我有以下HTML，我希望添加类HideEdit以使用CSS隐藏列。
<th class="rgHeader" style="text-align: left;" scope="col" _events="[object Object]" control="[object Object]" UniqueName="Edit">
上面的HTML是使用radGrid生成的。我打算在打印期间隐藏页面上的所有编辑列。我为@mediaPrint配置了我的CSS。我无法使用rgHeader，因为此类已被radGrid中的所有列使用。
为了达到预期的效果，我必须将HideEdit类添加到<th>所有UniqueName="Edit"个标记中。
我尝试过以下内容：
$("th.rgHeader:contains('UniqueName=\"Edit\"')").addClass('HideEdit');
以下是完整的HTML：

答案 0 :(得分：0)
.HideEdit{display:none;}
$('th.rgHeader').addClass('HideEdit');
您可以使用等效选择器在dom或元素中以数字方式查找元素。
$('th:eq(0)').addClass();//this would be the first within the DOM
$('th:eq(1)','table#element').addClass();//this would be the second table header within the table with an id of element.
要隐藏整个列，您必须为每列添加一个类或使用eq()
$('td:eq(5),td:eq(5)','table#element>tr').hide();//this will hide the 6th column within the table with the id element
jQuery选择器也可以赋予属性
$('element[attribute="value"]')
我认为这就是你的意思？
$('th[UniqueName="Edit"]')
$('td[UniqueName="Edit"]')
我喜欢在形式上使用这种方法来获得便利。
$('input[type="text"]').keyup();
反对
$('#username,#password,#other').keyup();
试试这个
$('td:eq(0),th:eq(0)','#ctl00_ctl22_g_6f2f4cde_9491_4d9a_b866_c338a5db0248_g_6f2f4cde_9491_4d9a_b866_c338a5db0248Grid_ctl00>tr').hide();
但可以采用不同的风格。试试这个，因为我有点困惑：p
$('tr:eq(0)','#ctl00_ctl22_g_6f2f4cde_9491_4d9a_b866_c338a5db0248_g_6f2f4cde_9491_4d9a_b866_c338a5db0248Grid_ctl00').hide();
第二个选择器会使第一行消失，其中所有＆＃39; UniqueName＆＃39;属性似乎是。第一个是第一个“第一列”。消失。
