Question

您好，感谢您访问这篇文章我有一个JavaScript代码，可通过onclick在输入按钮中激活暗模式我试图保持夜间模式（即使离开页面后仍启用）但是问题在于cookie无法正常运行

请帮助我解决这个问题

这是darckmode的html，css，js（效果很好）：

function darkmode() {
  var body = document.body;
  body.classList.toggle("body-dark-mode");
}

.switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
  margin-left: 80%; 
}

.switch input { 
  opacity: 0;
  width: 0;
  height: 0;
}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ccc;
  -webkit-transition: .4s;
  transition: .4s;
  border-radius: 5px;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
border-radius: 5px;
}

input:checked + .slider {
  background-color: #3572A5;
}

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 onclick="darkmode()" type="checkbox" ><!--checked-->
  <span class="slider"></span>
</label>

这是我遇到问题的javascript Cookie：

cookie的名称mm 如果darckmode已激活mm=="ok" 如果不是mm==""

function setCookie(cname,cvalue,exdays) {
  var d = new Date();
  d.setTime(d.getTime() + (exdays*24*60*60*1000));
  var expires = "expires=" + d.toGMTString();
  document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}

function getCookie(cname) {
  var name = cname + "=";
  var decodedCookie = decodeURIComponent(document.cookie);
  var ca = decodedCookie.split(';');
  for(var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
  c = c.substring(1);
}
if (c.indexOf(name) == 0) {
  return c.substring(name.length, c.length);
}
  }
  return "";
}

function checkCookie() {
  var mm=getCookie("darkmode");
  if (mm == "ok") {
darkmode();
  } else {
 mm = "ok";
 if (user != "" && user != null) {
   setCookie("darkmode", mm, 30);
 }
  }
}
window.onload = checkCookie();

我试图通过window.onload = checkCookie();

运行最后的代码

如果您能帮助我在黑色模式下将按钮激活checked 非常感谢
