Convert escaped html ASCII codes to plain text using JavaScript

Question

I'm looking to convert a string of html entities specifying ASCII codes (ie: a) to the ASCII characters they represent (ie: a). I'm using a property of an object and trying to assign a value. For instance:

object.Text("");

When I pass is the string representing the entity, I get the same string back. I can't find the function to convert entities to the characters they represented.

The string "a" is an HTML character entity. Do you mean to ask how to HTML-decode a string? That's not really what you've asked. — Rob Kennedy

To convert all numerical character entities in a string to their character equivalents you can do this:

str.replace(/&#(\d+);/g, function (m, n) { return String.fromCharCode(n); })

I really like this solution, but do keep in mind that while   will be converted,   and other non-numeric escape codes will not.

Try the String.fromCharCode() function.

alert(String.fromCharCode(97));

As you can see, you'll have to strip out the ampersand and pound sign.

Best regards...
