title: on second click remove text from button click
body: <p>How can I remove the text "Input this text in textarea on click" when I click the "Input text button" for the second time? Is it possible without javascript?</p>
  
  <pre><code>&lt;textarea name=\"text\" rows=\"10\" cols=\"50\"&gt;" . htmlspecialchars($arr["text"]) . "&lt;/textarea&gt;
  
  
  
  &lt;INPUT TYPE="button" NAME="insert" VALUE="Input text button" onClick="this.form.text.value=this.form.text.value.concat('Input this text in textarea on click');"&gt;
  </code></pre>
