JQuery单选按钮分层元素隐藏

Question

我正在尝试使用/调整现有脚本来显示/隐藏基于选择的分层系列单选按钮。请参阅下面的代码。问题是当选择第3级单选按钮时，第2级单选按钮消失。似乎罪魁祸首是$（“。opthide”）。not（targetBox）.hide（）;但我不确定如何限制隐藏到相关元素。

$(document).ready(function() {
  $('input[name="insv_sts5"]').click(function() {
    var inputValue = $(this).attr("value");
    var targetBox = $("." + inputValue);
    $(".opthide").not(targetBox).hide();
    $(targetBox).show();
  });
});

$(document).ready(function() {
  $('input[name="insv_sts6"]').click(function() {
    var inputValue = $(this).attr("value");
    var targetBox = $("." + inputValue);
    $(".opthide").not(targetBox).hide();
    $(targetBox).show();
  });
});

$(document).ready(function() {
  $('input[name="insv_sts9"]').click(function() {
    var inputValue = $(this).attr("value");
    var targetBox = $("." + inputValue);
    $(".opthide").not(targetBox).hide();
    $(targetBox).show();
  });
});

.opthide {
  display: none;
}

欢迎来到SO，

这是我的2美分。 我做了循环点击所有单选按钮，如果按钮被选中它会显示目标元素，如果它不是它清除检查下级按钮并隐藏元素，这需要防止元素显示即使用户改变主意并更改一些顶级复选框。

希望它有所帮助，如果您有任何问题或任何人有不同的方法让我知道。

最终看起来像这样。

＆＃13;

$(document).ready(function() {
  $('input[type="radio"]').click(function() {   
    $('input[type="radio"]').each(function () {
      //iterate through all radio buttons
      var $target = $(this).val()  //get target class from value     
      if ($(this).prop('checked')) {  //check if radio box is checked             
        $('.' + $target).show()  //show target tr
      } else {
        //hide target tr and uncheck all radio buttons in child element
        $('.' + $target).hide().find('input[type="radio"]').prop('checked', false);        
      }      
    })    
  });
});
