URL

The hash property of the URL interface is a string containing a "#" followed by the fragment identifier of the URL. If the URL does not have a fragment identifier, this property contains an empty string, "".

The host property of the URL interface is a string containing the host, which is the URL.hostname, and then, if the port of the URL is nonempty, a ":", followed by the URL.port of the URL. If the URL does not have a hostname, this property contains an empty string, "".

The hostname property of the URL interface is a string containing either the domain name or IP address of the URL. If the URL does not have a hostname, this property contains an empty string, "". IPv4 and IPv6 addresses are normalized, such as stripping leading zeros, and domain names are converted to IDN.

The href property of the URL interface is a string containing the whole URL.

The origin read-only property of the URL interface returns a string containing the Unicode serialization of the origin of the represented URL.

The URL.parse() static method of the URL interface returns a newly created URL object representing the URL defined by the parameters.

The password property of the URL interface is a string containing the password component of the URL. If the URL does not have a password, this property contains an empty string, "".

The pathname property of the URL interface represents a location in a hierarchical structure. It is a string constructed from a list of path segments, each of which is prefixed by a / character.

The port property of the URL interface is a string containing the port number of the URL. If the port is the default for the protocol (80 for ws: and http:, 443 for wss: and https:, and 21 for ftp:), this property contains an empty string, "".

The protocol property of the URL interface is a string containing the protocol or scheme of the URL, including the final ":".

The search property of the URL interface is a search string, also called a query string, that is a string containing a "?" followed by the parameters of the URL. If the URL does not have a search query, this property contains an empty string, "".

The searchParams read-only property of the URL interface returns a URLSearchParams object allowing access to the GET decoded query arguments contained in the URL.

The toJSON() method of the URL interface returns a string containing a serialized version of the URL, although in practice it seems to have the same effect as URL.toString().

The toString() method of the URL interface returns a string containing the whole URL. It is effectively a read-only version of URL.href.

The URL() constructor returns a newly created URL object representing the URL defined by the parameters.

The username property of the URL interface is a string containing the username component of the URL. If the URL does not have a username, this property contains an empty string, "".

The URLSearchParams interface defines utility methods to work with the query string of a URL.

[Symbol.iterator]

The append() method of the URLSearchParams interface appends a specified key/value pair as a new search parameter.

The delete() method of the URLSearchParams interface deletes specified parameters and their associated value(s) from the list of all search parameters.

`value` parameter

The entries() method of the URLSearchParams interface returns an Iteration_protocols allowing iteration through all key/value pairs contained in this object. The iterator returns key/value pairs in the same order as they appear in the query string. The key and value of each pair are strings.

The forEach() method of the URLSearchParams interface allows iteration through all values contained in this object via a callback function.

The get() method of the URLSearchParams interface returns the first value associated to the given search parameter.

The getAll() method of the URLSearchParams interface returns all the values associated with a given search parameter as an array.

The has() method of the URLSearchParams interface returns a boolean value that indicates whether the specified parameter is in the search parameters.

`value` parameter

The keys() method of the URLSearchParams interface returns an Iteration_protocols allowing iteration through all keys contained in this object. The keys are strings.

The set() method of the URLSearchParams interface sets the value associated with a given search parameter to the given value. If there were several matching values, this method deletes the others. If the search parameter doesn't exist, this method creates it.

The size read-only property of the URLSearchParams interface indicates the total number of search parameter entries.

The URLSearchParams.sort() method sorts all key/value pairs contained in this object in place and returns undefined. Key/value pairs are sorted by the values of the UTF-16 of the keys. This method uses a stable sorting algorithm (i.e., the relative order between key/value pairs with equal keys will be preserved).

The toString() method of the URLSearchParams interface returns a query string suitable for use in a URL.

The URLSearchParams() constructor creates and returns a new URLSearchParams object.

record for `init` object

sequence for `init` object

`USVString` for `init` object

The values() method of the URLsearchParams interface returns an Iteration_protocols allowing iteration through all values contained in this object. The values are strings.
