|
|
Singleton that connects the engine with the browser's JavaScript context in Web export.
|
|
</brief_description>
|
|
<description>
|
|
The JavaScriptBridge singleton is implemented only in the Web export. It's used to access the browser's JavaScript context. This allows interaction with embedding pages or calling third-party JavaScript APIs.
|
|
[b]Note:[/b] This singleton can be disabled at build-time to improve security. By default, the JavaScriptBridge singleton is enabled. Official export templates also have the JavaScriptBridge singleton enabled. See [url=$DOCS_URL/contributing/development/compiling/compiling_for_web.html]Compiling for the Web[/url] in the documentation for more information.
