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).

Use the String.fromCharCode method. Example:

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

A general HTML entity-to-character method is:

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 Then use the second method. For a single character, the first method is better, but the second one suits better in your case.

You mean something like: var dummy = document.createElement('System.out.println("TEXT")); etc ? This does not work since it complains on invalid characters.

@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: jsfiddle.net/LGU48
