let df5 = date1.diff(date2, "week"); console.log(df5); The example calculates the difference between two dayjs objects in months, days, and weeks. let df2 = date1.diff(date2, "month"); console.log(df2); The second parameter tells that the output will be in months. let df3 = ...
This function will return you the date and time in the following format: YYYY:MM:DD:HH:MM:SS. It also works in Node.js. function getDateTime() { var date = new Date(); var hour = date.getHours(); hour = (hour < 10 ? "0" : "") + hour; var min = date.getMinutes(); mi...
I have a script that prints the current date and time in JavaScript, but the DATE is always wrong. Here is the code: var currentdate = new Date(); var datetime = "Last Sync: " + currentdate.getDay() + "/" + currentdate.getMonth() + "/" + currentdate.getFullYear() + " @ ...

(1)、因为 now() 是Date()的一个静态函数,所以必须以 Date.now() 的形式来使用。 (2)、应用: 我们可以用此方法和减法运算,来计算一段js代码运行时间,从而来处理一些问题 (3)和 new Date().getTime() 相比的优点 不同申请多个Date实例对象,在(2)的应用中可以直接调该方法,而不用申请两个甚至多个Date...
