需要在 angular ui select 中添加多个过滤器

Question

需要在 angular 中添加多个过滤器 uiselect2.

<div class="form-group ">
    <ui-select id="abc" ng-model="abc" multiple theme="bootstrap"  >
       <ui-select-match placeholder="Select abc..." class="ui-select-match">{{$item.name | capitalize}}</ui-select-match>
        <ui-select-choices id= "abchoice" class="ui-select-choices" repeat="item in itemDetails| filter: $select.search ">
               <div id="selected_{{item}}" ng-bind-html="item .name | capitalize | highlight: $select.search" style="padding: 0px; "></div>
         </ui-select-choices>
     </ui-select>

</div>

我有

itemDetails=["a","b","c"]
orderItem=["c"]

我还需要按 filter: $select.search 以及 orderItem 对其进行过滤。如何在ui-select中添加这个自定义过滤器？

在下拉菜单中，我应该只得到 a、b，我应该过滤 c

Answer 1

尝试类似的东西

var app = angular.module('demo', ['ui.select']);
app.controller('DemoCtrl', function($scope) {

  $scope.itemDetails = ['a','b','c'];
  $scope.orderItem = {};
  $scope.orderItem.items = ['a','b']; // by default selected items

});

在您看来

<ui-select multiple ng-model="orderItem.items" theme="select2" ng-disabled="disabled" style="width: 300px;">
   <ui-select-match placeholder="Select order item...">{{$item}}</ui-select-match>
    <ui-select-choices repeat="item in itemDetails | filter:$select.search">
      {{item}}
    </ui-select-choices>
 </ui-select>
  <p>Selected: {{orderItem.items}}</p>

使用过滤器排除项目

控制器：

 'use strict';
    var app = angular.module('demo', ['ui.select']);
    app.controller('DemoCtrl', function($scope) {
      $scope.itemDetails = ['a','b','c'];
      $scope.orderItem = {};
      $scope.orderItem.items = null;
    });
  // filter to exclude a value/item
  app.filter('Exclude', function() {
      return function( items) {
        var filtered = [];
        angular.forEach(items, function(item) {
          if(item!='c'){
            filtered.push(item);
          }
        });
        return filtered;
      };          
 });

查看：

<p>Selected: {{orderItem.items}}</p>
  <ui-select ng-model="orderItem.items" theme="select2" ng-disabled="disabled" style="width: 300px;">
    <ui-select-match placeholder="Select order item...">{{$select.selected}}</ui-select-match>
    <ui-select-choices repeat="item in itemDetails | Exclude |  filter:$select.search">
      {{item}}
    </ui-select-choices>
  </ui-select>

如果您需要从列表中筛选出您的 orderItem，请将它们删除到此列表中。

您应该有 3 个列表：

allItems（将所有项目存储在某处）
订单商品
itemsInSelect

当您 select itemsInSelect 中的一项时，将其添加到 orderItems 并将其从 itemsInSelect 中删除。
