Validate Radio Buttons In A Html Form With Script?
Mar 24, 2011
I'm new to javascript as well as to this forum, Im coming here for first class
I have a html form that uses javascript for validation, this is an assignment that consists of a form that sells hard drives from three different manufacturers, more specifically the part im stuck on is where if a manufacturer hoes have a number in the number of drives textbox, javascript needs to check to see that one of the radio buttons in that row is checked, if no radio button is checked
an alert is displayed, however when I do select a radio button I still get the alert I used a "if...else if...else" construction but my logic is not well structured and thereby I get those problems, I have included the code down below if anyone is interested in helping a newbie out code...

I am having an issue with a simple problem but can't figure it out. I have multiple radio button questions and I want to verify they have each one checked on submitting the form.
Below is my code and it works for the first question but not the second. The radios are named 1 and 2
Code:
$('#section1').click(function() {
if (!$("input[@name='1']:checked").val()) {
alert('Please Answer Question 1.');
[Code]....

Here is a suggestion for the documentation. It can be added to General_Guidelines. This is important because, for me at least, I had to figure it out on my own how to deal with radio buttons. A suggestion in the documentation would have saved me a chunk of time. [URL] Error Placement for Radio Buttons (and perhaps checkboxes). If the default placement of the error message doesn't work for your radio buttons, here is a suggestion.
First, here is my customized message, in jQuery("#frm").validate. Notice the <br> tag.
messages: {
x_gender: " Select One<br/>",
},
Also in the validate function.
// the errorPlacement has to take the table layout into account
// "error" is the error message, as a jQuery object. The element is the first of the group of radio inputs.
errorPlacement: function(error, element) {
if ( element.is(":radio") ) {
error.prependTo( element.parent() );
} else { // This is the default behavior of the script
error.insertAfter( element );
}}
I propose this as the default method for radio buttons. And perhaps checkboxes. This way, in my form html at least, the error message appears on a line just above the first radio button. Otherwise, it appeared immediately to the right of the button, between the button and the label.

I'm trying to create a questionnaire style series of radio buttons which are hidden and then a different set of radio buttons displayed depending on the previous answer. eg
Q1 Is it a man? (if select yes then display)
Q2 Is he called John? (if no then display)
Q3 Is he called Gary? and so on...
I've been testing using the code below but wondered if anyone had any ideas on how this could be done easily?

In an html form, I want a certain field to be invisible when "no" is checked and visible when "yes" is checked.
This is my code:
html:
<form action="pageName.html" method="post" name="formName">
Question?
<input name="radioBool" type="radio" value="1" onchange="dispField('textInput');" />yes
[Code]....
This seems to work perfectly across all browsers except for IE (latest version).
In IE the only problem is that the radio buttons have to lose focus before the span will change to visible. I would like the "specify" field to display immediately after the radio button changes to yes, rather than waiting for the buttons to lose focus.

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 am using IE to hide sections of a form. When I display the first
section (name='ea'), the form widgets are not clickable in IE nor do
they accept focus. When I display the 3rd section (name='ec'), the
items in all sections become clickable/accept focus. Has anyone ever
seen anything like this? Code:

I have 3 radio buttons with the same name ("myradio"). The value of each is a different URL (e.g. value="[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. Is there any way of doing this using Jquery?

I am creating a form for a registration that asks the participant if they have completed pre-requisite training. There are three questions they are asked. When they click yes, the text box for the requested information is enabled, when they click no, they get a warning that they need to register first.
Here is the javascript
The first one works fine (the SERE training question), however, the second one does not function at all. What am I missing to enable the second question to function like the first.

I have a form which has two radio buttons at the beginning which show and hide fields depending on what button is clicked:
I want to adapt this js and html code so that when the page loads it checks whether one of the two radio buttons is clicked and depending on that it displays/hides the divs which are declared in the current function, at the moment it performs this when the user clicks one of the radio buttons but I want to perform it when the page is loaded and also when the user first enters the page I want the yes radio button to be selected and obviously show/hide

<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>

I have a form with a search field that I want to search two different databases depending on which radio button is selected. Below is the form I have for searching our library's online catalog.

I'm trying to get my form to show and hide various divs with radio buttons. There are multiple options in the second box of my example. When a user selects the first option, more input boxes come up. Perfect, that's what I want. However, if they decide they didn't mean to click that option and instead wanted another option, the original part that popped up doesn't disappear. I cannot figure out how to make this happen.

I am trying to make an option calculator for my site. The user will click on various radio buttons and checkboxes, before pressing the calculate button. The button will then add up all the values to show the overall figure. The code shown below is what I have so far.
Code:
function calcMe(){
for (var i=0; i < document.form.radio.length; i++){
if (document.form.radio[i].checked){
var rad_val = document.form.radio[i].value;
}} if (document.form.radio1.checked) {
document.form.result.value = rad_val;
} if (document.form.radio2.checked) { .....
The first javascript is to show the value of the radio button with the textfield attached - when the user puts a number in the textfield, it will update the value of the radio button. The second javascript is to check the document for the clicked radio buttons and checkboxes. It then adds up all the clicked values to show the answer. The problem that I am having is to put these two javascripts together so as the radio button is updated with the text field value as well as adding up all the clicked values.
