<script type="text/javascript">
var messages = new Array();
messages[0] = "128";//这里写入每个选项对应的说明文字
messages[1] = "108";
messages[2] = "402";
function messageReveal(str) {
var name="document.buyform.n"+str+".selectedIndex";
var messageindex = eval(name);
h = messages[messageindex];
document.buyform.y1.value = h //如果y1是变量这个要怎么写?
}
</script>
<tr>
