javascript - 计算年龄差异时收到警告？

Question

我在计算年龄差异时变得谨慎

这是我的代码 http://plnkr.co/edit/1wIvVISmgEqcRNnAD971?p=preview

moment.min.js:1 Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

我就是这样做的

let DOB= "09-Feb-1983"
console.log(moment(DOB, 'DD-MMM-YYYY', true).isValid())
console.log(moment().format('DD-MMM-YYYY'));
console.log(moment().diff('09-Feb-1983', 'years'))

如何删除此警告我已经指定了格式

Answer 1

您可以在将字符串传递到 diff() 函数之前将其转换为一个时刻。

尝试这样

let DOB= "09-Feb-1983"
console.log(moment(DOB, 'DD-MMM-YYYY', true).isValid())
console.log(moment().format('DD-MMM-YYYY'));
console.log(moment().diff(moment('09-Feb-1983', 'DD-MMM-YYYY'), 'years'));
