I have this question... I haven't found anything similar and it also seems very strange that nobody had this problem validating time with moment.js.
moment('03:55', 'HH:mm').isValid(); //true
moment('03:55jojojo', 'HH:mm').isValid(); //true
moment('03:55jojojo', 'HH:mm',true).isValid(); //true
我做错什么了吗？ 下面是一个示例:
In your question you write that moment('03:55jojojo', 'HH:mm',true).isValid(); returns true. This is incorrect. Please check your jsfiddle again.

Moment的解析器非常宽容，这可能会导致不需要的结果 行为举止.从版本2.3.0开始，您可以为最后一个指定布尔值 参数以使Moment使用严格的分析.严格的解析要求 格式和输入完全匹配.
moment('It is 2012-05-25', 'YYYY-MM-DD').isValid(); // true
moment('It is 2012-05-25', 'YYYY-MM-DD', true).isValid(); // false
moment('2012-05-25', 'YYYY-MM-DD', true).isValid(); // true
You can use both language and strictness.
moment('2012-10-14', 'YYYY-MM-DD', 'fr', true);
