I have a for loop seen below....
var the_form = document.getEle mentById(formNa me);
for(var i=0; i<the_form.leng th; i++)
{
var temp = the_form.elemen ts[i].type;
if (temp == "radio")
{
for (x = 0; x < the_form.elemen ts[i].length - 1; x++)
{
//do stuff
}
}
}
Right before the inside loop I do the following and next to its the
results, any idea why the last one returns 0?
alert(the_form. elements[i].id); // returns question1
alert(the_form. question1.lengt h); // returns 4 (amount of radio
buttons in that group)
alert(the_form. elements[i].length); // returns 0
I cannot figure out why this is the case. Am I blatantly looking over
something? 9 9304

What exactly are you trying to accomplish here?

Well I am using an AHAH library (flavor of Ajax) to do my loading of
content into div's. In this case I am adding in form validation and
the way the library is written I have to do some validation this way.
Basically I am trying to tell if a radio button in the list is selected
and I want to add some HTML into a span if no radio button is selected.
Does that make sense?

OOps I am basically trying to loop through each radio button list ( I
have more than one) in this form elements collection.

one way to do it would be to just loop over the radio button's
themselves:
<script type="text/javascript">
function test() {
q1Radios = document.the_fo rm.question1;
for (x=0; x < q1Radios.length ; x++) {
if ( q1Radios[x].checked )
alert(q1Radios[x].value)
}
}
</script>
<form name="the_form" >
<input type="radio" name="question1 " value="1" />
<input type="radio" name="question1 " value="2" />
<input type="radio" name="question1 " value="3" />

I need to reference the elements though, if I use q1Radios =

through the elements and need to reference the radio buttons as an

I cannot hardcode the radio button id is what I mean I need to
reference it as elements[i] I am trying to make this code scalable.
q1Radios = document.the_fo rm.question1;

This solution works great thanks, but my only thing is I lose my
ability to have the text area's in the collection called getradios. No
would the logical thing be to do two collections and add them together?
i.e.
getRadios = document.getEle mentsByTagName( "input")
getTextAreas = document.getEle mentsByTagName( "textarea")
then do some sort of getRadios.add ??? Adding collections together is
that the right way to do it or is there a better way? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

We have a 10-question quiz for kids, each question being a yes or no
answer using radio selections. I'd like to keep a current total of
yes's and no's at the bottom of the quiz (if the user selects yes to
question 1, the total of yes's increases by 1). I've been searching for
a while but I'm not sure I'm searching with the right keywords. Can
