。怎么在js里打开指定窗口大小

求助。如何在js里打开指定窗口大小
问题如下，
我要在首页里调用js

然后要在JS   里指定打开窗口的大小。

我现在的js文件如下

document.writeln( "     <li   class=\ "W8   L\ "> ");
document.writeln( " <span   class=\ "rl   lt   l_z_o\ "> ");
document.writeln( " <td   width=40   > <label> <input   name=id   type=\ "checkbox\ "   class=\ "checked\ "   id=\ "id\ "   value=\ "109276\ "> <\/label> <a   href=\ "MusicPlay\/3742\/ylmv_109276.html\ "   target=\ "Ylmv\ "   title=\ "杨伟汉   -   爱那么简单\ "> 爱那么简单 <\/a> <\/td> ");
document.writeln( " <\/span> ");
document.writeln( " ");
document.writeln( "                                                                             <LI   class=\ "W   R   oC\ "> <td   width=20   > <a   href=\ "MusicPlay/3742/ylmv_109276.html\ "   target=\ "Ylmv\ "> 试听 <\/a> &nbsp;&nbsp; <td   width=20   > <a   href= "# "   onClick=/ "window.open( 'http://code.5k3g.com\/NewSend2\/sendring_4.aspx?songname=爱那么简单&uid=10562\ ', '_blank ', 'width=350,height=350,scrollbars=no ') "> 铃声 <\/a> <\/td> <\/li> ");
document.writeln( " ");
document.writeln( "                                     <\/a>   <\/span> ");
document.writeln( " <\/li> ");

但是在首页显示不出来。
一片空白。请高手指教.
