Javascript judges whether the timestamp/time date string is in the three time ranges of today, this week, and this month.
The level is limited, and the logic may be more cumbersome. If there is a better way, welcome to enlighten me.
- Determine whether it is today
Pass parameters: param is timestamp (default) / datetime string, type is timestamp / datetime
Example:
todayJudge(1669961510000)
todayJudge('2023-04-16 21:45:00', 'datetime')
todayJudge(param, type = 'timestamp') {
// 如果传入的时间戳是字符串，需要进行类型转换
if ((typeof param === 'string') && type == 'timestamp') {
param = Number(param)
}
if (type == 'datetime') {
// ios日期时间兼容
param = param.replace(/-/g, "/")
}
var currentStamp = new Date().setHours(0,0,0,0) // 当天日期，转换为时间部分为0的时间戳
var paramStamp = new Date(param).setHours(0,0,0,0) // 传入时间戳，将时间部分转换为0
// 若两个时间戳相等，说明传入的时间戳即今天
if (currentStamp == paramStamp) {
return true
}
return false
},
- Determine whether it is in this week
Pass parameters: param is timestamp (default) / datetime string, type is timestamp / datetime
Example:
weekJudge(1669961510000)
weekJudge('2023-04-16 21:45:00', 'datetime')
weekJudge(param, type = 'timestamp') {
// 如果传入的时间戳是字符串，需要进行类型转换
if ((typeof param === 'string') && type == 'timestamp') {
param = Number(param)
}
if (type == 'datetime') {
// ios日期时间兼容
param = param.replace(/-/g, "/")
}
var paramStamp = new Date(param).setHours(0,0,0,0) // 传入的时间戳，将时间部分转换为0
var currentDate = new Date() // 当天
var currentStamp = currentDate.setHours(0,0,0,0) // 当天日期，转换为时间部分为0的时间戳
var currentDay = currentDate.getDay() == 0 ? 7 : currentDate.getDay() // 当天周几，取值为（0-6），0为周日，转换为7
console.log('当天周：', currentDay, currentDate)
var dayTime = 24*60*60*1000 // 一天的毫秒数
var MondayStamp = currentStamp - (currentDay - 1) * dayTime // 本周周一初时间戳（本周一的0点）
console.log('本周周一：', new Date(MondayStamp))
var SundayStamp = currentStamp + (8 - currentDay) * dayTime // 本周周日末时间戳（下周一的0点）
console.log('下周周一：', new Date(SundayStamp))
// 当传入的时间戳满足[本周一0点，下周一0点) ，说明传入的时间在本周内
if (paramStamp >= MondayStamp && paramStamp < SundayStamp) {
return true
}
return false
},
- Determine whether it is in the current month
Pass parameters: param is timestamp (default) / datetime string, type is timestamp / datetime
Example:
monthJudge(1669961510000)
monthJudge('2023-04-16 21:45:00', 'datetime')
monthJudge(param, type = 'timestamp') {
// 如果传入的时间戳是字符串，需要进行类型转换
if ((typeof param === 'string') && type == 'timestamp') {
param = Number(param)
}
if (type == 'datetime') {
// ios日期时间兼容
param = param.replace(/-/g, "/")
}
var paramDate = new Date(param) // 传入的参数，转换为date类型
var currentDate = new Date() // 当天
// 当传入的时间戳转换为日期后，此时的年和月与当天的年和月均相等，说明处于当月
if (paramDate.getFullYear() == currentDate.getFullYear() && paramDate.getMonth() == currentDate.getMonth()) {
return true
}
return false
},
