要完成此效果把如下代碼加入到區(qū)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>
