browsingContext.activate command - WebDriver

Syntax

json

{
  "method": "browsingContext.activate",
  "params": {
    "context": "<contextId>"
  }
}

The params field contains:

context: A string that contains the ID of the top-level context to bring to the foreground and give focus. Context IDs are returned by commands such as browsingContext.getTree.

The result field in the response is an empty object ({}).

invalid argument: A required parameter is missing or has an invalid type. This error is also returned when the context specified by context is not a top-level context.
no such frame: No context with the given context ID is found.
unsupported operation: The browser cannot bring the context to the foreground.

The following example shows how to activate a background tab.

With a WebDriver BiDi connection and an active session, suppose you create a tab in the background using browsingContext.create with background: true, which returns the context ID of the tab. Send the following message to activate it:

json

{
  "id": 1,
  "method": "browsingContext.activate",
  "params": {
    "context": "5e5e96e8-5247-4f22-9b35-a4a2d841cbaa"
  }
}

The browser brings the tab to the foreground and responds as follows:

json

{
  "id": 1,
  "type": "success",
  "result": {}
}
