Struct stdweb::web::event::ChangeEvent

pub struct ChangeEvent(_);

The ChangeEvent is fired for input, select, and textarea elements when a change to the element's value is committed by the user. Unlike the input event, the change event is not necessarily fired for each change to an element's value.

Trait Implementations

impl JsSerialize for ChangeEvent

impl TryFrom<ChangeEvent> for Reference

type Error = Void

The type returned in the event of a conversion error.

fn try_from(value: ChangeEvent) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Reference> for ChangeEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(reference: Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl<'_r> TryFrom<&'_r Reference> for ChangeEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(reference: &Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for ChangeEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl<'_r> TryFrom<&'_r Value> for ChangeEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl InstanceOf for ChangeEvent

fn instance_of(reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.

impl ReferenceType for ChangeEvent

unsafe fn from_reference_unchecked(reference: Reference) -> Self

Converts a given reference into a concrete reference-like wrapper. Doesn't do any type checking; highly unsafe to use!

impl IEvent for ChangeEvent

fn bubbles(&self) -> bool

Indicates whether this event bubbles upward through the DOM.

fn cancel_bubble(&self) -> bool

A historical alias to Event.stopPropagation().

fn set_cancel_bubble(&self, value: bool)

A historical alias to Event.stopPropagation(). Setting this to true before returning from an event handler will stop propagation of the event.

fn cancelable(&self) -> bool

Indicates whether the event is cancelable.

fn current_target(&self) -> Option<EventTarget>

A reference to the currently registered target of this event.

fn default_prevented(&self) -> bool

Indicates whether preventDefault has been called on this event.

fn event_phase(&self) -> EventPhase

Indicates which phase of event flow is currently being evaluated.

fn stop_immediate_propagation(&self)

Prevents any further listeners from being called for this event.

fn stop_propagation(&self)

Stops the propagation of this event to descendants in the DOM.

fn target(&self) -> Option<EventTarget>

Returns a reference to the target to which this event was originally registered.

fn time_stamp(&self) -> Option<f64>

Returns the time in milliseconds at which this event was created.

fn is_trusted(&self) -> bool

Indicates whether the event was generated by a user action.

fn event_type(&self) -> String

Returns a string containing the type of event. It is set when the event is constructed and is the name commonly used to refer to the specific event.

fn prevent_default(&self)

Cancels the event if it is cancelable, without stopping further propagation of the event.

impl ConcreteEvent for ChangeEvent

const EVENT_TYPE: &'static str

A string representing the event type.

impl AsRef<Reference> for ChangeEvent

fn as_ref(&self) -> &Reference

Performs the conversion.

impl From<ChangeEvent> for Reference

fn from(value: ChangeEvent) -> Self

Performs the conversion.

impl Clone for ChangeEvent

fn clone(&self) -> ChangeEvent

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for ChangeEvent

impl PartialEq<ChangeEvent> for ChangeEvent

fn eq(&self, other: &ChangeEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ChangeEvent) -> bool

This method tests for !=.

impl Debug for ChangeEvent

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
