This is why, it becomes necessary to decode query strings or path parameters passed in URLs to get the actual values. Any character outside this allowed set is encoded using URL encoding or Percent encoding. These characters include Alphabets ( A-Z a-z), Digits ( 0-9), hyphen ( -), underscore ( _), tilde ( ~), and dot (. URLs, as you might know, can only contain a limited set of characters from the US-ASCII character set. It is also used to decode HTML form parameters that are submitted with application/x-www-form-urlencoded MIME format It is used to parse query strings or path parameters passed in URLs. URL decoding is the inverse process of URL encoding. What is URL Decoding and why is it required? Do check that out if you want to encode URL components. You should definitely check them out in the blog section.
Our website also contains various articles about how to decode URLs in different programming languages. The world wide web consortium recommends using UTF-8 encoding scheme when working with URLs. © in your URL will be interpreted as © (the is not mandatory in SGML as it is 'implied'. This breaks whenever you have a variable that matches an HTML entity, like 'gt' or 'copy' or whatever. Note that, our tool assumes that the input is encoded using UTF-8 encoding scheme. The reason why & works 'most of the time' is that browsers are forgiving and just decode the & as the &-sign. Once your input string is decoded, you can click in the output text area to copy the decoded URL. If these special characters where to show up in unexpected places the parsing would. The key sections of a URL are divided up by special delimiter characters. If the input is not a valid URL encoded string, then the input text area will turn red and the output textarea will be cleared. URL formally stands for ‘Uniform Resource Locator’, The URL is a string that has to be parsed programatically, this means that it has to abide by certain rules. Get started by typing or pasting a URL encoded string in the input text area, the tool will automatically decode your input string in real time. URL Decoder is the #1 online tool for decoding URLs. Here is an example: const query = "Danke Schön" // perofrm encode/decode const encodedStr = encodeURIComponent (query ) const decodedStr = decodeURIComponent (encodedStr ) // print valuesĬonsole.
You should use decodeURIComponent() to decode query string parameters and path segments instead of full URLs. It uses 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$/ decodeURIComponent() Here is an example: const encodedUrl = '!leearn%20javascript$/' // decode complete URL const url = decodeURI (encodedUrl ) // print decoded URLĬonsole. It performs the reverse operation of encodeURI().
The decodeURI() function is used to decode a full URL in JavaScript.
Let us look at the JavaScript native functions that can be used for this purpose. However, in standalone applications, you have to manually decode query strings. Most of the time, encoded query string parameters are automatically decoded by the underlying framework you're using like Express or Spring Boot. It converts the encoded URL strings and query parameters back to their normal formats. URL decoding is the opposite of the encoding process. In this article, you'll learn how to decode an encoded URL in JavaScript. In an earlier article, we looked at different ways to encode a URL in JavaScript.
