The interface of URL is used to parse, construct, normalize, and encode URLs. The constructor of URL creates a new URL object. In order to make changes to the resolved components of the URL or to the URL. The URLSearchParams interface defines some practical methods to process URL query strings.

URI Represents a Uniform Resource Identifier (URI) reference.

XML representation refers to extensible markup language.

Interface Description

Interface name Illustrate
new URL(url: string,base?:string | URL) Create and return a URL object that references the URL specified by the absolute URL string, the relative URL string, and the basic URL string.
tostring():string The stringification method returns a USVString containing the complete URL. It is equivalent to the read-only URL.href.
toJSON():string This method returns a USVString, which contains a serialized URL version.
new URLSearchParams() The URLSearchParams() constructor has no parameters. This method creates and returns a new URLSearchParams object. The beginning'?' character will be ignored.
new URLSearchParams(string) The input parameter of URLSearchParams(string) constructor is string data type. This method creates and returns a new URLSearchParams object. The beginning'?' character will be ignored.
new URLSearchParams(obj) URLSearchParams(obj) The input parameter of the constructor is the obj data type. This method creates and returns a new URLSearchParams object. The beginning'?' character will be ignored.
new URLSearchParams(iterable) URLSearchParams(iterable) The input parameter of the constructor is the iterable data type. This method creates and returns a new URLSearchParams object. The beginning'?' character will be ignored.
has(name: string): boolean Retrieve whether the searchParams object contains name. If yes, it returns true, otherwise it returns false.
set(name: string, value string): void Retrieve whether the searchParams object contains a key-value pair whose key is name. If not, add the key-value pair, if any, modify the value corresponding to the first key in the object, and delete the remaining key-value pairs whose key is name.
sort(): void According to the Unicode code point of the key, sort all key/value pairs contained in this object and return undefined.
toString(): string According to the searchParams object, the query string applicable in the URL is returned.
keys(): iterableIterator<string> Return an iterator, which allows iterating through all the key values contained in the object.
values(): iterableIterator<string> Returns an iterator, which allows iterating over all the value values contained in the object.
append(name: string, value: string): void Insert the name, value key-value pair in the searchParams object.
delete(name: string): void Traverse the searchParams object, find all the names, and delete the corresponding key-value pairs.
get(name: string): string Retrieve the first name in the searchParams object and return the value corresponding to the name key.
getAll(name: string): string[] Retrieve all names in the searchParams object and return all the values corresponding to the name key.
entries(): iterableIterator<[string, string]> Returns an iterator that allows iterating through all key/value pairs contained in the searchParams object.
forEach(): void Through the callback function to traverse the key-value pairs on the URLSearchParams instance object.
urlSearchParams[Symbol.iterator]() Returns an ES6 iterator for each name-value pair in the query string. Each item of the iterator is a JavaScript array.
URI​(String str) Construct the URI by parsing the given input parameter (String str). This constructor parses the given string strictly in accordance with the grammatical provisions in RFC 2396 Appendix A.
getScheme​() Return the scheme component of this URI, or null if the scheme is not defined.
getAuthority​() Returns the decoded authority component of this URI, or null if authority is not defined. The string returned by this method is the same as the string returned by the getRawAuthority method, except that all escaped octet sequences are decoded.
getSchemeSpecificPart​() Returns the decoding scheme-specific part of this URI. The string returned by this method is the same as the string returned by the getRawSchemeSpecificPart method, except that all escaped octet sequences are decoded.
getUserInfo​() Returns the decoded userinfo component of this URI. The userinfo component of the URI (if defined) only contains characters in unreserved, punctuation, escape, and other categories.
getHost​() Return the host component of this URI, or null if host is not defined.
getPort​() Return the port of this URI, or -1 if the port is not defined. The port component of the URI (if defined) is a non-negative integer.
getQuery​() Returns the decoded query component of this URI, or null if the query is not defined. The string returned by this method is the same as the string returned by the getRawQuery method, except that all escaped octet sequences are decoded.
getFragment​() Returns the decoded fragment component of this URI, or null if the fragment is not defined. The string returned by this method is the same as the string returned by the getRawFragment method, except that all escaped octet sequences are decoded.
getPath​() Returns the decoded path component of this URI, or null if path is not defined. The string returned by this method is the same as the string returned by the getRawPath method, except that all escaped octet sequences are decoded.
equals(Object ob) Test whether this URI is equal to another object. If the given object is not a URI, this method immediately returns false.
normalize​() Normalize the path of this URI. If this URI is opaque, or its path is already in normal form, then this URI is returned. Otherwise, a new URI identical to this URI will be constructed.
isAbsolute​() Determine whether this URI is absolute. If and only if it has a scheme component, the URI is absolute and the return value is true, otherwise the return value is false.
toString() Return the content of this URI as a string.
ConvertXml() The constructor used to construct the convertxml class object. This constructor does not need to pass in parameters.
convert(String xml, Object options) Returns a JavaScript object that converts an XML string as required by the option.

Instructions for use

The usage of each interface is as follows:
