Struct yew_components::Select [−][src]
Expand description
An alternative to the HTML <select>
tag.
The display of options is handled by the ToString
implementation on their
type.
Example
#[derive(PartialEq, Clone)] enum Scene { First, Second, } impl fmt::Display for Scene { fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result { match self { Scene::First => write!(f, "{}", "First"), Scene::Second => write!(f, "{}", "Second"), } } } fn view(link: ComponentLink<Model>) -> Html { let scenes = vec![Scene::First, Scene::Second]; html! { <Select<Scene> options=scenes on_change=link.callback(|_| ()) /> } }
Properties
Only the on_change
property is mandatory. Other (optional) properties
are selected
, disabled
, options
, class
, id
, and placeholder
.

impl<T> Component for Select<T> where

[src]type Message = Msg
type Message = Msg
Messages are used to make Components dynamic and interactive. Simple
Component’s can declare their Message type to be ()
. Complex Component’s
commonly use an enum to declare multiple Message types. Read more
type Properties = Props<T>
type Properties = Props<T>
Properties are the inputs to a Component and should not mutated within a Component. They are passed to a Component using a JSX-style syntax. Read more
fn create(props: Self::Properties, link: ComponentLink<Self>) -> Self
[src]
fn create(props: Self::Properties, link: ComponentLink<Self>) -> Self
[src]Components are created with their properties as well as a ComponentLink
which
can be used to send messages and create callbacks for triggering updates. Read more
fn update(&mut self, msg: Self::Message) -> ShouldRender
[src]
fn update(&mut self, msg: Self::Message) -> ShouldRender
[src]Components handle messages in their update
method and commonly use this method
to update their state and (optionally) re-render themselves. Read more
fn change(&mut self, props: Self::Properties) -> ShouldRender
[src]
fn change(&mut self, props: Self::Properties) -> ShouldRender
[src]When the parent of a Component is re-rendered, it will either be re-created or
receive new properties in the change
lifecycle method. Component’s can choose
to re-render if the new properties are different than the previously
received properties. Most Component’s will use props with a PartialEq
impl and will be implemented like this: Read more
fn view(&self) -> Html
[src]
fn view(&self) -> Html
[src]Components define their visual layout using a JSX-style syntax through the use of the
html!
procedural macro. The full guide to using the macro can be found in Yew’s
documentation. Read more
