我有一个 Drupal 站点，我需要限制评论长度。所以，我找到了这段代码：

在 ghead 里面我应该添加这个：

<script language=”javascript”&gt;
function limit(what,chars,counter) {
if (what.value.length > chars) {
what.value=what.value.substr(0,chars);
alert(‘You exceed to ‘ + chars + ‘chars!’);
}
counting = (chars – what.value.length);
c = document.getElementById(counter);
c.innerHTML = counting;
}
</script>

我应该在我放置评论正文的地方添加这些东西：

<p><label for=”text”&gt;<strong>Text</strong></label> ¦ Chars left: <span id=”count1″&gt;500</span></p>
<textarea name=”[1][2][t]” rows=”10″ cols=”50″ onkeyup=”limit(this,500,’count1′);” onkeydown=”limit(this,500,’count1′);” onblur=”limit(this,500,’count1′);” onfocus=”limit(this,500,’count1′);”&gt;</textarea>

我的问题是我不知道该把它放在哪里。我认为这在 template.tpl.php 文件中。

我找到了一个自定义示例，但不知道如何插入上面的代码：

/**
* Theme the output of the comment_form.
*
* @param $form
*   The form that  is to be themed.
*/
function mytheme_comment_form($form) {

  // Rename some of the form element labels.
  $form['name']['#title'] = t('Name');
  $form['homepage']['#title'] = t('Website');
  $form['comment_filter']['comment']['#title']  = t('Your message');

  // Add some help text to the homepage field.
  $form['homepage']['#description'] = t('If you have your own website, enter its address here and we will link to it for you. (please include http://).');
  $form['homepage']['#description'] .= '<br/>'. t('eg. http://www.kirkdesigns.co.uk');

  // Remove the preview button
   $form['preview'] = NULL;

  return drupal_render($form);
}

希望任何人都可以在这里帮助我，因为我几乎一无所知。

谢谢！

将您的 javascript 代码放到 comment.tpl.php 或其他模板文件中。并在 mytheme_comment_form($form) 函数中将属性添加到您的文本区域：

$form['textareaname']['#attributes'] = array('onkeyup' => 'limit(this,500,’count1′)';
$form['textareaname']['#title'] = "<label for=”text”&gt;<strong>Text</strong></label> ¦ Chars left: <span id=”count1″&gt;500</span>"
