I want to convert this string

&lt;p&gt;update this post&lt;/p&gt;

to

<p>update this post</p>

in Javascript.

Do you have any idea? Thanks in advance.

@Paul That one is focused on a specific entity, in addition to using jQuery. It was also asked later than the first one. — Asad Saeeduddin, Jan 06 '13 at 09:39

I'd create an element, set its innerHTML and get its innerText:

var element = document.createElement('div');
element.innerHTML = '&lt;p&gt;update this post&lt;/p&gt; ';
console.log(element.innerText);

The result is:

"<p>update this post</p> "

This works fine for hardcoded values, but beware of using this for user input. – Asad Saeeduddin Jan 06 '13 at 09:37

and, if you used jquery it would be as easy as this: `$('
').html('<p>update this post</p> ').text();` – keune Jan 06 '13 at 09:38
This works fine! Thanks. – nobinobiru Jan 06 '13 at 09:54

Working example:

var text='&lt;p&gt;update this post&lt;/p&gt;';
var d = document.createElement("div");
d.innerHTML=text;
alert(d.innerText || d.text || d.textContent);

You can use this method:

var param = '&lt;p&gt;update this post&lt;/p&gt'; 
unescape(param);

The `unescape`function (which is deprecated because it can't handle Unicode properly) doesn't work on that form of escaping. – Quentin Jan 06 '13 at 09:34
