<script>
    var documenteditor;
    var container;
    function onCreated() {
        var documenteditorElement = document.getElementById("container");
        container = documenteditorElement.ej2_instances[0];
        documenteditor = container.documentEditor;

        ej.popups.createSpinner({

        // showSpinner() will make the spinner visible
        ej.popups.showSpinner(document.getElementById('container'));
        // Open the default document
        container.documentEditor.open(data);
        setInterval(function () {

            // hideSpinner() method used hide spinner
            ej.popups.hideSpinner(document.getElementById('container'));

        }, 5000);
    }
</script>

NOTE

In above example, we have used setInterval to hide spinner, just for demo purpose.
