我正在尝试创建一个可自定义的列表,其中包含可以使用类隐藏的链接,如果您单击按钮.此列表还有一个可排序选项,您可以移动列表中的链接,这些链接将保存到localstorage.
问题是,如果单击每个li上的“添加/删除”按钮,我不知道如何使用localstorage中的列表顺序保存类更改.
此外,如果有人可以帮助我改进代码,我将不胜感激,我是localstorage的新手,并且只在教程和文档中阅读了很多内容.
这是一个有效的例子:
http://codepen.io/RogerHN/pen/EgbOzB
var list = document.getElementById('linklist');
var items = list.children;
var itemsArr = [];
for (var i in items) {
itemsArr.push(items[i]);
}
// localStorage
var ls = JSON.parse(localStorage.getItem('userlist') || '[]');
for (var j = 0; j < ls.length; j++) {
for (i = 0; i < itemsArr.length; ++i) {
if(itemsArr[i].dataset !== undefined){
if (ls[j] === itemsArr[i].dataset.id) {
list.appendChild(itemsArr[i]);
}
}
}
}
$('.list-block.sortable').on('sort', function () {
var newIdsOrder = [];
$(this).find('li').each(function(){
newIdsOrder.push($(this).attr('data-id'));
});
// store in localStorage
localStorage.setItem('userlist', JSON.stringify(newIdsOrder));
});
最佳答案 你想要这样的东西:
var myApp = new Framework7({
swipePanel: 'left'
});
// Export selectors engine
var $$= Dom7;
var mainView = myApp.addView('.view-main');
var list = document.getElementById('linklist');
var items = list.children;
var itemsArr = [];
for (var i in items) {
itemsArr.push(items[i]);
}
// localStorage
var ls = JSON.parse(localStorage.getItem('userlist') || '[]');
var classes = JSON.parse(localStorage.getItem('classes') || '["","","","","","","","","",""]');
for (var j = 0; j < ls.length; j++) {
for (i = 0; i < itemsArr.length; ++i) {
if(itemsArr[i].dataset !== undefined){
if (ls[j] === itemsArr[i].dataset.id) {
itemsArr[i].className = classes[i];
list.appendChild(itemsArr[i]);
// handle [add/remove] thing
if (classes[i] != "") {
$(itemsArr[i]).find(".checky").removeClass("selected");
}
}
}
}
}
$('.list-block.sortable').on('sort', saveInfo);
$(".restore").click(function(e) {
$(".confirm").show();
$(".shadow").show();
});
$(".no,.shadow").click(function(e) {
$(".confirm").hide();
$(".shadow").hide();
});
$(".yes").click(function(e) {
$(".confirm").hide();
});
$(".lbl").click(function(e) {
$(".toggle-text").toggleClass("blue");
$(".restore").toggle();
$(".checky").toggle();
$("li.hidden").toggleClass("visible");
});
$('.checky').click(function() {
if (!$(this).hasClass("selected")) {
$(this).parent().removeClass("hidden").addClass("visible");
}
else {
$(this).parent().addClass("hidden visible");
}
$(this).toggleClass("selected");
saveInfo();
});
function saveInfo() {
var newUserList = [];
var newClassList = [];
$("#linklist").find('li').each(
function() {
newUserList.push($(this).attr('data-id'));
if ($(this).hasClass("hidden")) {
newClassList.push("hidden");
}
else {
newClassList.push("");
}
});
// store in localStorage
localStorage.setItem('userlist', JSON.stringify(newUserList));
localStorage.setItem('classes', JSON.stringify(newClassList));
console.log("saved.");
}
function reset() {
console.log("Removing data from local storage.");
localStorage.setItem('userlist', '["1","2","3","4","5","6","7","8","9","10"]');
localStorage.setItem('classes', '["","","","","","","","","",""]');
window.location.reload(true);
};
从技术上讲,我应该添加解释……
