Uncheck a checkbox when another is checked

Question

function uncheck() {
  var notTest = document.getElementById("choice_31_3_2");
  var Test = document.getElementById("choice_31_3_1");

  if (notTest.checked) {
    Test.checked = false;
  }
  if (Test.checked) {
    notTest.checked = false;
  }
}

jQuery("#choice_31_3_1").click(uncheck);
jQuery("#choice_31_3_2").click(uncheck);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>    

<input name="input_3.1" value="Test" id="choice_31_3_1" type="checkbox">
<label for="choice_31_3_1" id="label_31_3_1">Test</label>
<input name="input_3.2" value="notTest" id="choice_31_3_2" type="checkbox">
<label for="choice_31_3_2" id="label_31_3_2">notTest</label>

I wrote a function to uncheck a checkbox if another one is checked, I am using jQuery to call uncheck() on those specific input.

I am getting the result I want. When I check test then check notTest, Test is being unchecked. BUT when I am pressing Test again, the test checkbox is refusing to check unless I manually uncheck notTest.

I included the code snippet , please can figure out what is wrong ?

The code is running normally on Wordpress but unfortunately not here.

Here you go with a solution

$('input[type="checkbox"]').change(function(){
  console.log($(this).is(':checked'));
  if($(this).is(':checked')){
    $(this).siblings('input[type="checkbox"]').attr('checked', false);
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input name="input_3.1" value="Test" id="choice_31_3_1" type="checkbox">
<label for="choice_31_3_1" id="label_31_3_1">Test</label>
<input name="input_3.2" value="notTest" id="choice_31_3_2" type="checkbox">
<label for="choice_31_3_2" id="label_31_3_2">notTest</label>

Hope this will help you.

You can code like this,

 HTML:- 
 <input type="checkbox" class="example" />
 <input type="checkbox" class="example" />
 <input type="checkbox" class="example" />
 <input type="checkbox" class="example" />
 JQUERY:- 
 $('input.example').on('change', function() {
     $('input.example').not(this).prop('checked', false);  
 });
