Multiple variables in for statement

[ASchweti]

Hi there,

I've written some code to calculate a price based on some options choosed by the client.

Now I would like to multiply this code by using a for statement and I am wondering if there is a way to have different variables for each run.

What I mean:

I have e.g.

for (i=1; i <= 3; i++) {
...
ammount1 = 0;
...
}

If i=1 the variable should be ammount1, if i=2 it should be ammount2 and so on. Is there a way to do this? ammount+i = 0 obviously doesn't work

Thanks and regards,

You could use an array

var amounts = new Array();
for ( var i = 0; i < 3; i++ )
{
	amounts[i] = 0;
}

Will that work?

I am trying to solve this at this very moment, so I was playing around with arrays when I received your reply.

So to me it sounds like the logical solution, but I am getting a "amount is not defined"

Any idea why?

I believe I found it?

My smart O'Reilly book told me to add

amount = new Object();

It seems to work. Is that the correct way to go?

Thanks ASchweti

I'd have to see more of your code to understand the error.

Hi Beetle,

just read my second post right after yours, that I solved this issue. I just was not sure if I solved it the correct way?!

Anyhow I am facing another problem!

In order to calculate different amounts based on user entries I am using PHP to create the appropriate amount of forms.

The form fields are named e.g. color1 on the first form, color2 on the second form. In order to calculate the price I would need to get a hold of the values.

So again if i=1 I need to check

document.form.color1.checked

if i=2 I need to check

document.form.color2.checked

an so on...

Do you know what I mean? Is there a way to keep this flexible as well?

[beetle]

yes

document.form.elements['color'+i].checked
