Same way, if the URL or URI is encoded using the encodeURI() function, you should use decodeURI() to properly decode it and if specific components are encoded using the encodeURIComponent() function, you should use decodeURIComponent() to decode those specific components. If you don’t have a specific requirement and just want to encode the URL or URI before transmitting it to the web, you can use encodeURI(), but remember, if you only want to encode specific components of the URL, such as query parameters, you should use the encodeURIComponent() functions. Remember to follow best practices to avoid issues and ensure the security of your web applications.In this tutorial, we have looked at the importance of encoding a URL or URI and learned about several functions that JavaScript provides which take URLs as input to encode and decode them with their respective code examples. By using the encodeURIComponent() and decodeURIComponent() functions, you can safely encode and decode URLs with ease. URL encoding and decoding are essential skills for web developers working with URLs in JavaScript. Be aware of security vulnerabilities such as SQL injection that can occur when decoding user input.Avoid encoding the entire URL as a single string, as this can cause issues with special characters in the domain name or protocol.Use the decodeURIComponent() function to decode individual components of a URL, such as query parameters.Use the encodeURIComponent() function to encode individual components of a URL, such as query parameters.Always encode URLs before passing them as parameters in a request.When working with URLs, it is important to follow best practices for encoding and decoding to avoid issues such as broken links or security vulnerabilities. We use the decodeURIComponent() function to decode the URL, which replaces all encoded characters with their original form. In this example, we have an encoded URL that we want to decode. Here is an example: const encodedURL = "https%3A%2F%%2Fsearch%3Fq%3DJavaScript%20Tutorial" Ĭonst decodedURL = decodeURIComponent(encodedURL) In JavaScript, you can use the decodeURIComponent() function to decode a URL component. This is useful when you need to extract parameters from a URL that has been encoded. URL decoding is the process of converting encoded characters back to their original form. We use the encodeURIComponent() function to encode the URL, which replaces all special characters with their corresponding ASCII codes. In this example, we have a URL that contains a query parameter. Here is an example: const url = " Tutorial" Ĭonst encodedURL = encodeURIComponent(url) Ĭonsole.log(encodedURL) // "https%3A%2F%%2Fsearch%3Fq%3DJavaScript%20Tutorial" In JavaScript, you can use the encodeURIComponent() function to encode a URL component. This means that any character that is not a letter, number, or one of the following characters: - _. URL encoding is the process of converting special characters to their corresponding ASCII codes, which can be safely transmitted over the internet. In this article, we will explore how to decode and encode URLs in JavaScript. This is where URL encoding and decoding come into play. However, URLs can also contain special characters, such as spaces, question marks, and ampersands, which can cause issues when passed as parameters. URLs are made up of different components, including the protocol, domain name, path, and query string. URLs are an integral part of the internet, and they are used to identify web resources such as web pages, images, videos, etc.
