Nos permiten acceder a codigo javascript insertado en la pagina web . Una llama la funcion sin argumentos y la otra le pasa un argumento .
Unejemplo de lo que se puede conseguir con estas llamadas :
los metodos :
- Code: Select all Expand view
METHOD ScriptCallMethod(cMethod) INLINE WEBSCRIPCALLMETHOD(::hWnd,cMethod)
METHOD ScriptCallMethodArg(cMethod,cArgumento) INLINE WEBSCRIPCALLMETHODArg(::hWnd,cMethod,cArgumento)
las funciones :
- Code: Select all Expand view
HB_FUNC( WEBSCRIPCALLMETHOD )
{
WebView * Wview = ( WebView * ) hb_parnl( 1 );
NSString * string = [ [ [ NSString alloc ] initWithCString: ISCHAR( 2 ) ? hb_parc( 2 ) : "" ] autorelease ];
[[ Wview windowScriptObject] callWebScriptMethod: string withArguments:nil];
}
HB_FUNC( WEBSCRIPCALLMETHODARG )
{
WebView * Wview = ( WebView * ) hb_parnl( 1 );
NSString * string = [ [ [ NSString alloc ] initWithCString: ISCHAR( 2 ) ? hb_parc( 2 ) : "" ] autorelease ];
NSString * arg = [ [ [ NSString alloc ] initWithCString: ISCHAR( 3 ) ? hb_parc( 3 ) : "" ] autorelease ];
NSArray * args = [NSArray arrayWithObjects: arg , nil ];
[[ Wview windowScriptObject] callWebScriptMethod: string withArguments:args];
}
