var date = new Date();
console.log(date.toLocaleDateString());
console.log(date.toDateString());
console.log(date.toLocaleString());
console.log(date.toUTCString());
console.log(date.toISOString());

字符串
从这里选择您的方法：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date

你可以做下面这些陈述

let newDate = new Date();
console.log(`${newDate.toDateString()} ${newDate.toTimeString()}`);

字符串

从上面的答案中，我们也可以用一行来做。如下所示，

var dateString = new Date().toDateString();
console.log(dateString, '\n');
var dateString = new Date().toLocaleDateString();
console.log(dateString, '\n');
var dateString = new Date().toGMTString();
console.log(dateString, '\n');

字符串

您可以将从Date.now()获得的值传递给new Date()，这将以可读格式给予时间。
举例来说：

let timestamp = Date.now();
console.log(new Date(timestamp))

字符串

new Date（）;

document.getElementById("demo").innerHTML = Date();
