# Input Stepper: Use Cases
|
|
|
|
```js script
|
|
import { html } from '@mdjs/mdjs-preview';
|
|
import { loadDefaultFeedbackMessages } from '@lion/ui/validate-messages.js';
|
|
import '@lion/ui/define/lion-input-stepper.js';
|
|
loadDefaultFeedbackMessages();
|
|
```
|
|
|
|
## Default
|
|
|
|
When no range or step is defined, it can go infinite with default step value as `1`. You can also specify prefix content using `after` slot.
|
|
|
|
```html preview-story
|
|
<lion-input-stepper name="year">
|
|
<label slot="label">How old is the existence?</label>
|
|
<div slot="after" data-description>In Billion Years</div>
|
|
</lion-input-stepper>
|
|
```
|
|
|
|
## Attributes & Properties
|
|
|
|
### Step and Value
|
|
|
|
Use `step` attribute to specify the incrementor or decrementor difference and `value` to set the default value.
|
|
|
|
```html preview-story
|
|
<lion-input-stepper
|
|
label="Amount of oranges"
|
|
min="100"
|
|
step="100"
|
|
name="value"
|
|
value="200"
|
|
></lion-input-stepper>
|
|
```
|
|
|
|
### Range
|
|
|
|
Use `min` and `max` attribute to specify a range.
|
|
|
|
```html preview-story
|
|
<lion-input-stepper
|
|
label="Amount of oranges"
|
|
min="200"
|
|
max="500"
|
|
name="value"
|
|
step="100"
|
|
value="200"
|
|
></lion-input-stepper>
|
|
```
|
|
|
|
### Value text
|
|
|
|
Use the `.valueTextMapping` property to override the value with a text.
|
|
|
|
```js preview-story
|
|
export const valueTextMapping = () => {
|
|
const values = {
|
|
1: 'first',
|
|
2: 'second',
|
|
3: 'third',
|
|
4: 'fourth',
|
|
5: 'fifth',
|
|
6: 'sixth',
|
|
7: 'seventh',
|
|
8: 'eighth',
|
|
9: 'ninth',
|
|
10: 'tenth',
|
|
};
|
|
return html`
|
|
<lion-input-stepper
|
|
label="Order"
|
|
min="1"
|
|
max="10"
|
|
name="value"
|
|
.valueTextMapping="${values}"
|
|
></lion-input-stepper>
|
|
`;
|
|
};
|
|
```
|
|
|
|
### Formatting
|
|
|
|
Just like with the `input-amount` you can add the `formatOptions` to format the numbers to your preferences, to a different locale or adjust the amount of fractions.
|
|
|
|
```js preview-story
|
|
export const formatting = () => {
|
|
const format = { locale: 'nl-NL' };
|
|
return html`
|
|
<lion-input-stepper
|
|
label="Amount of oranges"
|
|
min="0"
|
|
max="5000"
|
|
step="100"
|
|
name="value"
|
|
.formatOptions="${format}"
|
|
.modelValue="${1200}"
|
|
></lion-input-stepper>
|
|
`;
|
|
};
|
|
```
|
|
|
|
### Aligning to step
|
|
|
|
The value is always aligned with the defined step size when using the increase or decrease buttons. The input value will be adjusted to the nearest valid step multiple. For example, with a step of `10` starting from `1`, if the user enters `55` and clicks the increase button, the value will align to `61` instead of `65` (1 > 11 > 21 > ... > 51 > 61).
|
|
|
|
```html preview-story
|
|
<lion-input-stepper
|
|
label="Amount of oranges"
|
|
min="1"
|
|
max="100"
|
|
step="10"
|
|
name="value"
|
|
alignToStep
|
|
value="55"
|
|
></lion-input-stepper>
|
|
```
