Ignore value radiobuttons - iCheck - javascript

I try this way for get a value from radiobuttons (iCheck), but all the time only return the value from the first radio, ignoring the remaining. The theory says that the code is fine, even so it returns badly.
Radio box, get the checked value [iCheck]
My code:
<div class="step row">
<div class="col-md-10">
<h3>YYYYYY.</h3>
<ul class="data-list-2">
<li><input name="p1" id="p1" type="radio" class="required check_radio" value="1"><label>Yes</label></li>
<li><input name="p1" id="p1" type="radio" class="required check_radio" value="0"><label>No</label></li>
<li><input name="p1" id="p1" type="radio" class="required check_radio" value="2"><label>Meybe</label></li>
</ul>
</div>
</div>
<!-- end step -->
My method for get value:
$(document).ready(function() {
$('#p1').on('ifChecked', function(event) { //try ifClicked - ifToggled
alert($(this).val()); // alert value
});
});
All the time return value 1 even when another option is selected.
Please help, I try all the night different ways but doesn't work ;(

I'm not sure how you are generating the ids for your radio buttons, but the id property should always be unique, since you want the same event handling on your radio buttons, just use the class so that it attaches the event to all your radio buttons which belong to that class, then you don't have to add events for each individual id:
So instead of this:
//If you did it this way, you'd have to have one of these blocks for each
//unique id belonging to a radio button
$('#p1').on('ifChecked', function(event){ //try ifClicked - ifToggled
alert($(this).val()); // alert value
});
Change it to this:
//Use the class instead so that the same event handling can be added to all radio
//buttons in one block of code
$('.required.check_radio').on('ifChecked', function(event){ //try ifClicked - ifToggled
alert($(this).val()); // alert value
});

Selected value of Radio Button doesn't change

In the view, I have these two radio buttons:
#Html.RadioButtonFor(c => c.CampaignType, "Exclusive")<label>Exclusive</label>
#Html.RadioButtonFor(c => c.CampaignType, "Shared")<label>Shared</label>
The value for Model.CampaignType is set in the controller before the page loads. All of this works fine. If Exclusive is what's saved in the DB, then we get this rendered in the HTML:
<input checked="checked" id="CampaignType" name="CampaignType" type="radio" value="Exclusive"><label>Exclusive</label>
<input id="CampaignType" name="CampaignType" type="radio" value="Shared"><label>Shared</label>
So far, all's well.
But, inside an onclick() event for a button, if I do this:
var values =
{
"CampaignType": $('#CampaignType').val()
}
alert(values.CampaignType);
The alert always comes up as `Exclusive', even if I have changed the selection to 'Shared'.
What do I need to do so that values.CampaignType reflects the what is selected on the page, and not what was set when the page was loaded?
So you can do start with these:
Remove the invalid ids - multiple ids are invalid in CSS. For getting the value of the checked radio button you can use:
$('input[name=CampaignType]:checked').val()
or
$('input[type=radio]:checked').val()
For the label to work you have to link it with the corresponding radio button using the for attribute.
See demo below:
function submit() {
var values = {
"CampaignType": $('input[name=CampaignType]:checked').val()
}
console.log(values.CampaignType);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input checked="checked" id="CampaignType1" name="CampaignType" type="radio" value="Exclusive">
<label for="CampaignType1">Exclusive</label>
<input id="CampaignType2" name="CampaignType" type="radio" value="Shared">
<label for="CampaignType2">Shared</label>
<br/>
<button onclick="submit()">click here</button>
All the best!

Get output of .change() function in .click() function

I have two radio buttons which both have values. When one is selected, and a button/link is clicked, the value of the selected radio button needs to be outputted to a text box.
Here is my HTML:
<form class="discount-choice" method="post" action="#">
<ul>
<li>
<input type="radio" value="1" name="discount" id="1-month" class="discount-checkbox" />
<label for="1-month">1 Month - no discount</label>
</li>
<li>
<input type="radio" value="0.95" name="discount" id="4-months" class="discount-checkbox" />
<label for="4-months">4 months - 5% discount</label>
</li>
</ul>
Get Result
<input type="text" class="result" />
</form>
and my JavaScript (jQuery):
var discount = $(".discount-checkbox").on("click", function () {
return this.value;
});
$(".get-result").on("click", function() {
$(".result").attr("value", discount);
});
When I click the button (after having selected a radio button), I just get [object Object] in the text box.
I'm not sure of the syntax for setting a variable to be a jQuery function so this is likely where I am going wrong. If anyone could give me some guidance that would be awesome.
Thank you for any help :)
discount is set to the jQuery object returned by $(".discount-checkbox"). You need to bind a click handler that updates a variable:
var discount = 0;
$(".discount-checkbox").on("click", function () {
discount = this.value;
});
Use this:
$(".get-result").on("click", function(e) {
e.preventDefault();
$(".result").val( $('.discount-checkbox:checked').val() );
});
You do not need the click handler on the checkbox as #billyonecan has mentioned in the comments.
And ... if you really need to attach an event handler to the checkboxes, that would be a change event handler instead of click.
Try This Code:
var discount;
$(".discount-checkbox").on("click", function () {
discount= this.value;
});
$(".get-result").on("click", function() {
$(".result").attr("value", discount);
});
no need of discount-checkbox click event
$(".get-result").on("click", function() {
var discount = $(".discount-checkbox:checked").val();
$(".result").val(discount);
});

