要完成此效果把如下代码加入到区域中 <script language=JavaScript> function copy(ob){ var obj=findObj(ob); if (obj) { obj.select();js=obj.createTextRange();js.execCommand("Copy");} } function cut(ob){ var obj=findObj(ob); if (obj) { obj.select();js=obj.createTextRange();js.execCommand("Cut");} } function findObj(n, d) { //v4.0 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);} if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i </script>
