Examples of JavaScriptSupport

org.apache.tapestry5.services.javascript.JavaScriptSupport
An environmental that acts as a replacement for the {@link RenderSupport} environmental, renaming and streamliningthe the key methods. JavaScriptSupport is very stateful, accumulating JavaScript stacks, libraries and initialization code until the end of the main page render; it then updates the rendered DOM (adding <script> tags to the <head> and <body>) before the document is streamed to the client.
JavaScriptSupport is normally accessed within a component by using the {@link Environmental} annotation on acomponent field. In addition, JavaScriptSupport may also be accessed as a service (the service {@linkplain EnvironmentalShadowBuilder internally delegates to the current environmental instance}), which is useful for service-layer objects.
The term "import" is used on many methods to indicate that the indicated resource (stack, library or stylesheet) will only be added to the final Document once.
The name is slightly a misnomer, since there's a side-line of {@linkplain #importStylesheet(Asset,StylesheetOptions) importing stylesheets} as well. @since 5.2.0
