Checking For A Single Or Multiple Radio Buttons?
Feb 19, 2010
I have the following javascript code:
Code JavaScript:
for (var i=0; i < myRadio.length; i++) {
if (myRadio[i].checked) {
myChecked = 1;
[Code]....
This works fine when I have more than 1 radio button. However for just a single radio button it does not work. I don't know how many radio buttons I will have since they are being created from a mysql query.
I'm very bad with javascript, so how should I amend the code so that it also works with only one radio button? I just need to check if they are trying to submit the form without selecting any radio buttons.

The code I wrote is showing three random results from the database and each result gets three options to choose from (spoon, fork, knife). What I need to figure out is a way to make sure each image thats showing up gets one vote - and the person cannot vote on the same answer for pic2 and pic3 (ie: if they vote "spoon" for pic1, I need it to give a "please vote again" message if they click the same answer for pic2 or pic3).

I have a little checkbox that when checked is suppose to "check" a number of radio buttons.
Problem is I get a js error ("Object doesn't support this property or method") when I click the checkbox that calls my check all function.
HTML Code:
<tr bgcolor="#eeeeee" class="form_header">
<td align="center" valign="middle">Database</td>
<td align="center" valign="middle">Primary <input type="checkbox" name="checkPrimaryAll" onClick="checkPrimaryAll();" style="background-color: #EEEEEE;"></td> <--- This is the line in error
<td align="center" valign="middle">Backup <input type="checkbox" name="checkBackupAll" onClick="checkBackupAll();" style="background-color: #EEEEEE;"></td>
<td align="center" valign="middle">Remove <input type="checkbox" name="checkall" onClick="checkAll();" style="background-color: #EEEEEE;"></td>
<td align="center" valign="middle">Current DBA(s)</td>
</tr>
...
<script type="text/javascript">
function enableDisable(objectNme, myId)
{
var remCheck = document.getElementById(myId);
if(remCheck.checked == true)
{
eval("document.forms[0]." + objectNme + "[0].disabled = true;");
eval("document.forms[0]." + objectNme + "[1].disabled = true;");
}
else if(remCheck.checked == false)
{
eval("document.forms[0]." + objectNme + "[0].disabled = false;");
eval("document.forms[0]." + objectNme + "[1].disabled = false;");
}
else
{
alert("Error");
}
}
function checkAll()
{
var lng = document.AssociateDBAForm.remove_dba.length;
var select_all = document.AssociateDBAForm.checkall.checked;
var myForm = document.AssociateDBAForm;
var value;
for(var i = 0; i < lng; i++)
{
if(select_all == true)
{
myForm.remove_dba[i].checked = true;
myForm.checkall.title = "Unselect all rows";
value = myForm.remove_dba[i].value;
value = "ADD_" + value;
eval("myForm." + value + "[0].disabled = true;");
eval("myForm." + value + "[1].disabled = true;");
}
else if(select_all == false)
{
myForm.remove_dba[i].checked = false;
myForm.checkall.title = "Select all rows";
value = myForm.remove_dba[i].value;
value = "ADD_" + value;
eval("myForm." + value + "[0].disabled = false;");
eval("myForm." + value + "[1].disabled = false;");
}
}
}
function checkPrimaryAll() <--- This is the function it calls
{
var myForm = document.AssociateDBAForm;
alert("myForm " + myForm);
var lng = myForm.elements.length;
alert("lng " + lng);
var select_all = myForm.checkPrimaryAll.checked;
alert("select_all " + select_all);
for(var i = 0; i < lng; i++)
{
if(select_all == true)
{
myForm.checkPrimaryAll.checked = true;
myForm.checkPrimaryAll.title = "Unselect all rows";
thisElement = myForm.elements[i];
if(thisElement.name.substring(0, 4).equals("ADD_"))
{
thisElement[0].checked = false;
}
}
else if(select_all == false)
{
myForm.checkPrimaryAll.checked = false;
myForm.checkPrimaryAll.title = "Select all rows";
thisElement = myForm.elements[i];
if(thisElement.name.substring(0, 4).equals("ADD_"))
{
thisElement[0].checked = true;
}
}
}
}
</script>
As you can see I tried putting in alerts to try to debug, but it never hits them, even if it's the first line in the function.

