I have a series of dyanmic checkboxes which are creating at runtime but with differnt Ids like this (patter is same)
ModellingTagID_1201
ModellingTagID_1202
ModellingTagID_1203
ModellingTagID_1204
I want to know that above check box change or not? how can i make a dyanmic event with dynamic selector? so that i can get that particular checkbox value has changed? is this kind of thing possible?
$jqLib("#ModellingTagID_*").change(function(){
var lastState =$jqLib("#ModellingTagAlternativePlanning").prop("disabled");
$jqLib("#ModellingTagAlternativePlanning").prop("disabled",!lastState);
});
you can apply same class to all those checkboxes
<li><input type="checkbox" id="yourcbid1" name="x" value="1" class="yourcbclass" /> cb1</li>
<li><input type="checkbox" id="yourcbid2" name="x" value="1" class="yourcbclass" /> cb2</li>
and then you can make function for it's change event like this.
$(function(){
$('.yourcbclass').on('change', function() {
if($(this).is(':checked'))
{
//do your stuff here
}
});
});
see if this helps..
Very simple using this way:--
$("#envoyer").click(function(e) {
var myArray = [];
$(":checkbox:checked").each(function() {
myArray.push(this.value);
});
if(myArray == ''){
alert('Please check');
}else{
alert("Checked: " + myArray.join(","));
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<html>
<body>
one<input type="checkbox" name='checkbox0' value="one_name" checked>
two<input type="checkbox" name='checkbox1' value="one_name1">
three<input type="checkbox" name='checkbox2' value="one_name2">
<input type="button" id="envoyer" value="Envoyer Reponse" />
</body>
</html>
From what I understand, your issue is to distinguish the unique id of the checkbox, which is being, changed. To achieve this, you can simply add a common class to all the elements, alongwith unique random ids.
cb_1<input type="checkbox" class="someclass" id='ModellingTagID_1201' value="value_1" checked>
cb_2<input type="checkbox" class="someclass" id='ModellingTagID_1202' value="value_2">
cb_3<input type="checkbox" class="someclass" id='ModellingTagID_1203' value="value_3">
And then you can simply bind a change event listener to the common class, and fetch the value of the random id, which has been changed, from inside the event listener.
$(document).ready(function(){
$('.someclass').on('change', function() {
alert($(this).attr("id"));
});
});
I have read this post and this post and others but i didnt get it to work in my code.
here is the Fiddle for better see my code on live.
this is my js
//////first code to try////
if ($('input.chek').is(':checked')) {
$('.check-addon').css('background-color','green');
}
//////second code///////
var boxes = $('input[class="chek"]:checked');
$(boxes).each(function(){
$('.check-addon').css('background-color','green');
});
this is my html
<div class="inline-container"><div class="checkboxes" >
<span class="check-addon"><input id="id1" class="chek" type="checkbox" value="1" name="id1">title1</span>
<span class="check-addon"><input id="id2" type="checkbox" class="chek" value="1" name="id2">title2</span>
<span class="check-addon"><input id="id3" type="checkbox" class="chek" value="1" name="id3">title3</span>
</div></div>
i dont know what im doing wrong here . i couldnt get the background Green Of the checked box in my code.
any help would much apreciated.
EDIT
even the answers down works in fiddle But i guess i have more problem here.
if i write html code above Normal , the js code is fired and works But im using html code inside js function like that:
function houses(){
var x ='<div class="inline-container"><div class="checkboxes" >
<span class="check-addon"><input id="id1" class="chek" type="checkbox" value="1" name="id1">title1</span>
<span class="check-addon"><input id="id2" type="checkbox" class="chek" value="1" name="id2">title2</span>
<span class="check-addon"><input id="id3" type="checkbox" class="chek" value="1" name="id3">title3</span>
</div></div>';
return x ;
}
so this function when i call it it works but when i want apply the above code on it its not working and not firing at all.
