本文实例讲述了angularjs自定义过滤器demo。分享给大家供大家参考，具体如下：

这个基于angularjs的过滤器是最近做的"信息管理学院实验室预约"项目中的一个小功能。

以下为数据:

$scope['classes']=[{id:1,name:"H503",capacity:40,software:"photoshop,金蝶,AI",freeTime:"周一1-2-3,周五1-2-3,周一5-6,"},   {id:2,name:"H504",capacity:50,software:"chrome,金蝶,office,"   ,freeTime:"周二1-2-3,周三3-4,周一5-6,"},   {id:3,name:"H505",capacity:60,software:"chrome,LOL,office,"   ,freeTime:"周二1-2-3,周三3-4,周四7-8,"}];

具体功能:

分别在两个select选择星期和课次，列表会即时根据条件更新。

完整代码:

<!DOCTYPE html><html ng-app="myApp" ><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body><div ng-controller="myCtrl"> <select ng-model="day">  <option selected="">周一</option>  <option>周二</option>  <option>周三</option>  <option>周四</option>  <option>周五</option> </select>  <select ng-model="order">  <option selected="">1-2</option>  <option>1-2-3</option>  <option>3-4</option>  <option>1-2-3-4</option>  <option>5-6</option>  <option>7-8</option>  </select>  <ul>   <li ng-repeat="class in classes | myFiter:day:order">     <span>{{class.id}}</span>     <span>{{class.name}}</span>      <span>{{class.capacity}}</span>      <span>{{class.software}}</span>   </li>  </ul> </select></div><script type="text/javascript">var app = angular.module('myApp', []);app.controller('myCtrl', function($scope) { //假数据  $scope['classes']=[{id:1,name:"H503",capacity:40,software:"photoshop,金蝶，AI",freeTime:"周一1-2-3,周五1-2-3,周一5-6,"},   {id:2,name:"H504",capacity:50,software:"chrome,金蝶,office,"   ,freeTime:"周二1-2-3,周三3-4,周一5-6,"},   {id:3,name:"H505",capacity:60,software:"chrome,LOL,office,"   ,freeTime:"周二1-2-3,周三3-4,周四7-8,"}  ];  //select的默认值  $scope.order="1-2";  $scope.day="周一";});//自定义过滤器app.filter('myFiter',function(){ return function(input,day,order) {   var time=day+order;   var output=[];   for(var i=0;i<input.length;i++)   {   var n=input[i].freeTime.indexOf(time);   // console.log(n);   // console.log(input[i].freeTime.charAt(n+time.length));    if(n!=-1)//如果能找到    {     if(input[i].freeTime.charAt(n+time.length)==',')     //这样做是为了防止1-2与1-2-3是一样的结果      output.push(input[i]);    }   }   return output; }})</script></body></html>

运行效果：
