   example of Token Generation mentioned in this article , I suggest you stop using it, if the first line takes the height of the Token because of the compatibility issue of the receiver, the token is completely invalid. in addition, there is no intention of using two highly comparable methods, and some of them have a poor sense.

   try {

   v ar bheight = iframe.content?#doc ument. body. scrollheight;
   var dheight = iframe.content##document.doc umentelement. scrollheight;

   }catch (Ex) {}
