ReactJS ColorPicker Component
The ColorPicker component for ReactJS that allows you to easily pick a color. You can configure the ColorPicker's color mode, input a color in hex or RGB format.
Prerequisites
Refer to ReactJS Getting Started before you start with this help topic.
Configuration
The ColorPicker component for ReactJS requires the following imports.
import React from 'react';import ReactDOM from 'react-dom'; import JqxColorPicker from 'jqwidgets-react/react_jqxcolorpicker.js';
Then we create our component class. Properties and methods are put as ReactJS props.
class App extends React.Component { render () { return ( <JqxColorPicker width={220} height={220} colorMode={"hue"} /> ) }}
Finally we render our class in the desired HTML element:
ReactDOM.render(<App />, document.getElementById('app'));
Events Methods & Properties
In order to bind to any event, change any property or call any method, we need a reference to the component.
For that we use the ReactJS "ref" Callback Attribute:
<JqxColorPicker ref='myColorPicker' width={220} height={220}..... />
Now, when we have a reference, we need to call the desired event/property/method.
This is done in the componentDidMount() ReactJS Component Lifecycle method.
class App extends React.Component { componentDidMount() { //your logic } render () { return ( .... ) }};
Events
The colorchange event is triggered when a new color is picked.
The following example demonstrates how to add an event listener:
componentDidMount (){ this.refs.myColorPicker.on('colorchange', (event) => { //your logic }); }
Methods & Properties
This is how you call methods & props:
//Get Methodslet color = this.refs.myColorPicker.getColor(); //Set Methodsthis.refs.myColorPicker.setColor('#bbaaff'); //Get Propertieslet height = this.refs.myColorPicker.height(); //Set Propertiesthis.refs.myColorPicker.height(400);
Every component have a method setOptions which accepts a object as an argument. This object contains component settings.
Every component also have a method getOptions which returns a object containing the component settings.
let options = this.refs.myColorPicker.getOptions();
ColorPicker Examples
Overview
The following example demonstrates how to create a ColorPicker component.
import React from 'react';import ReactDOM from 'react-dom'; import JqxColorPicker from 'jqwidgets-react/react_jqxcolorpicker.js'; class App extends React.Component { render () { return ( <JqxColorPicker width={220} height={220} /> ) }} ReactDOM.render(<App />, document.getElementById('app'));
Disabled ColorPicker
The following example demonstrates how to disable the ColorPicker component.
import React from 'react';import ReactDOM from 'react-dom'; import JqxColorPicker from 'jqwidgets-react/react_jqxcolorpicker.js'; class App extends React.Component { render () { return ( <JqxColorPicker width={600} height={100} disabled={true} /> ) }} ReactDOM.render(<App />, document.getElementById('app'));
