Let params = encodeURIComponent('mango & pineapple') When accepting query parameters that may have reserved characters. When building a URL from query string parameters. When accepting an input that may have spaces. Examples const url = ''Ĭonsole.log(encodeURIComponent(url)) //https%3A%2F%2Fconst paramComponent = '?q=search'Ĭonsole.log(encodeURIComponent(paramComponent)) //"%3Fq%3Dsearch"Ĭonsole.log(url + encodeURIComponent(paramComponent)) // Here's a handy table of the difference in encoding of characters Which characters are encoded?ĮncodeURI() will not encode: will not encode: ~!*()' What is the difference between encodeURI and encodeURIComponent?ĮncodeURI and encodeURIComponent are used to encode Uniform Resource Identifiers (URIs) by replacing certain characters by one, two, three or four escape sequences representing the UTF-8 encoding of the character.ĮncodeURIComponent should be used to encode a URI Component - a string that is supposed to be part of a URL.ĮncodeURI should be used to encode a URI or an existing URL.

Sample: / is a reserved character, it is used for path component of a URI. There are reserved characters, with special meaning, and they must be encoded. The two hexadecimal digits represent the numeric value of the unsafe character. ![]() It converts the characters into a bytes using the UTF-8 encoding, and it replaces unsafe ASCII characters with a "%" character followed by two hexadecimal digits. URL encoding (Percent Encoding) is a mechanism for converting URLS into a format that can be transmitted over the Internet. URLs reference web pages (example: ), but reference also file transfer (ftp), email (mailto). ), a hostname (), and a file name (url-encode.html). URL encoding normally replaces a space with a plus (+) sign, or 20. URL encoding replaces non-ASCII characters with a '' followed by hexadecimal digits. It is specific type of Uniform Resource Identifier (URI).Ī URL contains a protocol (http, ftp. URL encoding converts non-ASCII characters into a format that can be transmitted over the Internet. Browsers request web pages by using an URL. This tool uses the javascript functions encodeURIComponent and decodeURIComponent.Ī Uniform Resource Locator (URL) is a reference to a web resource, it is a web address.
