为什么输出是乱码?
Win1.document.open();
Win1.document.writeln('<html><meta http-equiv="Content-Type" content="text/html; charset=GBK"><head><title>' + titleList[1] + '</title></head>');
Win1.document.writeln('<body bgcolor="' + tableBackColor + '" text="Black" link="Blue" vlink="Gray" LEFTMARGIN=0 onload="window.focus()">');
Win1.document.writeln('<center><FONT face="宋体" SIZE="-1"><b>'+LayerNameShow+'</b>');
Win1.document.writeln('</font></center></body></html>');
Win1.document.close();
