Implementations

impl Element

pub async fn find_element(&self, selector: impl Into<String>) -> Result<Self>

Returns the first element in the document which matches the given CSS selector.

pub async fn find_elements( &self, selector: impl Into<String>, ) -> Result<Vec<Element>>

Return all Elements in the document that match the given selector

pub async fn bounding_box(&self) -> Result<BoundingBox>

Returns the bounding box of the element (relative to the main frame)

pub async fn clickable_point(&self) -> Result<Point>

Example get the element as JSON object

    let js_fn = "function() { return this; }";
    let element_json = element.call_js_fn(js_fn, false).await?;

Execute an async javascript function

    let js_fn = "async function() { return this; }";

pub async fn json_value(&self) -> Result<Value>

Returns a JSON representation of this element.

pub async fn focus(&self) -> Result<&Self>

Calls focus on the element.

pub async fn hover(&self) -> Result<&Self>

pub async fn click(&self) -> Result<&Self>

This focuses the element by click on it

Bear in mind that if click() triggers a navigation this element may be not exist anymore.

pub async fn type_str(&self, input: impl AsRef<str>) -> Result<&Self>

    element.click().await?.type_str("this goes into the input field").await?;

pub async fn type_str_with_modifier( &self, input: impl AsRef<str>, modifiers: i64, ) -> Result<&Self>

Type the input

Example type text into an input element

    let element = page.find_element("input#searchInput").await?;
