当我在搜索字段中输入内容并且没有匹配时,我只想显示“无结果”消息.
目前,过滤器工作,但是当我键入不给出结果的关键字时,它不显示
“无结果”信息.怎么做?

<div class="portfolio-list-wrap" ng-controller="LatestProjectCtrl"> <input type="text" ng-model="search.$"/> <div class="portfolio-thumb" ng-repeat="work in works.project | filter:search"> <img src="images/{{work.string}}.jpg" alt="{{work.name}}"/> <h4>{{work.name}}</h4> <i>{{work.date}}</i> </div> </div>
这里是我做了我的工厂
var myApp = angular.module('myApp',[]); myApp.factory('Works',function(){ var Works = {} Works.project =[ { name : "project1",string : "projectstring1",date: "17 August 2012" },{ name : "project2",string : "projectstring2",date: "12 December 2013" },{ name : "project3",string : "projectstring3",date: "17 September 2012" },string : "projectstring4",]; return Works; }) function LatestProjectCtrl($scope,Works){ $scope.works = Works; }@H_403_10@
解决方法
您可以显示一条消息,表示没有这样的结果:
<span ng-show="(projects | filter:query).length == 0">No results</span>
有关完整的示例,请参阅下面的代码片段:
function Ctrl($scope) { $scope.projects = [ { name: "Sunny project 1",date: "17.3.2016",image: "pr1" },{ name: "Windy project 2",date: "18.03.2016",image: "pr2" },{ name: "Cloudy project 3",date: "19.03.2016",image: "pr3" } ] }
