hello programmers, got a problem here. As you see all i want is to automatically add all the vlues stored on all the text boxes. Ive tried many ways including setting textmaterial2 autopostbact to true and put the solution on txtTE2 but still it doesnt work. I dont know if my java script is correct. Plss help. Is there any possible solution here?

<script language="javascript">
function keyUp() {
            if (document.getElementById("txtmaterial2").value == "") {
                document.getElementById("txtTE2").text == "";
            }
            else {
                document.getElementById("txtTE2").text = Round((CDbl(txtmealallowance2.Text) + CDbl(txttransportationallowance2.Text) + CDbl(txtPerDiem2.Text) + CDbl(txttransportation2.Text) + CDbl(txtaccomodation2.Text) + CDbl(txtmealven2.Text) + CDbl(txtconsultant2.Text) + CDbl(txtmaterial2.Text)), 2);
            }
        }

推荐答案

CDbl是vbscript函数
您正在调用的javascript中是否有任何自定义设计的函数"CDbl"?

一些提示:

1.使用jquery使用javascript简化生活.
2.如果使用IE打开开发人员栏(firefox中的萤火虫)并调试javascript，则可以轻松看到错误.

CDbl is a vbscript function
do you have any custom designed function ''CDbl'' in your javascript that you are calling?

some tips:

1. Use jquery to make your life simpler in javascript.
2.if using IE open developer bar (firebug in firefox) and debug your javascript, you can easily see your error.

尝试以下代码:

Try this code:

<script language="javascript">
function sumquinto()
{
var Sumbog=0;
var val1= parseInt(document.getElementById("textbox1").value);
var val2= parseInt(document.getElementById("textbox2").value);
var val3= parseInt(document.getElementById("textbox3").value);
var val4= parseInt(document.getElementById("textbox4").value);
var val5= parseInt(document.getElementById("textbox5").value);
var val6= parseInt(document.getElementById("textbox6").value);
etc


if (val1 >=0)
{
Sumbog= Sumbog + val1
}
if (val2>=0)
{
Sumbog=Sumbog+val2
}
if (val3>=0)
{
Sumbog=Sumbog+val3
}
if (val4>=0)
{
Sumbog=Sumbog+val4
}
if (val5>=0)
{
Sumbog=Sumbog+val5
}
if (val6>=0)
{
etc
}
document.getElementById("txtTE2").value=Sumbog
}
</script>
<asp:TextBox ID="TextBox1" runat="server" onkeyup="sumquinto();"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server" onkeyup="sumquinto();"></asp:TextBox>
<asp:TextBox ID="TextBox3" runat="server" onkeyup="sumquinto();"></asp:TextBox>
<asp:TextBox ID="TextBox4" runat="server" onkeyup="sumquinto();"></asp:TextBox>

并且在您的解决方案文本框中不要添加onkeyup事件.

and on your solution textbox dont add the onkeyup event.

试试这个:

Hi,

Try this:

function keyUp() {
        var mealallowance2 =
