在這里，我在一個專案上作業，我想在其中實作打開和關閉按鈕，但我無法做到
目前，它是兩者的關閉按鈕，我需要添加單獨的打開和關閉按鈕，以便當用戶單擊打開時它是打開的，當有人單擊關閉時它也應該正確關閉，當我連續單擊關閉然后按鈕凍結時某個時候
這是我的JSFiddle Demo 的演示
請檢查按鈕無法正常作業的 js Fiddle 演示
這是代碼
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();

uj5u.com熱心網友回復：
要實作效果，您需要將打開按鈕添加到 HTML 中，因為那將是靜態的，然后當用戶單擊“打開”或關閉專案時在“打開”和“關閉”之間切換，還需要修復本地storage 而不是在關閉按鈕中洗掉，只需將值切換為 false 并根據該值進行驗證。檢查以下代碼，看看這是否是您要查找的內容：
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');
