InlineScript

in namespace DotVVM.Framework.Controls

Renders a script that is executed when the DotVVM framework is loaded.

Usage & Scenarios

Renders a script that is executed when the DotVVM framework is loaded.

Sample 1: Basic InlineScript

The content of the InlineScript control is rendered as javascript in the page.

The framework adds a global object dotvvm which can be used to access client-side features. You can use the following events fired by the framework.

init: Executed when the DotVVM scripts and all required resources are loaded and the viewmodel is applied to the page.
beforePostback: Executed before the postback is sent to the server.
afterPostback: Executed after the postback response is received from the server.
error: Executed when the postback fails due to a some error on a server.
spaNavigating: Executed when you leave some page in the SPA container.
spaNavigated: Executed when you enter some page in the SPA container.

page.dothtml

<dot:InlineScript>
  dotvvm.events.init.subscribe(function() { alert("Page loaded"); });
</dot:InlineScript>

Sample 2: Custom Error Handler

If the postback fails, you can invoke your custom code - e.g. display a message to the user.

page.dothtml
ViewModel.cs

@viewModel DotvvmWeb.Views.Docs.Controls.builtin.InlineScript.sample2.ViewModel, DotvvmWeb

<dot:Button Text="Sample Button" Click="{command: NeverEverRunThis()}" />

<!-- put inline script anywhere in the page -->
<dot:InlineScript>
	
	dotvvm.events.error.subscribe(function(args) {
		alert("Custom error handler!");
		args.handled = true;
	});
</dot:InlineScript>

using System.Threading;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.builtin.InlineScript.sample2
{
    public class ViewModel
    {
        public void NeverEverRunThis()
        {
            throw new Exception("This method was called from View Model.");
        }

    }
}
