javascript - 同一按钮类上的单击事件，但在 jquery 中调用不同的操作

Question

我遇到了问题。我在这里定义了代码:

$('.js-cars-item [type="checkbox"]').change(function() {
  var idx = $(this).closest('li').index(); //Get the index - Number in order
  var chk = $(this).is(":checked"); //Get if checked or not
  var obj = this; //Checkbox object

  $('.js-cars-item').each(function() { //Loop every js-cars-item
    //Find the checkbox with the same index of clicked checkbox. Change disabled property
    $(this).find('li:eq(' + idx + ') [type="checkbox"]').not(obj).prop("checked", false);
  });

  var checkeds = [];
  $(".cars-item input:checkbox:checked").each(function(index) {
    checkeds[index] = $(this).attr('id');
  });
  console.clear();
  console.log("These are checked:", checkeds);
})

$('.js-add-category').click(function() {

  var categoryContent = `<div class="cars">

<div class="cars-item js-cars-item">
  <ul>
    <li>
      <input type="checkbox" id="car-1-3">
      <label for="car-1-3"><i class="icon-tick"></i></label>
    </li>
    <li>
      <input type="checkbox" id="car-2-3">
      <label for="car-2-3"><i class="icon-tick"></i></label>
    </li>
    <li>
      <input type="checkbox" id="car-3-3">
      <label for="car-3-3"><i class="icon-tick"></i></label>
    </li>
  </ul>
</div>

<button type="button" class="js-add-section">Add Section</button>
</div> <br>`

  $('.main').append(categoryContent);

});


$(document.body).on('click', 'button.js-add-section', function() {
  var sectionContent = `<div class="cars-item js-cars-item">
  <ul>
    <li>
      <input type="checkbox" id="car-1-6>
      <label for="car-1-6"><i class="icon-tick"></i></label>
    </li>
      <li>
      <input type="checkbox" id="car-2-6>
      <label for="car-2-6"><i class="icon-tick"></i></label>
    </li>
      <li>
      <input type="checkbox" id="car-3-6>
      <label for="car-3-6"><i class="icon-tick"></i></label>
    </li>
  </ul> </div>`

  $('.cars').append(sectionContent);

});

.cars-item {
  border-bottom: 1px solid gray;
}

ul {
  /* Added to fully show console in snippet */
  margin: 2px;
}

li {
  display: inline;
}

.cars {
  box-sizing: content-box;
  width: 250px;
  height: auto;
  padding: 10px;
  border: 5px solid blue;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<button type="button" class="js-add-category">Add Category</button> <br> <br>

<div class="main">

  <div class="cars">

    <div class="cars-item js-cars-item">
      <ul>
        <li>
          <input type="checkbox" id="car-1-3">

        <li>
          <input type="checkbox" id="car-2-3">
          <label for="car-2-3"><i class="icon-tick"></i></label>
        </li>
        <li>
          <input type="checkbox" id="car-3-3">
          <label for="car-3-3"><i class="icon-tick"></i></label>
        </li>
      </ul>
    </div>



    <button type="button" class="js-add-section">Add Section</button>

    <br>

    <div class="section">



    </div>



  </div>
  <br>

问题是我面临的问题是，当我单击框中的“添加部分”按钮时，它会在其他框中添加重复的行。我想要实现的是仅在我单击“添加部分”按钮的框中添加一行复选框。

当我单击添加类别时，它会生成另一个带有另一个按钮添加部分的框

请演示代码以获取概述。请有人帮我解决这个问题，我完全陷入困境。

谢谢。

只需使用 $(this).parent().append(sectionContent); 而不是 $('.cars').append(sectionContent);

工作代码

$('.js-cars-item [type="checkbox"]').change(function() {
  var idx = $(this).closest('li').index(); //Get the index - Number in order
  var chk = $(this).is(":checked"); //Get if checked or not
  var obj = this; //Checkbox object

  $('.js-cars-item').each(function() { //Loop every js-cars-item
    //Find the checkbox with the same index of clicked checkbox. Change disabled property
    $(this).find('li:eq(' + idx + ') [type="checkbox"]').not(obj).prop("checked", false);
  });

  var checkeds = [];
  $(".cars-item input:checkbox:checked").each(function(index) {
    checkeds[index] = $(this).attr('id');
  });
  console.clear();
  console.log("These are checked:", checkeds);
})

$('.js-add-category').click(function() {

  var categoryContent = `<div class="cars">

<div class="cars-item js-cars-item">
  <ul>
    <li>
      <input type="checkbox" id="car-1-3">
      <label for="car-1-3"><i class="icon-tick"></i></label>
    </li>
    <li>
      <input type="checkbox" id="car-2-3">
      <label for="car-2-3"><i class="icon-tick"></i></label>
    </li>
    <li>
      <input type="checkbox" id="car-3-3">
      <label for="car-3-3"><i class="icon-tick"></i></label>
    </li>
  </ul>
</div>

<button type="button" class="js-add-section">Add Section</button>
</div> <br>`

  $('.main').append(categoryContent);

});

$(document.body).on('click', 'button.js-add-section', function() {
  var sectionContent = `<div class="cars-item js-cars-item">
  <ul>
    <li>
      <input type="checkbox" id="car-1-6>

  $(this).parent().append(sectionContent);

.cars {
