I have a web page that displays multiple records for a company. The
input text boxes that display my data are created dynamically. I'm
creating these input boxes dynamically because the number of records
for each company varies. The name of each input box increments by one
for each record (Ex: A1, B1, C1 | A2, B2, C2, etc..)
On my web page the user will enter in a number into the
txtGrossPayroll (some number) input box. I have added an
OnKeyDown="Comp utePremium()" and an OnKeyUp="Comput ePremium()" inside
my input boxes. When the user begins to type in a number the following
script runs and displays the premium inside the txtPremium(some number)
input box.
<script type="text/javascript" language="JavaS cript">
<!--
function ComputePremium( ) {
document.Schedu leForm.txtPremi um1.value =
Math.round((doc ument.ScheduleF orm.txtRate1.va lue *
(document.Sched uleForm.txtGros sPayroll1.value / 100)), 0);
}
// -->
</script>
Currently, I have the script so that it will only run for my 1st row of
records. Can the script be modified so that it is intelligent enough
to know the correct input box name to use? If so how?
I'm not very familiar with JavaScripts; sorry if this is something that
is very easy to do.
Thanks!

Because you have hard-coded the form control name.
Can the script be modified so that it is intelligent
enough to know the correct input box name to use?
Yes.
If so how?
By providing the row information as a parameter to the function call, in
some form, and then using bracket notation to reference the form
controls in the correct row.

It is very easy to do, but how it is specifically done depends on the
HTML being scripted.

I didn't think that that I needed to have OnKeyUp and OnKeyDown, but a
script that I used as a reference used both events. I went with how
they had created their script. Will either one of these accomplish
what I want?

Sorry about that. This is old code that I forgot to remove from the
desktop app that I'm converting and moving online.

some form, and then using bracket notation to reference the form
controls in the correct row.
Since I'm creating each input box on the server-side, I now see how I
can pass the row number to the function when the server is generating
the HTML. Can you provide an example of what the syntax looks like for
using bracket notation when referencing the form controls in the
formula?
Thanks for your help Richard!

Hi Richard,
I continued playing around with my function and came up with the
following:
function ComputePremium( i) {
document.Schedu leForm["txtPremium " + i].value =
Math.round((doc ument.ScheduleF orm["txtRate" + i].value *
(document.Sched uleForm["txtGrossPayrol l" + i].value / 100)));
}
So far, it seems to be working correctly. Is this what you were
refering to when you mentioned bracket notation.
Thanks,
CR Junk

Hi there,
I am dynamically created a table at runtime on an aspx form. The last
cell of each row contains a TextBox in which the user will enter
numeric values into.
Each textbox I create is given a name such as myTextBox0, myTextBox1,
... etc Basically the index of the loop that creates the table is
appended to the end of each TextBox name (ID).
