如何根据复选框开关点击打开一个div？

Question

我创建了一个引导开关，并且我在开关底部有一个 div，所以当开关打开时我希望 div 显示，当它关闭时我希望 div 隐藏。我找到了一些只显示复选框的解决方案。

我该怎么做？

例如，如果开关复选框被选中，那么我需要显示 div 的内容，否则隐藏 div。

</div>

Answer 1

这对于 jquery 来说非常简单。查看以下示例

$(document).ready(() => {
    $("#content").hide();

    $("#chkbox").click((e) => {
        if ($("#chkbox").is(":checked")) {
            $("#content").show();
        } else {
            $("#content").hide();
        }
    });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="" id="chkbox" />
<div id="content">
    <p>Hidden Content</p>
</div>

Answer 2

您可以将.click() 附加到滑块上，然后使用.toggle() 显示/隐藏元素，这是一个有效的sn-p：

$(document).ready(function(){
  $('.show-content').hide();
  $('.slider').click(function(e) {
    $('.show-content').toggle();
  })
})

Answer 3

使用 JQuery 你可以实现这样的目标：

$('.show-content').hide() // Init with hidden .show-content

$('input.success').change(function() {
  if (this.checked) {
    $('.show-content').show()
  } else {
    $('.show-content').hide()
  }
});

.tags-list-group {
  margin-bottom: 50px;
}

.tags-list-group .switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
  float: right;
}

.tags-list-group .switch input {
  display: none;
}

.tags-list-group .slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ccc;
  -webkit-transition: .4s;
  transition: .4s;
}

.tags-list-group .slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

.tags-list-group input:checked+.slider:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}

.tags-list-group .slider.round {
  border-radius: 34px;
}

.tags-list-group .slider.round:before {
  border-radius: 50%;
}

.tags-list-group input.success:checked+.slider {
  background-color: #8bc34a;
}

<div class="tags-list-group">
  <div class="tags-group-card">
    <!-- Default panel contents -->

        User Defined
        <label class="switch ">
          <input type="checkbox" class="success">
          <span class="slider round"></span>
        </label>
      </li>
    </ul>
  </div>
  <div class="list-group-item show-content">
    <p>Content 1(hide div)</p>
  </div>

</div>

它正在使用函数.show()、.hide() 和change 事件。

Answer 4

这是您想要的，基于您的代码。但是，在我看来，您可以通过使用 Bootstrap 的collapse component 并将您的开关嵌入其中来获得一个更整洁的。

$("#myCustomCheckbox").change(function(){

  // in case the switch is on
  if(this.checked) {
        $("#myDivOfContent").addClass("content-area--show");
        
  // in case switch is off
    }else{
        $("#myDivOfContent").removeClass("content-area--show");
    }
});

/*** begin::div of content styles ****/

.content-area {
  height: 0;
  width: 100%;
  overflow: hidden;
  transition: height .3s ease-in-out;
 }
 
 .content-area p {
  padding: 20px;
}
 
.content-area--show {
  height: 70px;
  border: 1px solid #ccc;
  border-top: 0;
}

.switch {
 margin-bottom: 0;
 }
/*** end::div of content styles ****/

.tags-list-group {
    margin-bottom: 50px;
}

.tags-list-group .switch {
    position: relative;
    display: inline-block;
    width: 60px;
    height: 34px;
    float: right;
}

.tags-list-group .switch input {
    display: none;
}

.tags-list-group .slider {
    position: absolute;
    cursor: pointer;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background-color: #ccc;
    -webkit-transition: .4s;
    transition: .4s;
}

.tags-list-group .slider:before {
    position: absolute;
    content: "";
    height: 26px;
    width: 26px;
    left: 4px;
    bottom: 4px;
    background-color: white;
    -webkit-transition: .4s;
    transition: .4s;
}

.tags-list-group input:checked + .slider:before {
    -webkit-transform: translateX(26px);
    -ms-transform: translateX(26px);
    transform: translateX(26px);
}

.tags-list-group .slider.round {
    border-radius: 34px;
}

.tags-list-group .slider.round:before {
    border-radius: 50%;
}

Answer 5

使用prop 来检查this：

$(function() {
  $('.success').change(function() {
    if ($(this).prop('checked')) {
      $(".show-content").show();
    } else {
      $(".show-content").hide();
    }
  })
});

.tags-list-group {
  margin-bottom: 50px;
}

.tags-list-group .switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
  float: right;
}

.tags-list-group .switch input {
  display: none;
}

.tags-list-group .slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ccc;
  -webkit-transition: .4s;
  transition: .4s;
}

.tags-list-group .slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

.tags-list-group input:checked+.slider:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}

.tags-list-group .slider.round {
  border-radius: 34px;
}

.tags-list-group .slider.round:before {
  border-radius: 50%;
}

.tags-list-group input.success:checked+.slider {
  background-color: #8bc34a;
