网站布局较为简单,附上html与css作为参考,事件列表通过js动态添加
ToDoList使用本地存储localStorage,可以使数据在浏览器关闭后再次打开不会丢失
$(function () {
//1.按下回车 把数据存储到本地存储里面
//存储的数据格式 var todolist = [{title:"xxx",done:false}]
load()
$("#title").on("keydown", function (e) {
if (e.keyCode === 13) {
if ($(this).val() === "") {
alert("不能为空")
} else {
//先读取本地存储的来源数据
var local = getData();
// console.log(local);
//把local数组进行更新数据把最新的数据追加给local数组
local.push({ title: $(this).val(), done: false });
//把这个数组local 存储给本地存储
saveData(local);
//2.toDoList 本地存储数据渲染加载到页面
load();
$(this).val("")
}
}
});
//3.toDoList删除操作
$("ol,ul").on("click", "a", function () {
//先获取本地存储
var data = getData();
//修改数据
var index = $(this).attr("id")
data.splice(index, 1);
//保存到本地存储
saveData(data)
//重新渲染页面
load()
})
//4.toDoList待完成和已完成选项操作
$("ul,ol").on("click", "input", function () {
// 先获取本地数据
var data = getData();
// 修改数据
var index = $(this).siblings("a").attr("id");
data[index].done = $(this).prop("checked");
// 保存到本地存储
saveData(data)
// 重新渲染页面
load()
})
//读区本地存储的数据
function getData() {
var data = localStorage.getItem("todolist")
if (data != null) {
//本地存储里面数据是字符串格式的,但是我们需要的是对象格式的
return JSON.parse(data)
} else {
return []
}
}
//保存本地存储数据
function saveData(data) {
localStorage.setItem("todolist", JSON.stringify(data))
}
//渲染加载数据
function load() {
var data = getData();
var todoCount = 0;//正在进行个数
var doneCount = 0;//已经完成个数
console.log(data);
//遍历之前先要清空ol里面的元素内容
$("ol,ul").empty();
//遍历
$.each(data, function (i, n) {
// console.log(n);
if (n.done) {
$("ul").prepend("<li><input type='checkbox' checked='checked'><p>" + n.title + "</p><a href='javascript:;' id=" + i + "></a></li>")
doneCount++
} else {
$("ol").prepend("<li><input type='checkbox'><p>" + n.title + "</p><a href='javascript:;' id=" + i + "></a></li>")
todoCount++
}
});
$("#todocount").text(todoCount)
$("#donecount").text(doneCount)
}
})
