现在,我的代码是这样的:
var day = getDay(); //A function that gets this current day of the week as integer
var dayname = "";
if (day==0) dayname = "Su";
if (day==1) dayname = "Mo";
...
if(day==6) dayname = "Sa";
它有效,但我觉得它可能会更短,就像这样:
if (day == (0,1,2,3,4,5,6)) dayname = ("Su","Mo",...,"Sa");
有办法吗?
答案 0 :(得分:2)
var days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
var dayname = days[getDay()];
答案 1 :(得分:0)
你可以这样做:
var dayNames = ['mo', 'tu', 'we', 'th', 'fr', 'sa', 'su'];
var dayName = dayNames[getDay()];
这样就没有if
语句。如果day
从1开始并在7结束,则可以执行以下操作:
var dayName = dayNames[getDay() - 1];
答案 2 :(得分:0)
您可以使用以下方法
将数组定义为var days = ['Su', 'Mo', 'Tue', 'Thu', 'Fri', 'Sat'];
并使用索引0-6
选择特定日期。
因此,如果getDay();
返回0
,那么它会将sun
存储在dayname
var day = getDay(); //A function that gets this current day of the week as integer
var days = ['Su', 'Mo', 'Tue', 'Thu', 'Fri', 'Sat'];
var dayname = days[day];
答案 3 :(得分:0)
您需要的是查找表:
var day = getDay();
var daysByNumber = ['Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa'];
var dayName = daysByNumber[day];
答案 4 :(得分:0)
另一种方法是使用字典
var day = getDay();
dict = {0: 'Monday', 1: 'Tudesday', 2: 'Wednesday', 3: 'Thursday', 4: 'Friday', 5: 'Saturday', 6: 'Sunday'}
dayname=dict[day]
print(dayname)
