Usage

To use Winsoft JSEngine 2.7 D6-Delphi 10.2 Tokyo, you need to add the unit WJSEngine to your uses clause. Then, you can create an instance of TWJSEngine class and use its methods and properties to execute jаvascript code.

For example, you can use the Run method to run a simple jаvascript expression and get the result as a variant: ` uses WJSEngine;

var Engine: TWJSEngine; Result: Variant; begin Engine := TWJSEngine.Create; try Result := Engine.Run('1 + 1'); ShowMessage(Result); // shows 2 finally Engine.Free; end; end; You can also use theRunFilemethod to run a jаvascript file from disk: uses WJSEngine;

var Engine: TWJSEngine; begin Engine := TWJSEngine.Create; try Engine.RunFile('C:\test.js'); // runs the jаvascript code in test.js file // do something with the engine finally Engine.Free; end; end; TheTWJSEngineclass also provides methods to define and access global variables and functions in jаvascript context. For example, you can use theSetGlobalVar` method to set a global variable in jаvascript:
