// 第一步: 获得XMLHttpRequest对象
var ajax = new XMLHttpRequest();
// 第二步: 设置状态监听函数
ajax.onreadystatechange = function () {
console.log(ajax.readyState);
console.log(ajax.status);
// 第五步:在监听函数中,判断readyState=4 && status=200表示请求成功
if (ajax.readyState === 4 && ajax.status === 200) {
// 第六步: 使用responseText、responseXML接受响应数据,并使用原生JS操作DOM进行显示
console.log(ajax.responseText);
// console.log(ajax.responseXML);// 返回不是XML,显示null
// console.log(JSON.parse(ajax.responseText));
// console.log(eval("(" + ajax.responseText + ")"));
}
}
// 第三步: open一个链接
// ajax.open("GET", "http://wtkj.qiyejianzhan.wang/dtest.php?time=5", false);//true异步请求,false同步
// 第四步: send一个请求。 可以发送对象和字符串,不需要传递数据发送null
// ajax.send(null);
