how does js get the timestamp of the beginning of a certain month in a certain year? Php can be realized by mktime. I wonder if there is any easy way to get js.
what I need here is to get the data of a month. First, I need to pass the start and end timestamps of a month, and the backend will judge by this.
it's best to use monent.js
let t = Date.now() - new Date('2018-4-27 10:57:00').getTime()the old brand usually uses moment.js . However, the Nuggets recently returned a dayjs , which seems to be good.
function computeTime(year, month){
return [
new Date(year, month - 1, 1).getTime(),
new Date(year, month, 0).getTime()
]
}
computeTime(2017, 2)get the time to turn the timestamp
