## Commands

### DOMDebugger.setDOMBreakpoint([DOM.NodeId](DOM.md#class-nodeid), [DOMBreakpointType](#class-dombreakpointtype), callback)

Sets breakpoint on particular operation with DOM.

### Parameters

_**nodeId ( [DOM.NodeId](DOM.md#class-nodeid) )**_<br>
> Identifier of the node to set breakpoint on.

_**type ( [DOMBreakpointType](#class-dombreakpointtype) )**_<br>
> Type of the operation to stop upon.

_**callback ( function )**_<br>

### Results

_**error ( error )**_<br>


### DOMDebugger.removeDOMBreakpoint([DOM.NodeId](DOM.md#class-nodeid), [DOMBreakpointType](#class-dombreakpointtype), callback)

Removes DOM breakpoint that was set using `setDOMBreakpoint`.

### Parameters

_**nodeId ( [DOM.NodeId](DOM.md#class-nodeid) )**_<br>
> Identifier of the node to remove breakpoint from.

_**type ( [DOMBreakpointType](#class-dombreakpointtype) )**_<br>
> Type of the breakpoint to remove.

_**callback ( function )**_<br>

### Results

_**error ( error )**_<br>


### DOMDebugger.setEventListenerBreakpoint(eventName, callback)

Sets breakpoint on particular DOM event.

### Parameters

_**eventName ( string )**_<br>
> DOM Event name to stop on (any DOM event will do).

_**callback ( function )**_<br>

### Results

_**error ( error )**_<br>


### DOMDebugger.removeEventListenerBreakpoint(eventName, callback)

Removes breakpoint on particular DOM event.

### Parameters

_**eventName ( string )**_<br>
> Event name.

_**callback ( function )**_<br>

### Results

_**error ( error )**_<br>


### DOMDebugger.setInstrumentationBreakpoint(eventName, callback)

### Results

_**error ( error )**_<br>


### DOMDebugger.setXHRBreakpoint(url, callback)

Sets breakpoint on XMLHttpRequest.

### Parameters

_**url ( string )**_<br>
> Resource URL substring. All XHRs having this substring in the URL will get stopped upon.

_**callback ( function )**_<br>

### Results

_**error ( error )**_<br>


### DOMDebugger.removeXHRBreakpoint(url, callback)

Removes breakpoint from XMLHttpRequest.

### Parameters

_**url ( string )**_<br>
