求一个时间计算JS代码,第1张

用moment库

function calcYearAndDateDiff(startDate, endDate) {

const startDateClone = startDate.clone()

const diffYear = endDate.diff(startDateClone, 'year')

const diffDay = endDate.diff(startDateClone.add(diffYear,'years'), 'day')

return [diffYear, diffDay]

}

const startDate= moment('2000-01-01')

const today = moment()

const tomorrow = moment().add(1,'days')

const diff1 = calcYearAndDateDiff(startDate, today)

const diff2 = calcYearAndDateDiff(startDate, tomorrow)

我需要得到js实现两个数字相加的结果，可是js总是默认按照字符串处理，将两个数字连接起来。 

解决这个问题，代码如下：

<script type="text/javascript">var a = 1var b = 2var sum = parseInt(a) + parseInt(b)</script>

parseInt()是js的解析字符串的函数，返回解析后的数字。
