}

The <a> HTML element (or anchor element), with its href attribute, creates a hyperlink to web pages, files, email addresses, locations in the same page, or anything else a URL can address.

Content within each <a> should indicate the link’s destination. If the href attribute is present, pressing the enter key while focused on the <a> element will activate it.

Fields

accesskey: Option<AttributeValueOwned>

Provides a hint for generating a keyboard shortcut for the current element. This attribute consists of a space-separated list of characters. The browser should use the first one that exists on the computer keyboard layout.

autocapitalize: Option<AttributeValueOwned>

Controls whether and how text input is automatically capitalized as it is entered/edited by the user. It can have the following values:

• off or none, no autocapitalization is applied (all letters default to lowercase)
• on or sentences, the first letter of each sentence defaults to a capital letter; all other letters default to lowercase
• words, the first letter of each word defaults to a capital letter; all other letters default to lowercase
• characters, all letters should default to uppercase

autofocus: Option<AttributeValueOwned>

Indicates that an element is to be focused on page load, or as soon as the <dialog> it is part of is displayed. This attribute is a boolean, initially false.

class: Option<AttributeValueOwned>

A space-separated list of the classes of the element. Classes allow CSS and JavaScript to select and access specific elements via the class selectors or functions like the method Document.getElementsByClassName().

contenteditable: Option<AttributeValueOwned>

An enumerated attribute indicating if the element should be editable by the user. If so, the browser modifies its widget to allow editing. The attribute must take one of the following values:

• true or the empty string, which indicates that the element must be editable;
• false, which indicates that the element must not be editable.

contextmenu: Option<AttributeValueOwned>

The id of a <menu> to use as the contextual menu for this element.

data: BTreeMap<String, AttributeValueOwned>

Forms a class of attributes, called custom data attributes, that allow proprietary information to be exchanged between the HTML and its DOM representation that may be used by scripts. All such custom data are available via the HTMLElement interface of the element the attribute is set on. The HTMLElement.dataset property gives access to them.

dir: Option<AttributeValueOwned>

An enumerated attribute indicating the directionality of the element's text. It can have the following values:

• ltr, which means left to right and is to be used for languages that are written from the left to the right (like English);
• rtl, which means right to left and is to be used for languages that are written from the right to the left (like Arabic);
• auto, which lets the user agent decide. It uses a basic algorithm as it parses the characters inside the element until it finds a character with a strong directionality, then it applies that directionality to the whole element.

download: Option<AttributeValueOwned>

Causes the browser to treat the linked URL as a download. Can be used with or without a filename value:

• Without a value, the browser will suggest a filename/extension, generated from various sources:
  • The Content-Disposition HTTP header
  • The final segment in the URL path
  • The media type (from the Content-Type header, the start of a data: URL, or Blob.type for a blob: URL)
• filename: defining a value suggests it as the filename. / and \ characters are converted to underscores (_). Filesystems may forbid other characters in filenames, so browsers will adjust the suggested name if necessary.

Note:

• download only works for same-origin URLs, or the blob: and data: schemes.
• How browsers treat downloads varies by browser, user settings, and other factors. The user may be prompted before a download starts, or the file may be saved automatically, or it may open automatically, either in an external application or in the browser itself.
• If the Content-Disposition header has different information from the download attribute, resulting behavior may differ:
  • If the header specifies a filename, it takes priority over a filename specified in the download attribute.
  • If the header specifies a disposition of inline, Chrome and Firefox prioritize the attribute and treat it as a download. Old Firefox versions (before 82) prioritize the header and will display the content inline.

draggable: Option<AttributeValueOwned>

An enumerated attribute indicating whether the element can be dragged, using the Drag and Drop API. It can have the following values:

• true, which indicates that the element may be dragged
• false, which indicates that the element may not be dragged.

enterkeyhint: Option<AttributeValueOwned>

Hints what action label (or icon) to present for the enter key on virtual keyboards.

exportparts: Option<AttributeValueOwned>

Used to transitively export shadow parts from a nested shadow tree into a containing light tree.

