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

MDN Reference

Methods

[iterator]()

iterator: URLSearchParamsIterator<[string, string]>;

Returns

URLSearchParamsIterator<[string, string]>


append()

append(name, value): void;

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

MDN Reference

Parameters

ParameterType
namestring
valuestring

Returns

void


delete()

delete(name, value?): void;

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

MDN Reference

Parameters

ParameterType
namestring
value?string

Returns

void


entries()

entries(): URLSearchParamsIterator<[string, string]>;

Returns an array of key, value pairs for every entry in the search params.

Returns

URLSearchParamsIterator<[string, string]>


forEach()

forEach(callbackfn, thisArg?): void;

Parameters

ParameterType
callbackfn(value, key, parent) => void
thisArg?any

Returns

void


get()

get(name): string | null;

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

MDN Reference

Parameters

ParameterType
namestring

Returns

string | null


getAll()

getAll(name): string[];

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

MDN Reference

Parameters

ParameterType
namestring

Returns

string[]


has()

has(name, value?): boolean;

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

MDN Reference

Parameters

ParameterType
namestring
value?string

Returns

boolean


keys()

keys(): URLSearchParamsIterator<string>;

Returns a list of keys in the search params.

Returns

URLSearchParamsIterator<string>


set()

set(name, value): void;

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.

MDN Reference

Parameters

ParameterType
namestring
valuestring

Returns

void


sort()

sort(): void;

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 code units 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).

MDN Reference

Returns

void


toString()

toString(): string;

Returns

string


values()

values(): URLSearchParamsIterator<string>;

Returns a list of values in the search params.

Returns

URLSearchParamsIterator<string>

Properties

size

readonly size: number;

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