不知道你要的时间段是怎么分的，那我就根据我划分的时间段：
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>时间段提示</title>
<script>
var date=new Date();
var h=dategetHours();//获取当前时间
if(h>=0&& h<12){
alert('早上好！');
}else if(h>=12 && h<18){
alert('下午好！');
}else if(h>=18 && h<=24){
alert('晚上好！');
}
</script>
</head>
希望对你有用。
给你一个javascript的程序，文件名保存为1html就可以
<html>
<head>
<title>网页开屏 </title>
</head>
<script language="javascript">
var x = 10;
var dx = 5;
var y = windowscreenavailHeight;
var newWin = windowopen("", "myWin", "menubar=0,toolbar=0");
newWindocumentwrite("I   L  o  v  e   Y  o  u!");
newWinresizeTo(x, y);
var time = windowsetInterval("active()", 100);
function active() {
if(newWinclosed){
clearInterval(time);
return;
}
else if(x < screenavailWidth){
x+=dx;
}
else {
clearInterval(time);
}
newWinresizeTo(x,y);
}
</script>
</html>
这个是及其简单的聊天

你下载的只是网站程序的源码
要想公开投放网络
首先需要有一个自己的网址,就是注册购买域名
然后要有一个放置这个程序运行的服务器空间,购买虚拟主机
然后上传安装程序
即可访问网站了
Arrayprototyperow_averages = function () { // 返回二维数组每行的平均值
var result = [];
for (var i = 0; i < thislength; i++) {
var arr = this[i];
var sum = 0; // a数组总和
for (var j = 0; j < arrlength; j++) {
sum += arr[j];
}
resultpush(sum / arrlength);
}
return result; // 返回每行的平均值
}
$(function () {
var arr = [[1, 2, 3, 4], [2, 3, 1, 5], [4, 5, 2, 6], [5, 6, 7, 1]]; // 定义二维数组
var result = arrrow_averages(); // 调用
var str = '';
for (var i = 0; i < resultlength; i++) {
str += ' 平均值=' + result[i] + '<br/>';
}
$('#div')html(str);
