用拨动开关打开光标效果 on/off？

Question

我目前正在制作我的投资组合网站。我添加了来自 (https://codemyui.com/flashlight-mouse-pointer/) 的手电筒光标效果。我还从 codemyui 添加了一个切换开关。我想知道是否有人知道如何 link 效果和切换在一起，以便当我按下开关时 - 光标效果关闭？

谢谢！！

Homepage with cursor effect & toggle switch

您需要的是在切换开关打开时在 <html> 元素上设置一个新的 class，并且仅在存在 class 时才应用手电筒效果：

function update(e)
{
  var x = e.touches ? e.touches[0].clientX : e.clientX;
  var y = e.touches ? e.touches[0].clientY : e.clientY;

  document.documentElement.style.setProperty('--cursorX', x + 'px')
  document.documentElement.style.setProperty('--cursorY', y + 'px')
}

document.addEventListener('mousemove',update)
document.addEventListener('touchmove',update)

const torchInput = document.getElementById("torch");
torchInput.addEventListener("input", torchToggle);
function torchToggle()
{
  document.documentElement.classList.toggle("torch", torchInput.checked);
}

torchToggle();

/* Flashlight Overlay */
:root.torch {
  cursor: none;
  --cursorX: 50vw;
  --cursorY: 50vh;
}
:root.torch:before {
  content: '';
  display: block;
  width: 100%;
  height: 100%;
  position: fixed;
  pointer-events: none;
  background: radial-gradient(
    circle 10vmax at var(--cursorX) var(--cursorY),
    rgba(0,0,0,0) 0%,
    rgba(0,0,0,.5) 80%,
    rgba(0,0,0,.95) 100%
  )
}
