在不破坏数组的情况下将数组存储到cookie中

// 将数组存储到cookie中
function storeArrayInCookie(array) {
  var arrayString = JSON.stringify(array);
  document.cookie = "myArray=" + encodeURIComponent(arrayString);
}

// 从cookie中获取数组
function getArrayFromCookie() {
  var cookies = document.cookie.split("; ");
  for (var i = 0; i < cookies.length; i++) {
    var cookie = cookies[i].split("=");
    if (cookie[0] === "myArray") {
      var arrayString = decodeURIComponent(cookie[1]);
      return JSON.parse(arrayString);
    }
  }
  return [];
}

// 示例用法
var myArray = [1, 2, 3, 4, 5];
storeArrayInCookie(myArray);

var retrievedArray = getArrayFromCookie();
console.log(retrievedArray); // 输出 [1, 2, 3, 4, 5]
