Method Detail

getCharset

String getCharset()

This attribute defines the character encoding of the linked resource. The value is a space- and/or comma-delimited list of character sets as defined in RFC 2045. The default value is ISO-8859-1.

Usage note: This attribute is obsolete in HTML5 and must not be used by authors. To achieve its effect, use the Content-Type: HTTP header on the linked resource.

setCharset

void setCharset(String arg)

isDisabled

boolean isDisabled()

This attribute is used to disable a link relationship. In conjunction with scripting, this attribute could be used to turn on and off various style sheet relationships.

Note: While there is no disabled attribute in the HTML standard, there is a disabled attribute on the HTMLLinkElement DOM object.

The use of disabled as an HTML attribute is non-standard and only used by some Microsoft browsers. Do not use it. To achieve a similar effect, use one of the following techniques:

• If the disabled attribute has been added directly to the element on the page, do not include the <link> element instead;
• Set the disabled property of the DOM object via scripting.

setDisabled

void setDisabled(boolean arg)

getHref

String getHref()

This attribute specifies the URL of the linked resource. A URL might be absolute or relative.

setHref

void setHref(String arg)

getHreflang

String getHreflang()

This attribute indicates the language of the linked resource. It is purely advisory. Allowed values are determined by BCP47 for HTML5 and by RFC1766 for HTML 4. Use this attribute only if the href attribute is present.

setHreflang

void setHreflang(String arg)

getMedia

String getMedia()

This attribute specifies the media which the linked resource applies to. Its value must be a media query. This attribute is mainly useful when linking to external stylesheets by allowing the user agent to pick the best adapted one for the device it runs on.

Usage note:

• In HTML 4, this can only be a simple white-space-separated list of media description literals, i.e., media types and groups, where defined and allowed as values for this attribute, such as print, screen, aural, braille. HTML5 extended this to any kind of media queries, which are a superset of the allowed values of HTML 4.
• Browsers not supporting the CSS3 Media Queries won't necessary recognized the adequate link; do not forget to set fallback links, the restricted set of media queries defined in HTML 4.

setMedia

void setMedia(String arg)

getRel

String getRel()

This attribute names a relationship of the linked document to the current document. The attribute must be a space-separated list of the link types values. The most common use of this attribute is to specify a link to an external style sheet: the rel attribute is set to stylesheet, and the href attribute is set to the URL of an external style sheet to format the page. WebTV also supports the use of the value next for rel to preload the next page in a document series.

setRel

void setRel(String arg)

getRev

String getRev()

The value of this attribute shows the relationship of the current document to the linked document, as defined by the href attribute. The attribute thus defines the reverse relationship compared to the value of the rel attribute. Link types values for the attribute are similar to the possible values for rel .

Usage note: This attribute is obsolete in HTML5. Do not use it. To achieve its effect, use the rel attribute with the opposite link types values, e.g. made should be replaced by author. Also this attribute doesn't mean revision and must not be used with a version number, which is unfortunately the case on numerous sites.

setRev

void setRev(String arg)

getSheet

StyleSheet getSheet()

getSizes

DOMSettableTokenList getSizes()

This attribute defines the sizes of the icons for visual media contained in the resource. It must be present only if the rel contains the icon link types value. It may have the following values:

• any, meaning that the icon can be scaled to any size as it is in a vectorial format, like image/svg.
• a white-space separated list of sizes, each in the format <width in pixels>x<height in pixels> or <width in pixels>X<height in pixels>. Each of these sizes must be contained in the resource.

Usage note:

• Most icon format are only able to store one single icon; therefore most of the time the sizes contains only one entry. Among the major browsers, only the Apple's ICNS format allows the storage of multiple icons, and this format is only supported in WebKit.
• Apple's iOS does not support this attribute, hence Apple's iPhone and iPad use special, non-standard link types values to define icon to be used as Web Clip or start-up placeholder: apple-touch-icon and apple-touch-startup-icon.

setSizes

void setSizes(DOMSettableTokenList arg)

getTarget

String getTarget()

Defines the frame or window name that has the defined linking relationship or that will show the rendering of any linked resource.

setTarget

void setTarget(String arg)

getType

String getType()

This attribute is used to define the type of the content linked to. The value of the attribute should be a MIME type such as text/html, text/css, and so on. The common use of this attribute is to define the type of style sheet linked and the most common current value is text/css, which indicates a Cascading Style Sheet format.

setType

void setType(String arg)
