How to prevent focus on the controls beneath the overlay of the Blazor Spinner ?

This article explains how to prevent the focus to the control beneath the overlay of Blazor Spinner.

 You can restrict focus to the other controls beneath the overlay can be achieved by using the jsinterop by preventing the tab action handling keyDown event.

Index.razor

@using Syncfusion.Blazor.Spinner
 
<div aria-modal="true" role="dialog" tabindex="-1"> 
    <SfSpinner  @ref=_spinner @bind-Visible=@_showSpinner Label="Loading" CssClass="e-spin-overlay" ZIndex=1000 /> 
 
    <SfButton @onclick=@click>Show spinner</SfButton> 
    <SfTextBox @bind-Value=@_textInput /> 
    <p>You input is : @_textInput</p> 
</div> 
 
@code 
{ 
    SfSpinner _spinner; 
    private bool _showSpinner = false; 
    private string _textInput = string.Empty; 
 
    private async void click() 
    { 
        _showSpinner = true; 
        await jsRuntime.InvokeAsync<object>("accessDOMElement"); 
 
 
    } 
} 
 

Host.cshtml

</script>
      function accessDOMElement() {
           
        window.addEventListener('keydown', handleKey);
 
        }
    function handleKey(e) {
            
       if (e.keyCode === 9) {
           e.preventDefault();
                
            }
        }
</script>
