Trying to totalise and validate form

Hi

I'm having a bit of bother trying to make a questionnaire do what I
want it to. I have put it up on www.web-iq.co.uk/test.htm.

Basically the user of the final form (when I've tarted it up) will have
to choose 1 answer per line, which are added up in the totals below.
I've made four separate forms each of which totalises the number of
checked elements in it - ie. column one is its own form, similarly
column 2 etc.

All this is fine but at the moment the user can choose more than one
answer per row, which distorts the totals.

I tried experimenting with radiobuttons instead, but couldn't make it
work with unchecking.

I'm not great at javascript, so any help appreciated.

Page code below.

Thanks - Tim P

The first thing you have to do if thngs go bad,
is make a clean code you can grasp,
leaving out all the unneccesary parts.

Try this:

<table border=1>
<tr><td>

<table>
<tr>
<td><input type=checkbox id=r0c0 onclick='c(this)'> blah
<td><input type=checkbox id=r0c1 onclick='c(this)'> blah
<td><input type=checkbox id=r0c2 onclick='c(this)'> blah
</table>

<tr><td>

<table>
<tr>
<td><input type=checkbox id=r1c0 onclick='c(this)'> blah
<td><input type=checkbox id=r1c1 onclick='c(this)'> blah
<td><input type=checkbox id=r1c2 onclick='c(this)'> blah
</table>

<tr><td>

<table>
<tr>
<td><input type=checkbox id=r2c0 onclick='c(this)'> blah
<td><input type=checkbox id=r2c1 onclick='c(this)'> blah
<td><input type=checkbox id=r2c2 onclick='c(this)'> blah
</table>

<tr><td>

<table>
<tr>
<td><input type=checkbox id=r3c0 onclick='c(this)'> blah
<td><input type=checkbox id=r3c1 onclick='c(this)'> blah
<td><input type=checkbox id=r3c2 onclick='c(this)'> blah
</table>

<tr><td>

<table>
<tr>
<td>total <span id=c0>0</span>
<td>total <span id=c1>0</span>
<td>total <span id=c2>0</span>
</table>

</table>

<script type='text/javascript'>

function g(x){
return document.getElementById(x)
}

function c(x){

my = x.id
myRow = my.substr(1,1)
myCol = my.substr(3,1)

// only one or less checked this row:
if (x.checked)
for (var c=0;c<3;c++)
if (c!=myCol)
g('r'+myRow+'c'+c).checked=false;

// recomputes the 3 columns:
for (c=0;c<3;c++){
t=0
for (r=0;r<4;r++){
if (g('r'+r+'c'+c).checked)
t++
g('c'+c).innerHTML=t
}
}

}

</script>

Thanks Evertjan

This works great!

I've extended it to 10 rows and 4 cols with no problem (i.e. last row
is 9). But when I go to 12 rows the last two don't select only one col
correctly. I can't see why this would be from your code - not that i'm
much cop at javascript....

I have a feeling it is the substring method on MyRow which is doing
this because sometimes I want to extract 2 chars and sometimes 1?

Sorry to be a pain, but can you see what I'm doing wrong?

Thanks again for your help.

wrote on 08 jul 2006 in comp.lang.javascript:
I've extended it to 10 rows and 4 cols with no problem (i.e. last row
is 9). But when I go to 12 rows the last two don't select only one col
correctly. I can't see why this would be from your code - not that i'm
much cop at javascript....

Use double number rows starting at 10:

id=r10c3
id=r11c3

myRow = my.substr(1,2)
myCol = my.substr(4,1)


for (r=10;r<22;r++)

Hi Evertjan

Thanks for the reply - sorry I didn't thank you before - I've been away
and only got time to try out this code this morning.

As I said, I'm not good at javascript and I can't figure how to make
this work. I need the original definition of myRow and myCol for rows
1-10, so where do I put the new code please?

Sorry to be a nuisance and thanks again for your help.

Regards

TimP
