.time_div{width:100%; padding:10px; text-align:center; margin:5px auto; }
var show_time_server = function(){
var xhr = null;
if(window.XMLHttpRequest){
xhr = new window.XMLHttpRequest();
}else{ // ie
xhr = new ActiveObject("Microsoft")
}
// 通过get的方式请求当前文件
xhr.open("get","/");
xhr.send(null);
// 监听请求状态变化
xhr.onreadystatechange = function(){
var time = null;
var curDate = null;
if(xhr.readyState===2){
// 获取响应头里的时间戳
time = xhr.getResponseHeader("Date");
console.log(xhr.getAllResponseHeaders())
curDate = new Date(time);
document.getElementById("time_server").innerHTML = "服务器时间是:"+curDate.getFullYear()+"-"+(curDate.getMonth()+1)+"-"+curDate.getDate()+" "+curDate.getHours()+":"+curDate.getMinutes()+":"+curDate.getSeconds();
setTimeout('show_time_server()', 1000);
}
}
}
var show_time_local = function(){
curDate = new Date();
document.getElementById("time_local").innerHTML = "本地时间是:"+curDate.getFullYear()+"-"+(curDate.getMonth()+1)+"-"+curDate.getDate()+" "+curDate.getHours()+":"+curDate.getMinutes()+":"+curDate.getSeconds();
setTimeout('show_time_local()', 1000);
}
show_time_server();
show_time_local();
