Struct percy_dom::SpecialAttributes

pub struct SpecialAttributes {
    pub dangerous_inner_html: Option<String>,
    /* private fields */
}

A specially supported attributes.

Fields

dangerous_inner_html: Option<String>

Allows setting the innerHTML of an element.

Danger

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

Implementations

impl SpecialAttributes

pub fn on_create_element_key(&self) -> Option<&Cow<'static, str>>

The key for the on create element function

pub fn set_on_create_element<Key, Func>(&mut self, key: Key, func: Func)where Key: Into<Cow<'static, str>>, Func: FnMut(Element) + 'static,

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);

pub fn maybe_call_on_create_element(&self, element: &Element)

If an on_create_element function was set, call it.

impl SpecialAttributes

pub fn on_remove_element_key(&self) -> Option<&Cow<'static, str>>

The key for the on remove element function

pub fn set_on_remove_element<Key, Func>(&mut self, key: Key, func: Func)where Key: Into<Cow<'static, str>>, Func: FnMut(Element) + 'static,

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);

pub fn maybe_call_on_remove_element(&self, element: &Element)

If an on_remove_element function was set, call it.

Trait Implementations

impl Default for SpecialAttributes

fn default() -> SpecialAttributes

Returns the “default value” for a type.

impl PartialEq<SpecialAttributes> for SpecialAttributes

fn eq(&self, other: &SpecialAttributes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
