如何将单选框下根据value值将这个功能进行隐藏(部分提示代码如下)

$$("pay-style").find('input[type="radio"][name="payType"][value="3"]').find('.page-content').addClass('hide');

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>
<body>
    <div class="pay-style">
        <input type="radio" name="payType" value="3">
    </div>
</body>
<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
<script>
   var payType3 = $('input[name="payType"]');
   console.log(payType3)
   if(payType3.val()==3){
       payType3.hide();
   }
   
</script>
</html>

最好还是给他们加个id这样好获取。jq里hide()就能直接隐藏
