Show/Hide divs based on radio button selection

I've gotten as far as showing a certain div based on the selection of "150" and "3m" but I can't get the div to hide if both of those aren't selected?

Code below:



$(document).ready(function() {
$('input[value="100"], input[value="3m"]').change(function() {
if ($('input[value="100"]').is(':checked') && $('input[value="3m"]').is(':checked')) {
$('div').show();
} else {
$('div').hide();
}
});
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>100</label>
<input class="amount" type="radio" name="amount" value="100" />
<label>150</label>
<input class="amount" type="radio" name="amount" value="150" />

<br>
<br>

<label>3</label>
<input class="month" type="radio" name="month" value="3m" />
<label>6</label>
<input class="month" type="radio" name="month" value="6m" />

<div style="display: none;">
<div class="interest">
£40
</div>
<div class="total-payable">
£140
</div>
<div class="monthly-payment">
£46.67
</div>
<div class="weekly-payment">
£10.77
</div>
</div>




Answer

Currently you're only updating the visibility of the div elements when the 100 or 3m radio button is changed - you want to update the visibility of the div elements on any radio button change by changing your selector:

$('input[value="100"], input[value="3m"]')

to

$('input')

$(document).ready(function() {
  $('input').change(function() {
    if ($('input[value="100"]').is(':checked') && $('input[value="3m"]').is(':checked')) {
      $('div').show();
    }
    else {
      $('div').hide();
    }
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>100</label>
<input class="amount" type="radio" name="amount" value="100" />
<label>150</label>
<input class="amount" type="radio" name="amount" value="150" />

<br><br>

<label>3</label>
<input class="month" type="radio" name="month" value="3m" />
<label>6</label>
<input class="month" type="radio" name="month" value="6m" />

<div style="display: none;">
<div class="interest">
£40
</div>
<div class="total-payable">
£140
</div>
<div class="monthly-payment">
£46.67
</div>
<div class="weekly-payment">
£10.77
</div>
</div>
