Question

这是类名为“ aid_wrap ”的示例div。

<div class="assistance_wrap">
<div class="top"></div>
<div class="header highlight">Types of assistance offered at this event:</div>
<div class="nearby_header highlight">This event is currently full, but there are other ways you can</div>
</div>

我克隆了这个div，每个克隆版本附加了一个唯一的ID。

<div id="assistance_wrap_315" class="assistance_wrap">
<div class="top"></div>
<div class="header highlight">Types of assistance offered at this event:</div>
<div class="nearby_header highlight">This event is currently full, but there are other ways you can</div>

<div id="assistance_wrap_316" class="assistance_wrap">
<div class="top"></div>
<div class="header highlight">Types of assistance offered at this event:</div>
<div class="nearby_header highlight">This event is currently full, but there are other ways you can</div>

在我的JS中，我将名称 new_info 分配给带有“aid_wrap”类的示例div的副本并为其指定唯一ID并显示在我的页面上。现在我想更改类的内容 nearby_header highlight ，其中父div ID是 assistance_wrap_316 我应该怎么做？

这是我尝试过的。日志的输出基本上是id assistance_wrap_316 的div的整个文本。

console.log(new_info.find('#assistance_wrap_'+ event_data.eventId , '.nearby_header highlight').text());

假设event_data.eventId的值为316

您应该删除","：

console.log($('#assistance_wrap_'+ event_data.eventId + ' .nearby_header').text());

或使用find()方法：

console.log($('#assistance_wrap_'+ event_data.eventId).find('.nearby_header').text());

更改ID中的类
