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.
<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.
@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;
});
