+## 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
+    })
+}
