   1:  (function($) {

   2:      $.fn.clearAll = function(c) {

   3:          var $this = $(this);

   4:          var v = $('input,textarea,select', $this);

   5:          if (c) v = v.filter('[disabled!="true"][readonly!="readonly"]:not(.textbox_disabled)');

6:

   7:          v.filter(function() { return this.type.match(/(text|password)/); }).val('');

   8:          v.filter(':checked').attr('checked', false);

   9:          v.filter('select').children('option:selected').removeAttr('selected');

  10:          v.filter('select').children(':first-child').attr('selected', true);

  11:      }

12:

  13:  })(jQuery);

用法:

   1:  // 刪除所有table裡所有文字方塊,下拉選單, checkbox, radiobutton 的資料內容

   2:  $('table').clearAll();

3:

   4:  // 刪除所有table裡除唯讀外之文字方塊,下拉選單, checkbox, radiobutton 的資料內容.

   5:  $('table').clearAll(true);

註: textbox_disabled 是自訂的 css 名稱

如:

<input type="text" class="textbox_disabled" value="123" />
