关于一些简单的jquery问题
<tr> <td width="2%"> </td> <td> input type="checkbox" name="role_auth_ids[]" class="menus" value="1"/><b><font color='red'>权限管理</b></font></td> <td> <div style="width:100px;float:left" id="d1"><input type="checkbox" name="role_auth_ids[]" class="submenus" value="2"/>添加权限</div> <div style="width:100px;float:left" id="d1"><input type="checkbox" name="role_auth_ids[]" class="submenus" value="3"/>权限列表</div> <div style="width:100px;float:left" id="d1"><input type="checkbox" name="role_auth_ids[]" class="submenus" value="7"/>权限分配</div> </td></tr>
我想问的是使用jquery怎么实现 在选中权限管理得情况下,取消选中 '添加权限' 和 '权限列表' 和 '权限分配' 时,权限管理也自动取消选中。 也就是取消选中最后面单元格的checkbox就自动取消选中 权限管理
回复讨论(解决方案)
建议去看看jquery的手册吧
juqery 全选和反选
$(function() { $('[name="role_auth_ids[]"]:eq(0)').click(function() { if($(this).prop('checked') == false) $('[name="role_auth_ids[]"]:gt(0)').prop('checked', false); }); $('[name="role_auth_ids[]"]:gt(0)').click(function() { var n = 0; $('[name="role_auth_ids[]"]:gt(0)').each(function() { if($(this).prop('checked')) n++; }); $('[name="role_auth_ids[]"]:eq(0)').prop('checked', n ? true : false); });})
楼上的方法不可以啊,不是全选和反选的意思~
我那是全选和反选吗?你试了没有?
去掉 “权限管理” 的勾选 '添加权限' 和 '权限列表' 和 '权限分配" 已选的变成不选
'添加权限' 和 '权限列表' 和 '权限分配" 任意选中几个,“权限管理”选中
'添加权限' 和 '权限列表' 和 '权限分配"都不选,“权限管理”不选
我就是想实现
'添加权限' 和 '权限列表' 和 '权限分配" 任意选中几个,“权限管理”选中
'添加权限' 和 '权限列表' 和 '权限分配"都不选,“权限管理”不选
但是实现不了啊
你那个prop是什么意思??
哦,可以实现了,以前用的jquery 不支持 prop方法 实现不了,换了就可以了~赞
