How to convert dates to UNIX timestamps in MomentJS?

问题

I want to convert my date time values to Unix timestamp format (basically an epoch timestamp). For that I use:

let startDate = '2018-09-28 11:20:55';
let endDate = '2018-10-28 11:20:55';
let test1 = startDate.unix();
let test2 = endDate.unix();

However it gives me an error

ERROR TypeError: Cannot read property 'Unix' of undefined

Can anyone tell me how I can convert datetime to Unix using MomentJS?

回答1:

The issue is because you're calling unix() on plain strings. You need to instead call it on MomentJS objects. To create those, you can provide the date strings to a MomentJS constructor, like this:

let startDate = '2018-09-28 11:20:55';
let endDate = '2018-10-28 11:20:55';

let test1 = moment(startDate).unix();
let test2 = moment(endDate).unix();

console.log(test1);
console.log(test2);
