Example

This example uses gloo::events for adding event listeners and gloo::timers for creating timeouts. It creates a <button> element and adds a "click" event listener to it. Whenever the button is clicked, it starts a one second timeout, which sets the button's text content to "Hello from one second ago!".

use gloo::{events::EventListener, timers::callback::Timeout};
use wasm_bindgen::prelude::*;

pub struct DelayedHelloButton {
    button: web_sys::Element,
    on_click: events::EventListener,
}

impl DelayedHelloButton {
    pub fn new(document: &web_sys::Document) -> Result<DelayedHelloButton, JsValue> {
        // Create a `<button>` element.
        let button = document.create_element("button")?;

        // Listen to "click" events on the button.
        let button2 = button.clone();
        let on_click = EventListener::new(&button, "click", move |_event| {
            // After a one second timeout, update the button's text content.
            let button3 = button2.clone();
            Timeout::new(1_000, move || {
                button3.set_text_content(Some("Hello from one second ago!"));
            })
            .forget();
        });

        Ok(DelayedHelloButton { button, on_click })
    }
}
