decodeURI

Summary

Gets the unencoded version of an encoded Uniform Resource Identifier (URI).

Syntax

decodeURI( URIstring )

Examples

The following code first encodes a URI component and then decodes it.

var uriEncode = encodeURIComponent ("www.Not a URL.com");
 var uriDecode = decodeURIComponent(uriEncode);

 document.write (uriEncode);
 document.write ("<br/>");
 document.write (uriDecode);

 // Output:
 // www.Not%20a%20URL.com
 // www.Not a URL.com

Remarks

The required URIstring argument is a value representing an encoded URI.

Use the decodeURI function instead of the deprecated unescape function.

The decodeURI function returns a string value.

If the URIString is not valid, a URIError occurs.