this function is Out of the Dom handler. Fiddle here
Bind the input with a on change event
$('.chek').on('change', function () {
$(this).closest('.check-addon').css('background-color',this.checked?'green':'none');
});
DEMO
Update
You need to use event-delegation on dynamically added elements
$(document).on('change','.chek',function(){
$(this).closest('.check-addon').css('background-color',this.checked?'green':'none');
});
You need to use click/change event to detect the changes on checkboxes. Use:
$('input').change(function(){
if (this.checked)
$(this).parent().css('background-color','green');
else
$(this).parent().css('background-color','none');
});
Demo
You can use this:
$("input:checkbox").on("change", function(){
if($(this).prop("checked")){
$(this).parent(".check-addon").css('background-color','green');
}
else{
$(this).parent(".check-addon").css('background-color','white');
}
});
fiddle
You have to do like this :
1st Way:
$(".chek").change(function () { // will fire when checkbox checked or unchecked
if (this.checked) // check if it is checked
$(this).closest(".check-addon").css('background-color', 'green'); //find parent span and add css
else
$(this).closest(".check-addon").css('background-color','transparent');
})
FIDDLE:
http://jsfiddle.net/2u697b57
2nd Way:
More better approach is to create a css class and add/remove it on check/uncheck:
CSS:
.green
{
background-color:green;
}
JQUERY:
$(".chek").change(function () {
if (this.checked)
$(this).closest(".check-addon").addClass("green");
else
$(this).closest(".check-addon").removeClass("green");

I'm new to JavaScript. Here's my code:
<script>
function text_input_type(type)
{
if(type=='list'){
document.getElementById("note_input").innerHTML="<input type=\"text\" name=\"body\">";
}
else{
document.getElementById("note_input").innerHTML="<textarea id=\"note_input\" name=\"body\" cols=\"27\" rows=\"5\"></textarea>";
}
}
</script>
<textarea id="note_input" name="body" cols="27" rows="5"></textarea>
<input type="radio" name="type" value="text" onclick=text_input_type('list') />
<input type="radio" name="type" value="list" onclick=text_input_type('text') />
I want it so that depending on which radio button you press it changes from a textarea to a input text type. The problem is instead of changing the input from a textbox to a smaller text input it just prints the code inside the box.
Hope this helps you in solving your problem.
<script>
function text_input_type(type)
{
if(type=='list'){
document.getElementById("note_input").innerHTML="<input type=\"text\" id=\"note_input1\" name=\"body\">";
}
else{
document.getElementById("note_input").innerHTML="<textarea id=\"note_input1\" name=\"body\" cols=\"27\" rows=\"5\"></textarea>";
}
}
</script>
<div id="note_input"><textarea id="note_input1" name="body" cols="27" rows="5"></textarea></div>
<input type="radio" name="type" value="text" onclick=text_input_type('list') />
<input type="radio" name="type" value="list" onclick=text_input_type('text') />
Try this code, you will get what you want.
Your code is correct, except for a small change.
<html>
<body>
<input type="radio" name="type" value="text" onclick="text_input_type('list');" />
<input type="radio" name="type" value="list" onclick="text_input_type('text');" />
<div id="note_input">
</body>
</html>
Should work fine
Bind the click handlers with Javascript too—inline Javascript isn't really necessary:
var elems = [].slice.call( document.getElementsByTagName("input") );
elems.forEach( function( elem ){
elem.onclick = function(){
var type = this.value;
if( type === 'list' ){
alert("type is list");
} else {
alert("type is not list");
}
};
});
Example.
I'm aware that this can be a little complicated. What we're simply doing is attaching a click function to each of the input tags on the page. We set the value of the clicked input tot he type variable and check if that variable is equal to the string list. If it is, then we fire the code in the if. If not, we fire the code in the else.
Essentially what this does is make it easier for you. You just put this code in your JS file and you don't have to worry about assigning the onclick on the elements themselves (and it looks you were doing it for two of them).
