我可以干掉这些jQuery调用吗？

Question

有没有办法干掉这个jQuery？

<script type="text/javascript">
  $('form input#search').watermark('search...');
</script>
<script type="text/javascript">
  $('form input#post_title').watermark('title');
</script>
<script type="text/javascript">
  $('form input#post_tag_list').watermark('tag (separate tags with a comma)');
</script>
<script type="text/javascript">
  $('form input#post_name').watermark('name (optional)');
</script>
<script type="text/javascript">
  $('form input#post_email').watermark('email (optional)');
</script>
<script type="text/javascript">
  $('form textarea#post_content').watermark('message');
</script>
<script type="text/javascript">
  $('form input#comment_commenter').watermark('name (optional)');
</script>
<script type="text/javascript">
  $('form input#comment_email').watermark('email (optional)');
</script>
<script type="text/javascript">
  $('form textarea#comment_body').watermark('reply');
</script>
<script type="text/javascript">
  jQuery(document).ready(function() {
    jQuery("abbr.timeago").timeago();
  });
</script>

它看起来非常重复.

编辑:我在所有表单中添加了占位符元素.我的应用程序是HTML5,所以没关系.我用过这段代码:

<script type="text/javascript">
  jQuery(function(){
    jQuery("abbr.timeago").timeago();
    jQuery('form input, form textarea').each(
      function(){
        jThis = jQuery(this);
        jThis.watermark(jThis.attr('placeholder'));
      }
    }
  );
</script>

Chrome使用或不使用JS渲染占位符,而FF 3.6.8和Opera 10.61显示空输入/ textarea框.我应该使用$而不是jQuery(function(){...？或者重要吗？

注意:我正在使用jQuery 1.4.2

如果你在标题属性中存储了水印函数的参数,那么你可以有这样的东西;

<form>
    <input type="text" id="search" title="search..." />
    <input type="text" id="post_title" title="title" />
    <input type="text" id="post_tag_list" title="tag (separate tags with a comma)" />
    <input type="text" id="post_name" title="name (optional)" />
    <input type="text" id="post_email" title="email (optional)" />
    <input type="text" id="post_content" title="message" />
    <input type="text" id="comment_commenter" title="name (optional)" />
    <input type="text" id="comment_email" title="email (optional)" />
    <input type="text" id="comment_body" title="reply" />
</form>

<script type="text/javascript">
    jQuery(function(){
        jQuery("abbr.timeago").timeago();
        jQuery('form input, form textarea').each(
            function(){
                jThis = jQuery(this);
                jThis.watermark(jThis.attr('title'));
            }
        }
    );
</script>
