ng-switch不适合我

Question

我无法理解为什么ng-switch对我不起作用。似乎我做了应该做的一切。

没有显示带有ng-switch指令的DIV。很可能我在ng-switch-when中输入了错误的值，但我不知道如何修复它。

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>

Answer 1

而不是使用$parent使用范围中定义的对象，如$scope.outerScope

 <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$parent

中删除<div ng-switch on="selectedSizeSwitch">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，这就是您需要在那里使用$parent而不是在交换机中的原因。

第二个http://codepen.io/mkl/pen/YWZwLj

的示例

对于两者，您需要将<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。