However, your code will work if you surround the onclick with quotes, like so:
onclick="text_input_type('list');"
I try to check a radio button with jQuery. Here's my code:
<form>
<div id='type'>
<input type='radio' id='radio_1' name='type' value='1' />
<input type='radio' id='radio_2' name='type' value='2' />
<input type='radio' id='radio_3' name='type' value='3' />
</div>
</form>
And the JavaScript:
jQuery("#radio_1").attr('checked', true);
Doesn't work:
jQuery("input[value='1']").attr('checked', true);
Doesn't work:
jQuery('input:radio[name="type"]').filter('[value="1"]').attr('checked', true);
Doesn't work:
Do you have another idea? What am I missing?
For versions of jQuery equal or above (>=) 1.6, use:
$("#radio_1").prop("checked", true);
For versions prior to (<) 1.6, use:
$("#radio_1").attr('checked', 'checked');
Tip: You may also want to call click() or change() on the radio button afterwards. See comments for more info.
Try this.
In this example, I'm targeting it with its input name and value
$("input[name=background][value='some value']").prop("checked",true);
Good to know: in case of multi-word value, it will work because of apostrophes, too.
Short and easy to read option:
$("#radio_1").is(":checked")
It returns true or false, so you can use it in "if" statement.
One more function prop() that is added in jQuery 1.6, that serves the same purpose.
$("#radio_1").prop("checked", true);
Try this.
To check Radio button using Value use this.
$('input[name=type][value=2]').attr('checked', true);
Or
$('input[name=type][value=2]').attr('checked', 'checked');
Or
$('input[name=type][value=2]').prop('checked', 'checked');
To check Radio button using ID use this.
$('#radio_1').attr('checked','checked');
Or
$('#radio_1').prop('checked','checked');
Use prop() mehtod

The $.prop way is better:
$(document).ready(function () {
$("#radio_1").prop('checked', true);
});
and you can test it like the following:
$(document).ready(function () {
$("#radio_1, #radio_2", "#radio_3").change(function () {
if ($("#radio_1").is(":checked")) {
$('#div1').show();
}
else if ($("#radio_2").is(":checked")) {
$('#div2').show();
}
else
$('#div3').show();
});
});
Try This:
$("input[name=type]").val(['1']);

Surprisingly, the most popular and accepted answer ignores triggering appropriate event despite of the comments. Make sure you invoke .change(), otherwise all the "on change" bindings will ignore this event.
$("#radio_1").prop("checked", true).change();
You have to do
jQuery("#radio_1").attr('checked', 'checked');
That's the HTML attribute
Try this
$(document).ready(function(){
$("input[name='type']:radio").change(function(){
if($(this).val() == '1')
{
// do something
}
else if($(this).val() == '2')
{
// do something
}
else if($(this).val() == '3')
{
// do something
}
});
});
If property name does not work don't forget that id still exists. This answer is for people who wants to target the id here how you do.
$('input[id=element_id][value=element_value]').prop("checked",true);
Because property name does not work for me. Make sure you don't surround id and name with double/single quotations.
Cheers!
We should want to tell it is a radio button.So please try with following code.
$("input[type='radio'][name='userRadionButtonName']").prop('checked', true);
Yes, it worked for me like a way:
$("#radio_1").attr('checked', 'checked');
This answer is thanks to Paul LeBeau in a comment. I thought I'd write it up as a proper answer since there surprisingly wasn't one.
The only thing that worked for me (jQuery 1.12.4, Chrome 86) was:
$(".js-my-radio-button").trigger("click");
This does everything I want – changes which radio button looks selected (both visually and programmatically) and triggers events such as change on the radio button.
Just setting the "checked" attribute as other answers suggest would not change which radio button was selected for me.
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>
$("input[name=inputname]:radio").click(function() {
if($(this).attr("value")=="yes") {
$(".inputclassname").show();
}
if($(this).attr("value")=="no") {
$(".inputclassname").hide();
}
});
Get value:
$("[name='type'][checked]").attr("value");
Set value:
$(this).attr({"checked":true}).prop({"checked":true});
Radio Button click add attr checked:
$("[name='type']").click(function(){
$("[name='type']").removeAttr("checked");
$(this).attr({"checked":true}).prop({"checked":true});
});
Just in case anyone is trying to achieve this while using jQuery UI, you will also need to refresh the UI checkbox object to reflect the updated value:
$("#option2").prop("checked", true); // Check id option2
$("input[name='radio_options']").button("refresh"); // Refresh button set
I use this code:
I'm sorry for English.
