The problem statement is simple. I need to see if user has selected a radio button from a radio group. Every radio button in the group share same id.
The problem is that I don't have control on how the form is generated. Here is the sample code of how a radio button control code looks like:
<input type="radio" name='s_2_1_6_0' value='Mail copy to my bill to address' id = "InvCopyRadio" onchange = 'SWESubmitForm(document.SWEForm2_0,s_4,"","1-DPWJJF")' style="height:20;width:25" tabindex=1997 >
In addition to this when a radio button is selected it doesn't add a "checked" attribute to the control just text checked (I guess just the property checked without a value). Below is how a selected radio control looks like
<input type="radio" checked name='s_2_1_6_0' value='Mail copy to my bill to address' id = "InvCopyRadio" onchange = 'SWESubmitForm(document.SWEForm2_0,s_4,"","1-DPWJJF")' style="height:20;width:25" tabindex=1997 >
Can anybody help me with jQuery code that can help me to get the value of checked radio button?
Just use.
$('input[name="name_of_your_radiobutton"]:checked').val();
It is that easy.
First, you cannot have multiple elements with the same id. I know you said you can't control how the form is created, but...try to somehow remove all the ids from the radios, or make them unique.
To get the value of the selected radio button, select it by name with the :checked
filter.
var selectedVal = "";
var selected = $("input[type='radio'][name='s_2_1_6_0']:checked");
if (selected.length > 0) {
selectedVal = selected.val();
}
EDIT
So you have no control over the names. In that case I'd say put these radio buttons all inside a div, named, say, radioDiv
, then slightly modify your selector:
var selectedVal = "";
var selected = $("#radioDiv input[type='radio']:checked");
if (selected.length > 0) {
selectedVal = selected.val();
}
Simplest way to get the selected radio button's value is as follows:
$("input[name='optradio']:checked").val();
No space should be used in between selector.
$("#radioID") // select the radio by its id
.change(function(){ // bind a function to the change event
if( $(this).is(":checked") ){ // check if the radio is checked
var val = $(this).val(); // retrieve the value
}
});
Make sure to wrap this in the DOM ready function ($(function(){...});
or $(document).ready(function(){...});
).
radioID
to its ID?
In your code, jQuery just looks for the first instance of an input with name q12_3, which in this case has a value of 1. You want an input with name q12_3 that is :checked.
$(function(){
$("#submit").click(function() {
alert($("input[name=q12_3]:checked").val());
});
});
Note that the above code is not the same as using .is(":checked"). jQuery's is() function returns a boolean (true or false) and not an element.
<input type="radio" class="radioBtnClass" name="numbers" value="1" />1<br/>
<input type="radio" class="radioBtnClass" name="numbers" value="2" />2<br/>
<input type="radio" class="radioBtnClass" name="numbers" value="3" />3<br/>
This will return, checked radio button value.
if($("input[type='radio'].radioBtnClass").is(':checked')) {
var card_type = $("input[type='radio'].radioBtnClass:checked").val();
alert(card_type);
}
More details in my blog: https://webexplorar.com/jquery-get-selected-radio-button-value/
$("input[name='gender']:checked").val()
for nested attributes
$("input[name='lead[gender]']:checked").val()
Don't forget single braces for name
Get all radios:
var radios = $("input[type='radio']");
Filter to get the one that's checked
radios.filter(":checked");
OR
Another way you can find radio button value
var RadeoButtonStatusCheck = $('form input[type=radio]:checked').val();
$('[name=your_inputs_names]:checked').val()
cause they always have same unique name
.filter()
.filter()
. I wish this answer can be at the top.
To get the value of the selected Radio Button, Use RadioButtonName and the Form Id containing the RadioButton.
