JS: Loop through TextBoxes

Hey everyone,

There was a similiar question answered on the forum, but I couldn't quite use it for what I need done.

I have some textboxes: shire1, shire2, shire3, ...
And I want to create a string of their values:

for (i = 1; i <= amount; i++)
{
SendTo = 'shire' + i;
alert(document.frm.SendTo.value);
SendToString += '; ' + document.frm.SendTo.value;
}

I thought I used similar code before but for some reason it is saying "Sendto.value" is not an object.

What am I doing wrong?

Thanks!

SendTo is a string, not the object you want.
Use eval('document.frm.shire' + i + '.value')
or better have a look at getElementById()
