javascript - 按钮仅在双击后切换

下面是使用网页控制led开/关的脚本。该脚本链接到实际控制 LED 的 Python。一切正常，但问题是按钮只有在双击后才会切换到右侧，即“ON”位置。

第一次单击时，复选框会被选中，LED 会亮起，但会滑动不向右移动。
第二次单击时，幻灯片向右移动。

而单击按钮即可切换到左侧(没有问题)。有人可以帮忙吗？

最佳答案

$('#On').click(); 和 $('#Off').click(); 不需要 get( 0) 在其中

$(document).ready(function() {
  $("#test").click(function() {
    if ($(this).is(":checked")) {
      $('#On').click(); 
    } 
    if (!$(this).is(":checked")) {
     $('#Off').click(); 
    }
  });
   $('#On').click(function(){
      console.log('id On clicked')  
   });
   $('#Off').click(function(){
      console.log('id Off clicked')  
   });
});

.onoffswitch {
  position: relative;
  width: 90px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
}

.onoffswitch-checkbox {
  display: none;
}

.onoffswitch-label {
  display: block;
  overflow: hidden;
  cursor: pointer;
  border: 2px solid #999999;
  border-radius: 20px;
}

.onoffswitch-inner {
  display: block;
  width: 200%;
  margin-left: -100%;
  transition: margin 0.3s ease-in 0s;
}

.onoffswitch-inner:before,
.onoffswitch-inner:after {
  display: block;
  float: left;
  width: 50%;
  height: 30px;
  padding: 0;
  line-height: 30px;
  font-size: 14px;
  color: white;
  font-family: Trebuchet, Arial, sans-serif;
  font-weight: bold;
  box-sizing: border-box;
}

.onoffswitch-inner:before {
  content: "ON";
  padding-left: 10px;
  background-color: #34A7C1;
  color: #FFFFFF;
}

.onoffswitch-inner:after {
  content: "OFF";
  padding-right: 10px;
  background-color: #EEEEEE;
  color: #999999;
  text-align: right;
}

.onoffswitch-switch {
  display: block;
  width: 18px;
  margin: 6px;
  background: #FFFFFF;
  position: absolute;
  top: 0;
  bottom: 0;
  right: 56px;
  border: 2px solid #999999;
  border-radius: 20px;
  transition: all 0.3s ease-in 0s;
}

.onoffswitch-checkbox:checked+.onoffswitch-label .onoffswitch-inner {
  margin-left: 0;
}

.onoffswitch-checkbox:checked+.onoffswitch-label .onoffswitch-switch {
  right: 0px;
}
