DvMsg. style. border = "1px solid # 6699dd ";
DvMsg. style. zindexes = "1112 ";
Document. body. appendChild (dvMsg );
Document. getElementById ("msg "). style. top = document.doc umentElement. scrollTop + (document.doc umentElement. clientHeight-document. getElementById ("msg "). offsetHeight)/2 + "px ";
Document. getElementById ("msg "). style. left = document.doc umentElement. scrollLeft + (document.doc umentElement. clientWidth-document. getElementById ("msg "). offsetWidth)/2 + "px ";
Var imgs = document. createElement ("p ");

}

Function scrollps ()
