You need a timezone picker that will allow the user to pick a timezone from a list. You want it to be accessible and follow the ARIA design pattern for a select.
This is a component that controls all user interactions and state for you. It follows best practices and accessibility guidelines.
The timezones are all valid IANA time zones.
This module is distributed via npm which is bundled with node and should be installed as one of your project's dependencies:
yarn add svelte-timezone-picker
npm i --save svelte-timezone-picker
If you are going to use the svelte component, make sure you have svelte installed as well.
To use it in your Svelte app, simply import it as a component.
<script>
import TimezonePicker from 'svelte-timezone-picker';
let timezone = 'Europe/London';
function update(ev) {
console.log(ev.detail.timezone);
}
</script>
<TimezonePicker {timezone} on:update="{update}" />
To use it as a web component, add the index.js
file to your page and use it as a regular HTML element.
<!-- use the new timezone-picker element -->
<timezone-picker timezone="Europe/London"></timezone-picker>
<!-- link it as module script -->
<script type="module" src="/path/to/web/index.js"></script>
<!-- listen for the update event on the picker -->
<script>
window.addEventListener('load', () => {
const picker = document.querySelector('timezone-picker');
picker.$on('update', (event) => {
const { timezone } = event.detail;
// do stuff with the data
});
});
</script>
