Enum XFrameOptionsMode

An enum representing the X-Frame-Options modes that can be used for client-side HtmlService scripts. These values can be accessed from HtmlService.XFrameOptionsMode, and set by calling HtmlOutput.setXFrameOptionsMode(mode).

To call an enum, you call its parent class, name, and property. For example, HtmlService.XFrameOptionsMode.ALLOWALL.

Setting XFrameOptionsMode.ALLOWALL will let any site iframe the page, so the developer should implement their own protection against clickjacking.

If a script does not set an X-Frame-Options mode, Apps Script uses DEFAULT mode as the default.

// Serve HTML with no X-Frame-Options header (in Apps Script server-side code).
var output = HtmlService.createHtmlOutput('<b>Hello, world!</b>');
output.setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);
