I have string in the following format "30.11.2019".(我有以下格式的字符串“ 30.11.2019”。)

I need to transform it into a Date and get the short year representation (last 2 digits from year) like "19".(我需要将其转换为Date并获得像“ 19”之类的短年份表示形式（年份的最后2位数字）。) The following code doesn't work(以下代码不起作用)

var strDate = new Date("30.11.2019");
var shortYear = strDate.getFullYear();

Answer 1

Since the string you're using isn't in a format recognized by Date.parse() (more on that here ), you need to manually create that Date object.(由于您使用的字符串不是被识别的格式Date.parse() （更多的在这里 ），您需要手动创建一个Date对象。)

For example:(例如：)

 const strDate = '30.11.2019'; let [d,m,y] = strDate.split(/\D/); const date = new Date(y, --m, d); console.log(date.getFullYear()) 

You can then use Date.getFullYear() to get the year and extract the last two digits, as you need.(然后，您可以根据需要使用Date.getFullYear()获取年份并提取最后两位数字。)
