Reserved characters are those characters that sometimes have special meaning. The characters allowed in a URI are either reserved or unreserved (or a percent character as part of a percent-encoding). Percent-encoding in a URI Types of URI characters As such, it is also used in the preparation of data of the application/x-www-form-urlencoded media type, as is often used in the submission of HTML form data in HTTP requests. ![]() Although it is known as URL encoding, it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource Locator (URL) and Uniform Resource Name (URN). URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. The output shows that rather than encoding the whole URL, it encodes a particular part of the URL.For links within Wikipedia needing percent-encoding, see Help:URL § Fixing links with unsupported characters Also, we have encoded the "part of the URL using the encodeURIComponent(). After that, we used the encodeURIComponent() method to encode the ‘index.php’ part of the URL. We have taken the URL string containing the special characters. This example demonstrates the use of the encodeURIComponent() method to encode the part of the URL. The above code will produce the following output − https%20://Example 2 ![]() On compiling, it will generate the following JavaScript code − // URL which contains the spaces, as a special characters encode the URI to escape the special characters. URL which contains the spaces, as a special charactersĬonst demoURL = 'https ://les/i ndex.php' In the output, we see that space is escaped by %20, ‘’ is escaped by %3E. Here URI is a URI which needs to be encoded by escaping some special characters. Let encodedComponent = encodeURIComponent(URI) Users can follow the syntax below to encode URIs using the encodeURI() and encodeURIComponent() methods. The main difference between the encodeURI() and encodeURIComponent() method is that encodeURI() encodes the whole URL or URI, but encodeURIComponent() encodes the part of the URL which can be query parameters of the URL. Here, the escape sequence represents the UTF-8 encoding of the character. Both methods are the built-in library method which encodes some special characters such as spaces to one, two, three, or four escape sequences. The encodeURI() and encodeURIComponent(). There are two methods available to encode the URIs in TypeScript. If we don’t escape this kind of exceptional character, it may cause problems. So, we must escape the special characters such as ‘!’ and ‘space’ by using escape sequences, which we can do by encoding the URIS. So, we need to encode some characters which do not belong to the set of 128 ASCII characters. The answer is simple: URL should only contain the characters from the set of 128 ASCII characters. The first question that arises in your mind after reading this tutorial's title is why we need to encode and decode the URIs. ![]() The URL is a subset of the URI, which stores the document address on the web. ![]() In simple terms, URI is a string containing some characters, and we can identify the physical and logical resources on the web using the URI. We use the URL (uniform resource locator) to find the web page located on the internet. The URI stands for the uniform resource identifier.
