将CSS样式应用于包含错误消息的Div

问题描述 投票：0回答：2
**请参见示例

，我不希望在没有消息时应用样式。

代码： $( document ).ready(function() { if($('.CP_CF_Container > span.msg-error').length){ $('.vertical-input').addClass('checkbox-fld-error') } });

CSS：

.checkbox-fld-error{border:1px solid red} .CP_CF_Container{width:50%;background-color:#eee;padding:5px;} .msg-error{color:red} 

Html：

<div class="CP_CF_Container"> <div class="vertical-input">hello there</div> <span class="msg-error" >Error</span> </div> <br> <div class="CP_CF_Container"> <div class="vertical-input">hello there</div> <span class="msg-error" >Error</span> </div> <br> <div class="CP_CF_Container"> <div class="vertical-input">hello there</div> </div>

您可以链接方法并使用

.prev()
或
.siblings()
jquery

$('.CP_CF_Container > span.msg-error') .prev('.vertical-input') .addClass('checkbox-fld-error');

您还可以使用
.has()
返回/过滤具有指定元素的元素的方法：

$('.CP_CF_Container').has('span.msg-error')
                     .find('.vertical-input')
                     .addClass('checkbox-fld-error');


    


页面上的jQuery有点畸形：



改变：
if($(this).('.CP_CF_Container > span.msg-error').length){
