|
```js script
|
|
import { html } from '@mdjs/mdjs-preview';
|
|
import '@lion/ui/define/lion-progress-indicator.js';
|
|
import './assets/my-indeterminate-progress-spinner.js';
|
|
import './assets/my-determinate-progress-bar.js';
|
|
|
|
const changeProgress = () => {
|
|
const progressBar = document.getElementsByName('my-bar')[0];
|
|
progressBar.value = Math.floor(Math.random() * 101);
|
|
};
|
|
```
|
|
|
|
## Styled progress bar example
|
|
|
|
Add custom styles and more features by extending the `LionProgressIndicator`.
|
|
|
|
```js
|
|
export class MyDeterminateProgressBar extends LionProgressIndicator {
|
|
static get styles() {
|
|
return [
|
|
css`
|
|
:host {
|
|
display: block;
|
|
position: relative;
|
|
width: 100%;
|
|
height: 6px;
|
|
overflow: hidden;
|
|
background-color: #eee;
|
|
}
|
|
|
|
.progress__filled {
|
|
height: inherit;
|
|
background-color: green;
|
|
border-radius: inherit;
|
|
}
|
|
`,
|
|
];
|
|
}
|
|
|
|
_graphicTemplate() {
|
|
return html`
|
|
<div class="progress__filled" style="width: \${this._progressPercentage}%"></div>
|
|
`;
|
|
}
|
|
}
|
|
```
|
|
|
|
By given the progress-indicator a value it becomes determinate.
|
|
The min is automatically set to "0" and max to "100", but they can be set to your local needs.
|
|
|
|
```js preview-story
|
|
export const progressBarDemo = () => html`
|
|
<my-determinate-progress-bar
|
|
aria-label="Interest rate"
|
|
name="my-bar"
|
|
value="50"
|
|
></my-determinate-progress-bar>
|
|
<button @click="${changeProgress}">Randomize Value</button>
|
|
`;
|
|
```
|
|
|
|
## Styled progress spinner example
|
|
|
|
`LionProgressIndicator` is designed to be extended to add visuals. Implement the `_graphicTemplate()` method to set the rendered content and apply styles normally.
|
|
|
|
```js
|
|
class MyIndeterminateProgressSpinner extends LionProgressIndicator {
|
|
static get styles() {
|
|
return [
|
|
css`
|
|
.progress__icon {
|
|
display: inline-block;
|
|
width: 48px;
|
|
height: 48px;
|
|
animation: spinner-rotate 2s linear infinite;
|
|
}
|
|
|
|
.progress__filled {
|
|
animation: spinner-dash 1.35s ease-in-out infinite;
|
|
fill: none;
|
|
stroke-width: 6px;
|
|
stroke: var(--primary-color);
|
|
}
|
|
|
|
@keyframes spinner-rotate {
|
|
to {
|
|
transform: rotate(360deg);
|
|
}
|
|
}
|
|
|
|
@keyframes spinner-dash {
|
|
0% {
|
|
stroke-dasharray: 6, 122;
|
|
stroke-dashoffset: 0;
|
|
}
|
|
50% {
|
|
stroke-dasharray: 100, 28;
|
|
stroke-dashoffset: -16;
|
|
}
|
|
100% {
|
|
stroke-dasharray: 6, 122;
|
|
stroke-dashoffset: -127;
|
|
}
|
|
}
|
|
`,
|
|
];
|
|
}
|
|
|
|
_graphicTemplate() {
|
|
return html`
|
|
<svg class="progress__icon" viewBox="20 20 47 47">
|
|
<circle class="progress__filled" cx="44" cy="44" r="20.2" />
|
|
</svg>
|
|
`;
|
|
}
|
|
}
|
|
```
|
|
|
|
```js preview-story
|
|
export const main = () => html`
|
|
<my-indeterminate-progress-spinner></my-indeterminate-progress-spinner>
|
|
`;