var $j = jQuery.noConflict();
$j(function() {
// add handler
$j('#radio-1, #radio-2').click(function(){
// find all checked and cancel checked
$j('input:radio:checked').prop('checked', false);
// this radio add cheked
$j(this).prop('checked', true);
});
});

<fieldset class="section">
<legend>Radio buttons</legend>
<label>
<input type="radio" id="radio-1" checked>
Option one is this and that—be sure to include why it's great
</label>
<br>
<label>
<input type="radio" id="radio-2">
Option two can be something else
</label>
</fieldset>
Try this
var isChecked = $("#radio_1")[0].checked;
I've just have a similar problem, a simple solution is to just use:
.click()
Any other solution will work if you refresh radio after calling function.
function rbcitiSelction(e) {
debugger
$('#trpersonalemail').hide();
$('#trcitiemail').show();
}
function rbpersSelction(e) {
var personalEmail = $(e).val();
$('#trpersonalemail').show();
$('#trcitiemail').hide();
}
$(function() {
$("#citiEmail").prop("checked", true)
});
$("#radio_1").attr('checked', true);
//or
$("#radio_1").attr('checked', 'checked');
I got some related example to be enhanced, how about if I want to add a new condition, lets say, if I want colour scheme to be hidden after I click on project Status value except Pavers and Paving Slabs.
Example is in here:
$(function () {
$('#CostAnalysis input[type=radio]').click(function () {
var value = $(this).val();
if (value == "Supply & Lay") {
$('#ul-suplay').empty();
$('#ul-suplay').append('<fieldset data-role="controlgroup"> \
http://jsfiddle.net/m7hg2p94/4/
attr accepts two strings.
The correct way is:
jQuery("#radio_1").attr('checked', 'true');
In addition, you can check if the element is checked or not:
if ($('.myCheckbox').attr('checked'))
{
//do others stuff
}
else
{
//do others stuff
}
You can checked for unchecked element:
$('.myCheckbox').attr('checked',true) //Standards way
You can also uncheck this way:
$('.myCheckbox').removeAttr('checked')
You can checked for radio button:
For versions of jQuery equal or above (>=) 1.6, use:
$("#radio_1").prop("checked", true);
For versions prior to (<) 1.6, use:
$("#radio_1").attr('checked', 'checked');
I used jquery-1.11.3.js
Basic Enable & disable
Tips 1: (Radio button type common Disable & Enable)
$("input[type=radio]").attr('disabled', false);
$("input[type=radio]").attr('disabled', true);
Tips 2: ( ID selector Using prop() or attr())
$("#paytmradio").prop("checked", true);
$("#sbiradio").prop("checked", false);
jQuery("#paytmradio").attr('checked', 'checked'); // or true this won't work
jQuery("#sbiradio").attr('checked', false);
Tips 3: ( Class selector Using prop() or arrt())
$(".paytm").prop("checked", true);
$(".sbi").prop("checked", false);
jQuery(".paytm").attr('checked', 'checked'); // or true
jQuery(".sbi").attr('checked', false);
OTHER TIPS
$("#paytmradio").is(":checked") // Checking is checked or not
$(':radio:not(:checked)').attr('disabled', true); // All not check radio button disabled
$('input[name=payment_type][value=1]').attr('checked', 'checked'); //input type via checked
$("input:checked", "#paytmradio").val() // get the checked value
index.html
<div class="col-md-6">
<label class="control-label" for="paymenttype">Payment Type <span style="color:red">*</span></label>
<div id="paymenttype" class="form-group" style="padding-top: inherit;">
<label class="radio-inline" class="form-control"><input type="radio" id="paytmradio" class="paytm" name="paymenttype" value="1" onclick="document.getElementById('paymentFrm').action='paytmTest.php';">PayTM</label>
<label class="radio-inline" class="form-control"><input type="radio" id="sbiradio" class="sbi" name="paymenttype" value="2" onclick="document.getElementById('paymentFrm').action='sbiTest.php';">SBI ePAY</label>
</div>
</div>
try this
$("input:checked", "#radioButton").val()
if checked returns True
if not checked returns False
jQuery v1.10.1
Some times above solutions do not work, then you can try below:
jQuery.uniform.update(jQuery("#yourElementID").attr('checked',true));
jQuery.uniform.update(jQuery("#yourElementID").attr('checked',false));
Another way you can try is:
jQuery("input:radio[name=yourElementName]:nth(0)").attr('checked',true);
How do I call onclick on a radiobutton list using javascript?
