使用Moment验证MMDDYYYY格式

Question

我有以下几点。由于某些原因，moment.js无法按预期验证我的日期。当我传递字母时，它会像预期的那样失败，但是当仅使用数字时，它将始终传递。

我正在使用MMDDYYYY格式。如何使用矩来验证MMDDYYYY？谢谢

var dates = "08291975"; //passes as it should
var passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should pass ' + passed); //actual output is 'should pass true'

dates = "082919751"; //one digit too many should fail but doesnt
passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should not pass ' + passed); //actual output is 'should not pass true'

dates = "0829ssss"; //fails as expected
passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should not pass ' + passed); //actual output is 'should not pass false'

dates = "0829197"; //one digit short should fail but doesnt
passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should not pass ' + passed); //actual output is 'should not pass true'

Answer 1

您可以使用最新版本 (2.24.0) 而不是旧版本 2.2.1 获得预期输出。

这是一个实时示例：

var dates = "08291975";
var passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should pass ' + passed);

dates = "082919751"; //one extra digit
passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should not pass ' + passed);

dates = "0829ssss";
passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should not pass ' + passed);

dates = "0829197"; //one digit missing
passed = moment(dates, 'MMDDYYYY', true).isValid();
console.log('should not pass ' + passed);
