var big = document.getElementById("table");//获取表格
var title = document.getElementsByClassName("hh")[0].children;//获取表头的名称 修改日期  类型  大小
	console.log(title)
var main = document.getElementsByClassName("one");//获取表格内容的所有ul 
	console.log(main);
var lis = document.getElementsByTagName("li");//获取表格内容的所有li
	console.dir(lis);
var dian = document.getElementsByClassName("dian")[0];
	console.dir(dian);
var dian2 = document.getElementsByClassName("dian2")[0];
var dian3 = document.getElementsByClassName("dian3")[0];
var dian4 = document.getElementsByClassName("dian4")[0];
	console.dir(dian4);

3.创建一个数组对象

var data = [
				{
					"name": parseFloat(main[0].children[0].innerHTML),
					"time": parseFloat(main[0].children[1].innerHTML),
					"type": main[0].children[2].innerHTML,
					"size": main[0].children[3].innerHTML,
				},
				{
					"name": parseFloat(main[1].children[0].innerHTML),
					"time": parseFloat(main[1].children[1].innerHTML),
					"type": main[1].children[2].innerHTML,
					"size": main[1].children[3].innerHTML,
				}, 
				{
					"name": parseFloat(main[2].children[0].innerHTML),
					"time": parseFloat(main[2].children[1].innerHTML),
					"type": main[2].children[2].innerHTML,
					"size": main[2].children[3].innerHTML,
				},
				{
					"name": parseFloat(main[3].children[0].innerHTML),
					"time": parseFloat(main[3].children[1].innerHTML),
					"type": main[3].children[2].innerHTML,
					"size": main[3].children[3].innerHTML,
				},
				{
					"name": parseFloat(main[4].children[0].innerHTML),
					"time": parseFloat(main[4].children[1].innerHTML),
					"type": main[4].children[2].innerHTML,
					"size": main[4].children[3].innerHTML,
				}, 
				{
					"name": parseFloat(main[5].children[0].innerHTML),
					"time": parseFloat(main[5].children[1].innerHTML),
					"type": main[5].children[2].innerHTML,
					"size": main[5].children[3].innerHTML,
				}, 
				{
					"name": parseFloat(main[6].children[0].innerHTML),
					"time": parseFloat(main[6].children[1].innerHTML),
					"type": main[6].children[2].innerHTML,
					"size": main[6].children[3].innerHTML,
				},
			]

data为一个数组 数组里面有7个对象 每个对象都有4个属性 name,time,type,size

4.封装正序方法

function zhengxu(name){
		 	for(var i = 0; i < data.length; i++) {
				for(var j = 0; j < data.length - i - 1; j++) {
					if(data[j][name] > data[j + 1][name]) {
						var x = data[j];
						data[j] = data[j + 1];
						data[j + 1] = x;
					}
				}
			}
			
		}

使用冒泡排序的原理 对每个属性正序排列

5.封装倒序方法

function daoxu(name){
		 	for(var i = 0; i < data.length; i++) {
				for(var j = 0; j < data.length - i - 1; j++) {
					if(data[j][name] < data[j + 1][name]) {
						var x = data[j];
						data[j] = data[j + 1];
						data[j + 1] = x;
					}
				}
			}
			
		}

6.遍历赋值

function show() {
				for (var i=0;i<main.length; i++){
					main[i].children[0].innerHTML=data[i].name;
				}
				for (var i=0;i<main.length; i++){
					main[i].children[1].innerHTML=data[i].time;
				}
				for (var i=0;i<main.length; i++){
					main[i].children[2].innerHTML=data[i].type;
				}
				for (var i=0;i<main.length; i++){
					main[i].children[3].innerHTML=data[i].size;
				}
			}

7.绑定点击事件

dian.onclick = function () {

			zhengxu("name");
			dian.flag=1;
		}else{
			daoxu("name");
			dian.flag=0;
		}
		
		show();
	}
dian2.onclick = function () {

			zhengxu("time");
			dian.flag=1;
		}else{
			daoxu("time");
			dian.flag=0;
		}
		show();
	}
	
dian3.onclick = function () {
		if(dian.flag=="0"){
		zhengxu("type");
		dian.flag=1;
		}else{
			daoxu("type");
			dian.flag=0;
		}
		show();
	}
	
dian4.onclick = function () {
		if(dian.flag=="0"){
		zhengxu("size");
		dian.flag=1;
		}else{
			daoxu("size");
			dian.flag=0;
		}
		show();
	}
