如何从html输入类型时间创建javascript日期对象？

Question

This question answers how to convert HH:mm:ss string into a Javascript date object. The string returned from HTML time input is not always in the HH:mm:ss format. The format varies.

The answers in the linked question will not work in-case of dynamic formats.

How to create a Javascript date object from this input value which does not have a fixed format?

Answer 1

I assume you want current date, in that case you need to get the current date and then pass the current time.

 var today = new Date(); var dd = String(today.getDate()).padStart(2, '0'); var mm = String(today.getMonth() + 1).padStart(2, '0'); //January is 0! var yyyy = today.getFullYear(); today = mm + '/' + dd + '/' + yyyy; console.log(new Date(today + " " + "13:30" /*pass your time*/)); 

Answer 2

This is an optimised version of benihamalu 's answer .

 const today = new Date(); console.log(new Date(today.toDateString() + ' ' + "13:30")); 

Answer 3

simple answer

 function TimeToDate(time) { var today = new Date(); time = new Date('1970-01-01' + ' ' + time + 'Z').getTime(); var date = today.setHours(0, 0, 0, 0); var DateTime = new Date(date + time); return DateTime; } console.log(TimeToDate("13:30:7.026"));
