Ergonomic extension methods for web_sys::Element.

Provides concise helpers for common DOM manipulations (attributes, classes, text/HTML content, event listeners, and child insertion/removal) on top of the lower-level web-sys API.

Required Methods

fn set_class(&self, class: &str)

Sets the class attribute, replacing any existing class list.

fn set_id(&self, id: &str)

Sets the id attribute.

fn set_text(&self, text: &str)

Replaces the element’s text content with text.

fn set_html(&self, html: &str) -> Result<(), JsValue>

Replaces the element’s inner HTML with html.

fn set_attr(&self, attr: &str, value: &str) -> Result<(), JsValue>

Sets attribute attr to value.

fn get_attr(&self, attr: &str) -> Option<String>

Returns the value of attribute attr, or None if it is absent.

fn remove_attr(&self, attr: &str) -> Result<(), JsValue>

Removes attribute attr.

fn add_class(&self, class: &str) -> Result<(), JsValue>

Adds class to the class attribute if it is not already present.

fn remove_class(&self, class: &str) -> Result<(), JsValue>

Removes class from the class attribute, dropping the attribute entirely when no classes remain.

fn toggle_class(&self, class: &str) -> Result<(), JsValue>

Adds class if absent, or removes it if present.

fn has_class(&self, class: &str) -> bool

Returns true if the class attribute contains class as a whole token.

fn on<F>(&self, event: &str, handler: F) -> Result<(), JsValue>

where F: FnMut(Event) + 'static,

Attaches handler as a listener for event.

The underlying closure is leaked so the listener remains valid for the lifetime of the element.

fn append(&self, child: &Element) -> Result<(), JsValue>

Appends child as the last child of this element.

fn prepend(&self, child: &Element) -> Result<(), JsValue>

Inserts child as the first child of this element, or appends it when the element has no children.

fn remove(&self) -> Result<(), JsValue>

Detaches this element from its parent; a no-op when it has no parent.

fn clear(&self)

Removes all child nodes of this element.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
