JavaScript time greeting?

Question

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!"?

Answer 1

Here it is!

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>");
}

Answer 2

The following should work:

var hours = new Date().hours;

if(hours > 12){
     alert("Good Afternoon!");   
}
else{
     alert("Good Morning!");   
}

Just for fun, here's a one liner:

(new Date().hours > 12) ? alert("Good Afternoon!") : alert("Good Morning!");
