·创建一个XMLHttpRequest对象

let request = new XMLHttpRequest();
let request = new ActiveXObject(‘Microsoft.XMLHTTP‘); // IE5 IE6
let request = new ActiveXObject(‘Msxm12.XMLHTTP‘); // IE5 IE6

·指定HTTP请求并向一个Web服务器提交

request.open(‘GET‘, url, false); // false同步
request.send(null); // get请求

·同步地或异步地获得服务器的响应
