获取选中的引导复选框的值

我有这个HTML表单:

<div class="animated-switch">
  <input id="switch-success" name="switch-success" checked="" type="checkbox">
  <label for="switch-success" class="label-success"></label>
</div>  

我怎么知道输入是否被检查?

我尝试这样但没有提示:

$(document).on('click','.animated-switch',function(e){
    alert($('#switch-success:checked').val() );
});

这里有一个JSFIDDLE文件,以便查看我的清晰示例:https://jsfiddle.net/s2f9q3fv/


您的代码在代码段中正常工作。 您已经忘记为您的复选框添加值,但即使没有它,您也应该能够看到具有未定义值的警报消息(请参阅下面的代码段中添加的'test'值)。

$(document).on('click','#switch-success:checked',function(e){
    alert($('#switch-success:checked').val() );
});
.animated-switch > input[type="checkbox"] {
  display: none; }

.animated-switch > label {
  cursor: pointer;
  height: 0px;
  position: relative;
  width: 40px; }

.animated-switch > label::before {
  background: black;
  box-shadow: inset 0px 0px 10px rgba(0, 0, 0, 0.5);
  border-radius: 8px;
  content: '';
  height: 16px;
  margin-top: -8px;
  position: absolute;
  opacity: 0.3;
  transition: all 0.4s ease-in-out;
  width: 40px; }

.animated-switch > label::after {
  background: white;
  border-radius: 16px;
  box-shadow: 0px 0px 5px rgba(0, 0, 0, 0.3);
  content: '';
  height: 24px;
  left: -4px;
  margin-top: -8px;
  position: absolute;
  top: -4px;
  transition: all 0.3s ease-in-out;
  width: 24px; }

.animated-switch > input[type="checkbox"]:checked + label::before {
  background: inherit;
  opacity: 0.5; }

.animated-switch > input[type="checkbox"]:checked + label::after {
  background: inherit;
  left: 20px; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<div class="animated-switch">
  <input id="switch-success" name="switch-success" checked="" value="test" type="checkbox">
  <label for="switch-success" class="label-success"></label>
</div>

如果复选框被选中,那会得到。

       $('#' + id).is(":checked")

尝试这个

$(".animated-switch").change(function () {
    alert($('#switch-success:checked').val() );
    });
