楼上兄台思路很正确不过貌似忘加了点什么.
select 标签要记得赋值
<select name="status" onchange="showTime(this)">
<option value="New">New</option>
<option value="Pending">Pending</option>
<option value="Complete">Complete</option>
</select>
脚本:
<script language="javascript">
function showTime(obj){
if(obj.value=="Complete"){
//这里直接用new Date()的话显示的会比较难看,可以转化一下
//document.getElementById("completeddate").value=new Date();
var date = new Date();
var newDate = date.getYear()+"年"+(date.getMonth()+1)+"月"+date.getDate()+"日";
document.getElementById("completeddate").value = newDate
}
}
</script>
