></textarea>
</span>

<span id="text1">Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum</span>
</td>
