CSS 切换开关(复选框)值始终打开/选中

Kir*_*iya 4 html javascript css uiswitch dom-events

我只是在 CSS 中设置了样式checkboxtoggle switch效果很好。但是,输入的值似乎不会随onchange事件而改变,并且始终显示on

JS代码:

/* The switch - the box around the slider */
.switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
}

/* Hide default HTML checkbox */
.switch input {
  opacity: 0;
  width: 0;
  height: 0;
}

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

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

input:checked + .slider {
  background-color: #2196F3;
}

input:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

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

/* Rounded sliders */
.slider.round {
  border-radius: 34px;
}

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

它的视觉行为是完美的,但内在并不完美。造成该问题的原因是什么?任何想法?

工作示例: https: //jsfiddle.net/mg7sLa21/

使用checked属性来确定复选框状态,然后根据该状态分配一个值。

JS

document.getElementById('checkbox1').addEventListener('change', (e) => {
  this.checkboxValue = e.target.checked ? 'on' : 'off';
  console.log(this.checkboxValue)
})