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?

I have a form that has multiple radio button groups to allow the customer to build a custom product. I just want to figure out how to send all the CHECKED radio buttons (name="flexikits[1]", name="flexikits[2]", ect.. ) when the customer changes just one of the radio buttons. The goal of this is so I can update the price for the KIT right then.
I am easily able to set the onClick for each radio and have it send that particular radio button, just no clue how to send more.
Code:
function showPrice(str)
{
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
[Code].....
My best guess is there is javascript that I can replace for "this.value" that will send all the checked items in the form called "cart_view".

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 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 want my radio buttons to become submit buttons as well. So when a user clicks on a radio button it submits the action and refreshes the page accordingly. As of now using only using onclick="this.form.submit()" the page only refreshes with no change. Here is a copy of the entire form. It is a custom shipping options form (I did not create it).
<!-- Custom shipping form -->
<form action="" method="post" name="update_shipping">
<table width="300">
<tr>
<td><label>
<input <?php if (!(strcmp($_SESSION['shippingmethod'],"1"))) {echo "checked="checked"";} ?>

I am creating a website that uses columns (example) and I would like to be able to click left and right buttons to scroll horizontally one column at a time without the header and footer scrolling with the content.
I have tried using Scrollable and JCarousel but both require you to scroll through a set of list items. I need to be able to scroll 320px at a time. Is this possible?

Every time a radio button is pressed the system will grab certain data and send it via ajax to the server (providing a click path). In test I am loading the data to another div. I have been able to get everything BUT the value (I am able to capture the hidden fields and serialize all the data - and I am showing the current "date" in the test so I can verify that it's working).
How to getting the serialized button that was just clicked (or just the value and I can create the serialized data from that)
[sample code that works to a great degree at this point below.... ]

I'm checking for a radio button's value and hiding/showing a node based on that value, but it's not working right. Two radio buttons: one's value is yes, the other no. If you click on yes, the div shows up. When you click no, it hides, so that works.
But I have a list of checkboxes that also may or may not show that element based on the radio button selection, and it's this part that isn't working.
$('[name="'+obj.name+'"]:checkbox').click(function () {
aThroughS = ($('[name="'+obj.name+'"]:checkbox:lt(19):checked').length > 0),
tSelected = ($('[name="'+obj.name+'"]:checkbox:eq(19):checked').length > 0),
rSelected = ($('[name="'+obj.name+'"]:checkbox:eq(17):checked').length > 0),

I am using jquery with the cookie plugin and I have multiple image buttons that can hide/show multiple elements. My question is how can I add a cookie to this code to remember whether each separate element is opened or closed?
The code,
$(document).ready(function() {
// choose text for the show/hide link - can contain HTML (e.g. an image)
var showText='<div class="expanddown"></div>';
var hideText='<div class="expandup"></div>';
// initialise the visibility check
var is_visible = false;
// append show/hide links to the element directly preceding the element with a class of "toggle"
$('.toggle').prev().append('<a href="#" class="togglelink">'+hideText+'</a>');
// capture clicks on the toggle links
$('a.togglelink').click(function() {
// switch visibility
is_visible = !is_visible;
// change the link depending on whether the element is shown or hidden
$(this).html( (!is_visible) ? hideText : showText);
// toggle the display - uncomment the next line for a basic "accordion" style
//$('.toggle').hide();$('a.toggleLink').html(showText);
$(this).parent().next('.toggle').slideToggle('fast');
// return false so any link destination is not followed
return false;
});
});
HTML,
<a class="togglelink" href="#"></a>
<div class="toggle">
Content
</div>
