Question

我正试图让我的{{client.tenant}}成为稍后过滤掉我的表格的来源。该表应仅根据我的下拉列表中的选择查看客户1或客户2。我感觉下拉列表中的输入没有存储在任何地方。你有什么提示我做错了吗？ down是我代码中的一个示例。我测试了很多，很抱歉代码。:)）

    <div class="container" ng-controller="menuController">

Answer 1

您只需更改以下代码

即可

 <select>
   <option ng-model="dropdownString" ng-repeat="client in products | unique:'tenant'">{{client.tenant}}</option>
  </select>

到

 <select ng-model="dropdownString" >
     <option ng-repeat="client in products | unique:'tenant'">{{client.tenant}}</option>
  </select>

我不确定它是否会起作用。这就是我如何解决你的问题。我的代码如下：

<强> HTML

<input type="text" class="search" ng-model="searchx.sku" placeholder="Enter your search terms" />


<select ng-model="searchx.tenant">
    <option ng-repeat="client in products | unique:'tenant'">{{client.tenant}}</option>
</select>

<div class="tab-content">
    <ul class="media-list tab-pane fade in active">
        <div class="row row-content">
            <div class="col-xs-12">
               <ul class="media-list">
                        <li class="media">
                            <div class="media-left media-middle">
                            </div>
                            <div class="media-body">
                                <table>
                                    <tr>
                                        <th class="table-1">Product description</th>
                                        <th>SKU</th>
                                        <th>Tenant</th>
                                        <th>Select</th>
                                    </tr>
                                    <tr ng-repeat="product in products | filter: searchx">
                                        <td>{{product.description}}</td>
                                        <td>{{product.sku}}</td>
                                        <td>{{product.tenant}}</td>
                                        <td><input type="checkbox"></td>
                                    </tr>
                                </table>
                            </div>
                        </li>
                    </ul>
        </ul>
        </div>

<强> Angular.js

 var app = angular.module('productBackend', []);

 app.controller('menuController', function ($scope, $http) {

       $scope.searchx = {};   

        $scope.search=[];
        $http.get('./products.json')
            .then(function (res) {
                $scope.products = res.data;
            });  
 });


 app.filter('unique', function() {
        // same code
 });

 app.controller('ExampleController', ['$scope', function($scope) {
     // same code
 }]);

过滤下拉列表中的所选项目
