Set Clipboard Property value from Javascript variable

I have a javascript which is retrieving parameters from the URL. There is a clipboard property which should be set as the parameter value fetched by javascript.

I tried using pega.u.d.setProperty("$PpxRequestor$pTileToOpn", myTile);

But it didn't work.

A quick reply will be very helpful
