diff
函数
default()
default(
date,input,unit,asFloat?):number
定义于: src/diff.ts:60
Calculates the difference between two dates in specified time units. 计算两个日期之间的指定时间单位差异。
参数
date
Date
The first date. (第一个日期。)
input
The second date. (第二个日期。)
unit
The unit of time to calculate the difference in (e.g., 'year', 'month', 'day', 'hour', 'minute', 'second', 'millisecond'). (要计算差异的时间单位，例如 'year'、'month'、'day'、'hour'、'minute'、'second'、'millisecond'。)
asFloat?
boolean
Whether to return the difference as a floating-point number. (是否以浮点数形式返回差异。)
返回
number
The difference between the two dates in the specified time units. (两个日期之间的指定时间单位差异。)
示例
ts
// Calculating the difference in years (计算年份差异)
const date1 = new Date('2023-01-01');
const date2 = new Date('2024-01-01');
const yearsDiff = diff(date1, date2, 'year');
console.log(yearsDiff); // Outputs: 1 (输出: 1)
// Calculating the difference in months (计算月份差异)
const monthsDiff = diff(date1, date2, 'month');
console.log(monthsDiff); // Outputs: 12 (输出: 12)
// Calculating the difference in days (计算天数差异)
const daysDiff = diff(date1, date2, 'day');
console.log(daysDiff); // Outputs: 365 (输出: 365)
// Calculating the difference in hours (计算小时差异)
const hoursDiff = diff(date1, date2, 'hour');
console.log(hoursDiff); // Outputs: 8760 (输出: 8760)
// Calculating the difference in minutes (计算分钟差异)
const minutesDiff = diff(date1, date2, 'minute');
console.log(minutesDiff); // Outputs: 525600 (输出: 525600)
// Calculating the difference in seconds (计算秒数差异)
const secondsDiff = diff(date1, date2, 'second');
console.log(secondsDiff); // Outputs: 31536000 (输出: 31536000)
// Calculating the difference in milliseconds (计算毫秒差异)
const msDiff = diff(date1, date2, 'millisecond');
console.log(msDiff); // Outputs: 31536000000 (输出: 31536000000)
