** used for the encodeURIComponent function */ The encodeURIComponent () function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two surrogate characters). So here is my class: import java.io.UnsupportedEncodingException I came up with my own version of the encodeURIComponent, because the posted solution has one problem, if there was a + present in the String, which should be encoded, it will converted to a space. * Private constructor to prevent this class from being instantiated. Public static String encodeURIComponent(String s) This decodeURIComponent() function decodes a Uniform Resource Identifier (URI) means it will remove all the escape sequences in the provided URI which was.

* with JavaScript's encodeURIComponent function. Learn how to use Node.js built-in modules and JavaScript functions to encode or decode a URL string in a Node.js application. * Encodes the passed String as UTF-8 using an algorithm that's compatible Public static String decodeURIComponent(String s) * s The UTF-8 encoded String to be decoded Syntax decodeURIComponent (encodedURI) Parameters encodedURI: An encoded component of a Uniform Resource Identifier. * JavaScript's decodeURIComponent function. The decodeURIComponent function is used to decode a Uniform Resource Identifier (URI) component previously created by encodeURIComponent. * Decodes the passed UTF-8 String using an algorithm that's compatible with The decodeURI only decodes the URI part, whereas this method decodes the URL, including the domain name. * Utility class for JavaScript compatible UTF-8 encoding and decoding. decodeURIComponent () function This function decodes the complete URL back to its original form. This is the class I came up with in the end: import java.io.UnsupportedEncodingException This program outputs: URLEncoder.encode returns %22A%22+B+%C2%B1+%22Ĭlose, but no cigar! What is the best way of encoding a UTF-8 string using Java so that it produces the same output as JavaScript's encodeURIComponent?ĮDIT: I'm using Java 1.4 moving to Java 5 shortly. Public static void main(String args) throws UnsupportedEncodingException AF wasn't produced by encodeURIComponent but something like escape, so it can be decoded by unescape. Here's my little test Java program: import java.io.UnsupportedEncodingException Solution 1 AF is not a character on his own but part of Unicode sequence ( MACRON - C2AF ).

If I enter the following JavaScript statement in Firebug: encodeURIComponent('"A" B ± "') As its name indicates, Javascript decodeURIComponent function decodes encoded URI comopnent into corresponding original string value. encodeURIComponent should be used to encode a URI Component - a string that is supposed to be part of a URL.

#JAVASCRIPT DECODE URI COMPONENT CODE#
Review it again to see and understand the differences.I've been experimenting with various bits of Java code trying to come up with something that will encode a string containing quotes, spaces and "exotic" Unicode characters and produce output that's identical to JavaScript's encodeURIComponent function. In the example provided above, you have seen the same URI, both encoded and decoded. The decodeURIComponent() function converts a URL encoded string back to its normal form. Javascript URL decoding using the decodeURIComponent() function. This value contains textual data, therefore it is classified as a string. It uses UTF-8 encoding scheme to decode URI components. To put it simply, it is represents the decoded URI.
Return ValueĪs most JavaScript functions, decodeURIComponent() has a return value. In other words, the function won't know which URI to decode if you won't specify the previous URI, created with encodeURIComponent. The only feature to bear in mind is that the URI parameter must be included. Nevertheless, you should remember the set capitalization of it if you want your code to work and be less difficult to manage:Īs you can see, you should not have any issues when handling decodeURIComponent parameters. It is easy to understand even for those who are only starting to learn to code. The standard syntax for JavaScript decodeURIComponent function is not complicated.
