使用JavaScript获取当前时间 (Getting current time in JavaScript)
To get the current time in JavaScript, we need to use three library functions of Date class,
要获取JavaScript中的当前时间 ，我们需要使用Date类的三个库函数，
Date getHours() Method – It returns current hours
Date getHours()方法 –返回当前时间
Date getMinutes() Method – It returns current minutes
Date getMinutes()方法 –返回当前分钟
Date getSeconds() Method – It returns current seconds
Date getSeconds()方法 –返回当前秒数
Note: To call these functions, we need to create an object to the Date class using Date class constructor.
注意：要调用这些函数，我们需要使用Date类的构造函数为Date类创建一个对象。
Examples:
例子：
Date class constructor:
var dt = new Date();
Function calls:
dt.getHours();
dt.getMinues();
dt.getSeconds();
Output:
20
12
35
