# bootstrap-input-spinner
A Bootstrap / jQuery plugin to create input spinner elements for number input.
> Note: bootstrap-input-spinner is now a ES6 module. You find the old ES5 version under es5-deprecated. The ES5 version is not maintained anymore and will be removed in the future.
**[Demo page with examples](http://shaack.com/projekte/bootstrap-input-spinner/)**
![bootstrap-input-spinner](https://shaack.com/projekte/assets/img/bootstrap-input-spinner-floatingpoint-and-i18n.png)
*Examples with floating-point and german localization*> This version is compatible with **Bootstrap 5**, but we remain a Bootstrap 4 compatible version with the branch
> bootstrap4-compatible.
> npm package versions 3.x are Bootstrap 5 compatible, versions 2.x Bootstrap 4 compatible.- **[Current, Bootstrap 5 compatible npm package](https://www.npmjs.com/package/bootstrap-input-spinner)**
- **[Bootstrap 4 compatible npm package](https://www.npmjs.com/package/bootstrap-input-spinner/v/2.1.2)**## Features
The Bootstrap InputSpinner
- is **mobile friendly** and **responsive**,
- automatically changes the value when **holding a button**,
- has **internationalized** number formatting,
- allows setting a **prefix** or a **suffix** text in the input,
- handles **`val()`** like the native element,
- **dynamically handles** changing **attribute values** like `disabled` or `class`,
- supports **templates** and **custom editors**, (*new!*)
- dispatches **`change`** and **`input`** **events on value change** like the native element and
- works **without extra css**, only Bootstrap 5 is needed.## Quickstart
### Installation
Current version, Bootstrap 5 compatible
```bash
npm install bootstrap-input-spinner
```
Bootstrap 4 compatible version
```bash
npm install [email protected]
```Or just download the GitHub repository and include `src/bootstrap-input-spinner.js`.
### HTML
Create the element in HTML. The attributes are compatible to the native `input[type="number"]` element.
```html
```
### Script
```html
import {InputSpinner} from "./src/InputSpinner.js"
const inputSpinnerElements = document.querySelectorAll("input[type='number']")
for (const inputSpinnerElement of inputSpinnerElements) {
new InputSpinner(inputSpinnerElement)
}```
That's it. **No extra css needed**, just Bootstrap 5 and jQuery. (Note: jQuery will be removed in the future)
## API Reference
### HTML Attributes
```html
```
Use these attributes to configure the behaviour
- `value` // starting value on element creation
- `min` // minimum value when stepping
- `max` // maximum value when stepping
- `step` // step size
- `inputmode` // the "inputmode" of the input, defaults to "decimal" (shows decimal keyboard on touch devices)
- `data-decimals` // shown decimal places
- `data-digit-grouping` // "false" to disable grouping (thousands separator), default is "true"
- `data-prefix` // show a prefix text in the input element
- `data-suffix` // show a suffix text in the input elementThe InputSpinner also handles the standard input attributes `required`, `disabled`, `readonly` and `placeholder`.
### Create an instance in JavaScript
Use JavaScript to create the instance as a jQuery plugin. You may provide additional configuration in an object as a
config parameter.```js
$(element).inputSpinner(config);
```#### Configuration (props)
The default configuration is
```javascript
var props = {
decrementButton: "−", // button text
incrementButton: "+", // ..
groupClass: "", // css class of the resulting input-group
buttonsClass: "btn-outline-secondary",
buttonsWidth: "2.5rem",
textAlign: "center", // alignment of the entered number
autoDelay: 500, // ms threshold before auto value change
autoInterval: 50, // speed of auto value change, set to `undefined` to disable auto-change
buttonsOnly: false, // set this `true` to disable the possibility to enter or paste the number via keyboard
keyboardStepping: true, // set this to `false` to disallow the use of the up and down arrow keys to step
locale: navigator.language, // the locale, per default detected automatically from the browser
editor: I18nEditor, // the editor (parsing and rendering of the input)
template: // the template of the input
'' +'
'${decrementButton}' +
'' +
'${incrementButton}' +
'
}
```##### decrementButton, incrementButton
HTML of the texts inside the buttons.
##### groupClass
Additional css class for the `input-group` of the rendered Bootstrap input.
