问题描述
希望在javascript中一起添加时间。
Looking to add time together within javascript.
我从来没有写过任何javascript,因此我正在努力进步。
I have never written any javascript, and as such am struggling with the way to progress.
我必须将 4:00
(4小时)添加到 12: 44
(当前时间)这是否可以在javascript中使用?

后来添加回答:
你提到你是一个使用JavaScript的新手,所以这里是一个使用moment.js的问题的简单工作示例 - 这个例子假设文件和moment.js在同一个文件夹中。查看关于所有格式选项的moment.js上的文档。祝你好运。
You mention your are a newbie with JavaScript so here is a simple working example of your problem using moment.js - this example assumes the file and moment.js are in the same folder. Check out the docs on the moment.js for all the formatting options. Good luck.
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Add Time</title>
<script src="moment.js"></script>
</head>
<body>
<script>
//add 4 hours to the stated time
var theFutureTime = moment().hour('12').minute('44').add(4,'hours').format("HH:mm");
console.log(theFutureTime); // prints 16:44
</script>
</body>
