Question

下午好，

我们目前正在尝试学习AngularJS，虽然我们正在寻找一些非常酷的代码，但我们似乎无法解决这个问题。

我们希望在下拉列表功能中显示相对于所选产品的产品选项列表，我们希望能够在每行上勾选一个单选按钮，但是当我们勾选其中一个单选按钮时似乎是在每个栏目中选择所有。

我们附上了我们的代码段和屏幕截图，如果有人可以帮助我们，我们会非常感激。

谢谢。 原始Plnkr http://embed.plnkr.co/bpMoLNnf4zs5VK4kx1JJ/preview

Answer 1

查看代码后，您的问题是您在每个重复周期中将单选按钮绑定到同一对象。

让我们看一下目前正在发生的事情，首先你有一个ng-repeat正在重复$ scope.visualItems中的html部分，它正在按预期工作。但是，如果你看一下用于绑定单选按钮选择的ng-model：

 <input type="radio" name="{{visualItem.id}}" 
        ng-model="formData.visualItems.one"
        ng-value="visualItem.one"/>

在每次重复中，ng-model被绑定到相同的值，因此当你选择一个单选按钮时，重复中的每个其他部分都会改变，这就是双向绑定应该起作用的方式。

要解决此问题，您需要将每个单选按钮绑定到一个唯一的模型，我建议在列表中创建一个重复的选定属性，以便每个单选按钮都可以绑定到它自己的唯一值。

你可以做的一件事，就是不知道代码中的完整过程，就是将单选按钮绑定到一个 - 两个 - 并更改这些值布尔值。如果你知道每一个都有相应的颜色，可能需要存储在列表中，你可以这样做。这只是一个建议。

您还可以重构对象，因此每一个 - 两 - 三个是具有isSelected属性和颜色值的对象。

one: {color:'red', isSelected: false}

然后在你的ngrepeat中你可以这样做：

input type="radio" name="{{visualItem.id}}" 
      ng-model="visualItem.one.isSelected"
      ng-value="visualItem.one"/>

Answer 2

我认为问题在于将您的单选按钮绑定到同一个ng模型。

第一个建议：将单选按钮绑定到不同的模型

NG-模型= “visualItem.three”

每组

。首先选择所有项目，然后它将正常更改。这样：

<div ng-show="product.name=='Petrol Lawnmower'">
    <div ng-repeat="visualItem in visualItems">
        <label for="">{{visualItem.name}}</label>
        <input type="radio" ng-value="visualItem.one" name="{{visualItem.id}}" ng-model="visualItem.one" />
        <input type="radio" ng-value="visualItem.two" name="{{visualItem.id}}" ng-model="visualItem.two" />
        <input type="radio" ng-value="visualItem.three" name="{{visualItem.id}}" ng-model="visualItem.three" />
    </div>
</div>

第二个建议：是删除ng-model并使用常规的javascript函数获取数据

第三个建议：在选择选项时使用ng-change来编写表达式
