up.RenderResult up.RenderResult.prototype.none

Property

Whether this render pass did not result in any fragments being rendered.

There are some cases where we did not render any fragment:

• Server sent HTTP status 304 Not Modified to avoid re-rendering unchanged content.
• Server sent HTTP status 204 No Content.
• The target selector was set to ':none' by either client or server.
• The server sent an X-Up-Accept-Layer or X-Up-Dismiss-Layer header. This closes an overlay before content is rendered.
