Be sure to escape all untrusted input to avoid cross site scripting attacks.

Implementations

The key for the on create element function

Set the [SpecialAttributes.on_create_element] function.

Key

The key is used when one virtual-node is being patched over another.

If the new node’s key is different from the old node’s key, the on create element function gets called.

If the keys are the same, the function does not get called.

Examples
use wasm_bindgen::JsValue;

let mut node = VirtualNode::element("div");

// A key can be any `Into<Cow<'static, str>>`.
let key = "some-key";

let on_create_elem = move |elem: web_sys::Element| {
    assert_eq!(elem.id(), "");
};

node
    .as_velement_mut()
    .unwrap()
    .special_attributes
    .set_on_create_element(key, on_create_elem);

If an on_create_element function was set, call it.

The key for the on remove element function

Set the [SpecialAttributes.on_remove_element] function.

Key

The key is used when one virtual-node is being patched over another.

If the old node’s key is different from the new node’s key, the on remove element function gets called for the old element.

If the keys are the same, the function does not get called.

Examples
use wasm_bindgen::JsValue;

let mut node = VirtualNode::element("div");

// A key can be any `Into<Cow<'static, str>>`.
let key = "some-key";

let on_remove_elem = move |elem: web_sys::Element| {
    assert_eq!(elem.id(), "");
};

node
    .as_velement_mut()
    .unwrap()
    .special_attributes
    .set_on_remove_element(key, on_remove_elem);

If an on_remove_element function was set, call it.
