Hi,

In asp.net , i have 2 textbox control. In which, i will enter the value and on it key pressed value, i have to display the amount.

Used Javascript function.

On first key press , the event called, but no value is displaying in the second textbox.

On second number key press, showing the value for the first typed number...

I don't understand why on very first time, it is not showing the value eventhough script function is called...

Can anybody guide me to solve this issue

Code

<input type="text" id=txt1 />
<input type="text" id=txt2 />

$('#txt1').keypress(function ()
{
$('#txt2').val()=$('#txt1').val();

});

Thanks.

Which technology you are using for showing the amount..?
And elaborate your question ? are you trying to implement auto complete text box?

How about showing some minimal but comprehensive code sample to reproduce the problem?

Try to use onkeyup

ASP Code

ASP.NET

<asp:textbox id="TextBox1" onkeyup="show()" runat="server" xmlns:asp="#unknown"></asp:textbox>
<asp:textbox id="TextBox2" runat="server" xmlns:asp="#unknown"></asp:textbox>

Javascript Code

JavaScript

<script type="text/javascript">
        function show() {
            var txt1 = document.getElementById("TextBox1").value;
            document.getElementById("TextBox2").value = txt1;
        }
</script>

I hope my idea is right. :)
