## How to use it in code
|
|
|
|
Sample code which would show a prompt with the number of days and hours between now and the selected datetime:
|
|
|
|
require("datetimeinput").input().then(result => {
|
|
E.showPrompt(`${result}\n\n${require("time_utils").formatDuration(Math.abs(result-Date.now()))}`, {buttons:{"Ok":true}}).then(function() {
|
|
load();
|
|
});
|
|
});
|
|
|
|
To set the initial value, pass a Date object named _datetime_, e.g. for today at 9:30 :
|
|
|
|
var datetime = new Date();
|
|
datetime.setHours(9, 30);
|
|
require("datetimeinput").input({datetime}).then(... |