extra: BTreeMap<String, AttributeValueOwned>

/// Extra attributes of the element. This is a map of attribute names to their values, and the attribute names are in lowercase.

hidden: Option<AttributeValueOwned>

An enumerated attribute indicating that the element is not yet, or is no longer, relevant. For example, it can be used to hide elements of the page that can't be used until the login process has been completed. The browser won't render such elements. This attribute must not be used to hide content that could legitimately be shown.

href: Option<AttributeValueOwned>

The URL that the hyperlink points to. Links are not restricted to HTTP-based URLs — they can use any URL scheme supported by browsers:

• Sections of a page with document fragments
• Specific text portions with text fragments
• Pieces of media files with media fragments
• Telephone numbers with tel: URLs
• Email addresses with mailto: URLs
• While web browsers may not support other URL schemes, websites can with registerProtocolHandler()

hreflang: Option<AttributeValueOwned>

Hints at the human language of the linked URL. No built-in functionality. Allowed values are the same as the global lang attribute.

id: Option<AttributeValueOwned>

Defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).

inert: Option<AttributeValueOwned>

A boolean value that makes the browser disregard user input events for the element. Useful when click events are present.

inputmode: Option<AttributeValueOwned>

Provides a hint to browsers about the type of virtual keyboard configuration to use when editing this element or its contents. Used primarily on <input> elements, but is usable on any element while in contenteditable mode.

is: Option<AttributeValueOwned>

Allows you to specify that a standard HTML element should behave like a registered custom built-in element (see Using custom elements for more details).

itemid: Option<AttributeValueOwned>

The unique, global identifier of an item.

itemprop: Option<AttributeValueOwned>

Used to add properties to an item. Every HTML element may have an itemprop attribute specified, where an itemprop consists of a name and value pair.

itemref: Option<AttributeValueOwned>

Properties that are not descendants of an element with the itemscope attribute can be associated with the item using an itemref. It provides a list of element ids (not itemids) with additional properties elsewhere in the document.

itemscope: Option<AttributeValueOwned>

itemscope (usually) works along with itemtype to specify that the HTML contained in a block is about a particular item. itemscope creates the Item and defines the scope of the itemtype associated with it. itemtype is a valid URL of a vocabulary (such as schema.org) that describes the item and its properties context.

itemtype: Option<AttributeValueOwned>

Specifies the URL of the vocabulary that will be used to define itemprops (item properties) in the data structure. itemscope is used to set the scope of where in the data structure the vocabulary set by itemtype will be active.

lang: Option<AttributeValueOwned>

Helps define the language of an element: the language that non-editable elements are in, or the language that editable elements should be written in by the user. The attribute contains one "language tag" (made of hyphen-separated "language subtags") in the format defined in RFC 5646: Tags for Identifying Languages (also known as BCP 47). xml:lang has priority over it.

nonce: Option<AttributeValueOwned>

A cryptographic nonce ("number used once") which can be used by Content Security Policy to determine whether or not a given fetch will be allowed to proceed.

part: Option<AttributeValueOwned>

A space-separated list of the part names of the element. Part names allows CSS to select and style specific elements in a shadow tree via the ::part pseudo-element.

ping: Option<AttributeValueOwned>

A space-separated list of URLs. When the link is followed, the browser will send POST requests with the body PING to the URLs. Typically for tracking.

popover: Option<AttributeValueOwned>

Specifies that the element should be treated like a popover. An element with the popover attribute is hidden from the page unless it is opened by interacting with an invoking element that has popovertarget, or via showPopover().

referrerpolicy: Option<AttributeValueOwned>

How much of the referrer to send when following the link.

