JavaScript time greeting?
提问by user23557676
How do you make something with JavaScript that when your time is below 12 o'clock, it says "good morning!" and when it is after 12 o'clock, it says "good afternoon!"?
你如何用 JavaScript 制作一些东西，当你的时间低于 12 点时，它会说“早上好！” 当它是 12 点以后，它说“下午好！”？

Here it is!
这里是！
var d = new Date();
var time = d.getHours();
if (time < 12) {
document.write("<b>Good morning!</b>");
}
if (time > 12) {
document.write("<b>Good afternoon!</b>");
}
if (time == 12) {
document.write("<b>Go eat lunch!</b>");

The following should work:
以下应该工作：
var hours = new Date().hours;
if(hours > 12){
alert("Good Afternoon!");
}
else{
alert("Good Morning!");
}
Just for fun, here's a one liner:
只是为了好玩，这是一个单班轮：
(new Date().hours > 12) ? alert("Good Afternoon!") : alert("Good Morning!");

<SCRIPT LANGUAGE="JavaScript">
currentTime=new Date();
//getHour() function will retrieve the hour from current time
if(currentTime.getHours()<12)
document.write("<b>Good Morning!! </b>");
else if(currentTime.getHours()<17)
document.write("<b>Good Afternoon!! </b>");
else
document.write("<b>Good Evening!! </b>");
</SCRIPT>

//if hour is between 12pm-6pm ,print good afternoon
//else good evening
let hour = 5;
if(hour>=6 && hour<12) {
console.log('Good Morning')
}
else if(hour>+12 && hour<18) {
console.log('Good Afternoon')
}
else {

const date = new Date;
let hours = date.getHours();
let status = (hours < 12)? "Morning" :
((hours <= 18 && hours >= 12 ) ? "Afternoon" : "Night");
console.log(status);
