10-13: Ensure robustness and improve readability.
To avoid a runtime error if this script executes before the Gravity Formsgformobject is available—and to follow common JavaScript conventions—consider:
- Guarding against a missing
gform.addFiltermethod.- Using dot notation (
config.showZoomSliderIfSupported) for a static property.Apply this diff:
-window.gform.addFilter( 'gpqr_scanner_config', function( config, instance, formats ) { - config['showZoomSliderIfSupported'] = true; - return config; -} ); +if ( window.gform && typeof window.gform.addFilter === 'function' ) { + window.gform.addFilter( + 'gpqr_scanner_config', + function( config, instance, formats ) { + config.showZoomSliderIfSupported = true; + return config; + } + ); +}
