JQuery :: Can't Remove Pre-checked Radio/checkbox Attributes
Jun 2, 2010
if you have a form with pre-checked radio or checkbox elements it is not possible to remove the checked states neither with
$('#id').attr('checked', false);
//or
$('#id').attr('checked', '');
nor with
$('#id').removeAttr('checked');
If the elements are not pre-checked but you check them with mouse click - it works as expected. Background: I have a search form which is prefilled based on previous selections and queries but I need a reset button to clear all checkboxes and fields.

I was under the impression, via W3Schools that 'checked' is only a property of radio/checkbox input objects. I was trying out this code that loops through several different types of inputs:
Code:
//start loop
var elem = theInput[i]; //grab the input
if('checked' in elem && !elem.checked) { continue; }
//...do some other stuff
//end loop
As you can tell, I want to skip all radio/checkbox inputs that aren't checked because they are meaningless in my circumstance.....the problem is, it skips over EVERYTHING (that isn't checked) regardless of if it's a hidden input, text input, password input, etc..... I did a quick test:

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've added some functionality to a checkbox. So that when the checkbox is checked it will display a div, when unchecked it will hide the div. This is working fine except when the checkbox is clicked, it doesn't display the checkmark in it. And when the form is submitted, the checkbox is unchecked.
Checkbox
<input
type
="checkbox"

Im trying to delete an element if the checkbox inside it is checked.
if($j(this).find('input[id^="checkbox"]:checked').length == 1)
{
var parts = $j('input[id^="checkbox"]:checked').attr('id').split('-');
$j('input[id^="checkbox"]:checked').each(function(){
$j('dl#row-'+parts[1]).remove();
});
});
however it only removes the last element.

This function is getting called as it should. the line "if ($("lumode").attr('checked'))" is not detecting the state of the checkbox properly. It always returns false so mode never gets set to 'all'. (#lumodestate is a button I am using to test the function).
$(function(){
$("#lumode").click(function(){
mode = '';

I have a simple form which I am running a validation on a single text box (as shown below, adapted from the milk example).
$(document).ready(function() {
// validate signup form on keyup and submit
var validator = $("#updateModules").validate({
rules: {
guestbookContact: {
required: true,
email: true
},
},
// the errorPlacement has to take the table layout into account
errorPlacement: function(error, element) {
if ( element.is(":radio") )
error.appendTo( element.parent().next().next() );
else if ( element.is(":checkbox") )
error.appendTo ( element.next() );
else
error.appendTo( element.parent().next() );
},
// specifying a submitHandler prevents the default submit, good for the demo
submitHandler: function() {
form.submit();
},
// set this class to error-labels to indicate valid fields
success: function(label) {
// set as text for IE
label.html(" ").addClass("checked");
}});
Now I only want to validate the text box if the checkbox "requireEmail" is checked. Is there an easy way to do this?

$("#activey").prop("checked", true);

I have a form with x questions (the questions come from a database, so the number of questions is variable). Each question needs to be answered with a number form 1 to 10, I do this using radio buttons. The name if those radio buttons is "name" followed by the id of the question in the database. Because the name is variable and the number of questions is variable, how can I check if all the questions are answered i.e. one radio button must be checked for every group of radio buttons.

I'm having a bit of trouble getting the checked radio values from my form so I can submit them via AJAX. The main problem is, I do not know what the name is going to be, and there could be any number of them. Here is a basic example of the HTML code (It is dynamically generated).
<form id="addnew"><input type="hidden" name="clientid" value="1" />
<table class="clientareatable" align="center" cellspacing="1">
<tr class="clientareatableactive">
<td>This is a test question 1</td>

I'm trying to reset a form so that no radio buttons are selected. The code works in Firefox 3.5.7, Chrome 3, and Safari 4.0.3. However, in IE 8 only the 1st radio button is correctly cleared. If I check the 2nd radio button and click the clear button, the 2nd radio button IS NOT cleared. The following HTML should reproduce the issue. Can others reproduce this? [code]...

I'm trying to figure out if it makes sense to use jQuery to do the following. I have a form with several checkboxes. If one particular checkbox is checked, I'd like a required dropdown field to appear. Is this something fairly straightforward to do with jQuery?

Im fairly new to JQuery and need some help. Googling failed me :o have a web page that initially auto refreshes every 30 secs and has a bunch of checkboxes that are initially unchecked. I am trying to make it so that if at least one of those boxes it checked the page stops auto refreshing (without reloading the page, preferably). Is this at all possible? I am using Perl to generate the html.
My auto refresh is in the header, but im open to sticking it somewhere else, as long as it doesnt create crazy memory consumption that i've read about on these forums:<head

I have a fairly straightforward form with validation on a number of fields, all of which is working fine.
I have credit card information fields being validated only if a Payment Method radio button is set to 'Visa' or 'Mastercard', and this is also working correctly.
<input name="payment_method" value="visa" type="radio" class="radio payment_method">Visa
<input name="payment_method" value="mastercard" type="radio" class="radio payment_method">Mastercard
[Code].....
These input names don't appear anywhere else in the HTML document and they're not validated fields, however if either of them are checked, the conditional credit card validation no longer fires, although the remaining non-conditional validation on the page continues to work as normal.
EDIT: It would appear that if *any* of the radio buttons on the form are selected, the payment information validation is disabled.
I'm at a loss as to explain what's happening. I'm leaning towardsinput[#payment_method]:checked syntax, and specifically the :checked syntax as potentially causing the issue
