javascript - 切换开关 - 当我启用另一个按钮时禁用一个按钮

Question

我想做的是禁用一个按钮，当我启用另一个按钮时（因此最多可以激活一个按钮），但我对 JS 的了解非常基础。任何提示将不胜感激。

    /* 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%;

}

// get all inputs and hang event handlers
document.querySelectorAll('input[type=checkbox]').forEach(element => element.addEventListener('click', disableOther))


function disableOther(event) {
  //"event" is current event(click)
  //"event.target" is our clicked element
  if (event.target.checked) {

    // if current input is checked -> disable ALL inputs
    document.querySelectorAll('input[type=checkbox]').forEach(element => element.disabled = true)
    // enabling our current input
    event.target.disabled = false;

  } else {

    // if current input is NOT checked -> enabling ALL inputs
    document.querySelectorAll('input[type=checkbox]').forEach(element => element.disabled = false)

  }
}
