Function use_before_unload

pub fn use_before_unload<'hook>(
    enabled: bool,
    msg: String,
) -> impl 'hook + Hook<Output = ()>

A side-effect hook that shows browser alert when user try to reload or close the page.

Example

use yew_hooks::prelude::*;

#[function_component(UseBeforeUnload)]
fn before_unload() -> Html {
    use_before_unload(true, "You have unsaved changes, are you sure?".to_string());
    
    html! {
        <>
        </>
    }
}

Note

When used in function components and hooks, this hook is equivalent to:

pub fn use_before_unload(enabled: bool, msg: String) {
    /* implementation omitted */
}
