ng-switch 不适合我

Question

我不明白为什么 ng-switch 不适合我。看来我所做的一切都是应该的。

带有 ng-switch 指令的 DIV 未显示。很可能我在 ng-switch-when 中输入了错误的值，但我无法理解如何修复它。

Here is my code

<div class="row">
    <div class="col-xs-12 col-sm-6">Размер дверной коробки
        <div class='input' ng-repeat="a in sizeswitch">
            <input type="radio" name='radio' ng-model="$parent.selectedSizeSwitch" ng-value="a.desc" id="@{{a.value}}">
            <label for="{{a.value}}">{{a.label}}</label>
        </div>
    </div>

   <div ng-switch on="$parent.selectedSizeSwitch">
    <div class="col-xs-12 col-sm-6" ng-switch-when="Стандартный">Стандартные размеры дверной коробки (мм)
        <div class="custom-dropdown custom-dropdown--white">
            <select ng-model="selectedStandardSize" ng-options="b.label for b in standardsizes" class="standard_sizes custom-dropdown__select custom-dropdown__select--white"></select>
        </div>
    </div>

    <div class="col-xs-12 col-sm-6" ng-switch-when="Ввести размер">Нестандартные размеры дверной коробки
        <div class='input'>
            <input name="door_size_b" id="input1" type="text" ng-model="DoorSizeB" placeholder=""><label for="door_size_b">Ширина дверной коробки, мм</label>
        </div>

        <div class='input'>
            <input name="door_size_h" id="input2" type="text" ><label for="door_size_h">Высота дверной коробки, мм</label>

Answer 1

不要使用$parent，而是使用在$scope.outerScope这样的范围内定义的对象

 <input type="radio" name='radio' ng-model="outerScope.selectedSizeSwitch" 
           ng-value="a.desc" id="@{{a.value}}">

并在控制器中将其初始化为空对象

$scope.outerScope = {};

这是一个工作示例http://codepen.io/mkl/pen/oLZbYo

您也可以通过从 <div ng-switch on="selectedSizeSwitch"> 中删除 $parent 来解决此问题

您遇到的问题是 ng-repeat 的范围，重复中的每个项目都在创建自己的范围，这就是为什么您需要在那里使用 $parent 而不是在开关中使用。

第二个http://codepen.io/mkl/pen/YWZwLj的例子

对于两者，您都需要将<div class="col-xs-12 col-sm-6" ng-switch-when="Ввести размер"> 更新为<div class="col-xs-12 col-sm-6" ng-switch-when="Нестандартный">，它正在寻找错误的值。
