HtmlService
Servizio per restituire HTML e altri contenuti di testo da uno script.
Per motivi di sicurezza, gli script non possono restituire direttamente i contenuti a un browser. Deve invece eseguire la sanitizzazione del codice HTML in modo che non possa eseguire azioni dannose. Consulta la descrizione di
HtmlOutput
per conoscere le limitazioni relative a ciò che può essere restituito.
Proprietà
Proprietà | Tipo | Descrizione |

lato client. |
XFrameOptionsMode | XFrameOptionsMode | Un enum che rappresenta le modalità X-Frame-Options che possono essere utilizzate per gli script HtmlService lato client. |
