如何修复附加功能的 onClick 按钮？

Question

我在一个项目中工作，我想实现 open 和 close 按钮，但我做不到

目前，它是两者的关闭按钮，我需要添加单独的打开和关闭按钮，以便当用户点击打开时它会打开，当有人点击关闭时，它也应该正确关闭，当我点击连续关闭时按钮冻结一段时间

这是我的JSFiddle Demo的演示

请查看按钮无法正常工作的 js Fiddle 演示

这里是代码

function createItem(item) {
  var elemId = item.data("id");
  var clonedItem = item.clone();
  var newItem = $(`<div data-id="${elemId}"></div>`);
  newItem.append(clonedItem);
  newItem.appendTo('.item-append');
}

function countSaveItems() {
  $('.count').html($(".item-append div.item-save[data-id]").length);
}
$('.item-all .item-save').click(function() {
  $(this).toggleClass('productad')
  window.localStorage.setItem('test_' + this.dataset.id, $(this).hasClass('productad'));
});
$('.item-all .item-save').each(function() {
  var id = 'test_' + $(this).data("id");
  $(this).append(`<button class='close'>Close</button>`);
  if (localStorage.getItem(id) && localStorage.getItem(id) == "true") {
    $(this).addClass('productad');
    createItem($(this));
    countSaveItems();
  }
});
$(".item-all .item-save").click(function() {
  var elemId = $(this).data("id");
  var existing = $(`.item-append div[data-id="${elemId}"]`);
  if (existing.length > 0) {
    existing.remove();
  } else {
    createItem($(this));
  }
  countSaveItems();
});
$(".item-append").on("click", ".close", function() {
  var id = $(this).parent().data("id");
  localStorage.removeItem(`test_${id}`);
  $(`.item-save[data-id='${id}']`).removeClass('productad');
  $(this).parent().remove();
  countSaveItems();
});

.item-save {
  position: relative;
  display: block;
  font-size: 14px;
  margin: 5px;
  padding: 5px;
  background: #a5a5a5;
  float: left;
  text-align: center;
  cursor: pointer;
}

.productad {
  background: red;
  color: #eee
}

.count {
  display: block;
  background: #cbcbcb;
  float: left;
  font-size: 15px;
  padding: 5px 18px;
  margin: 10px;
}

非常感谢任何帮助或建议

要做到这一点，你需要在 HTML 中添加打开按钮，因为那将是静态的，然后当用户点击“打开”或关闭项目时，在“打开”和“关闭”之间切换，还需要修复本地存储，而不是在关闭按钮中删除，只需将值切换为 false 并根据该值进行验证。检查以下代码以查看是否是您要查找的内容：

function createItem(item){
    var elemId = item.data("id");
    var clonedItem = item.clone();
    var newItem = $(`<div data-id="${elemId}"></div>`);
    newItem.append(clonedItem);
    clonedItem.children('.open').remove();
    clonedItem.append(`<button class='close'>Close</button>`);
    newItem.appendTo('.item-append');
}

function countSaveItems(){
    $('.count').html($(".item-append div.item-save[data-id]").length);
}

$('.item-all .item-save').click(function() {
  var id = $(this).data("id");
  var lsId = `test_${id}`;
  
  $(this).toggleClass('productad');
  
  if (!$(this).hasClass('productad')){
    window.localStorage.setItem(lsId, false);
    $(this).children(".open").html("Open");
    createItem($(this));
  }else{
    window.localStorage.setItem(lsId, true);
    $(this).children(".open").html("Close");
    $(`.item-append div[data-id='${id}']`).remove();
  }
  countSaveItems();
  
});

$('.item-all .item-save').each(function() {
  var id = 'test_' + $(this).data("id");
  
  if (localStorage.getItem(id) && localStorage.getItem(id) == "true") {
    $(this).addClass('productad');
    createItem($(this));
  }
  countSaveItems();
});

$(".item-all .item-save").click(function() {
  var elemId = $(this).data("id");
  var existing = $(`.item-append div[data-id="${elemId}"]`);
  if (existing.length > 0){
    existing.remove();
  }else{
    
    createItem($(this));
  }
  countSaveItems();
});

$(".item-append").on("click", ".close", function() {
    var id = $(this).parent().data("id");
    window.localStorage.setItem(`test_${id}`, false);
    $(`.item-save[data-id='${id}']`).removeClass('productad');
    $(`.item-save[data-id='${id}']`).children(".open").html("Open");
    $(this).parent().parent().remove();
  countSaveItems();
});

.item-save {
  position: relative;
  display: block;
  font-size: 14px;
  margin: 5px;
  padding: 5px;
  background: #a5a5a5;
  float: left;
  text-align: center;
  cursor: pointer;
}

.productad {
  background: red;
  color: #eee
}

.count {
  display: block;
  background: #cbcbcb;
  float: left;
  font-size: 15px;
  padding: 5px 18px;
  margin: 10px;
