答案 0 :(得分：1)
您的问题是您正在尝试在ng-repeat内的html模板中分配范围变量。 ng-repeat为每个项创建一个嵌套范围，因此赋值仅在该内部范围内发生。
要解决此问题，请确保您指定的名称至少包含一个点.。一种简单的方法是切换代码以使用＆＃39;控制器作为＆＃39;语法，然后您可以直接引用所需的控制器。另一种方法是将范围变量推送到对象内而不是直接放在范围内。
<body ng-app="app" ng-controller="Ctrl as vm">
<zc-select status-var="vm.CountryOpen">
<div class="select-head">
Select a country
</div>
<ul class="select-content" ng-show="vm.CountryOpen">
<li ng-repeat="i in vm.countries" id="{{i.code}}" ng-click="vm.CountryOpen = false">{{i.name}}</li>
</ul>
</zc-select>
</body>
然后更新您的控制器以使用this而不是$scope：
app.controller('Ctrl', [function() {
var vm = this;
vm.CountryOpen = false;
vm.Country = [];
vm.countries = [
...
（我将ng-init的东西推入控制器，因为尽可能多地保存代码并保持html尽可能干净）
