opener有关系:父窗口:
<form name=form1>
<select name=parentList>
<option>请选择
</select>
</form>
<script language=javascript>
function writeParentList(str)
{
if(str=="") return;
if(document.form1.parentList)
{
e = document.form1.parentList;
var newOP=new Option(str, str, true, true);
for(var i=0; i<e.options.length; i++) //不重复
if(e.options.value == str) return;
e.options[e.options.length] = newOP;
}
}
</script>
<input type=button value=ok onclick="window.open('ttt.htm','meizz')">
子窗口:
<select onchange="if(window.name!='')opener.writeParentList(this.value)">
<option>请选择
<option value=aaa>aaa
<option value=bbb>bbb
<option value=ccc>ccc
<option value=ddd>ddd
