Getting my client-side variable over to server-side
Ok so I have looked at a few posts on this subject and I can't quite figure out how to apply the idea to what I am doing here.
I am using javascript to take amounts from 7 different textboxes and add them up on the fly, dropping the total in the 8th textbox.
After they fill in that information they click button (postback) to continue throughout the form... what I need is for the "textboxTotalAmt" to move from client-side to server-side. So I can access that total amount later in the form.
Here is the Javascript piece...
<script type="text/javascript"><!--
function ValidNumber(e)
{
if(isNaN(e.value))
{
e.value = "0.00";
}
else
{
e.value = ""+Number(e.value).toFixed(2);
}
return e.value;
}
function CalTotal1()
{
var varTotalGeneral
var vartotal1 = ValidNumber(window.document.getElementById('textbox01'));
var vartotal2 = ValidNumber(window.document.getElementById('textbox02'));
var vartotal3 = ValidNumber(window.document.getElementById('textbox03'));
var vartotal4 = ValidNumber(window.document.getElementById('textbox04'));
var vartotal5 = ValidNumber(window.document.getElementById('textbox05'));
var vartotal6 = ValidNumber(window.document.getElementById('textbox06'));
var vartotal7 = ValidNumber(window.document.getElementById('textbox07'));
varTotalGeneral= parseFloat(vartotal1) + parseFloat(vartotal2) + parseFloat(vartotal3) + parseFloat(vartotal4) + parseFloat(vartotal5) + parseFloat(vartotal6) + parseFloat(vartotal7);
window.document.getElementById('textboxTotalAmt').value = ""+varTotalGeneral.toFixed(2);
}window.onload=function(){
CalTotal1();
}
//--></script>Any help would be appreciated

itsumapathyk What do you try to do?
if you want to implement server side function+client side function in one button click. You need to use ClientScriptBlock or more popular technique, AJAX

webberman Maybe I've misunderstood the question, but can't you just access the textboxTotalAmt's text in the handler of the button? Just store it in viewstate if you want to keep the value for later on like ViewState("textboxTotalAmt") = textboxTotalAmt.Text.
We're all in this together.

conankingofcool Any reason why you can't use server side function to calculate the total and put it to the 8th textbox? This would've been much easier appoarch.

photoshoper Well I ended up figuring out a way to get what I needed without having to pass the javascript variable.
Basically the javascript is just being used for 'pretty' purposes now and I just created server-side code to add up the fields for the final total. As I see somebody just suggested as well.
Thanks

toneez Create one hidden server variable and assign the total value in it.
You will able to access the the hidden field in server side.
input type="hidden" id="txtTotal" runat="server"
Please mark it as answer if it resolves the issue.

Server side Variable in client side script
Hello, I want to access the variable defined in the server side script from the client side. Can anyone help out with an example ???

Loading client side variables from server side code
Just curious whether anyone has seen a better way to implement the following. It doesn't seem like the best way! What I'm doing is passing in an array of values to the client via server side code. The reason for this is because I'd like the server to do most of the crunch work and then pass the final results to the client. I use the 'onload' event of an image. code behind: imgLoader.Attributes.Add("onload", "Init('Tag1;Tag2;Tag3')") client-side. The page also contains an image called 'imgLoader'. var Entities = new Array(); function Init(s) ...
