Setup for local environment

Refer to the following steps to set up your local environment.

Step 1: Create a root folder named my-app for your application.

Step 2: Create a my-app/resources folder to store local scripts and styles files.

Step 3: Open Visual Studio Code and create my-app/index.js and my-app/index.html files to initialize the Essential^® JS 2 Spinner control.

Create Spinner

Initialize the Spinner using the createSpinner method and show/hide the spinner using the showSpinner and hideSpinner methods. Set the target to render the spinner based on a specific element:

  createSpinner({
    target: document.getElementById('container')
  });

Show and hide this spinner by using showSpinner and hideSpinner methods for loading in your page.

Create the Spinner globally

The Spinner can be render globally in a page using public exported functions of the ej.popups.

index.js
index.html
//createSpinner() method is used to create spinner

ej.popups.createSpinner({

  // Specify the target for the spinner to show

  target: document.getElementById('container')

});

//showSpinner() will make the spinner visible

ej.popups.showSpinner(document.getElementById('container'));

setInterval(function () {

  //hideSpinner() method used hide spinner 

  ej.popups.hideSpinner(document.getElementById('container'))

}, 100000);