$('input[name=radioName]:checked', '#myForm').val()
OR by only
$('form input[type=radio]:checked').val();
This code works.
var radioValue = $("input[name='gender']:checked").val();
Check the example it works fine
<div class="dtl_radio">
Metal purity :
<label>
<input type="radio" name="purityradio" class="gold_color" value="92" checked="">
92 %
</label>
<label>
<input type="radio" name="purityradio" class="gold_color" value="75">
75 %
</label>
<label>
<input type="radio" name="purityradio" class="gold_color" value="58.5">
58.5 %
</label>
<label>
<input type="radio" name="purityradio" class="gold_color" value="95">
95 %
</label>
<label>
<input type="radio" name="purityradio" class="gold_color" value="59">
59 %
</label>
<label>
<input type="radio" name="purityradio" class="gold_color" value="76">
76 %
</label>
<label>
<input type="radio" name="purityradio" class="gold_color" value="93">
93 %
</label>
</div>
var check_value = $('.gold_color:checked').val();
Use Below Code
$('input[name=your_radio_button_name]:checked').val();
Please note, value attribute should be defined so could get "Male" or "Female" in your result.
<div id='div_container'>
<input type="radio" name="Gender" value="Male" /> Male <br />
<input type="radio" name="Gender" value="Female" /> Female
</div>
See below for working example with a collection of radio groups each associated with different sections. Your naming scheme is important, but ideally you should try and use a consistent naming scheme for inputs anyway (especially when they're in sections like here).
$('#submit').click(function(){ var section = $('input:radio[name="sec_num"]:checked').val(); var question = $('input:radio[name="qst_num"]:checked').val(); var selectedVal = checkVal(section, question); $('#show_val_div').text(selectedVal); $('#show_val_div').show(); }); function checkVal(section, question) { var value = $('input:radio[name="sec'+section+'_r'+question+'"]:checked').val() || "Selection Not Made"; return value; } * { margin: 0; } div { margin-bottom: 20px; padding: 10px; } h5, label { display: inline-block; } .small { font-size: 12px; } .hide { display: none; } #formDiv { padding: 10px; border: 1px solid black; } .center { display:block; margin: 0 auto; text-align:center; }
if (!$("#InvCopyRadio").prop("checked") && $("#InvCopyRadio").prop("checked"))
// do something
undefined
when you know for certain the value must be checked
? There's no need in jQuery.
"undefined"
is unnecessary.
Try this with example
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1 /jquery.min.js"></script>
<form id="myForm">
<input type="radio" name="radio" value="first"/> 1 <br/>
<input type="radio" name="radio" value="second"/> 2 <br/>
</form>
<script>
$(document).ready(function () {
$('#myForm').on('click', function () {
var value = $("[name=radio]:checked").val();
alert(value);
})
});
</script>
By Name only
$(function () {
$('input[name="EventType"]:radio').change(function () {
alert($("input[name='EventType']:checked").val());
});
});
You can get the value of selected radio button by Id using this in javascript/jQuery.
$("#InvCopyRadio:checked").val();
I hope this will help.
I know that I am joining this late. But it is worth mentioning that it takes
<label class="custom-control-label" for="myRadioBtnName">Personal Radio Button</label>
And then I checked this in my js. It could be like
$(document).ready(function () {
$("#MyRadioBtnOuterDiv").click(function(){
var radioValue = $("input[name=myRadioButtonNameAttr]:checked").val();
if(radioValue === "myRadioBtnName"){
$('#showMyRadioArea').show();
}else if(radioValue === "yourRadioBtnName"){
$('#showYourRadioArea').show();
}
});
});

Here is a shorter version of getting value of selected radio button
var value = $(":radio:checked").val()
The best way to explain this simple topic is by giving simple example and reference link:-
In the following example we have two radio buttons. If the user selects any radio button, we will display the selected radio button value in a alert box.
Html:
<form id="Demo">
<input type="radio" name="Gender" value="Male" /> Male <br />
<input type="radio" name="Gender" value="Female" /> Female<br />
<input type="radio" name="Gender" value="others" /> others <br />
</form>
jquery:-
$(document).ready(function(){
$('#Demo input').on('change', function() {
alert($('input[name="Gender"]:checked', '#Demo').val());
});
});
<div id="subscriptions">
Company Suscription: <input type="radio" name="subsrad" value="1">
Customer Subscription:<input type="radio" name="subsrad" value="2">
Manully Set:<input type="radio" name="subsrad" value="MANUAL">
NO Subscription:<input type="radio" name="subsrad" value="0">
</div>
and handle jquery for alert as for th e value set / Changed through div id:
$("#subscriptions input") // select the radio by its id
.on('change', function(){ // bind a function to the change event
alert($('input[name="subsrad"]:checked', '#subscriptions').val());
});
it is so easy....:-}
I am not a javascript person, but I found here for searching this problem. For who google it and find here, I am hoping that this helps some. So, as in question if we have a list of radio buttons:
<div class="list">
<input type="radio" name="b1" value="1">
<input type="radio" name="b2" value="2" checked="checked">
<input type="radio" name="b3" value="3">
</div>
I can find which one selected with this selector:
$('.list input[type="radio"]:checked:first').val();
Even if there is no element selected, I still don't get undefined error. So, you don't have to write extra if statement before taking element's value.
