Validate Radio Button Options?
Nov 3, 2010
I already have a form that validates all the fields I want via javascript but I cannot figure out how to validate the radio buttons. How can I check that an option has been selected?
Currently, I am checking that a checkbox is checked like this:
Code:
else if (!f.confirm.checked)
{
//Need to confirm
alert('You must check the confirm box to continue')
[Code]....
I've read some other posts and methods for radio buttons but have been unable to get them to work.

I have some code I use for form validation but can't figure out how to make it work for a radio button. The radio button:
<INPUT type="Radio" NAME="BestWayToContact" VALUE='Call Me'>phone
<INPUT type="Radio" NAME="BestWayToContact" VALUE='By Email'>e-mail
Validation code that works for text fields
if ((document.form.phone.value == "Phone Number") ||
(document.form.phone.value == "")) {
missinginfo += "
- Phone Number";
[Code]....

I have a list of radio buttons. Each radio button has a dynamic name. Is there a way to check if they are all selected? Because most radio validation scripts uses a static name. code...

I want to achieve when first radio button is pressed form doesn't validate and when second radio button is pressed it does validate.I tried do it this way by assigning var to radio buttons an then checking that var on form submit but something is wrong:
<form action="" method="post" name="Anketa" id="Anketa" style="margin:0px;" onSubmit="if (os_podaci=1) {MM_validateForm('ime','','R','e-mail','','RisEmail');return document.MM_returnValue}">
<input name="dali_zeli[]" type="radio" id="Radio1" value="ne" onClick="window.document.getElementById('OsobniPodaci').style.display='none' var os_podaci=0; ">
<input name="dali_zeli[]" type="radio" id="Radio2" value="da" onClick="window.document.getElementById('OsobniPodaci').style.display='block' var os_podaci=1;" checked>
</form>

I'm trying to validate that a user checks a radio button.
The trick is, depending on a search the user does there could be from 0-20+ buttons they could end up with. This code I have so far works if there is 0, or more than 1 button. However if there is only 1 button and they select it, it will bring up the alert that none are checked. Here is the code
Code:
function validatebutton()
{
var radio_choice = false;

I have been trying to validate both the Radio button and the Select Option box, but it does not work. It didn't show error, only din't do the way I want.I like to validate like this:If a user check "Yes" on this Radio button, then the OPTION box is disabled and no need to validate. However,when I tried the JS code below, the pop up window kept asking for a user to enter the "Seller" name.I combined both together as:
if (document.frmSelect.sellers.disabled=false && document.frmSelect.sellers.selectedIndex==""
html code

I have a form that has 4 "required fields" that validate using JS. I am now trying to add a 5th "required field" (the difference is that this field is a "radio button input as opposed to a text input).
I have it working so that when the 1st radio button is selected, the form will go through. However, when the 2nd radio button is selected, it comes up with the "please fill in all required fields" error.
Here is the JS I have so far:
HTML Code:
I tried adding the 2nd radio button value like this:
HTML Code:
(document.indiv_reg.skill[0].checked =="") || (document.indiv_reg.skill[1].checked =="") But when I do that, then even when the 1st radio button is selected it comes up with the "please fill out all required fields error".
PHP Code:

I am a PHP programmer and new to Javascript and jQuery and I have tried about 20 examples/tutorials and cannot seem to get even close to what I want.I have a form (PHP/MySQL) with a list of subjects I got from my database, and then create a set of radio buttons from that list. And based on what radio button they select, I need to pass that variable to a div (at least that's what I want to use) and then show a list of videos that match the radio buttons value. I don't care if its a get or post or other.I tried to use GET or POST so I can use that value for my PHP/MySQL lists.I am open to any suggestions/tutorials, etc.

Need a script which selects a second radio button when the first radio button in the pair is clicked with the second button greyed/disable but still displaying the selection.
(Hoping to keep the input 'name' the same too if possible - maybe they can be differentiate by 'id' for the script ?)

I'm trying to write a shopping basket in ASP and I need to force the user to choose one or more "Option" radio button(s) before allowing the form to submit.
For example:
<input type="radio" name="option1" value="1">Red
<input type="radio" name="option1" value="2">Blue
<input type="radio" name="option1" value="3">Green
<input type="radio" name="option2" value="1">Small
<input type="radio" name="option2" value="2">Medium
<input type="radio" name="option2" value="3">Large
I want the user to HAVE to choose a colour and size from the above options before the form will submit or else they will get a Javascript popup message asking them to make a choice. (There may also be more/less options so it needs to be dynamic)
I know ASP inside out but very little knowledge of Javascript so once i have the basics of how to do it I can make the code dynamic. There will be a maximum of 5 "Options" for a product and a maximum of 6 choices for each Option.

I have a set of radio buttons each with an onclick event that has a numeric value. When the button is clicked an input box called "Total" is updated with the new value. The problem I'm having is that if a radio button is checked and one clicks on it again then the onclick event is triggered.
Is there any way to prevent the onclick event from triggering if the radio button is already checked?

I have 3 radio buttons with the same name ("myradio"). The value of each is a different URL (eg. value="http:[url]...)I have a link underneath these (<a href="#">Send</a>). I would like the selected radio button's value to be inserted into the href of the link, and if the user selects a different radio button that this changes.

I am trying to produce a web form to allow wedding guests to RSVP. The form allows them to enter a name and select from a radio button whether they will be attending or not. If they select the "yes" radio button then a further pair of radio buttons are displayed for their meal preference.
They can then click a submit button or they can click another button to add another line for another guest which operates in exactly the same way. I've almost got this working, but it seems that the checkbox change handler is lost for the current guest when a new guest is added and the checkbox value is reset. I've got a feeling I'm doing something stupid but can't for the life of me figure out what.
Code (source file (renamed to .txt) also attached as I'm not sure the pasted code is too clear):

I have it set up so that there are three frames (frames and the use of javascript are encourage for practice) "bar" on the left with navigational options, "main" in the center where the body of the drill is presented, and "feedback" along the bottom where the feedback will appear.
My issue is that I have everything working except the form! I'm not sure how to make it so that upon clicking the submit button the feedback is presented in the "feedback" frame. This was suggested to me but isn't working, maybe I have a mistake somewhere? Or is there another way I can do this?
