The JavaScript singleton is implemented only in the HTML5 export. It's used to access the browser's JavaScript context. This allows interaction with embedding pages or calling third-party JavaScript APIs.
Note: This singleton can be disabled at build-time to improve security. By default, the JavaScript singleton is enabled. Official export templates also have the JavaScript singleton enabled. See [https://docs.godotengine.org/en/3.4/development/compiling/compiling_for_web.html](Compiling for the Web) in the documentation for more information.
Static variables
Static methods
staticcreateCallback(object:Object, method:String):JavaScriptObject
Creates a reference to a script function that can be used as a callback by JavaScript. The reference must be kept until the callback happens, or it won't be called at all. See godot.JavaScriptObject for usage.
staticcreateObject(object:String, args:HaxeArray<Dynamic>):Dynamic
Creates a new JavaScript object using the new constructor. The object must a valid property of the JavaScript window. See godot.JavaScriptObject for usage.
staticdownloadBuffer(buffer:Array<UInt8>, name:String, ?mime:String):Void
Prompts the user to download a file containing the specified buffer. The file will have the given name and mime type.
Note: The browser may override the [https://en.wikipedia.org/wiki/Media_type](MIME type) provided based on the file name's extension.
Note: Browsers might block the download if godot.JavaScript.downloadBuffer is not being called from a user interaction (e.g. button click).
Note: Browsers might ask the user for permission or block the download if multiple download requests are made in a quick succession.
staticeval(code:String, ?useGlobalExecutionContext:Bool):Dynamic
Execute the string code as JavaScript code within the browser window. This is a call to the actual global JavaScript function eval().
If use_global_execution_context is true, the code will be evaluated in the global execution context. Otherwise, it is evaluated in the execution context of a function within the engine's runtime environment.
staticgetInterface(interface_:String):JavaScriptObject
Returns an interface to a JavaScript object that can be used by scripts. The interface must be a valid property of the JavaScript window. The callback must accept a single godot.Collections_Array argument, which will contain the JavaScript arguments. See godot.JavaScriptObject for usage.
