Unable to get radio group value via jquery - javascript

I have a radio group which is contains 2 radio buttons. This radio group created after an Ajax response. I want to get the value of the checked radio button but i am unable to do this. Here is my implementation, any help would be appriciated.
HTML:
Yes<input class='radioInput' id='g1Positive' type='radio' name='g1' value='YES'/>
No<input class='radioInput' id='g1Negative' type='radio' name='g1' value='NO'/>
JS:
$('#resultTable').on("click", ".editForm2", function(){
var isIengStuWork = $('input:radio[name=g1]:checked').val();
});

Hopefully this simple Fiddle is the answer
As you didn't post the html I just display the value in a div when a button is clicked
Html
<input [value][2]="first" type="radio" name="foo">First
<input value="second" type="radio" name="foo">Second
<input value="third" type="radio" name="foo">Third
<button id="show">Show</button>
<div id="result"></div>
JS
$("#show").click(function() {
var value = $('input[name=foo]:checked').val();
$('#result').html(value);
});
UPDATE
After your comment I wonder if you're element with id "resultTable" would be a dynamically loaded one as the radio buttons. In that case that binding wouldn't work.
You should be reference there an already existing element in the DOM, a static element let's say. Although you could still be dynamically loading the element with class "editForm2"
More information on http://api.jquery.com/on/
That would be something like this
$('#staticParentElement').on('click', '#dynamicChildElement', function(){ //whatever });
I have created this updated Fiddle. In it I mimic the ajax addition of elements to the DOM by displaying a button that adds content
In the first case I just add the content inside the table to an existing container, to which I bind the click event of the "show" button
So we add the radio buttons and the show button to a static #staticTable
<div id="staticTable"></div> <br/>
<button id="addStatic">Add dynamic content into static Table</button><br/>
$("#addStatic").click(function() {
$('#staticTable').append("Dynamic content into static table<br/>Yes<input class='radioInput' id='g1Positive' type='radio' name='g1' value='YES'/>No<input class='radioInput' id='g1Negative' type='radio' name='g1' value='NO'/><button class='show'>Show</button>");
});
And then we are able to bind the show button click like this
$("#staticTable").on('click', '.show', function() {
var value = $(':radio[name=g1]:checked').val();
$('#staticResult').html(value);
});
This works
But if we were adding to the DOM the "container" we are binding to, it wouldn't work. In the fiddle for example we inject a #dynamicTable inside a div
<div id="ContainerForDynamicTable"></div><br/>
<button id="addDynamic">Add dynamic Table</button><br/><br/>
$("#addDynamic").click(function() {
$('#ContainerForDynamicTable').append("Dynamic table<br/><div id='dynamicTable'>Yes<input class='radioInput' id='g1Positive'type='radio' name='g1' value='YES'/>No<input class='radioInput' id='g1Negative' type='radio'name='g1' value='NO'/></div><button class='show'>Show</button>");
});
and we try to bind the show button click selecting that #dynamicTable
$("#dynamicTable").on('click', '.show', function() {
var value = $(':radio[name=g1]:checked').val();
$('#dynamicResult').html(value);
});
This doesn't work
Notice that for making the last one we should find a static parent of the .show button, in this case the closest in the upwards tree would be #ContainerForDynamicTable (you can even go up until document although it would be more costly to find later the .show button)

Try this:
$('#resultTable').on("click", ".editForm2", function(){
var checked_ele = $('input[type="radio"][name="g1"]:checked');
$(checked_ele).each(function(){
// do stuff here
});
});

How can I check with JQuery if a checkbox is checked and if so add a class to the parent label?

I would like, on load of the page, to check if a checkbox is :checked Then if it is, add a class to the label. I currently have the following script but it doesn't work.
$(document).ready(function() {
$('input').is(':checked') {
$(this).parent('label').toggleClass('label--active');
});
});
My HTML is:
<label class="container-checkbox" for="checkOne">
<span class="checkbox-label">Option one</span>
<input type="checkbox" id="checkOne">
<span class="checkmark"></span>
</label>
I can not change the DOM order as these are custom checkboxes.
I guess you can use this:
$(document).ready(function() {
let checkboxone = document.getElementById('checkOne');
checkboxone.addEventListener('change',function() {
checkboxone.parentNode.classList.toggle('label--active');
});
});
How does is work?
Everytime when the checkbox is clicked, the class 'label--active' will be added / removed.

