![]() Here is an example: const query = 'Danke Schön' // perofrm encode/decode const encodedStr = encodeURIComponent (query ) const decodedStr = decodeURIComponent (encodedStr ) // print valuesĬonsole. The decodeURIComponent() method is suitable for decoding query string parameters and path segments instead of a complete URL. replace ('2B', '+') at the end will corrupt your data if the original (pre-x-www-form-urlencoded) contained that string, as xehpuk pointed out. It uses the UTF-8 encoding scheme to perform the decoding operation. Java's URLDecoder decodes the plus sign to a space, which is not what you want, therefore you need the replace statements. The decodeURIComponent() function is used to decode URL components encoding by encodeURIComponent() in JavaScript. log (url ) // output: !leearn javascript$/ decodeURIComponent() method Here is an example: const encodedUrl = '!leearn%20javascript$/' // decode complete URL const url = decodeURI (encodedUrl ) // print decoded URLĬonsole. The decodeURI () function decodes the URI by treating each escape sequence in the form XX as one UTF-8 code unit (one byte). In my case, Im using jQuery to get URL-ready form parameters, then this trick to build an object out of. forget to URI decode in the initial answer - which are small issues that can make things a lot more complex than they initially seem). It performs the reverse operation of encodeURI(). but its been done and tested already (Justin e.g. The decodeURI() function is used to decode a full URL in JavaScript. var uri 'Hello's ' var dec decodeURI(uri) alert(dec) document.write(dec) I finally used the below code and things worked var strName ('').html('Hello's').text() but still wondering why the original code doesn't work It seems to be a pretty straightforward use case.
Let us look at the JavaScript native functions that can be used for this purpose. But my FORM Query params may themselves have. Problem: All space characters i.e '20' is converted to '+' automatically. When this page is auto-refreshed, all form parameters are appended to url as HTTP GET parameter. However, in standalone applications, you have to manually decode query strings. Decode url '+' to '20' from Form GET query parameters. Mostly 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 original formats. ![]() ![]() URL decoding is the opposite of the encoding process. In this article, you'll learn how to decode an encoded URL in JavaScript. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. In an earlier article, we looked at different ways to encode a URL in JavaScript. Without seeing your code, it's hard to answer other than a stab in the dark. ![]()
