是否在点击其他单元格时隐藏datePicker？

// 假设datePicker的id为"datepicker"
const datePicker = document.getElementById("datepicker");
const cells = document.querySelectorAll(".cell");

document.addEventListener("click", function(event) {
  const target = event.target;
  
  // 检查点击的元素是否是datePicker所在的元素或其子元素
  if (target !== datePicker && !datePicker.contains(target)) {
    // 隐藏datePicker
    datePicker.style.display = "none";
  }
});

// 在单元格点击事件中显示datePicker
cells.forEach(function(cell) {
  cell.addEventListener("click", function() {
    // 显示datePicker
    datePicker.style.display = "block";
  });
});