Javascript/jQuery: search within object

I have the following code.
<div class="days">
<input name="days-select" type="radio" value="Mon" > Mon </input>
<br>
<input name="days-select" type="radio" value="Tue" > Tue </input>
</div>
<script>
$(document).ready(function() {
radiobtn = $('.days');
radiobtn.find('value="Tue"').prop('checked', 'checked');
});
</script>
Basically, I need a two-stage search. First, find the group of radio buttons, then set one of them as checked. HOWEVER, I do not want to combine these two steps into one. Thanks for the hint.
BTW, since I am new to Javascript I would like to ask how to debug this code. For example, single-step through the script, and after "radiobtn = $('.days');" check whether "radiobtn" is assigned correctly etc. Thanks again.
HTML
<div class="days">
<input id="dayMonday" name="days-select" type="radio" value="Mon">
<label for="dayMonday">Monday</label>
<br>
<input id="dayTuesday" name="days-select" type="radio" value="Tue">
<label for="dayTuesday">Tuesday</label>
</div>
script
$(document).ready(function () {
//your .days selector is actually getting the div and not the radio button
var div = $('.days');
//maybe here you want to do some things with the div...
//...
var radiobtn = div.find('input[value="Tue"]');
//maybe here you want to do some things with the radio button...
//...
//now you have the correct element...
radiobtn.prop('checked', true);
//F12 in Chrome to see the console
console.log(radiobtn);
//notice the selector property returns: .days input[value="Tue"]
console.log(radiobtn.selector);
//so you could just do this all in one line:
$('.days input[value="Tue"]').prop('checked', true);
//see last commented line regarding this next line...
//$('.days input[value="Tue"]').click(
// function(){ console.log("you clicked Tuesday");});
//Note: you could do this:
//radiobtn.click();
//... or this:
//$('.days input[value="Tue"]').click();
//but it also fires the click event which is why you would see
//"you clicked Tuesday" in the console with the above line uncommented
});
Here's a fiddle.

Enabling and disabling all the child elements

I have this issue with enabling and disabling section of fields if other section of fields have specific value.
Consider jsfiddle for html code.
Conditions are
If all the fields of partA are selected as No, then enable partB.
If all the fields of partB are selected as No, then enable partC.
Try 1
First I tried disable elements of PartB and PartC which did not work.
$(function () {
$('.group').attr('name','partB').find('input').attr('disable', true);
$('.group').attr('name','partC').find('input').attr('disable', true);
});
I am not sure how would make sure if all the child elements are selected as No in a group div.
jsBin demo
Having this HTML:
<div class="group" id="partA">
<span> PART A</span><br/>
Option 1
<input type="radio" name="optionsRadios1" value="option1"/>Yes
<input type="radio" name="optionsRadios1" value="option2"/>No
<br />
Option 2
<input type="radio" name="optionsRadios2" value="option1"/>Yes
<input type="radio" name="optionsRadios2" value="option2"/>No
</div>
jQ:
$(function () {
$('#partB, #partC').find('input').prop('disabled', true);
function testChecked(){
var $par = $(this).closest('.group');
var $rad2 = $par.find('[value="option2"]');
var allNo = $rad2.filter(':checked').length == $rad2.length;
$par.next('.group').find(':radio').prop('disabled', !allNo);
if(!allNo){
$par.nextAll('.group').find(':radio').prop({'disabled':true, 'checked':false});
}
}
$('.group :radio').change(testChecked);
});
The above will work also for more than 2 radio groups per .group
Your errors:
"disable", "true" should be "disabled", "true"
<label> can control only one inner element (so I removed it.)
<div> afaik is not supposed to have a name attribute (so I assigned an ID)

Knockout does not recognize manually click

Here is sample http://jsfiddle.net/HhXGH/57/
I am clicking radio button by jquery but knockout.js does not recognize it.Still it shows first clicked value.
<p>Send me spam: <input type="checkbox" data-bind="checked: wantsSpam" /></p>
<div data-bind="visible: wantsSpam">
Preferred flavor of spam:
<div><input type="radio" name="flavorGroup" value="cherry" data-bind="checked: spamFlavor" /> Cherry</div>
<div><input type="radio" name="flavorGroup" value="almond" data-bind="checked: spamFlavor" /> Almond</div>
<div><input type="radio" name="flavorGroup" value="msg" data-bind="checked: spamFlavor" /> Monosodium Glutamate</div>
</div>
var viewModel = {
wantsSpam: ko.observable(true),
spamFlavor: ko.observable('cherry')
};
ko.applyBindings(viewModel);
$(':radio:last').click();
alert(viewModel.spamFlavor())
This because Knockout is subscribing to the click events of checked radio/checkbox elements only. If you checkout the binding handler code for checked. It does this.
var updateHandler = function() {
var valueToWrite;
if (element.type == "checkbox") {
valueToWrite = element.checked;
} else if ((element.type == "radio") && (element.checked)) {
valueToWrite = element.value;
} else {
return; // "checked" binding only
responds to checkboxes and selected radio buttons
}
So in order to get your code to work do this.
$(':radio:last').prop('checked', true).click();
However if the goal is to check the last value, why not just do
viewModel.spamFlavor("msg");
This would achieve the same result.
Hope this helps.
Adding $(':radio:last').attr('checked', true); in addition to triggering click makes it work for me:
http://jsfiddle.net/jearles/HhXGH/61/
I have two different jsFiddles since I'm not sure exactly what your after.
The first jsFiddle will respond via alert when the last radio button is manually clicked.
The second jsFiddle is your posted /57/ jsFiddle without the alert.
Using an alert or console.log with a function will actually invoke that function. That said, after you have manually set the .click() to the last radio button, it's inadvertently reset back to cherry since that's the default value.
RE-EDIT: The second jsFiddle now includes alert written in syntax that doesn't invoke the function & now uses shorted markup.