Here is very basic jsfiddle example.
Another Easy way to understand... It's Working:
HTML Code:
<input type="radio" name="active_status" class="active_status" value="Hold">Hold
<input type="radio" name="active_status" class="active_status" value="Cancel">Cancel
<input type="radio" name="active_status" class="active_status" value="Suspend">Suspend
Jquery Code:
$(document).on("click", ".active_status", function () {
var a = $('input[name=active_status]:checked').val();
(OR)
var a = $('.active_status:checked').val();
alert(a);
});
multi group radio button covert value to array
var arr = [];
function r(n) {
var section = $('input:radio[name="' + n + '"]:checked').val();
arr[n] = section;
console.log(arr)
}

Even input
is not necessary as suggested by other answers. The following code can also be used:
var variable_name = $("[name='radio_name']:checked").val();
input
and with unnecessary quote marks.
Here are 2 radio buttons namely rd1 and Radio1
<input type="radio" name="rd" id="rd1" />
<input type="radio" name="rd" id="Radio1" />
The simplest wayt to check which radio button is checked ,by checking individual is(":checked") property
if ($("#rd1").is(":checked")) {
alert("rd1 checked");
}
else {
alert("rd1 not checked");
}
HTML Markup :
<div class="form-group">
<input id="rdMale" type="radio" class="clsGender" value="Male" name="rdGender" /> Male
<input id="rdFemale" type="radio" class="clsGender" value="Female" name="rdGender" /> Female
</div>
Get selected value by radio button Id:
$("input[name='rdGender']").click(function () {
alert($("#rdMale").val());
});
Get value by radiobutton Classname
$(".clsGender").click(function () {
alert($(this).val());
//or
alert($(".clsGender:checked").val());
});
Get value by name
$("input[name='rdGender']").click(function () {
var rdVaule = $("input[name='rdGender']:checked").val();
alert(rdVaule);
});
For multiple radio buttons, you have to put same name attribute on your radio button tag. For example;
<input type="radio" name"gender" class="select_gender" value="male">
<input type="radio" name"gender" class="select_gender" value="female">
Once you have radio options, now you can do jQuery code like below to get he value of selected/checked radio option.
$(document).on("change", ".select_gender", function () {
console.log($(this).val()); // Here you will get the current selected/checked radio option value
});
Note: $(document) is used because if the radio button are created after DOM 100% loaded, then you need it, because if you don't use $(document) then jQuery will not know the scope of newly created radion buttons. It's a good practice to do jQuery event calls like this.
<input type="radio" name='s_2_1_6_0' value='Mail copy to my bill to address' id = "InvCopyRadio" onchange = 'SWESubmitForm(document.SWEForm2_0,s_4,"","1-DPWJJF")' style="height:20;width:25" tabindex=1997 >
$(function() {
$("#submit").click(function() {
alert($('input[name=s_2_1_6_0]:checked').val());
});
});`
HTML Code
<input id="is_verified" class="check" name="is_verified" type="radio" value="1"/>
<input id="is_verified" class="check" name="is_verified" type="radio" checked="checked" value="0"/>
<input id="submit" name="submit" type="submit" value="Save" />
Javascript Code
$("input[type='radio'].check").click(function() {
if($(this).is(':checked')) {
if ($(this).val() == 1) {
$("#submit").val("Verified & Save");
}else{
$("#submit").val("Save");
}
}
});
Success story sharing
null
, which is logical but sometimes can confuse you when you're used to seeing""
as the default value via the.val()
call.
