React-Input-Autosize
|
|
====================
|
|
|
|
A text input for [React](http://facebook.github.io/react/index.html) that resizes itself to the current content.
|
|
|
|
|
|
## Demo & Examples
|
|
|
|
Live demo: [jedwatson.github.io/react-input-autosize](http://jedwatson.github.io/react-input-autosize/)
|
|
|
|
To run the examples locally, run:
|
|
|
|
```
|
|
npm install
|
|
npm start
|
|
```
|
|
|
|
Then open [localhost:8000](http://localhost:8000) in a browser.
|
|
|
|
|
|
## Installation
|
|
|
|
The easiest way to use React-Input-Autosize is to install it from NPM and include it in your own React build process (using Browserify, rollup, webpack, etc).
|
|
|
|
You can also use the umd build by including `dist/AutosizeInput.js` in your page. If you use this, make sure you have already included a umd React build.
|
|
|
|
```
|
|
npm install react-input-autosize --save
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
React-Input-Autosize generates an input field, wrapped in a `<div>` tag so it can detect the size of its value. Otherwise it behaves very similarly to a standard React input.
|
|
|
|
|
|
```es6
|
|
import AutosizeInput from 'react-input-autosize';
|
|
|
|
<AutosizeInput
|
|
name="form-field-name"
|
|
value={inputValue}
|
|
onChange={function(event) {
|
|
// event.target.value contains the new value
|
|
}}
|
|
/>
|
|
```
|
|
|
|
## Gotchas
|
|
|
|
### Changing the styles at runtime
|
|
The styles applied to the input are only copied when the component mounts. Because of this, subsequent changes to the stylesheet may cause size to be detected incorrectly.
|
|
|
|
To work around this, either re-mount the input (e.g. by providing a different `key` prop) or call the `copyInputStyles()` method after the styles change.
|
|
|
|
### CSP and the IE "clear" indicator
|
|
The input will automatically inject a stylesheet that hides IE/Edge's "clear" indicator, which otherwise breaks the UI. This has the downside of being incompatible with some CSP policies.
|
|
|
|
To work around this, you can pass the `injectStyles={false}` prop, but if you do this I *strongly* recommend targeting the `input` element in your own stylesheet with the following rule:
|
|
|
|
```css
|
|
input::-ms-clear {display: none;}
|
|
```
|
|
|
|
### Custom font sizes
|
|
If your input uses custom font sizes, you will need to provide the custom size to `AutosizeInput`.
|
|
|
|
```es6
|
|
<AutosizeInput
|
|
name="form-field-name"
|
|
value={inputValue}
|
|
inputStyle={{ fontSize: 36 }}
|
|
onChange={function(event) {
|
|
// event.target.value contains the new value
|
|
}}
|
|
/>
|
|
```
|
|
|
|
### Uncontrolled input
|
|
`AutosizeInput` is a [controlled input](https://facebook.github.io/react/docs/forms.html#controlled-components) and depends on the `value` prop to work as intended. It does not support being used as an uncontrolled input.
