How to add Event Listener dynamically?

[dvorakchen]

I was try to add a event listener to body, and I found a way:

create_effect(|_| {
        document().body().unwrap().add_event_listener_with_callback(
            "click",
            &Function::new_no_args(
                "
        JS code here
        ",
            ),
        )
    });

but as you see I can only write JS code in callback function, that mean I cannot use signal.

is anybody has better idea?

To just add an event listener on the window, use one of these helpers

If you need something more specific than that, you should drop into using wasm-bindgen's Closure type to wrap Rust code as a JS function, rather than creating a function from a JS string. See their docs here