jQuery event for all radiobuttons affected by change of one [duplicate]

Is there an easy way to attach a "deselect" event on a radio button? It seems that the change event only fires when the button is selected.
HTML
<input type="radio" id="one" name="a" />
<input type="radio" id="two" name="a" />
JavaScript
$('#one').change(function() {
if(this.checked) {
// do something when selected
} else { // THIS WILL NEVER HAPPEN
// do something when deselected
}
});​

Why don't you simply create a custom event like, lets say, deselect and let it trigger on all the members of the clicked radio group except the element itself that was clicked? Its way easier to make use of the event handling API that jQuery provides that way.
HTML
<!-- First group of radio buttons -->
<label for="btn_red">Red:</label><input id="btn_red" type="radio" name="radio_btn" />
<label for="btn_blue">Blue:</label><input id="btn_blue" type="radio" name="radio_btn" />
<label for="btn_yellow">Yellow:</label><input id="btn_yellow" type="radio" name="radio_btn" />
<label for="btn_pink">Pink:</label><input id="btn_pink" type="radio" name="radio_btn" />
<hr />
<!-- Second group of radio buttons -->
<label for="btn_red_group2">Red 2:</label><input id="btn_red_group2" type="radio" name="radio_btn_group2" />
<label for="btn_blue_group2">Blue 2:</label><input id="btn_blue_group2" type="radio" name="radio_btn_group2" />
<label for="btn_yellow_group2">Yellow 2:</label><input id="btn_yellow_group2" type="radio" name="radio_btn_group2" />
<label for="btn_pink_group2">Pink 2:</label><input id="btn_pink_group2" type="radio" name="radio_btn_group2" />
jQuery
// Attaching click event handlers to all radio buttons...
$('input[type="radio"]').bind('click', function(){
// Processing only those that match the name attribute of the currently clicked button...
$('input[name="' + $(this).attr('name') + '"]').not($(this)).trigger('deselect'); // Every member of the current radio group except the clicked one...
});
$('input[type="radio"]').bind('deselect', function(){
console.log($(this));
})
​Deselection events will trigger only among members of the same radio group (elements that have the same name attribute).
jsFiddle solution
EDIT: In order to account for all possible placements of the attached label tag (wrapping the radio element or being attached through an id selector) it is perhaps better to use onchange event to trigger the handlers. Thanks to Faust for pointing that out.
$('input[type="radio"]').on('change', function(){
// ...
}
You can create a custom "deselect" event relatively painlessly, but as you've already discovered the standard change event is only triggered on the newly checked radio button, not on the previously checked one that has just been unchecked.
If you'd like to be able to say something like:
$("#one").on("deselect", function() {
alert("Radio button one was just deselected");
});
Then run something like the following function from your document ready handler (or put the code directly in your document ready handler):
function setupDeselectEvent() {
var selected = {};
$('input[type="radio"]').on('click', function() {
if (this.name in selected && this != selected[this.name])
$(selected[this.name]).trigger("deselect");
selected[this.name] = this;
}).filter(':checked').each(function() {
selected[this.name] = this;
});
}
Working demo: http://jsfiddle.net/s7f9s/2
What this does is puts a click handler on all the radios on the page (this doesn't stop you adding your own click event handlers to the same radios) that will check if there was a previously selected radio in the same group (i.e., with the same name) and if so trigger a "deselect" event on that radio. Then it saves the just-clicked one as the current one. The "deselect" event is not triggered if you click the already checked radio or if there was no previously checked one. The .filter().each() bit at the end is to make note of which radios are already selected. (If you need to cater for more than one form on the same page having independent radio groups of the same name then update the function above accordingly.)
I found that the simplest way to do this without putting in a new framework to create a deselected event, is to make changing any radio button trigger an update event on all of the radio buttons in its group and then define the behavior you want in the update event.
The downside is that the code in the deselection branch will run even if the radio button was not previously selected. If all you're doing is simple showing, hiding, or disabling UI elements, that shouldn't matter much.
To use your example:
buttons = $('input[name="a"]');
buttons.change(function() {
