我已经尝试过但无法让它发挥作用我确定它是因为它无法返回并获得我已经尝试了一段时间的价格价值

我已经尝试了我所知道的一切，但我对此很陌生

我希望外部角输出一个值，也可以在未选中时以更改值的形式输出。

您的代码不是很简单，有硬编码值和一些问题。

首先简化并干燥代码——我myApp为东西创建了一个命名空间（）以避免全局变量，这通常是不好的。然后，我将数据移到数据对象中，并从您设置的复杂 if/else if/else 中移出，并将其简化为使用该数据的简单调用。注意现在pricesRanges保存值更改的范围，因此更易于维护并且也没有嵌入代码中，因此您可以添加调整和删除范围而无需更改逻辑，因为它现在使用该lookUpMatch函数来查找它。

我调整了动画以简化并从它们中制作了一个。为了简化这一点，我使用例如为目标设置数据属性targetindex="1"，为了方便起见，我添加了一个类，以便如果您将标记从 a 更改fieldset为其他内容，它仍然可以使用field-group.

var myApp = myApp || {
  pricesRanges: [{
    range: 0,
    bags: 0
  }, {
    range: 10,
    bags: 1
  }, {
    range: 40,
    bags: 2
  }, {
    range: 70,
    bags: 3
  }, {
    range: 80,
    bags: 3
  }, {
    range: 100,
    bags: 4
  }, {
    range: 130,
    bags: 5
  }, {
    range: 160,
    bags: 6
  }, {
    range: 190,
    bags: 7
  }, {
    range: 220,
    bags: 8
  }, {
    range: 250,
    bags: 9
  }, {
    range: 280,
    bags: 10
  }, {
    range: 290,
    bags: 10
  }, {
    range: 390,
    bags: 10
  }],
