To Load and Execute JavaScript APIs

Based on which supported programming language you are using, JavaScript code can be loaded and executed using one of the following methods:

• WEBLOAD command - AutoLISP, scripts and from the AutoCAD UI
• acjsLoadJSScript() - ObjectARX and C++
• Application.LoadJSScript() - Managed .NET

Using the acedInvoke(…) function, you can call the JavaScript functions from your C++ code. Register the functions using a global JavaScript function, the syntax is:

defun(string name, callback)

ObjectARX and C++

1. Execute JavaScript functions using this method:

   Acad::ErrorStatus acjsLoadJSScript(const ACHAR* uriOfHTML)

2. Register a callback for the JavaScript function using:

   Acad::ErrorStatus acjsDefun(const ACHAR* name, JsCallbackType callback);

   Where jsCallbackType is defined as:

   typedef JSON (*JsCallbackType)(const JSON* params)

Managed .NET

Use this information to import the .NET assembly required to execute JavaScript functions:

.NET Assembly Information

1. Execute JavaScript functions using this method:

   void LoadJSScript(System.Uri uriOfHTML)

2. Register a callback for the JavaScript function using:

   void DefunJS(String name, JsCallbackType callback)

   Where jsCallbackType is defined as:

   typedef JSON (*JsCallbackType)(const JSON* params)

AutoLISP

Execute JavaScript functions using the COMMAND function and WEBLOAD command:

(command "._webload" uriOfHtml)