buttons.trigger('update:groupA');
}).bind('update:groupA', function(){
if(this.checked) {
//Do your checked things
} else {
//Do your unchecked things. Gets called whenever any other button is selected, so don't toggle or do heavy computation in here.
}
});​
I think you need to add the change function on the input level, rather than on each radio button.
Try this:
$("input[name='a']").change(function() {
$("input[name='a']").each(function(){
if(this.checked) {
// do something when selected
} else {
// do something when deselected
}
});
});​
I think this could be happening because the focus event triggers before the change event so the next radio you click will be focused before the previous checked radio triggers a change event. Don't quote me on this though...
You could do it like this:
var isChecked = function(id) { alert(id + ': ' + $('#' + id).is(':checked')) }
$('input[name="a"]').change(function(){ isChecked('one') })
Demo: http://jsfiddle.net/elclanrs/cD5ww/
You can trigger the 'change' event yourself. It's a bit tricky to avoid radio buttons infinitely triggering 'change' event on each other, but it can be done like this:
$('input[type="radio"]').each(function() {
var name = $(this).attr('name');
var that = this;
$('input[name="'+name+'"][type="radio"]').not(that)
.on('change', function(e, alreadyTriggered) {
if(!alreadyTriggered || alreadyTriggered.indexOf(this) == -1) {
if(!alreadyTriggered) {
alreadyTriggered = [that];
}
alreadyTriggered.push(this);
$(that).trigger('change', [alreadyTriggered]);
}
});
});
Here's the demo of the above code at work.
I found a workaround for my specific case that might help. This works when the "deselect" event can be applied to all radio buttons that aren't selected.
I wanted to:
add a class to the element when the radiobutton was selected, and
remove that class when the button was "deselected".
I happened to find this question, because I had the same problem:
$('input:radio').on('change', function() {
if( $(this).is(':checked') ) {
$(this).addClass('my-class-for-selected-buttons')
} else { // THIS WILL NEVER HAPPEN
$(this).removeClass('my-class-for-selected-buttons')
}
});​
But, in my case, the solution was pretty much easier, because I can try to remove the class from all the radio-buttons pretty simply with jQuery, and then add the class to the selected one:
$('input:radio').on('change', function() {
$('input:radio').removeClass('my-class-for-selected-buttons') // Here!
if( $(this).is(':checked') ) {
$(this).addClass('my-class-for-selected-buttons')
}
});​
With this simple tweak, I didn't need to find a way to trigger the "deselect" event.
So, if in your case you can apply the event to all the radio buttons that aren't selected, and not only to the one that's just been "deselected", you can use this measure!
Note: I'm using the most recent version of jquery: version 3.4.1. But this should work for older versions as well.
The major challenge here is that the change event is only triggered for the radio button that was checked. The code below confirms this.
$("input[name^='account']").change(function() {
console.log($(this).prop('id') + " was checked");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<form action='#'>
<input id='john' type='radio' name='account[]' value=''><label for='john'>John</label><br>
<input id='jane' type='radio' name='account[]' value=''><label for='jane'>Jane</label><br>
<input id='jeff' type='radio' name='account[]' value=''><label for='jeff'>Jeff</label><br>
<input id='jude' type='radio' name='account[]' value=''><label for='jude'>Jude</label><br>
<input type='text' name='amount' value=''><br>
<input type='submit' value='submit'>
</form>
My Solution: Handle everything inside the change event handler in 3 simple steps:
handle the changes for the currently checked radio button.
attach custom event and handler to all other radio buttons in the same group.
immediately trigger this custom event.
No need to play around with click events here. simple!
var radioBtns = $("input[name^='account']");
radioBtns.change(function() {
// 1. handle changes for the currently checked radio button.
console.log($(this).prop('id') + " was checked");
// 2. attach custom event and handler to all other radio buttons in the same group.
radioBtns.not(':checked').off('deselect').on('deselect', function() {
$(this).each(function(i, e) {
console.log($(e).prop('id') + " was not checked");
});
}).trigger('deselect'); // 3. immediately trigger this custom event.
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<form action='#'>
<input id='john' type='radio' name='account[]' value=''><label for='john'>John</label><br>

