yarn add @spectrum-web-components/slider
Import the side effectful registration of <sp-slider> via:
import '@spectrum-web-components/slider/sp-slider.js';
When looking to leverage the Slider base class as a type and/or for extension purposes, do so via:
import { Slider } from '@spectrum-web-components/slider';
<sp-slider label="Slider Label"></sp-slider>
<sp-slider label="Slider Label - Disabled" disabled></sp-slider>
<sp-slider label="Slider Label" variant="filled"></sp-slider>
<sp-slider
label="Slider Label - Disabled"
variant="filled"
disabled
></sp-slider>
<sp-slider label="Slider Label" variant="tick" tick-step="5"></sp-slider>
<sp-slider
label="Slider Label - Disabled"
variant="tick"
tick-step="5"
disabled
></sp-slider>
<sp-slider
label="Slider Label"
variant="tick"
tick-step="5"
tick-labels
></sp-slider>
<sp-slider
label="Slider Label - Disabled"
variant="tick"
tick-step="5"
tick-labels
disabled
></sp-slider>
<sp-slider label="Slider Label" variant="ramp"></sp-slider>
<sp-slider label="Slider Label - Disabled" variant="ramp" disabled></sp-slider>
By default, sp-slider assumes a linear scale between the min and max values.
For advanced applications, it is sometimes necessary to specify a custom
"normalization."
Normalization is the process of converting a slider to a value between 0 and 1 where 0 represents the minimum and 1 represents the maximum. See the "Three Handles Complex" example in the playground.
An <sp-slider> or <sp-slider-handle> element will process its numeric value with new Intl.NumberFormat(this.resolvedLanguage, this.formatOptions).format(this.value) in order to prepare it for visual delivery in the input. In order to customize this processing supply your own Intl.NumberFormatOptions via the formatOptions property, or format-options attribute as seen below.
this.resolvedLanguage represents the language in which the <sp-slider> or <sp-slider-handle> element is currently being delivered. By default, this value will represent the language established by the lang attribute on the root <html> element while falling back to navigator.language when that is not present. This value can be customized via a language context provided by a parent element that listens for the sp-language-context event and supplies update language settings to the callback function contained therein. Applications leveraging the <sp-theme> element to manage the visual delivery or text direcdirectiontion of their content will be also be provided a reactive context for supplying language information to its descendants.
<sp-slider
min="0"
max="1"
step="0.01"
value="0.5"
label="Slider Label"
format-options='{
"style": "percent"
}'
></sp-slider>
More advanced formatting is avialable by specifying a formatting function to
the getAriaHandleText property on an sp-slider or sp-slider-handle. Or,
for a multi-handle slider, you can format the combined value label for all
handles by passing a formatting function to the getAriaValueText property
on the parent sp-slider.
You can suppress the value label altogether using the hide-value-label
attribute.
<sp-slider label="No value label" hide-value-label></sp-slider>
Like the <input type="range"> element after which the <sp-slider> is fashioned it will dispatch input events in a stream culminating with a change event (representing the final comit of the value to the element) once the user has discontinued with the element. Both other these events can access the value of their dispatching target via event.target.value. In this way a steaming listener patters similar to the following can prove useful:
const slider = document.querySelector('sp-slider');
const endListener = ({ target }) => {
target.addEventListener('input', startListener);
target.removeEventListener('input', streamListener);
target.removeEventListener('change', endListener);
console.log(target.value);
};
const streamListener = ({ target }) => {
console.log(target.value);
};
const startListener = ({ target }) => {
target.removeEventListener('input', startListener);
target.addEventListener('input', streamListener);
target.addEventListener('change', endListener);
console.log(target.value);
};
slider.addEventListener('input', startListener);
