• 1 You don't want to call your variable location, that's a reserved word. It didn't worked too well for me. – Kobi Commented May 3, 2010 at 9:50
• 1 @Kobi it's not a reserved word, it's just a global variable that browsers attach to the window object. – Matt Commented May 3, 2010 at 9:53
• 1 @Kobi location is not a reserved word. It is a client side object, so using it may be inadvisable but has no negative effects (unless you want to use the object). – Tomalak Commented May 3, 2010 at 10:00

There is no specific function in JavaScript which will decode HTML entities, however you can assign an innerHTML property to an element and then read it back.

x = document.createElement('div');
x.innerHTML = ""test"";
console.log(x.innerHTML); // => "test"

This will work for any HTML entities, not just "

edit:

As pointed out below, you're half-way there, you're just using the wrong property.

Change:

td_Details.innerText = location;

to:

td_Details.innerHTML = location;

For future reference, innerHTML is available in all browsers. innerText is not.

To remove the " just use the following:

location = location.replace(/"/g, '');

You may have actually meant to include the quotes in your output. To do so, do this instead:

location = location.replace(/"/g, '"');
