Answer 1

Yes, it worked for me like a way:

$("#radio_1").attr('checked', 'checked');

Answer 2

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.

Answer 3

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);

Answer 4

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);
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<fieldset class="section">
  <legend>Radio buttons</legend>
  <label>
    <input type="radio" id="radio-1" checked>
    Option one is this and that&mdash;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>

Answer 5

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>

  $("#Id").prop("checked", true).checkboxradio('refresh');
});
