Decoding HTML Decimal encoded character

Question

Is there anything embedded in javascript that decodes an entry like " to " ?

I would need something similar to what is found here: http://www.hashemian.com/tools/html-url-encode-decode.php (the decimal decode).

check this link http://www.webtoolkit.info/javascript-url-decode-encode.html — Sandeep Manne, Apr 04 '12 at 11:37

Use the String.fromCharCode method. Example:

var entity = '&#34;';
var numeric = /\d+/.exec(entity);
var decoded = String.fromCharCode(numeric);

var dummy = document.createElement('textarea');
dummy.innerHTML = entity;
var decoded = dummy.value;

I'm receiving something like : System.out.println("TEXT"); and need to convert it to the readable form. – Sergiu Apr 04 '12 at 11:40
@Sergiu Then use the second method. For a single character, the first method is better, but the second one suits better in your case. – Rob W Apr 04 '12 at 11:42
You mean something like: var dummy = document.createElement('System.out.println("TEXT")); etc ? This does not work since it complains on invalid characters. – Sergiu Apr 04 '12 at 11:47
@Sergiu 1. `document.createElement` should be sticked to the **`textarea`** string. 2. You're missing the closing single quote on your string. Here's a working demo for your given string: http://jsfiddle.net/LGU48/ – Rob W Apr 04 '12 at 15:36
