Take a look at the attached file. It works for me. I hope it helps.

/* * File: Math.uuid.js * Version: 1.3 * Change History: * v1.0 - first release * v1.1 - less code and 2x performance boost (by minimizing calls to Math.random()) * v1.2 - Add support for generating non-standard uuids of arbitrary length * v1.3 - Fixed IE7 bug (can't use []'s to access string chars. Thanks, Brian R.) * v1.4 - Changed method to be "Math.uuid". Added support for radix argument. Use module pattern for better encapsulation. * * Latest version: http://www.broofa.com/Tools/Math.uuid.js * Information: http://www.broofa.com/blog/?p=151 * Contact: rob...@broofa.com * ---- * Copyright (c) 2008, Robert Kieffer * All rights reserved. * * Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: * * * Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer. * * Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution. * * Neither the name of Robert Kieffer nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission. * * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.