How are you generating the radio button list? If you're just using HTML:
<input type="radio" onclick="alert('hello');"/>
If you're generating these via something like ASP.NET, you can add that as an attribute to each element in the list. You can run this after you populate your list, or inline it if you build up your list one by one:
foreach(ListItem RadioButton in RadioButtons){
RadioButton.Attributes.Add("onclick", "alert('hello');");
}
More info: http://www.w3schools.com/jsref/event_onclick.asp
To trigger the onClick event on a radio button, invoke the click() method on its DOM element:
document.getElementById("radioButton").click()
using jQuery:
$("#radioButton").click()
AngularJs:
angular.element('#radioButton').trigger('click')
I agree with #annakata that this question needs some more clarification, but here is a very, very basic example of how to set up an onclick event handler for the radio buttons:
window.onload = function() {
var ex1 = document.getElementById('example1');
var ex2 = document.getElementById('example2');
var ex3 = document.getElementById('example3');
ex1.onclick = handler;
ex2.onclick = handler;
ex3.onclick = handler;
}
function handler() {
alert('clicked');
}
<input type="radio" name="example1" id="example1" value="Example 1" />
<label for="example1">Example 1</label>
<input type="radio" name="example2" id="example2" value="Example 2" />
<label for="example1">Example 2</label>
<input type="radio" name="example3" id="example3" value="Example 3" />
<label for="example1">Example 3</label>
The problem here is that the rendering of a RadioButtonList wraps the individual radio buttons (ListItems) in span tags and even when you assign a client-side event handler to the list item directly using Attributes it assigns the event to the span. Assigning the event to the RadioButtonList assigns it to the table it renders in.
The trick here is to add the ListItems on the aspx page and not from the code behind. You can then assign the JavaScript function to the onClick property. This blog post; attaching client-side event handler to radio button list by Juri Strumpflohner explains it all.
This only works if you know the ListItems in advance and does not help where the items in the RadioButtonList need to be dynamically added using the code behind.
I think all of the above might work. In case what you need is simple, I used:
function checkRadio(name) {
if (name == "one") {
console.log("Choice: ", name);
document.getElementById("one-variable-equations").checked = true;
document.getElementById("multiple-variable-equations").checked = false;
} else if (name == "multiple") {
console.log("Choice: ", name);
document.getElementById("multiple-variable-equations").checked = true;
document.getElementById("one-variable-equations").checked = false;
}
}
<div class="radio-buttons-choice" id="container-3-radio-buttons-choice">
<input type="radio" name="one" id="one-variable-equations" onclick="checkRadio(name)"><label>Only one</label><br>
<input type="radio" name="multiple" id="multiple-variable-equations" onclick="checkRadio(name)"><label>I have multiple</label>
</div>
Try the following solution
$(document).ready(function() {
$('.radio').click(function() {
document.getElementById('price').innerHTML = $(this).val();
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="variant">
<label><input type="radio" name="toggle" class="radio" value="19,99€"><span>A</span></label>
<label><input type="radio" name="toggle" class="radio" value="<<<"><span>B</span></label>
<label><input type="radio" name="toggle" class="radio" value="xxx"><span>C</span></label>
<p id="price"></p>
</div>
The other answers did not work for me, so I checked Telerik's official documentation it says you need to find the button and call the click() function:
function KeyPressed(sender, eventArgs) {
var button = $find("<%= RadButton1.ClientID %>");
button.click();
}
