This is a simple function you can copy/paste to do the check:const datesAreOnSameDay = (first, second) => first.getFullYear() === second.getFullYear() && first.getMonth() === second.getMonth() && first.getDate() === second.getDate();...
if (date2.getTime() === date1.getTime()) { //dates are equal } 需要注意的是,getTime()方法比较的是毫秒,所以July 10, 2018 07:22:13和July 10, 2018并不相等。不过你可以通过setHours(0, 0, 0, 0)来重置时间。 一些有用的链接 The definitive guide to JavaScript Dates 本文在 GitHub 上...
if (className !== toString.call(b)) return false; switch (className) { // Strings, numbers, regular expressions, dates, and booleans are compared by value. case '[object RegExp]': // RegExps are coerced to strings for comparison (Note: '' + /a/i === '/a/i') case '[object ...
const date1 = new Date('July 10, 2018 07:22:13')const date2 = new Date('July 10, 2018 07:22:13')if (date2.getTime() === date1.getTime()) { //dates are equal} 请记住,getTime()返回的毫秒数,因此您需要在比较中考虑时间因素。2018年7月10日07:22:13 不等于2018年7月10日。在...
Now the function checks if the passed-in date is at least 1 millisecond in the future, instead of at least 1 day in the future. We are able to compare the dates because under the hood each date stores a timestamp - the number of milliseconds elapsed between the 1st of January 1970 an...
Localized relative date/time formatting (both for past and future dates). Automatically chooses the right units (seconds, minutes, etc) to format a time interval. Examples: just now 45s 5m 15 minutes ago 3 hours ago in 2 months in 5 years ...

if(objA[i] != objB[i]){ flag = false } } return flag } //除此之外ObjectContrast也可以传第三个参数(数组)为规定,验证两个对象那些属性需要作对比, //在其for循环内,首先验证数组是否为空(如果为空则比对全部),如果不为空,再验证 i 是否存在于这个数组(数组.indexOf(i)) ...
const date = new Date('2020/07/04');let holiday;const goodFriday = new Date('2020/04/10');const independenceDay = new Date('2020/07/04');const christmas = new Date('2020/12/25');// Strict equality means two dates aren't equal unless they're// the same object reference.date =...
似乎模糊等于算子==应该相信这两个Dates具有相等的值 浏览4提问于2014-05-01得票数 5 1回答 创建我自己的deepEqual 、 我正在尝试在JavaScript中创建自己的deepEqual函数。它将比较两个值,如果它们是相同的值,则返回true。如果这两个值是对象,它将进行递归,再次调用deepEqual来比较这些对象中的值。有没有...
