嗨


这是怎么回事您可以使用Javascript来解决问题。

Hi
This is how you can use Javascript to solve the problem.

<asp:TextBox ID="txtHoursorAmount" runat="server"  onblur="transferValue()"/>
            <input type="hidden" name="hdnAmountorHours" id="hdnAmountorHours" runat="server" />

< br $>


脚本是

script is

<script type="text/javascript">
        function transferValue()
        {
            var inputVal = document.getElementById("txtHoursorAmount").value;
            document.getElementById("hdnAmountorHours").value=inputVal;
            alert(inputVal);
        }
    </script>

好​​运

Good Luck

在上面的解决方案中





更改

var inputVal = document.getElementById（txtHoursorAmount）。value;



要

in the above solution


change
var inputVal = document.getElementById("txtHoursorAmount").value;

To

var inputVal = document.getElementById('<%=txtHoursorAmount.ClientID %>').value ;

，设定值与上述相同.......

and set value as same as above.......
