Removing JavaScript event listeners from parameters

Before you can remove JavaScript event listeners from parameters, Application Layer Encryption must be enabled on the URL or view.
You can remove JavaScript event listeners from parameters to protect sensitive data in parameters from being obtained by potential attackers.
Some web applications add non-malicious event listeners that improve functionality. If you choose to activate removal of event listeners on parameters, this will remove all event listeners, including non-malicious ones added by the web application. Take this into account before deciding to activate removal of event listeners.
