Event: isTrusted property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2016.

Note: This feature is available in Web Workers.

The isTrusted read-only property of the Event interface is a boolean value that is true when the event was generated by the user agent (including via user actions and programmatic methods such as HTMLElement.focus()), and false when the event was dispatched via EventTarget.dispatchEvent(). The only exception is the click event, which initializes the isTrusted property to false in user agents.

Value

A boolean value.

Example

js
if (e.isTrusted) {
  /* The event is trusted */
} else {
  /* The event is not trusted */
}
