怎么样再后台把text里面的内容赋值给label
document.getElementById('lblDate').innerHTML = document.getElementById('sDate1').value
不是 innerHTML  就是 innerText
呃~·那你去.net版块问吧~·发错地方了~·
想在把日历里面内容赋值到text里面的时候就让他执行，这个要写在哪里呢？谢谢了，我是新手
后台代码:
lblDate.Text = text.Value;
不过首先要
<input type="text" name="sDate1" id="sDate1" runat="server" value="" size="10" onclick="return Calendar('sDate1','sDate2');" />
将控制设置为 runat="server "
直接引用不就完了？
在后台控制必须要加input 必须加runat="server"属性，加上之后可以通过input的id来控制
