ReactJS Loader Component

The Loader component for ReactJS represents a component which displays an animated loading icon.

Prerequisites

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

Configuration

The Loader component for ReactJS requires the following imports.

 
import React from 'react';
import ReactDOM from 'react-dom';
 
import JqxLoader from 'jqwidgets-react/react_jqxloader.js';
 

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

  
class App extends React.Component {
  render () {
    return (
        <JqxLoader width={100} height={100} />
    )
  }
}
 

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:

 
<JqxLoader ref='myLoader' width={100} height={100}..... />
 

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 following example demonstrates how to add an event listener:

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.
