我试图证明这个条件，
00 - 07 am - 显示“今天早上”|| 07 - 19 pm - 显示“今天晚上” || 19 - 24 am - 显示“明天早上”
但我猜我的代码有问题。
<html>
<head>
<title>Greeting Message using JavaScript</title>
</head>
<body>
<label id="lblGreetings"></label>
</body>
<script>
var myDate = new Date();
var hrs = myDate.getHours();
var greet;
if (hrs > 07 && hrs <= 19)
greet = 'Today Evening';
else if (hrs >= 19 && hrs <= 24)
greet = 'Tommorow Morning';
else if (hrs >= 00 && hrs <= 07)
greet = 'Today Morning';
document.getElementById('lblGreetings').innerHTML =
'<b>' + greet + '</b> and welcome to Encodedna.com!';
</script>
</html>
最佳答案
$(document).ready(function(){
var myDate = new Date();
var hrs = myDate.getHours();
var greet;
if (hrs > 07 && hrs <= 19)
greet = 'Today Evening';
else if (hrs >= 19 && hrs <= 24)
greet = 'Tommorow Morning';
else if (hrs >= 00 && hrs <= 07)
greet = 'Today Morning';
document.getElementById('lblGreetings').innerHTML =
'<b>' + greet + '</b> and welcome to Encodedna.com!';
});
