Javascript 选择具有给定类的子级

我有三个类似的部分。我想选择一个具有给定类的元素，但只在我单击的元素的范围内

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

我当前的代码选择具有相同类的所有元素

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

如果我在类

mine

上添加了一个事件处理程序，并且需要在

target

类上执行一些操作，则仅针对我单击的类

one

范围内的inner2， 那我该怎么做呢

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

HTML:

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

使用下面的代码。用于搜索子元素

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

$('.one').on('click',function(){
   var inner2Obj = $(this).find('div.inner2');
   inner2Obj.slideToggle(function(){
      // your code
   });
   console.log(inner2Obj) // this will log inner2 object within clicked one DIV
});

试试这个：您可以利用获取

inner2

元素并对其执行操作

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

$(".mine" ).click(function() {  
   $(this).siblings('.inner2').slideToggle(function(){
      if(temp==0){
        $(this).closest(".proElement").addClass('darkBg');
        temp=1;
     }
    else{
       $(this).closest(".proElement").removeClass('darkBg');
       temp=0;
      }
   });// end of slideToggle
}); // 

您还可以在此处使用.sibbins（）：

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

使用同级

<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

$(".mine" ).click(function() {  
$(this).siblings('.inner2').slideToggle(function(){
if(temp==0){
    $(this).closest(".proElement").addClass('darkBg');
    temp=1;
}
else{
    $(this).closest(".proElement").removeClass('darkBg');
    temp=0;
}
});
});


<div class="one">
 <div class="some">
      <div class="mine"></div>
  </div>
 <div class="inner1">
 </div>
 <div class="inner2">
   <div class="target"></div>
 </div>
</div>

<div class="one">
  <div class="some">
      <div class="mine"></div>
  </div>
  <div class="inner1">
  </div>
  <div class="inner2">
     <div class="target"></div>
  </div>
  </div>

JS中使用的选择器在共享HTML中不存在。请发布相关标记。我没有看到任何单击事件绑定到类1。。你想重温你的问题吗？对不起，任务有变化，标记有变化，检查一下
