How to expire a cookie in 30 minutes using jQuery?
30 minutes is 30 * 60 * 1000 miliseconds. Add that to the current date to specify an expiration date 30 minutes in the future.
var date = new Date(); var minutes = 30; date.setTime(date.getTime() + (minutes * 60 * 1000)); $.cookie("example", "foo", { expires: date });
If you're using jQuery Cookie (https://plugins.jquery.com/cookie/), you can use decimal point or fractions.
As one day is 1, one minute would be 1 / 1440 (there's 1440 minutes in a day).
So 30 minutes is 30 / 1440 = 0.02083333.
Final code:
$.cookie("example", "foo", { expires: 30 / 1440, path: '/' });I've added path: '/' so that you don't forget that the cookie is set on the current path. If you're on /my-directory/ the cookie is only set for this very directory.
I had issues getting the above code to work within cookie.js. The following code managed to create the correct timestamp for the cookie expiration in my instance.
var inFifteenMinutes = new Date(new Date().getTime() + 15 * 60 * 1000);
