需要在angular ui select中添加多个过滤器 [英] Need to add multiple filter in angular ui select

问题描述

需要在angular uiselect2中添加多个过滤器.

<ui-select id="abc" ng-model="abc" 多个主题="bootstrap" ><ui-select-match placeholder="选择 abc..." class="ui-select-match">{{$item.name |大写}}</ui-select-match><ui-select-choices id="abchoice" class="ui-select-choices" repeat="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>

我有

itemDetails=["a","b","c"]订单项=[c"]

而且我需要通过 filter: $select.search 也通过 orderItem 过滤它.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

解决方案

尝试类似的事情

var app = angular.module('demo', ['ui.select']);app.controller('DemoCtrl', function($scope) {$scope.itemDetails = ['a','b','c'];$scope.orderItem = {};$scope.orderItem.items = ['a','b'];//默认选中的项目});

在你看来

<ui-select-match placeholder="选择订单项目...">{{$item}}</ui-select-match><ui-select-choices repeat="itemDetails 中的项目 | filter:$select.search">{{物品}}</ui-select-choices></ui-select><p>已选择:{{orderItem.items}}</p>

使用过滤器排除项目

控制器:

 '使用严格';var app = angular.module('demo', ['ui.select']);app.controller('DemoCtrl', function($scope) {$scope.itemDetails = ['a','b','c'];$scope.orderItem = {};$scope.orderItem.items = null;});//过滤以排除值/项目app.filter('排除', function() {返回函数(项目){var 过滤 = [];angular.forEach(项目，功能(项目){如果(项目！='c'){过滤.推(项目)；}});返回过滤；};});

查看:

已选择:{{orderItem.items}}
<ui-select ng-model="orderItem.items" theme="select2" ng-disabled="disabled" style="width: 300px;"><ui-select-match placeholder="选择订单项...">{{$select.selected}}</ui-select-match><ui-select-choices repeat="itemDetails 中的项目 | 排除 | filter:$select.search">{{物品}}</ui-select-choices></ui-select>

Need to add multiple filter in angular 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>

I have

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

And I need to filter it by filter: $select.search also by orderItem. How to add this custom filter in ui-select?

IN dropdown I shoud get only a, b, i should filter c

解决方案

Try something like that

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

});

In your view

<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>

Exclude an Item using a filter

Controller:

 '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;
      };          
 });

View:

<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>
