Note that the encode method, will convert every single character into its html character. Code Beta 1,876 Dependents 40 Versions html-entities Fastest HTML entities library. It decodes all escape sequences, including those that are not created by encodeURIComponent, like -.' (). decodeURIComponent () uses the same decoding algorithm as described in decodeURI (). It doesn't provide too much customization but it works fine (at less to have only a couple of lines). Description decodeURIComponent () is a function property of the global object. This includes the expected encoding of the data, and how decoding errors are handled. The decoding method is defined in the current TextDecoder object. The encodeURI () 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). As such, I believe as well that it would be beneficial to share two. This is one of the most commonly used libraries for encoding and decoding HTML entities. The external library we will be using is the he library. One way is by using vanilla JavaScript, and the other is by using an external library. It expects as first parameter the string (decoded or encoded acording to the method) and returns the processed string. The code () method returns a string containing text decoded from the buffer passed as a parameter. There are no JavaScript built-in functionalities to encode or decode HTML entities. There are two ways to decode HTML entities.

This piece of code works like a charm in both ways, encode and decode. If you're one of those psychotic (just like me) developers that doesn't like to add huge portion of code in their projects, you may want to use the following snippet. Javascript itself doesn't provide native methods to deal with it, unlike PHP (our beautiful server side language) which offers the htmlentities, html_entity_decode and html_entity_encode functions ready to use. If you use the DOM API, you don't have to care about escaping at all.Invalid html, broked markup and other undesirable side-effects of work with html strings without being escaped properly in Javascript, is a problem that at least 1 of every 5 web developers (that works with dynamic apps) have faced. Quotes escaping is needed when you're constructing HTML as a string with untrusted or quote-containing data at the place of an attribute's value.

It is done context-dependently, that's why this jQuery method doesn't encode quotes and therefore should not be used as a general purpose escaper. The hexadecimal characters in a string will be replaced by the actual characters they represent using unescape () method. This method takes a string, which is encoded by escape () method, and decodes it. Also you can see that in the resulting HTML not everything is encoded, only the minimum that is needed for it to be valid. In JavaScript, to decode a string unescape () method is used. So if your final goal is to insert some data into the document, by doing it this way you'll be doing the work twice. by accessing innerHTML - this is what happens when you run $('').text(value).html() suggested in other answers.

** Unless you explicitly convert it to actual HTML afterwards. * This answer is not intended for server-side JavaScript users (Node.js, etc.) mati at 12:52 2 As strings containing HTML entities are something different than escape d or URI encoded strings, those functions won't work. Var el = document.getElementById('first') Ī.textContent = 'Search for "exact" term' Ĭonsole.log(a.outerHTML). 15.3k 14 46 62 The huge function included in this article seems to work fine: /b/aoakley/archive/2003/5.aspx I don't think that's the most clever solution but works.
