UUID/GUID Javascript

Question

Is there a way to generate a GUID from Javascript?  I looked up at WRT reference, and I can't seem to find an obvious way to generate one.

Answer 1

No Sorry!

I think Jquery may have some functions you can use though:

I hit here looking for the same thing. there were many answers at stackoverflow to get a function in javascript. There are too many code snippets there, and one need to pick the right one for self.

For javascript based windows store app - it may be simpler to add a winrt (say commonlib) and add a NewGuid method there. I have used this option.

add a winrt component project say commonlib.

namespace commonlib
{
    public static class GuidUtils
    {
        public static System.Guid NewGuid()
        {
            return System.Guid.NewGuid();
        }
    }
}

For WinJS you should not drag in the .net runtime but code the winrt component in C++.

Something along the lines of

#include <windows.h>

namespace runtime { namespace guid {
  public ref class GUIDCreator sealed {
    public:
      static Platform::String^ CreateGuid() {
        GUID guid;
        HRESULT result = CoCreateGuid(guid);
        if FAILED(result) {
          throw ref new Platform::COMException(result);
        }
        WCHAR guidString[37];
        StringFromGUID2(&guid, guidString, 36);
        return ref new Platform::String(guidString);
      }
  };
} }
