更改ID中的班级

Question

这是类名为“assistance_wrap”的样本格。

<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> 

我已经克隆了这个div，每个克隆版本都附有一个唯一的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我给你的名字new_info与类样品div的副本“assistance_wrap” 并分配唯一的ID，并显示我的网页上。 现在我想改变类里面的文字near_header亮点谁的父母div id是 assistance_wrap_316我应该怎么做？

这是我试过的。日志的输出基本上是div的整个文本，编号为assistance_wrap_316。

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

假设event_data.eventId的价值为316

Answer 1

你应该删除","：

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());
