-## JavaScript Handlers
-
-Instead of passing a closure, you can also pass a string to event handlers – this lets you use JavaScript (if your renderer can execute JavaScript):
-
-```rust
-{{#include ../../examples/event_javascript.rs:rsx}}
-```
-
-
-#![allow(non_snake_case)]
-use dioxus::prelude::*;
-
-fn main() {
-    dioxus_desktop::launch(App);
-}
-
-fn App(cx: Scope) -> Element {
-    cx.render(rsx! {
-        // ANCHOR: rsx
-        div {
-            onclick: "alert('hello world')",
-        }
-        // ANCHOR_END: rsx
-    })
-}