##### buttonsClass
The css class of the buttons. Use it to style the increment and decrement buttons as
described [here](https://getbootstrap.com/docs/4.0/components/buttons/). Maybe `buttonsClass: btn-primary`
or `btn-success` or whatever type of buttons you want.##### buttonsWidth
The width of the increment and decrement buttons.
##### textAlign
The text alignment inside the ``.
##### autoDelay
The delay in ms after which the input automatically changes the value, when holding the increment or decrement button.
##### autoInterval
Speed of the value change when holding the button in ms. A lower value makes it faster.
##### buttonsOnly
In `buttonsOnly` mode (set `true`) no direct text input is allowed, the text-input gets the attribute `readonly`, but
the plus and minus buttons still allow to change the value.##### keyboardStepping
In `keyboardStepping` mode (set `true`) allows the use of the up/down arrow keys to increase/decrease the number by the
step.##### locale
Used to format the number in the UI. Detected automatically from the user's browser, can be set to "de", "en",… or "
de_DE", "en_GB",….##### editor (*new!*)
An Editor defines, how the input is parsed and rendered. The default editor of the spinner is the `I18nEditor`, which
renders and parses an internationalized number value. There are custom editors in `/src/custom-editors.js`. An Editor
must implement the two functions `parse(customValue)`, to parse the input to a number and `render(number)` to render the
number to the spinner input.The simplest custom Editor is the `RawEditor`, it renders just the value und parses just the value, without any changes,
like a native number input. It looks like this:```javascript
var RawEditor = function (props, element) {
this.parse = function (customFormat) {
// parse nothing
return customFormat
}
this.render = function (number) {
// render raw
return number
}
}
````props` is the configuration of the spinner and `element` is the original HTML element. You can use these values for the
configuration of the Editor, like in `I18nEditor`, which uses `props` for the language and `element` for the attributes.The `TimeEditor` renders and parses the number to time in hours and minutes, separated by a colon.
![bootstrap-input-spinner](https://shaack.com/projekte/assets/img/time-editor.png)
*Supports custom editors to parse and render everything*##### template
To modify the look completely, you can use the template parameter. There is an example about this on the
[Demo Page](http://shaack.com/projekte/bootstrap-input-spinner/).### Programmatic change and read of value
To change or read the value just use the jQuery `val()` function on the input, like this
```javascript
var currentValue = $(element).val() // read
$(element).val(newValue) // write
```> **Hint:** Reading the value in vanilla JS with `element.value` will also work, but to set the value you have to use `element.setValue(newValue)` or `$(element).val(newValue)`
### Handling attributes
The attributes
`min`, `max`, `step`, `decimals`, `placeholder`, `required`, `disabled`, `readonly` and `class`
are handled dynamically. The `class` attribute value is dynamically copied to the input element.#### Sizing
If the original elements class is set to `form-control-sm` of `form-control-lg` the class of the resulting input-group
is dynamically set to `input-group-sm` or `input-group-lg`.### Events
The InputSpinner handles `input` and `change` events like the native element.
#### Event handling with vanilla JavaScript
```javascript
element.addEventListener("change", function (event) {
newValue = this.value
})
```#### Event handling with jQuery syntax
```javascript
$(element).on("change", function (event) {
newValue = $(this).val()
})
```### Methods
Methods are passed as string values instead of the options object.
#### destroy
Removes the InputSpinner and shows the original input element.
```javascript
$(element).inputSpinner("destroy")
```## Minified version
I don't provide a minified version because I think it should be up to the using programmer to create minified versions,
with all the used script sources concatenated to one file.But, if you want it, it is easy to create your minified version with uglify: https://www.npmjs.com/package/uglify-js
Just install uglify
```bash
npm install uglify-js -g
```and then in the src-folder
```bash
uglifyjs bootstrap-input-spinner.js --compress --mangle > bootstrap-input-spinner.min.js
```Violà! :)
## Browser support
The spinner works in all modern browsers and Internet Explorer. Not tested with IE < 11.
For older browsers (IE 9 or so), that doesn't support `Intl`, when you get an error message like
**"Intl is not defined"** (See [issue #34](https://github.com/shaack/bootstrap-input-spinner/issues/34)), just use a
shim or polyfill like [Intl.js](https://github.com/andyearnshaw/Intl.js), and it works.# You may want to check out my further Bootstrap and HTML extensions
