I have a string coming from a XML (which I can't edit) and I'd like to print it trough an alert in javascript.
Example of my string:
This is à string
And I need to print in an alert:
This is à string
is there a js html decode?

You need to show a little code which demonstrates how this values makes its way from the XML into the JS.JAAulde– JAAulde2013-02-18 13:13:00 +00:00Commented Feb 18, 2013 at 13:13

you could put the string in a dom element and read it out again, even without jquery: https://stackoverflow.com/a/3700369/1986499
Edit by recent demand to include some code from another SO answer:
var div = document.createElement('div');
div.innerHTML = encoded;
var decoded = div.firstChild.nodeValue;

Just because the question is a duplicate doesn't mean you should post a link-only answer.
var encoded = "This is à string";
var decoded = $("<div/>").html(encoded).text();
alert(decoded);

What this answer fails to mention is that, despite the question not being tagged with it, you need the jQuery library to use this answer. Without jQuery you'll be greeted with a lovely DOMException error.
I'm just a tiny bit late, but just in case anyone else finds this via Google (like I did), I thought I'd improve upon Imperative's answer.
function showbullet() {
var tempelement = document.createElement('div');
tempelement.innerHTML = "•";
alert("Here, have a bullet!\n" + tempelement.innerHTML);
}
showbullet();
I've tested this and confirmed it works in Chrome/43.0.2357.130 m; Firefox/32.0.1; Internet Explorer/9.0.8112.16421. There's no need to go mucking about with nodeValue's and what not; the entity will be replaced with it's associated character as soon as the assignment is complete. (Note, however, that doing alert(tempelement.innerHTML="•"); does not work in any of the browsers I tested!)
