Here is an example: const query = 'Danke Schön' // perofrm encode/decode const encodedStr = encodeURIComponent (query ) const decodedStr = decodeURIComponent (encodedStr ) // print valuesĬonsole. The decodeURIComponent() method is suitable for decoding query string parameters and path segments instead of a complete URL. It uses the UTF-8 encoding scheme to perform the decoding operation. The decodeURIComponent() function is used to decode URL components encoding by encodeURIComponent() in JavaScript. log (url ) // output: !leearn javascript$/ decodeURIComponent() method Here is an example: const encodedUrl = '!leearn%20javascript$/' // decode complete URL const url = decodeURI (encodedUrl ) // print decoded URLĬonsole.

Need to accept query string parameters in order to make GET requests.User has submitted values in a form that may be in a string format and need to be passed in, such as URL fields.Special characters such as &, space, ! when entered in a url need to be escaped, otherwise they may cause unpredictable situations. This means that we need to encode these characters when passing into a URL. Reserved characters that do not belong to this set must be encoded. URLs can only have certain characters from the standard 128 character ASCII set. All URLs are URIs, but not all URIs are URLs. A URL specifies a resource and how it can be accessed (the protocol). URI stands for Uniform Resource Identifier.Īnything that uniquely identifies a resource is its URI, such as id, name, or ISBN number. What is a URI and how is it different from a URL?