<input id='jeff' type='radio' name='account[]' value=''><label for='jeff'>Jeff</label><br>
<input id='jude' type='radio' name='account[]' value=''><label for='jude'>Jude</label><br>
<input type='text' name='amount' value=''><br>
<input type='submit' value='submit'>
</form>
I played a bit with the ids.
That is probably an inefficient solution to be fair.
<input type="radio" id="radio-1" name="a" value="initial 1"/>
<input type="radio" id="radio-2" name="a" value="initial 2"/>
let id;
$('input[id*="radio-"]').on('click', (function() {
if (this.id != id && this.checked) {
id = this.id;
this.checked = true;
console.log('selected');
} else if (this.id == id && this.checked) {
id = undefined;
this.checked = false;
console.log('deselected');
}
}));

Issue finding specific div with same class - JQuery

I have a file selector that populates a div with a thumbnail based on the file. Now I have multiple buttons and divs that contain the same class names. What I am using for each time the primary button is selected is, var thisButton = $(event.target); which translates to:
var appendThis = thisButton.closest('.insurance').find(".attachmentCont");
appendThis.append('<div class="singleImg"><img src="'+attachment.url+'" width="100px"/><input type="hidden" class="fileURL" value="'+attachment.id+'"/><span class="removeImg remove"> X </span></div>');
$(".removeImg").bind('click', function(){
$(this).parent().remove();
});
The appenThis equals the button which is within a div containing another div attachmentCont Both the button and div are within a parent div which is div.insurance There are multiple div.insurance containers. My issue is when using thisButton.closest('.insurance').find(".attachmentCont"); it always focuses on the .attachmentCont div that was first selected. So if I selected section 1, the image populates. If I select section 2, section 1 still gets that image when the div.attachmentCont within section 2 should of gotten the append() too.
Suggestions or Thoughts?
HTML EXAMPLE:
<div class="notes-section insurance">
<span><b>General </b></span><textarea style="width:97%;" rows="5" cols="50" class="insurance-description fields contractor_insurance_description" placeholder="...."></textarea>
<input type="date" class="expiration-date" placeholder="Expiration Date">
<br>
<span>Your</span>
<div class="attachmentCont">
</div>
<br>
<input type="button" class="upload_image_button" value="Attach Documents" style="width:150px;">
</div>
Here was the issue:
My blindness did not see that the function that contains the selected button was not in any way associated with the function that appended the data. Because of this all I had to do was move my var thisButton outside into the parent class.
Thank you everyone for you're time.
Solutions:
var thisButton
$('.upload_image_button').on('click', function( event ){
thisButton = $(event.target);
event.preventDefault();
});
....
function...({
var appendThis = thisButton.closest('.insurance').find(".attachmentCont");
appendThis.append('<div class="singleImg"><img src="'+attachment.url+'" width="100px"/><input type="hidden" class="fileURL" value="'+attachment.id+'"/><span class="removeImg remove"> X </span></div>');
$(".removeImg").bind('click', function(){
$(this).parent().remove();
});
});

problem with jquery for add cart button

hi i have a problem with displaying amount.i have the page called make payment in this page i made three radio buttons, if i click the button that amount must add with addcart like a product.
<form method="post" form name="make_payment_frm" action="module/make-payment-module.php" onsubmit="return show_make_payment_validation();" >
<form id='theForm'>
<input type="hidden" name="totalamount" id="totalamount" value="1" />
input type="radio" name="rmr" id="payment1" value="3" onclick="updatepayment(this.value)" />
input type="radio" name="rmr" id="payment2" value="5.5" onclick="updatepayment(this.value)"/>
input type="radio" name="rmr" id="payment4" value="10" onclick="updatepayment(this.value)"/>
div id="finalamount">
/div>
i think that problem is my js script. if i click that button there is no response. how do i solve that problem

$(document).ready(function() {
$(".cart :radio[name='rmr']").add(".cart :radio[name='rmr']").each(function() {
$(this).click(function() {
$(".cart :radio[name='rmr']").add(".cart :radio[name='rmr']").each(function() {
$(this).attr("checked", false);
});
$(this).attr("checked", true);
});
});
})
function updatePayment(val) {
$("<p/>").html("updatePayment(" + val + ")").appendTo(document.body);
}
thanks.have a nice day
I have no idea why you seem to be implementing the selecting and un-selecting of radio buttons in jQuery, surely HTML will handle that correctly for you.
However if you are using jQuery, do away with those onclick attributes since that is the benefit of jQuery and achieve the same result as follows:
$(function() {
$('.cart :radio[name="rmr"]').change(function() {
if ($(this).is(':checked'))
updatePayment(this.value);
});
});
This will attach a change event to every radio button input with the attribute name="rmr". Thus when the client clicks a new radio button, the value of two radio buttons will change, and the one that is then selected will call the updatePayment function with its value.
