ReactJS ProgressBar Component

The ProgressBar component for ReactJS represents a widget that visually indicates the progress of a lengthy operation.

Prerequisites

Refer to ReactJS Getting Started before you start with this help topic.

Configuration

The ProgressBar component for ReactJS requires the following imports.

 
import React from 'react';
import ReactDOM from 'react-dom';
 
import JqxProgressBar from 'jqwidgets-react/react_jqxprogressbar.js';
 

Then we create our component class. Properties and methods are put as ReactJS props.

  
class App extends React.Component {
  render () {
    return (
        <JqxProgressBar width={220} height={22} value={30} />
    )
  }
}
 

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:

 
<JqxProgressBar ref='myProgressBar' width={220} height={22}..... />
 

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 valueChanged event is triggered when the value is changed.

The following example demonstrates how to add an event listener:

 
componentDidMount ()
{
 
  this.refs.myProgressBar.on('valueChanged', (event) =>
  {
     //your logic
  });
 
}
 

Methods & Properties

This is how you call methods & props:

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.
