Method Details

getComputedStyle

CSSComputedProperties getComputedStyle(String pseudoElt)

Gets the computed style declaration that applies to this element.

Parameters:

pseudoElt - the pseudo-element name (null if no pseudo-element).

Returns:

the computed style declaration.

getId

String getId()

Gets the id attribute of this element.

Returns:

the id attribute, or the empty string if has no ID.

getOverrideStyle

CSSStyleDeclaration getOverrideStyle(Condition pseudoElt)

Gets this element's override style declaration for a pseudo-element.

The getOverrideStyle method provides a mechanism through which a DOM author could effect immediate change to the style of an element without modifying the explicitly linked style sheets of a document or the inline style of elements.

The override style sheet comes after the author style sheet in the cascade algorithm.

Parameters:

pseudoElt - the pseudo-element condition, or null if none.

Returns:

the override style sheet for the given pseudo-element.

hasOverrideStyle

boolean hasOverrideStyle(Condition pseudoElt)

Check whether this element has an override style declaration for the given pseudo-element.

This method allows checking for override styles without the overhead of producing and retrieving one with getOverrideStyle(Condition) and checking its length.

Parameters:

pseudoElt - the pseudo-element condition, or null if none.

Returns:

true if this element has an override style declaration for pseudoElt.

getStyle

CSSStyleDeclaration getStyle()

The inline style.

Returns:

the inline style specified by the style attribute, or null if that attribute is not present.

matches

boolean matches(String selectorString,
 String pseudoElement)
         throws DOMException

Does this element (with the provided pseudo-element, if any) match the provided selector string ?

Parameters:

selectorString - the selector string.

pseudoElement - the pseudo-element, or null if none.

Returns:

true if the element would be selected by the specified selector string, false otherwise.

Throws:

DOMException - SYNTAX_ERR if there was an error parsing the selector string.

matches

boolean matches(SelectorList selist,
 Condition pseudoElement)

Does this element (with the provided pseudo-element, if any) match the provided selector list ?

Parameters:

selist - the selector list.

pseudoElement - the pseudo-element condition, or null if none.

Returns:

true if the element would be selected by at least one selector in the specified list, false otherwise.

getSelectorMatcher

SelectorMatcher getSelectorMatcher()

Gets a selector matcher associated to this element.

Returns:

a selector matcher associated to this element.

hasPresentationalHints

boolean hasPresentationalHints()

Check whether this element has non-CSS presentational hints.

A document may contain non-CSS presentational hints (like the width attribute in HTML). This method can return true only if this specific element do contain such hints, which can be exported to a style declaration by using the exportHintsToStyle(CSSStyleDeclaration) method.

Returns:

true if this element has presentational hints.

exportHintsToStyle

void exportHintsToStyle(CSSStyleDeclaration style)
                 throws DOMException

Export this element's non-CSS presentational hints (if any) to the supplied CSSStyleDeclaration.

Parameters:

style - the style declaration to export to.

Throws:

DOMException
