未知提供者:uniqueAngleProvider在Angular.js中使用唯一过滤器

问题描述

限时删除！！

我是AngularJS的新手.我正在尝试实施过滤，以为选择框构建唯一的选项列表.我的代码如下

I am new to AngularJS. I am trying to implement filtering to build a unique list of options for the select box. My code is as follows

<select name="show-filter" id="show-filter" ng-model="card" ng-options="v for v in currentOptions.cards  | unique:'cardno'">
<option value="">All</option>
</select>

我遇到以下错误

示例JSON(包装为$scope.currentOptions)

sample JSON (wrapped into $scope.currentOptions)

"cards ":[{"cardno":"123223333"},{"cardno":"123223333"},{"cardno":"123223333"}]}

推荐答案

AngularJS没有内置的unique过滤器.您可能正在寻找名为 AngularUI 的第三方附加库，它确实具有这种过滤器.

AngularJS does not have a built-in unique filter. You may be looking for the third-party add-on library called AngularUI that does have such a filter.
