下面是完整的错误我得到的角UI选

Here is the full error I get in angular ui-select

Error: [$interpolate:interr] Can't interpolate: {{$select.getPlaceholder()}} TypeError: Cannot read property 'length' of undefined

我的标记是：

  <ui-select multiple ng-model="case.keywords" theme="bootstrap">
    <ui-select-match placeholder="Select keywords...">{{$item.name}}</ui-select-match>
    <ui-select-choices repeat="keywords in keywords | filter: $select.search">
      <div ng-bind-html="keyword.name | highlight: $select.search"></div>
    </ui-select-choices>
  </ui-select>
<p>Selected: {{case.keywords}}</p>

没有比 GET 其他控制器的特殊婷从数据库关键字的数组。显然 ngSanitize 和 ui.select 包含在模块依赖​​关系。

Nothing special in controller other than getting the array of keywords from db. Obviously ngSanitize and ui.select are included in the module dependencies.

另一个问题我是选择是不可见的。我可以显示所选的，但选择列表是不可见的。我使用的引导主题， select.css 引用。下面是它看起来像

The other issue I have is that choices are not visible. I am able to show the selected ones, but list of choices is not visible. I am using bootstrap theme, select.css is referenced. Here's what it looks like

感谢您的帮助。

推荐答案

这@SunilVurity和@Fiver问题给我，导致我解决问题的提示：

Questions from @SunilVurity and @Fiver gave me hints that lead me to resolve the issue:

第一我改变了关键字到中的关键字：

<ui-select-choices repeat="keywords in keywords | filter: $select.search">

二在我的控制器我有

appFactory.getKeywords().then(function (keywords){
  $scope.keywords = keywords;
  $scope.case = {};
  $scope.case.selectedKeywords = [];
});

这我更改为：

$scope.case = {};
$scope.keywords = [];
learningCasesFactory.getKeywords().then(function (keywords){
  $scope.keywords = keywords;
  $scope.case.selectedKeywords = [];
});

你可以在控制器中看到的， GET 函数是异步的，它返回一个未定义的列表，这引起我的问​​题提到的错误上载的看法。更新控制器的误差消失之后。这太问题帮助 AngularJS插值误差。

As you can see in the controller, the get function is asynchronous which returns an undefined list to the view on load which caused the error I mentioned in the question. After updating the controller the error disappeared. This SO question helped AngularJS Interpolation Error.

第三的 uiselect 和角版本可能导致的问题。我的角版本是1.2​​.9。这 UI的选择Github上的问题表明，升级版的角度解决问题，我把它升级到1.3.11

Third the uiselect and angular versions can cause issues. My angular version is 1.2.9. This ui-select Github issue shows that upgrading the angular version solves the issue, I upgraded it to 1.3.11
