复选框上的Javascript克隆此div,在未选中时删除此div

Question

当复选框被选中克隆正确的股利,并显示在例如:<div id="favorite"></div>当复选框未选中删除克隆,伴随着localStorage.有人可以帮我解决这个问题吗？

function onClickAvGamesCheckBox() {
  var arr = $('.AvGamesCheckBox').map(function() {
    return this.checked;
  }).get();
  localStorage.setItem("checked", JSON.stringify(arr));
}

$(document).ready(function() {
  var arr = JSON.parse(localStorage.getItem('checked')) || [];
  arr.forEach(function(checked, i) {
    $('.AvGamesCheckBox').eq(i).prop('checked', checked);
  });
  $(".AvGamesCheckBox").click(onClickAvGamesCheckBox);
});

//* Clone script
$(".avclone :checkbox").change(function() {
  var name = $(this).closest("div").attr("name");
  if (this.checked)
    $(".columns[name=" + name + "]").clone().appendTo("#favorite");

你有一个点击处理程序,所以我们将其连接起来进行存储(由于沙箱而无法在这里工作),我们也可以使用数据并按此过滤,为每个columns容器添加索引以用于过滤克隆的项目,以便我们可以定位它们并移除无论先添加哪一个.

这是一个自定义事件和稍微复杂的存储示例的小提琴:https: //jsfiddle.net/MarkSchultheiss/5Luyn18j/47/作为一个小提琴避免SO上的沙箱.

(function($) {
  $.fn.filterByData = function(prop, val) {
    return this.filter(
      function() {
        return $(this).data(prop) == val;
      }
    );
  }
})(window.jQuery);

function onClickAvGamesCheckBox(event) {
  var arr = $('.AvGamesCheckBox').map(function() {
    return this.checked;
  }).get();
  // localStorage.setItem("checked", JSON.stringify(arr));
}

$(function() {
  //add some data
  $('.AvGamesCheckBox').each(function(index, element) {
    $(this).closest('.column').data("checkindex", index);
  });
  // replace [] with the commented out for real stuff
  var arr = []; //JSON.parse(localStorage.getItem('checked')) || [];
  arr.forEach(function(checked, i) {
    $('.AvGamesCheckBox').eq(i).prop('checked', checked);
