-- import "github.com/MJKWoolnough/gopherjs/mutation"
Package mutation provides a wrapper for the MutationObserver API
Usage
type Observer
type Observer struct {
*js.Object
}
Observer wraps a MutationObserver javascript object
func New
func New(f func([]*Record, *Observer)) *Observer
New creates a new wrapper around MutationObserver, which is created with the given callback
func (*Observer) Disconnect
func (m *Observer) Disconnect()
Disconnect stops the observer from receiving events
func (*Observer) Observe
func (m *Observer) Observe(n dom.Node, i ObserverInit)
Observe registers a DOM Node to receive events for
func (*Observer) TakeRecords
func (m *Observer) TakeRecords() []*Record
TakeRecords empties the record queue, returning what was in it
type ObserverInit
type ObserverInit struct {
ChildList bool
Attributes bool
CharacterData bool
Subtree bool
AttributeOldValue bool
CharacterDataOldValue bool
AttributeFilter []string
}
ObserverInit contains the options for observing a Node
type Record
type Record struct {
*js.Object
Type string `js:"type"`
AttributeName string `js:"attributeName"`
AttributeNamespace string `js:"attributeNamespace"`
OldValue string `js:"oldValue"`
}
Record is a wrapper around a MutationRecord js type
func (*Record) AddedNodes
func (r *Record) AddedNodes() []dom.Node
AddedNodes returns any nodes that were added
func (*Record) NextSibling
func (r *Record) NextSibling() dom.Node
NextSibling returns the next sibling to any added or removed nodes
func (*Record) PreviousSibling
func (r *Record) PreviousSibling() dom.Node
PreviousSibling returns the previous sibling to any added or removed nodes
func (*Record) RemovedNodes
func (r *Record) RemovedNodes() []dom.Node
RemovedNodes returns any nodes that were added
func (*Record) Target
func (r *Record) Target() dom.Node
Target returns the node associated with the record
