DOMDebugger Domain
DOM debugging allows setting breakpoints on particular DOM operations and events. JavaScript execution will stop on these operations as if there was a regular breakpoint set.

Methods
DOMDebugger.getEventListeners #
Returns event listeners of the given object.
parameters
- objectId
-
Runtime.RemoteObjectId
Identifier of the object to return listeners for.
- depth
-
integer
The maximum depth at which Node children should be retrieved, defaults to 1. Use -1 for the entire subtree or provide an integer larger than 0.
- pierce
-
boolean
Whether or not iframes and shadow roots should be traversed when returning the subtree (default is false). Reports listeners for all contexts if pierce is enabled.
Return Object
- listeners
-
array[ EventListener ]
Array of relevant listeners.

Removes DOM breakpoint that was set using setDOMBreakpoint.
parameters
- nodeId
-

Sets breakpoint on particular native event.
parameters
- eventName
-
string
Instrumentation name to stop on.
