两个星级评级系统总是输出第二个父级ID的ID

Question

问题是我有两个星级评分系统。每个星级评分系统的父级fieldset都有不同的ID。如果用户点击第一个星级评分系统，我希望它输出该父容器的ID，如果他们点击第二个星级评分系统，我希望它输出该父容器的ID。

但是，两个星级评分系统都会输出第二个（最后一个）字段集容器的ID。

$(document).on('change', 'input[type="radio"]', function (e) {
        console.log($(this).parent().attr('id'));
});

fieldset,
label {
  margin: 0;
  padding: 0;
  margin-bottom: 20px;
}

.rating {
  border: none;
  float: left;
}

.rating>input {
  display: none;
}

.rating>label:before {
  margin: 5px;
  font-size: 1.25em;
  font-family: FontAwesome;
  display: inline-block;
  content: "\f005";
}

.rating>.half:before {
  content: "\f089";
  position: absolute;
}

.rating>label {
  color: #ddd;
  float: right;
}

.rating>input:checked~label,

/* show gold star when clicked */

.rating:not(:checked)>label:hover,

/* hover current star */

.rating:not(:checked)>label:hover~label {
  color: #FFD700;
}


/* hover previous stars in list */

.rating>input:checked+label:hover,

/* hover current star when changing rating */

.rating>input:checked~label:hover,
.rating>label:hover~input:checked~label,

/* lighten current selection */

.rating>input:checked~label:hover~label {
  color: #FFED85;
}

如果您查看我的问题Onclick event runs twice，您会看到答案是：

• 为每个输入提供一个唯一的ID（因为它们是两组星级评定系统）
• 更改HTML结构，以便每个输入都在标签内。

不幸的是，这些都没有真正帮助，因为第一个选项不方便更改每个星级评级集的ID，而第二个选项，它会破坏我的CSS，如Stars (radio button) won't change colour when selected

我该怎么办？

问题确实是重复ID ，因为您不想手动（可理解），可能因为有数百种或其他原因。以下方法是对已生成的标记进行后处理（如果您自己生成标记，请按照生成它们的相同技术，而不是AFTER）。

像这样，每个input都有自己唯一的ID和（非常重要！）相应的label也会有必要的for属性。

随意重构效率。

$(document).ready(function(){
$('fieldset').each(function(){
          var parentId = $(this).attr('id');
          $(this).children('input').each(function(){
            var newId = $(this).attr('id') + "-" + parentId;
            $(this).attr('id', $(this).attr('id') + "-" + parentId);
            $(this).next('label').attr('for', newId);
        });
        });
});

$(document).on('change', 'input[type="radio"]', function (e) {
        console.log($(this).parent().attr('id'));
});
