Menu
I just styled the checkbox as toggle switch in CSS, It works fine. However, the value of input seems to not change on onchange event and shows always on.
JS code:
/* 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%;

<label class="switch">
<input type="checkbox" onchange="console.log(this.value);">
<span class="slider round"></span>
</label>

</html>It's visual behaviour is perfect, but not internal. What is the reason that caused the issue? any idea?

Working example: https://jsfiddle.net/mg7sLa21/
Use the checked property to determine the checkbox state, then assign a value based on that state.
JS
document.getElementById('checkbox1').addEventListener('change', (e) => {
this.checkboxValue = e.target.checked ? 'on' : 'off';
console.log(this.checkboxValue)
})
