<script language= "JavaScript " type= "text/javascript ">
function selectfenlei(Obj)
{alert(Obj);
var b=window.opener.document.all.form1.select2;
alert(b.value);
b.options.add(new Option(Obj,Obj));
}
</script>
<a href=# onclick= "javascript:selectfenlei(this.innerText); "> 美图欣赏 </a>
------解决方案--------------------function selectfenlei(Obj)
{alert(Obj);
var b=parent.document.getElementById( "select2 ");
// clear all
b.options.length = 0;
// add
b.options.add(new Option(Obj,Obj));
}
