ToDoList—最简单的待办事项列表 正在进行 已经完成
js代码：a b c
load()//页面加载数据
var title = document.querySelector('#title')//获取头部input元素
var ol = document.querySelector('#todolist')//获取ol列表元素
var ul = document.querySelector('#donelist')//获取ul列表元素
title.addEventListener('keydown', function(e) {//监听头部input的回车事件

//取得前面存储的数据

//把我现在回车的新数据push给给前面存储的数据

edit()
//切换正在进行和完成
function changedata() {

@media screen and (min-width: 620px) {section{width:600px;padding:0 10px;}}
2.用vue写todolist。 HTML代码：
js代码：Title {{title}}{{num}}
- -
const app = new Vue({
el: "#app",
data() {
return {
todonum: 0,
donenum: 0,
todoflag:false,
doneflag:true,
local:[]
}
},
components: {
ullist
},
methods:{
//提交数据
submit(e){
let newtodo = {
title:e.target[0].value,
todo:false
}
this.local.unshift(newtodo)
console.log(this.local);
this.saveData()
this.count()
},
saveData(){
window.localStorage.setItem('todolist',JSON.stringify(this.local))
},
count(){
this.todonum = 0
this.donenum = 0
this.local.forEach(v=>{
v.todo?this.donenum++:this.todonum++
})
},
removeitem(index){
this.local.splice(index,1)
this.saveData()
this.count()
},
change(index){
this.local[index].todo?this.local[index].todo=false:this.local[index].todo=true
this.saveData()
this.count()
},
//编辑数据
editlist(e){
//console.log(e[0]);代表失焦事件的某一项
//console.log(e[1]);代表索引
var index = e[1]
this.local[index].title = e[0].target.value
this.saveData()
this.count()
}
},
mounted() {
let data = JSON.parse(window.localStorage.getItem('todolist'))
if(data != null){
this.local = data
this.count()
}else {
data = []
}
}
})
