Interface DOMDebugger

public interface DOMDebugger
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.

  • Method Details

    • getEventListeners

      List<EventListener> getEventListeners(String objectId)
      Returns event listeners of the given object.
      Parameters:
      objectId - Identifier of the object to return listeners for.
      Returns:
      Array of relevant listeners.

    • getEventListeners

      List<EventListener> getEventListeners(String objectId, Integer depth, Boolean pierce)
      Returns event listeners of the given object.
      Parameters:
      objectId - Identifier of the object to return listeners for.
      depth - 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 - 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.
      Returns:
      Array of relevant listeners.

    • removeDOMBreakpoint

      void removeDOMBreakpoint(Integer nodeId, DOMBreakpointType type)
      Removes DOM breakpoint that was set using setDOMBreakpoint.
      Parameters:
      nodeId - Identifier of the node to remove breakpoint from.
      type - Type of the breakpoint to remove.

    • removeEventListenerBreakpoint

      void removeEventListenerBreakpoint(String eventName)
      Removes breakpoint on particular DOM event.
      Parameters:
      eventName - Event name.

    • removeEventListenerBreakpoint

      void removeEventListenerBreakpoint(String eventName, String targetName)
      Removes breakpoint on particular DOM event.
      Parameters:
      eventName - Event name.
      targetName - EventTarget interface name.

    • removeInstrumentationBreakpoint

      void removeInstrumentationBreakpoint(String eventName)
      Removes breakpoint on particular native event.
      Parameters:
      eventName - Instrumentation name to stop on.

    • removeXHRBreakpoint

      void removeXHRBreakpoint(String url)
      Removes breakpoint from XMLHttpRequest.
      Parameters:
      url - Resource URL substring.

    • setBreakOnCSPViolation

      void setBreakOnCSPViolation(CSPViolationType violationTypes)
      Sets breakpoint on particular CSP violations.
      Parameters:
      violationTypes - CSP Violations to stop upon.

    • setDOMBreakpoint

      void setDOMBreakpoint(Integer nodeId, DOMBreakpointType type)
      Sets breakpoint on particular operation with DOM.
      Parameters:
      nodeId - Identifier of the node to set breakpoint on.
      type - Type of the operation to stop upon.

    • setEventListenerBreakpoint

      void setEventListenerBreakpoint(String eventName)
      Sets breakpoint on particular DOM event.
      Parameters:
      eventName - DOM Event name to stop on (any DOM event will do).

    • setEventListenerBreakpoint

      void setEventListenerBreakpoint(String eventName, String targetName)
      Sets breakpoint on particular DOM event.
      Parameters:
      eventName - DOM Event name to stop on (any DOM event will do).
      targetName - EventTarget interface name to stop on. If equal to "*" or not provided, will stop on any EventTarget.

    • setInstrumentationBreakpoint

      void setInstrumentationBreakpoint(String eventName)
      Sets breakpoint on particular native event.
      Parameters:
      eventName - Instrumentation name to stop on.

    • setXHRBreakpoint

      void setXHRBreakpoint(String url)
      Sets breakpoint on XMLHttpRequest.
      Parameters:
      url - Resource URL substring. All XHRs having this substring in the URL will get stopped upon.