• no-referrer: The Referer header will not be sent.
• no-referrer-when-downgrade: The Referer header will not be sent to origins without TLS (HTTPS).
• origin: The sent referrer will be limited to the origin of the referring page: its scheme, host, and port.
• origin-when-cross-origin: The referrer sent to other origins will be limited to the scheme, the host, and the port. Navigations on the same origin will still include the path.
• same-origin: A referrer will be sent for same origin, but cross-origin requests will contain no referrer information.
• strict-origin: Only send the origin of the document as the referrer when the protocol security level stays the same (HTTPS→HTTPS), but don't send it to a less secure destination (HTTPS→HTTP).
• strict-origin-when-cross-origin (default): Send a full URL when performing a same-origin request, only send the origin when the protocol security level stays the same (HTTPS→HTTPS), and send no header to a less secure destination (HTTPS→HTTP).
• unsafe-url: The referrer will include the origin and the path (but not the fragment, password, or username). This value is unsafe, because it leaks origins and paths from TLS-protected resources to insecure origins.

rel: Option<AttributeValueOwned>

The relationship of the linked URL as space-separated link types.

role: Option<AttributeValueOwned>

Roles define the semantic meaning of content, allowing screen readers and other tools to present and support interaction with an object in a way that is consistent with user expectations of that type of object. roles are added to HTML elements using role="role_type", where role_type is the name of a role in the ARIA specification.

slot: Option<AttributeValueOwned>

Assigns a slot in a shadow DOM shadow tree to an element: An element with a slot attribute is assigned to the slot created by the <slot> element whose name attribute's value matches that slot attribute's value.

spellcheck: Option<AttributeValueOwned>

An enumerated attribute defines whether the element may be checked for spelling errors. It may have the following values:

• empty string or true, which indicates that the element should be, if possible, checked for spelling errors;
• false, which indicates that the element should not be checked for spelling errors.

style: Option<AttributeValueOwned>

Contains CSS styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the <style> element have mainly the purpose of allowing for quick styling, for example for testing purposes.

tabindex: Option<AttributeValueOwned>

An integer attribute indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position. It can take several values:

• a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation;
• 0 means that the element should be focusable and reachable via sequential keyboard navigation, but its relative order is defined by the platform convention;
• a positive value means that the element should be focusable and reachable via sequential keyboard navigation; the order in which the elements are focused is the increasing value of the tabindex. If several elements share the same tabindex, their relative order follows their relative positions in the document.

target: Option<AttributeValueOwned>

Where to display the linked URL, as the name for a browsing context (a tab, window, or <iframe>). The following keywords have special meanings for where to load the URL:

• _self: the current browsing context. (Default)
• _blank: usually a new tab, but users can configure browsers to open a new window instead.
• _parent: the parent browsing context of the current one. If no parent, behaves as _self.
• _top: the topmost browsing context (the "highest" context that's an ancestor of the current one). If no ancestors, behaves as _self.

Note: Setting target="_blank" on <a> elements implicitly provides the same rel behavior as setting rel="noopener" which does not set window.opener.

title: Option<AttributeValueOwned>

Contains a text representing advisory information related to the element it belongs to. Such information can typically, but not necessarily, be presented to the user as a tooltip.

translate: Option<AttributeValueOwned>

An enumerated attribute that is used to specify whether an element's attribute values and the values of its Text node children are to be translated when the page is localized, or whether to leave them unchanged. It can have the following values:

• empty string or yes, which indicates that the element will be translated.
• no, which indicates that the element will not be translated.

type_: Option<AttributeValueOwned>

Hints at the linked URL's format with a MIME type. No built-in functionality.

virtualkeyboardpolicy: Option<AttributeValueOwned>

An enumerated attribute used to control the on-screen virtual keyboard behavior on devices such as tablets, mobile phones, or other devices where a hardware keyboard may not be available for elements that also uses the contenteditable attribute.

• auto or an empty string, which automatically shows the virtual keyboard when the element is focused or tapped.
• manual, which decouples focus and tap on the element from the virtual keyboard's state.

Implementations

impl AOwned

pub fn tag() -> &'static str

Get the tag name of the element. This is the same as the name of the struct, in kebab-case.

pub fn set_attr(&mut self, name: &str, value: impl Into<AttributeValueOwned>)

Sets an attribute of the element. This sets the attribute of the struct. If the attribute is not a known attribute, it is added to the extra map. If the alloc feature is disabled, this function will silently fail.

Note

This only works when the attribute is lowercase.
