Disabling Form Elements - Dropdown To Be Switched Off / Disabled If They Have Radio Button And Vice Versa
Sep 26, 2010
I have a Java form where I need to be able to switch a drop down with a text box using Javascript. The change would be made depending on the radio button choice the user makes. The drop down is the default form element and radio button A is checked by default. So when the user clicks radio button B the text box should appear and if they change their mind and select radio button A the drop down should come back.
Whats making this a little tricky is that I'm doing my form validation using Java via the form element name. So these two will have the same name. I need for the drop down to be switched off/disabled if they have radio button B and vice versa. Is all this doable using javascript?

I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: [URL]. Here is my script:
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus
[Code]....

I need a Javascript that can process two math formulas to convert Estimated Average Glucose to HbA1c and vice versa. The formulas are as follows:
(28.7 x A1C) - 46.7 = eAG
(46.7 + eAG) / 28.7 = A1c
It could be a two function javascript or two separate javascripts, I am not that particular as long as it does what I need it to do. The way I would like to see it work is you type the number you have into a field, and press a button to convert it. If it was a two function javascript you would have to select the conversion type you want do first.

Is it possible to access javascript variables in an iframe src page from the parent page, or vice versa. How do you do this? What about the DOM?

I have a form that disables the radio options after choosing one and pressing a confirm selection button. Does the disabled attribute affect the value submitted?

I have a set of radio buttons on my pricing page:
And a corresponding text_field input element div I'd like to display based on which radio button the user selects:
When the page loads, I'd like to see:
When the user clicks on a (different) radio button, or clicks one for the first time, I'd like whichever div is currently showing to be hidden, and the newly selected one to be shown.
Right now I have jQuery code at the bottom of my page that looks like this:
For each of the four options.
When the page loads, the correct div is shown, and when I select a new button, the new div is shown, but the already showing one isn't hidden.
I've read some posts that suggest using change() instead of click(), but others indicate that's problematic in IE.

I have set up a JSFiddle to demonstrate what is happening:[URL]... Basically if All content types is checked already and is clicked when checked then searchAjax should not be invoked. It currently invokes the function. When it is not checked and clicked then it should behave as it is now (disable sibling radio button and uncheck all associated checkboxes).

var formEls = document.forms[0].elements[];
for (i=0; i< formEls.length; i++) {
document.forms[0].elements[i].disabled = true;

I would like to loop through elements that are NOT disabled. So far my code is:
$("#addlivestock :input").each(function(){
if($(this).find().attr('disabled','disabled'))
{
var getAttr = $(this).attr("name");
[Code]....
When I click a button that code fires. When that code fires all the elements that aren't disabled get disabled. My code does NOT work as expected and I found the problem, which is if($(this).find().attr('disabled','disabled')). how to loop through form elements that are NOT disabled.

I'm currently working on a form for my site and would like to do something
that I've seen many times on other sites. I would like to make a particular
form element enabled or disabled depending on whether another requisite form
radio button is checked. I tried this:
<input type="radio" name="yesorno" id="yes"
onClick="document.getElementById('metoo').disabled = 'false'">
<br>
<input type="checkbox" id="metoo" disabled="true">
<br>
<br>
<input type="radio" name="yesorno" id="no">
but it doesn't work--I can't figure out why.

I am writing a ASP.NET UserControl and I am trying to incorporate JQuery into this. The control is a simple form with a few input fields (text, checkbox, select, radio). The first element in the form is a checkbox. Upon clicking this checkbox I want the all the input elements in the form (except the checkbox control itself) to be enable/disable. I tried writing some of this code but my solution was not getting me anywhere. Below is the ASP.NET form code.

I've got a form inside a PHP script that posts to itself, does some
processing on the PHP side, and if it looks good, PHP sends a HEADER
command that redirects the user out. All was fine until I added a
button disabler onSubmit to keep users from submitting twice. Now the
form disables the button as requested but just refreshes the page... it
doesn't get to the HEADER command.
Any idea what the problem might be?
<script language="Javascript">
function disable(theForm) {
theForm.send_email.disabled = true
return (true)
}
</script>
<form action="<?=$_SERVER[PHP_SELF]?t=$_GET[t]?>" method=post name=form
onSubmit="return disable(this)">

I have this markup:
[Code]...
There are two radio buttons, sometimes one will be disabled, other times the other will be disabled. I would like to make a script that: First: Changes the color of surrounding text of the disabled radio button to the color grey. Second: Checks the other radio button.
This was my plan: I would make a script that: First: Removes all the current classes and add the class "greyed_out" (or better: change only the color of) the parent element, all siblings and children of siblings (if any) of the radio button that is disabled at that time.Second: Sets the attribute "checked to the other radio button". I made a script, but when I set the bottom radio button to disabled the script doesn't work:

I'm trying to set up a form such that the Submit button will be disabled until a set of values has been set in the form.I have latitude and longitude text input elements (named coordPointLat and coordPointLon respectively) and they are not acting as I would expect.With coordPointLat set to 354104 and coordPointLon empty the following test always falls down to the line where the Submit button gets enabled.

So I have a dropdown box and when a certain option is pressed will show other fields... if not they stay hidden. However, I also need it to check a radio button that should remain showing.
Right now I have
<script type="text/javascript">
$(document).ready(function(){
$(".dnuHide").hide();
$(".dnuHide input").attr("disabled","disabled");
// If option Other is selected for institution type, show text field for Other
$("#region").change(function() {
var val = $(this).val();
$(".dnuHide input").attr("disabled",(val=="DNU")?"":"disabled");
(val=="DNU")?$(".dnuHide").show():$(".dnuHide").hide()
});
});
</script>
How would I modify that so I can also have ()Option 1 (*)Option 2 (already checked) change to (*)Option 1 ()Option 2

On my page I have 3 radio buttons:
"FIRST"
"AFTER"
"LAST"
Beside the "After" radio button I have a dropdown menu:
"AFTER_LIST"
What I'm wondering is how to make the "After" radio either get it's value from /or make it link to the "After_List"'s value.
Also I was wondering how to make the "After_List" values only acessable when the "After" radio is selected.

Anyhow... I've written some nice clean functions to do my form validation with (wow, really enjoy writting code in JavaScript!) - thing is that's puzzling me... I'm using 'onsubmit(return fnc_FormValidation(this)' in my form tag...
But what if the user has JavaScript turned off? My form validation won't work at all will it?
How do I get around this problem? Should I just use PHP validation, like I have been for years anyhow..

I've got a JQuery Mobile form working across multiple "pages", even though it is a single HTML file.This is done by placing the opening form tag before the <div data-role="page"id="screen1"> tag, and closing it after the final losing page div tag. Works great.Currently the form validation is properly flagging each field as the user leaves it.The only trouble I am having is making the continue button at the bottom of each screen disabled until the visible invalid fields pass validation.Here's the simplified version of the code:
<!DOCTYPE HTML>
<html>
<head>

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):
