$(document).ready(function() {
    $('input[name="data[User][email_status]"]').change (function(){
        //console.log($(this).val());
        if ($(this).val() == 'no')  {
            $('input[name="data[User][no_alerts]"]').attr({

• Try to disable the checkbox – Steve Commented Nov 8, 2016 at 5:58
• Example : $('input[class="busiProp"]:not(:checked)').attr('disabled',true); – Bugfixer Commented Nov 8, 2016 at 6:50
• 2 Note: making an input element disabled will not submit it with the form. Thus, a checked checkbox that is also disabled will behave as if it were unchecked. Which is fine for the purposes of this question (given the description), but is not fine for the general case. – Denilson Sá Maia Commented Sep 21, 2017 at 12:50

Use the disabled property to make the input readonly

  $('input[value="no"]:checked').next().prop("disabled", true);

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="data[User][email_status]" id="" value="yes">Yes&nbsp;&nbsp;
<input type="radio" name="data[User][email_status]" id="" value="no" checked="checked">No
<input type="checkbox" name="data[User][no_alerts]" id="" value="yes">

 $('input[value="no"]:checked').parent().find('input[type="checkbox"]').prop("disabled", true);

$('input[name="data[User][no_alerts]"]').attr({
                'disabled' : true,
            });

You may like this code snippet:

$(function() {
  var chk = $('input[name="data[User][no_alerts]"]');//got check-box
  $('input[name="data[User][email_status]"]').on('change', function(e) {
    chk.prop('disabled', false); //enable first
    if ('no' == this.value) {
      chk.prop({
        'disabled': true,
        'checked': false
      });
    }
  });
  $('input[name="data[User][email_status]"]:checked').trigger('change');//fire code on page load
});

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="data[User][email_status]" id="" value="yes">Yes&nbsp;&nbsp;
<input type="radio" name="data[User][email_status]" id="" value="no" checked="checked">No
<input type="checkbox" name="data[User][no_alerts]" id="" value="yes">

this can also be used

 $('input[name="data[User][email_status]"]').change (function(){
            //console.log($(this).val());
            if ($(this).val() == 'no')  {
                $('input[name="data[User][no_alerts]"]').attr({
                    'checked' : false,
                    'disabled':"disabled",
                });
            }
        });
