Javascript into ASP.Net Simple example wanted.. Sum Textboxes client side

[Davisro]

I would like to have a total box show the totol of four textboxes when
anyone of them change.

I know I could do this via postback, but would like to do this on client
side utilizing javascript.

I am familiar with asp.net but not in how to migrate javascript into the
html.

Thanks,

Rog

if you want it with clientside javascript I suggest you look at a clientside
javascript newsgroup.
you'll probably have to catch the keydown/keyup in the boxes.

Here is one idea (will need tweaking):

<input type="text" id="sumBox" name="sumBox" onFocus="SumBox es();" />
<script language="JavaS cript">
function SumBoxes()
{
var val1 = form1.addBox1.V alue;
var val2 = form2.addBox1.V alue;
var val3 = form3.addBox1.V alue;
var val4 = form4.addBox1.V alue;

//May need test for "" on each box here, turn to 0, like
if(val1 == '')
{
val1 = 0;
}

form1.sumBox.Va lue = val1 + val2 + val3 + val4;
}
</script>

I would like to use WebForm Textboxes as I have a lot of .Net code that
relates to them. Is this possible in mostly the same way you stated above?

For insert JavaScript on client page you can use RegisterClientS criptBlock
or RegisterStartup Script method.
string s = "<script language=\"Java Script\">\n" +
"function SumBoxes()\n" +
"{\n" +
............
"}\n" +
"</script>\n";

RegisterClientS criptBlock("SUM ", s);

for attach this function to your textbox you can use this code :
txtBox1.Attribu tes["OnChange"] = "SumBoxes() ;";
