Validation To Add Radio Support?
May 9, 2011
I am using a script called osDate and I am trying to modify the sign up form to suit my setup. So far I have the below, but I would like to check a set ofradio buttons, but not sure, how to add it into the current code.
var alphanumeric_chars = "0123456789.+-_#,/ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz ()_";
var alphanum_chars = "0123456789_ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
var text_chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz /'";
var full_chars = "0123456789.+-_#,/ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz() _$+=;:?'";
[Code]...

I'm trying to get a radio button validation for different sets of radio buttons that simply contains Yes & No buttons.
Here's what I'm trying to do:
Question 1: if Yes, then (Alert 1) if No, then (Alert 2) (if Yes, then Question 2 appears) *Up to here I'm happy- can't figure out the rest*
Question 2: if Yes, then (Alert 1) if No, then (Alert 2) (if Yes, then Question 3 appears)
I need the Alerts to be swapped from this point*
Question 3: if Yes, then (Alert 2) if No, then (Alert 1) (if NO, then Question 4 appears)
Identical for Question 5, and for Last Question 6 Alerts swapped back again.)
Here's the script that I managed to piece together:

i'm running a validation script to check if my radio buttons are selected, but i can't seem to get it to read the value of the field.
heres my form
<form name="cases" action="cases_process.php" method="post" onsubmit="return validate(this)">
<input name="uscan" id="uscan" value="n" checked="checked" type="hidden" />
<input type="radio" name="uscan" id="uscan" value="us" class="radial" tabindex="1" /><label>United States</label>
[Code]....
everything works up until the if(uscan == "n") so idk why it cant find what the value of the field is, because ive tested it and it seems to know even know what the value is.

I wrote a function to to validate some elements in my form and for some reason I can't seem to figure out why my radio validation is not working. There are about 3 to 4 radio buttons. all with the same name, but i need to make sure that at least one out of this group is selected.
Below is my code.
JS:
<script type="text/javascript">
function validate_required(field,alerttxt,select)
{
with (field)

I've got 4 radio buttons on an html page.
named: account_can | options, Yes & No / 1 & 0
named: account_usa | options, Yes & No / 1 & 0
my script:
function checkcurrency(){
var strCan = document.supplier.account_can;
var strUS = document.supplier.account_usa;
if(strCan.value==1 && strUS.value==1){
alert("The supplier must be either a Canadian or US account, it can not be both.");
return false;
}
return true;
}
every time i submit the form, it goes through no matter what i've selected. and I have added this to the form onsubmit tag. so I'm not sure why this isn't working.. any ideas?

I am trying to validate my radio groups. I have a page which has about 30 questions. I have created a radio group for each questions. All questions are in a form. I just want to validate the radio buttons/groups to make sure all questions are answered when the submit button is pressed. I dont care which one is selected.

For some reason when I try to submit my form in IE8 it doesn't get past the radio group.It keeps asking me to select an age even after one has been selected. Validation works but it's not picking up that I have selected one of the items within the group.

I'm working on validating radio buttons in a form. I want to require that a button be selected from required radio button groups before accepting the submit. Not all the radio button groups are required to have a selection.
One problem I'm having is that I can't return the name of the radio button group. I want to switch case on the name of the radio button group.
I do have an id for each individual radio button, so I can confirm that the for loops are working, but my alert tells me that radiogroups[j] is an [object] and radiogroups[j].name is undefined.
And there is a problem with the logic, too. If just one of the radio button sets is checked, the form validates. Code:

I can't seem to get a alert/popup when checking if on the form no radio button selection has been made...
<script type="text/javascript">
function validate()
{
if (document.orderForm.groupSize[0].checked == false )
{
alert ("none selected")
[Code]...
I want to check all 4 radio buttons in this example and show a message if none have been picked...

I'm using it for form validation. The way I have it set up works great to validate the text areas of the form, but I also have a field of radio buttons that I need the user to select at least one radio button. Here's how I have the validation code set up: Code:

I'm having a problem with some code, here's the code below:
HTML Code:
If someone hits submit without selecting yes or no the validation pops up asking them to make the selection. After they close out the pop up box the form action still passes them along to the congratulations_aff.php page.
How and why is that passing them on even if they didn't make a selection with the radio buttons?

I'm working on a form. The one thing i can't get to work is the following:
When a radio button "creditcard" is checked, the form can only be submitted if the age in the textfield(on the top of the page, textfield "leeftijd") is over 18.

I'm getting into javascript coding and i'm stumped with some problem about radio buttons. What I would like is to have a general function where I can pass in any group of radio buttons and have it return the textual value of the radio button selected.
First, here is my code so far.
Now here's a sample form:
My question is, when i run this function and pass it in the group of radio buttons by means of the onclick event handler, firefox 3.6.22 reports in the error console on line 22 that "options[index] is undefined". It seems that if i use the variable "index" more than one time it reports this error but if I take out the assignment to variable "choice" that it works just fine.
I rewrote the function using a separate variable and this time it works perfectly:
Notice the indexing variables in the "if" statement and the assignment to "choice" are different.

I use the following code on a form (which works)
function SubmitDocument(){
var frm=document.forms[0];
if(frm.QuestionSeventeen.value=="") {
alert("Please enter your postcode");
window.document.forms[0].QuestionSeventeen.focus();
return false;
}
else
document.forms[0].submit();
}
This is fine, because QuestionSeventeen is a text field. However, I have a number of radio and checkbox values on my form which I need to make sure are not NULL.
I want to make this more efficient and not use LOTS of these nested IFs.
i.e., does anyone have any code that will check firstly specified text fields, then radio buttons, then checkboxes in a more efficient manner?
so.... somthing like this process is what I want to achieve
Function validate()
- make array of text fields, loop through them checking not null THEN
- make array of checkbox fields, loop through them checking not null THEN
- make array of radio button fields, loop through them checking not null THEN
If all OK, save doc otherwise alert that field needs to be filled in then gocus on that field END FUNCTION

I am using ASP validators and I have a contact form. I want to be able to have a phone and email radio button group. The email textbox also has a RegularExpressionValidatorIf the phone item is selected then I want the validation to be enabled on the phone text box making it mandatory while the email text box isn't, and if they choose the email as the contact it will be reversed.I want to be able to do this without having to do a postback.I already have the logic on the code behind and the enquiry object.also I am fairly new to javascript so I have been using mostly jQuery as easier to implement
