将日期添加到明天作为当前日期 - Javascript

Question

大家好，在此先感谢您的帮助。我在将 Javascript 日期代码从当前日期提前到明天的日期时遇到问题。我在以前的帖子中搜索过这里，但答案似乎没有用。

<SCRIPT LANGUAGE="JavaScript">
// Get today's current date.
var now = new Date();

// Array list of days.
var days = new Array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');

// Array list of months.
var months = new Array('January','February','March','April','May','June','July','August','September','October','November','December');

// Calculate the number of the current day in the week.
var date = ((now.getDate()<10) ? "0" : "")+ now.getDate();

// Calculate four digit year.
function fourdigits(number) {
    return (number < 1000) ? number + 1900 : number;
                            }

// Join it all together
today =  days[now.getDay()] + ", " +
     months[now.getMonth()] + " " +
     date + ", " +
     (fourdigits(now.getYear())) ;
</script>

+ 1 应该插入哪里才能使日期成为明天的日期？

Answer 1

now.setDate(now.getDate() + daysToAdd);

应该可以解决问题。它甚至不是 jQuery，只是 Javascript。如果您将 1 添加到字符串的末尾，请确保 now 仍被视为 Date 并且尚未在某处重新分配给其他类型。

daysToAdd 是文字还是变量应该无关紧要。两者都应该有效。

更具体地说，这应该有效：

<SCRIPT LANGUAGE="JavaScript">
// Get today's current date.
var now = new Date();
now.setDate(now.getDate() + 1);

// Array list of days.
var days = new Array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');

// Array list of months.
var months = new Array('January','February','March','April','May','June','July','August','September','October','November','December');

// Calculate the number of the current day in the week.
var date = ((now.getDate()<10) ? "0" : "")+ now.getDate();

// Calculate four digit year.
function fourdigits(number) {
    return (number < 1000) ? number + 1900 : number;
                            }

// Join it all together
today =  days[now.getDay()] + ", " +
     months[now.getMonth()] + " " +
     date + ", " +
     (fourdigits(now.getYear())) ;
</script>
