| size_t size | Size of the struct. |
| void(* runJavaScript )(const char *webTag, const ArkWeb_JavaScriptObject *javascriptObject) | Pointer to the function used to inject a JavaScript script. |
| void(* registerJavaScriptProxy )(const char *webTag, const ArkWeb_ProxyObject *proxyObject) | Pointer to the function used to register a JavaScript proxy with the window. APIs of this object can then be invoked in the window. |
| void(* deleteJavaScriptRegister )(const char *webTag, const char *objName) | Pointer to the function used to delete a specific application JavaScript object that is registered with the window using registerJavaScriptProxy. |
| void(* refresh )(const char *webTag) | Pointer to the function used to refresh the web page. |
| void(* registerAsyncJavaScriptProxy )(const char *webTag, const ArkWeb_ProxyObject *proxyObject) | Pointer to the function used to register a JavaScript proxy with the window. Asynchronous APIs of this object can then be invoked in the window. |
| ArkWeb_WebMessagePortPtr *(* createWebMessagePorts )(const char *webTag, size_t *size) | Pointer to the function used to create message ports. |
| void(* destroyWebMessagePorts )(ArkWeb_WebMessagePortPtr **ports, size_t size) | Pointer to the function used to destroy message ports. |
| ArkWeb_ErrorCode(* postWebMessage )(const char *webTag, const char *name, ArkWeb_WebMessagePortPtr *webMessagePorts, size_t size, const char *url) | Pointer to the function used to send the message port to the HTML page. |
| const char *(* getLastJavascriptProxyCallingFrameUrl )() | Pointer to the function used to obtain the URL of the last frame that calls JavaScriptProxy. This function is invoked on the thread invoked by the JavaScriptProxy. You can use registerJavaScriptProxy or JavaScriptProxy to inject a JavaScript object to a window object. You need to save the URL obtained from the invoked function. |
| void(* registerJavaScriptProxyEx )(const char *webTag, const ArkWeb_ProxyObjectWithResult *proxyObject, const char *permission) | Pointer to the function used to register a JavaScript object with the window. APIs of this object can then be invoked in the window. The synchronization method of this object can contain return values. |
