Types
Methods
Target.attachToTarget #
Attaches to the target with given id.
Parameters
targetId flattenOptional
booleanEnables "flat" access to the session via specifying sessionId attribute in the commands. We plan to make this the default, deprecate non-flattened mode, and eventually retire it. See crbug.com/991325.
Return object
sessionId Id assigned to the session.
Target.closeTarget #
Closes the target. If the target is a page that gets closed too.
Parameters
targetId Return object
success booleanAlways set to true. If an error occurs, the response indicates protocol error.
Target.createBrowserContext #
Creates a new empty BrowserContext. Similar to an incognito profile but you can have more than one.
Parameters
disposeOnDetachOptional
booleanIf specified, disposes this context when debugging session disconnects.
proxyServerOptional
stringProxy server, similar to the one passed to --proxy-server
proxyBypassListOptional
stringProxy bypass list, similar to the one passed to --proxy-bypass-list
originsWithUniversalNetworkAccessOptional
array[ string ]An optional list of origins to grant unlimited cross-origin access to. Parts of the URL other than those constituting origin are ignored.
Return object
browserContextId The id of the context created.
Target.createTarget #
Creates a new page.
Parameters
url stringThe initial URL the page will be navigated to. An empty string indicates about:blank.
leftOptional
integerFrame left origin in DIP (requires newWindow to be true or headless shell).
topOptional
integerFrame top origin in DIP (requires newWindow to be true or headless shell).
widthOptional
integerFrame width in DIP (requires newWindow to be true or headless shell).
heightOptional
integerFrame height in DIP (requires newWindow to be true or headless shell).
windowStateOptional
Frame window state (requires newWindow to be true or headless shell). Default is normal.
browserContextIdOptional
enableBeginFrameControlOptional
booleanWhether BeginFrames for this target will be controlled via DevTools (headless shell only, not supported on MacOS yet, false by default).
newWindowOptional
booleanWhether to create a new Window or Tab (false by default, not supported by headless shell).
backgroundOptional
booleanWhether to create the target in background or foreground (false by default, not supported by headless shell).
forTabOptional
booleanWhether to create the target of type "tab".
hiddenOptional
booleanWhether to create a hidden target. The hidden target is observable via protocol, but not
present in the tab UI strip. Cannot be created with forTab: true, newWindow: true or
background: false. The life-time of the tab is limited to the life-time of the session.
Return object
targetId The id of the page opened.
Target.detachFromTarget #
Detaches session with given id.
Parameters
sessionIdOptional
Session to detach.
targetIdOptional
Target.disposeBrowserContext #
Deletes a BrowserContext. All the belonging pages will be closed without calling their beforeunload hooks.
Parameters
browserContextId Target.getBrowserContexts #
Returns all browser contexts created with Target.createBrowserContext method.
Return object
browserContextIds array[ Browser.BrowserContextID ]An array of browser context ids.
Target.getTargets #
Retrieves a list of available targets.
Parameters
filterOptional
Only targets matching filter will be reported. If filter is not specified and target discovery is currently enabled, a filter used for target discovery is used for consistency.
Return object
targetInfos array[ TargetInfo ]The list of targets.
Target.setAutoAttach #
Controls whether to automatically attach to new targets which are considered
to be directly related to this one (for example, iframes or workers).
When turned on, attaches to all existing related targets as well. When turned off,
automatically detaches from all currently attached targets.
This also clears all targets added by autoAttachRelated from the list of targets to watch
for creation of related targets.
You might want to call this recursively for auto-attached targets to attach
to all available targets.
Parameters
autoAttach booleanWhether to auto-attach to related targets.
waitForDebuggerOnStart booleanWhether to pause new targets when attaching to them. Use Runtime.runIfWaitingForDebugger
to run paused targets.
flattenOptional
booleanEnables "flat" access to the session via specifying sessionId attribute in the commands. We plan to make this the default, deprecate non-flattened mode, and eventually retire it. See crbug.com/991325.
filterOptional
Target.setDiscoverTargets #
Controls whether to discover available targets and notify via
targetCreated/targetInfoChanged/targetDestroyed events.
Parameters
discover booleanWhether to discover available targets.
filterOptional
Only targets matching filter will be attached. If discover is false,
filter must be omitted or empty.
Events
Target.receivedMessageFromTarget #
Notifies about a new protocol message received from the session (as reported in
attachedToTarget event).
Parameters
sessionId Identifier of a session which sends a message.
message stringtargetIdOptional
Target.targetCrashed #
Issued when a target has crashed.
Parameters
targetId status stringTermination status type.
errorCode integerTermination error code.
Target.targetInfoChanged #
Issued when some information about a target has changed. This only happens between
targetCreated and targetDestroyed.
Parameters
targetInfo Types
Target.TargetInfo #
