Show/hide DIV based on selected radio button input

问题

I'm trying to toggle multiple DIVs that have the same data attribute value based on the value of the select radio button.

But I'm not sure what's wrong with my code below.

By default, the first radio button is always selected on load, how do I trigger it to show the 3 DIVs of the matching value?

Mark-up:

<nav id="gift-subs-options">
    <ul>
        <li class="selected">
            <label>
                <input type="radio" name="subscription-period" value="3mths" checked />
                <span class="period">3 months</span>                        
            </label>
        </li>
        <li>
            <label>
                <input type="radio" name="subscription-period" value="6mths" />
                <span class="period">6 months</span>
            </label>
        </li>
        <li>
            <label>
                <input type="radio" name="subscription-period" value="12mths" />
                <span class="period">12 months</span>
            </label>
        </li>
    </ul>
</nav>

<div class="prices" data-period="3mths">A 1</div>
<div class="prices" data-period="6mths">B 1</div>
<div class="prices" data-period="12mths">C 1</div>

<div class="prices" data-period="3mths">A 2</div>
<div class="prices" data-period="6mths">B 2</div>
<div class="prices" data-period="12mths">C 2</div>

<div class="prices" data-period="3mths">A 2</div>
<div class="prices" data-period="6mths">B 2</div>
<div class="prices" data-period="12mths">C 3</div>

JS:

$(document).ready(function() {
    $(".prices").hide();

    $("input[name$='subscription-period']").click(function() {
        var test = $(this).val();
        $(".prices[data-period]='" + test + "'").show();
    });
});

回答1:

What you have given is syntactically wrong. You need to give this way:

$(".prices[data-period='" + test + "']").show();

Also hide other divs before refreshing.

$(".prices").hide();

Full Code:

$(document).ready(function() {
    $(".prices").hide();

    $("input[name$='subscription-period']").click(function() {
        var test = $(this).val();
        $(".prices").hide();
        $(".prices[data-period='" + test + "']").show();
    });
});

$(document).ready(function() {

    $("input[name='subscription-period']").click(function() {

    });
});

Read attribute equals selector

DEMO

$(document).ready(function () {
    $(".prices").hide();

    $("input[name$='subscription-period']").change(function () {
        var test = this.value;
        $(".prices").hide();
        $(".prices[data-period='" + test + "']").show();
    });
});

Use following :

$(document).ready(function() {
   $(".prices").hide();

   var defaultval=$("input[name$='subscription-period']").val();
   $(".prices[data-period='" + defaultval + "'").show();
   $("input[name$='subscription-period']").change(function() {
      $(".prices").hide();
      var test = $(this).val();
      $(".prices[data-period='" + test + "'").show();
  });
});
