func AttributeOldValue(o *Options)
func Attributes ¶
func Attributes(o *Options)
func CharacterData ¶
func CharacterData(o *Options)

Types ¶
type CallbackFunc ¶
func (CallbackFunc) HandleMutation ¶
func (f CallbackFunc) HandleMutation(r []Record, o *Observer)
type MicrotaskQueuer ¶ added in v0.11.3
type MicrotaskQueuer interface {
QueueMicrotask(clock.TaskCallback)
}
type ObserveOption ¶ added in v0.6.0
type ObserveOption = func(*Options)
type Observer ¶
type Observer struct {
Flushers MicrotaskQueuer
Callback Callback
// contains filtered or unexported fields
}
Observer implements behaviour of the MutationObserver, allowing client code to react to changes to the DOM. Mutation events are not published immediately; but before control returns to the event loop, (i.e. if an event hander generates two mutation events, an observer will not receive any events before the function has finished executing). The records can be pulled from the Observer.TakeRecords function.
Client code must first call [MutationObserver.Observe], specifying what to listen for.
The Observer must be initialized with both a MicrotaskQueuer, allowing it to register to receive notifications; and a Callback.
func NewObserver ¶
func NewObserver(f MicrotaskQueuer, cb Callback) *Observer
NewObserver creates a new observer registering with the MicrotaskQueuer f and the callback cb. NewObserver doesn't do anything except setting exported fields. The function panics if either f or cb are nil.
func (*Observer) Disconnect ¶
func (o *Observer) Disconnect()
func (*Observer) Observe ¶
Start observing for changes for a specific dom node.
Panics if the observer does not have a handler.
func (*Observer) Process ¶
func (o *Observer) Process(e dom.ChangeEvent)
func (*Observer) TakeRecords ¶
type Options ¶
type Options = dominterfaces.MutationObserverInit
type Record ¶
type Record = dominterfaces.MutationRecord
type RecordCallbackFunc ¶
type RecordCallbackFunc func([]Record)
func (RecordCallbackFunc) HandleMutation ¶
func (f RecordCallbackFunc) HandleMutation(r []Record, _ *Observer)
