欲通过按下ENTER键，使INPUT获得SELECT中选定的值，代码如下，请填充entergo()

function copyList()
{//获值
var sel = false;
for (i=0;i<document.xform.select1.options.length;i++)
{
var current = document.xform.select1.options[i];
if (current.selected)
{ sel = true;
txt = current.text;
val = current.value;
document.xform.getvalue.value=current.value;
}
}
if (!sel) alert ('你还没有选择任何项目!');
}

function entergo(){
//if (window.event.keycode==13)
// {
//copyList()
//alert("dddddd");
//}
//getvalue.value=select1.value
//select1.blur
//tip.style.visibility="hidden"
//event.keycode=9
}

</script>
<form name=xform id=xform>
<input type=button value="获得" onclick="ff()" id=button1 name=button1>
<DIV id=tip style="BORDER-RIGHT: #3366cc 1px solid; BORDER-TOP: #3366cc 1px solid; BORDER-LEFT: #3366cc 1px solid; WIDTH: 80px; BORDER-BOTTOM: #3366cc 1px solid; POSITION: absolute; HEIGHT: 20px; BACKGROUND-COLOR: #d2e8ff">

兄弟，你明白我意思啊。欲通过按下ENTER键，使INPUT获得SELECT中选定的值，代码如下，请填充entergo()，使INPUT获得SELECT中选定的值是关键,entergo()是input的onkeydown事件，我忘记加了。

[zhangguagua]

entergo()
{
document.all.yourttextname.value=document.all.selectname.options[document.all.selectname.selectedIndex].value;
}

楼上的GG，我是想通过判断window.event.keyCode==13，来进行。不知道option里面为什么不相应键盘按下事件

[孟子E章]

if (window.event.keyCode==13)

<INPUT name=getvalue onkeydown="entergo()" id=getvalue style="LEFT: 88px; TOP: 61px"></
