<!DOCTYPE html>
<html>
<head><meta charset="utf-8" /><title></title><script>var bgColor;var list = [{ id: '1', country: '中国', capital: '北京',},{ id: '2', country: '美国', capital: '纽约',},{ id: '3', country: '英国', capital: '伦敦',},{ id: '4', country: '日本', capital: '东京',},{ id: '5', country: '韩国', capital: '首尔',},{ id: '6', country: '法国', capital: '柏林',}];window.onload = function myfunction() {var body = window.document.getElementsByTagName("body")[0];//创建表格var table = window.document.createElement("table");table.border = 1;body.appendChild(table);//创建标题行var thead = window.document.createElement("thead");var itemHead = list[0];for (var index in itemHead) {//创建标题单元格添加到theadvar th = window.document.createElement("th");th.innerText = index;thead.appendChild(th);}table.appendChild(thead);//遍历对象，创建行和单元格for (var i = 0; i < list.length; i++) {var item = list[i];//创建行var tr = window.document.createElement("tr");table.appendChild(tr);for (var key in item) {//创建单元格var td = window.document.createElement("td");td.innerText = item[key];tr.appendChild(td);}}}</script>
</head>
