日复一日地改变 js html

Question

我有一个代码：

var dayNames = new Array("wednesday", "wednesday", "thursday", "friday",
  "wednesday", "thursday", "friday");
var now = new Date();
document.write("Buy nowe, you geti it on " + dayNames[now.getDay()]);

<a id="orderBy"></a>

我想在下午 2 点之后更改下一天。有人可以帮我吗？

Answer 1

像这样 - 我假设周五之后的任何一天 14:00 和周三之前的 14:00 意味着周三交货

const dayNames = ["wednesday", "wednesday", "thursday", "friday", "wednesday", "thursday", "friday"];
let now = new Date();
if (now.getHours() >= 14) now.setDate(now.getDate()+1)
document.write("Buy nowe, you geti it on " + dayNames[now.getDay()]);

<a id="orderBy"></a>

Answer 2

试试这个

var now = new Date();
var day = now.getDay();
if (now.getHours() >= 14){
    day += 1;
}

document.write("Buy nowe, you geti it on " + dayNames[day]);

Answer 3

您可以将时间设置为从现在起 14 小时。因此，如果是下午 2 点或之后，将被视为 12:00am 第二天及之后。

let shippingTime = new Date();
shippingTime.setHours(shippingTime.getHours() + 14);

document.write("Buy now, you get it on " + dayNames[shippingTime.getDay()]);

<a id="orderBy"></a>
