What the <thing> of <selector> asks the page.

Variants

Text

the text of SEL — the element’s text content (its own text plus its descendants’).

Fields

selector: &'a Expr<'a>

Count

the count of SEL — how many elements match.

Fields

selector: &'a Expr<'a>

Value

the value of SEL — an input’s current value.

Fields

selector: &'a Expr<'a>

Visible

SEL is visible — whether anything matches at all.

Fields

selector: &'a Expr<'a>

Hidden

SEL is hidden — the exact complement of visible, so an element is always one or the other and a test written with either word is complete.

Fields

selector: &'a Expr<'a>

Disabled

SEL is disabled — whether the match carries the disabled attribute. A PRESENCE, like the render: asking by comparing against the string "false" would call an enabled control disabled.

Fields

selector: &'a Expr<'a>

Checked

SEL is checked — a checkbox’s or radio’s LIVE state, which is a property rather than an attribute (see DomOp::SetChecked), so this follows a click.

Fields

selector: &'a Expr<'a>

Focused

SEL is focused — whether the match is the element focus is on.

Fields

selector: &'a Expr<'a>

Journal

the journal — the ACTIONS that have run, in order, as a Seq of Text.

A value rather than a bespoke assertion, so the count of, contains and item N of all work on it and the ordinary questions need no journal-specific vocabulary.

JournalShows

the journal shows A then B — did A run and B run AFTER it?

The one question a sequence operation cannot ask without an index-of. “Then” means after, not immediately after: pinning adjacency would break a test every time an unrelated turn appeared between the two it cares about.

Fields

first: Symbol

second: Symbol

Title

the title — the page title.

Url

the URL — the current path.

Implementations

impl<'a> DomQuery<'a>

pub fn selector(&self) -> Option<&'a Expr<'a>>

The selector expression, when the query has one.

pub fn noun(&self) -> &'static str

The English word this query reads as — for messages and shape printers.

Trait Implementations

impl<'a> Clone for DomQuery<'a>

fn clone(&self) -> DomQuery<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for DomQuery<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
