如何在google scriptlet中传递javascript变量？

<!-- 在Google Docs或Sheets中 -->
<script>
  var myVariable = "Hello, World!";
</script>

<div>
  <?= myVariable ?>
</div>

<script>
  function sendToServer() {
    var myVariable = "Hello, World!";
    google.script.run.withSuccessHandler(onSuccess).processData(myVariable);
  }

  function onSuccess(response) {
    console.log("Server response:", response);
  }
</script>

<button onclick="sendToServer()">Send to Server</button>

function processData(data) {
  // 处理数据
  Logger.log("Received data:", data);
  return "Data processed successfully";
}

<script>
  // 设置Cookie
  document.cookie = "myVariable=Hello, World!; path=/";

  // 或者使用LocalStorage
  localStorage.setItem('myVariable', 'Hello, World!');
</script>

<script>
  // 读取Cookie
  var cookies = document.cookie.split(';');
  for (var i = 0; i < cookies.length; i++) {
    var cookie = cookies[i].trim();
    if (cookie.indexOf("myVariable=") == 0) {
      var myVariable = cookie.substring("myVariable=".length, cookie.length);
      console.log(myVariable);
      break;
    }
  }

  // 或者读取LocalStorage
  var myVariable = localStorage.getItem('myVariable');
  console.log(myVariable);
</script>
