Polymer wrapper around input type time with browser-dependent appearance. Basically, it allows user to use native mobile time pickers and Edge time picker, because they are looking good and provide good experience. In other cases (unsuppored type time or desktop Chrome) input will become text with ability to manually enter the value.


$ bower install se-time-input

Make sure you have the Polymer CLI installed. Then run polymer serve to serve your element locally.

<se-time-input value="12:34"></se-time-input>
var customEl = document.querySelector('se-time-input');
customEl.value; // returns String '12:34'
customEl.value = '10:00';

customEl.disabled; // returns Boolean false
customEl.disabled = true;
customEl.disabled; // returns Boolean true
  1. Placeholder

When component’s value changes from empty to non-empty placeholder should move to “upper left corner” of the component.

<se-time-input placeholder="Enter time"></se-time-input>
var customEl = document.querySelector('se-time-input');
customEl.placeholder; // returns String 'Enter time'
customEl.placeholder = 'hh:mm';
customEl.placeholder; // returns String 'hh:mm'
