This option makes it possible to use he as part of HTML parsers and HTML validators. The decodeURI() function is used to decode a URI by replacing escape sequences with their respective special characters. To throw an error when such invalid HTML is encountered, set the strict option to true. This means that encode() will encode any HTML text content you feed it, even if it contains any symbols that cause parse errors. The default value for the strict option is false. encode ( 'foo © bar ≠ baz □ qux' ) // → 'foo © bar ≠ baz 𝌆 qux' // Passing an `options` object to `encode`, to explicitly disallow named references: he. In the below example, we decode an encoded URL using decodeURI() and decodeURIComponent() methods into its original form.Ĭonst encodedURLComponent = encodeURIComponent(url) ĭocument.write('Decoded URL: ' + decodedURI)Ĭonst decodedURLComponent = decodeURIComponent(encodedURLComponent) ĭocument.// Using the global default setting (defaults to `false`): he. These functions will return the decoded format of the encoded URL. The decodeURI only decodes the URI part, whereas this method decodes the URL, including the domain name.Įncoded_URI URI − It takes input for the encoded URL created by the encodeURI() function.Įncoded_URL URL − It takes input for the encoded URL created by the encodeURIComponent() function. The decoding of a URL can be done using the following methods −ĭecodeURI() function − The decodeURI() function is used to decode the URI, i.e., converting the special characters back to the original URI language.ĭecodeURIComponent() function − This function decodes the complete URL back to its original form. Lets define this short function: const decode. In the below example, we encode a URL using encodeURI() and encodeURIComponent() methods.ĭocument.write('Encoded URL: ' + encodedURI)Ĭonst encodedURLComponent=encodeURIComponent(url) ĭocument.write('Encoded URL Component: ' + encodedURLComponent) This is a one-line JavaScript code snippet that uses one of the most popular ES6 features > Arrow Function. The above functions return the encoded URL. The component encodes the domain name also.ĮncodeURIComponent(complete_url_string ) ParameterĬomplete_uri_string string − It holds the URL to be encoded.Ĭomplete_url_string string − It holds the complete URL string to be encoded. 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. Some of the characters that are not encoded are: (, / ? : & = + $ #).ĮncodeURIComponent() function − This function encodes the whole URL instead of just the URI. The decodeURIComponent() function is used to decode URL components encoding by encodeURIComponent() in JavaScript. The conversion of the special characters can be done by using the following method from JavaScript −ĮncodeURI() function − The encodeURI() function is used for encoding the complete URI, i.e., converting the special characters from the URI into browser understandable language. Many browsers automatically encode and decode the URL and the response string.Į.g., A space " " is encoded as a + or %20. The query params must also be encoded in the URL string, where the server will decode this. It is a usual task in web development, and this is generally done while making a GET request to the API with the query params. Encoding and decoding the URI and the URI components is required by the URL of any website to reach or redirect the user.
