AngularJS: API: ng/filter/orderBy

orderBy

  1. - filter in module ng

通过expression来排序指定的array 。 字符串按字母顺序排序，数字按大小排序。注意：如果你发现数字没被正确排序，请确认它们保存的是数字而不是字符串。

用法

用于HTML模板绑定

{{ orderBy_expression | orderBy : expression : reverse}}

用于JavaScript

$filter('orderBy')(array, expression, reverse)

参数

参数 类型 详述
array Array

用于排序的数组。
expression function(*)stringArray.<(function(*)|string)>

一个用于通过比较来决定元素顺序的声明。

可为下列之一：

  • Function: Getter函数。这个函数的结果可使用 <, =, >操作符进行排序。
  • string: 一个Angular表达式，对一个对象求值来排序，如用'name'来对属性名为'name'排序。用可选前缀 + 或 -来确定是正序或倒序 (例如，+name or -name)。
  • Array: 一个函数或字符串声明数组。数组中的第一个声明用于排序，但是当两个条目相等时，会用下一个声明。
reverse
(可选)
 boolean

对数组进行反向排序。

返回值

Array

源数组排序后的副本。

示例

index.html
<script>
  angular.module('orderByExample', [])
    .controller('ExampleController', ['$scope', Function($scope) {
      $scope.friends =
          [{name:'John', phone:'555-1212', age:10},
           {name:'Mary', phone:'555-9876', age:19},
           {name:'Mike', phone:'555-4321', age:21},
           {name:'Adam', phone:'555-5678', age:35},
           {name:'Julie', phone:'555-8765', age:29}];
      $scope.predicate = '-age';
    }]);
</script>
<div ng-controller="ExampleController">
  <pre>Sorting predicate = {{predicate}}; reverse = {{reverse}}</pre>
  <hr/>
  [ <a href="" ng-click="predicate=''">unsorted</a> ]
  <table class="friend">
    <tr>
      <th><a href="" ng-click="predicate = 'name'; reverse=false">名称</a>
          (<a href="" ng-click="predicate = '-name'; reverse=false">^</a>)</th>
      <th><a href="" ng-click="predicate = 'phone'; reverse=!reverse">Phone Number</a></th>
      <th><a href="" ng-click="predicate = 'age'; reverse=!reverse">Age</a></th>
    </tr>
    <tr ng-repeat="friend in friends | orderBy:predicate:reverse">
      <td>{{friend.name}}</td>
      <td>{{friend.phone}}</td>
      <td>{{friend.age}}</td>
    </tr>
  </table>
</div>

也可以手工调用orderBy过滤器，通过注入$filter，使用$filter('orderBy')获取过滤器实例，然后使用所需参数调用过滤器实例。

示例:

index.html
<div ng-controller="Ctrl">
  <table class="friend">
    <tr>
      <th><a href="" ng-click="reverse=false;order('name', false)">名称</a>
        (<a href="" ng-click="order('-name',false)">^</a>)</th>
      <th><a href="" ng-click="reverse=!reverse;order('phone', reverse)">Phone Number</a></th>
      <th><a href="" ng-click="reverse=!reverse;order('age',reverse)">Age</a></th>
    </tr>
    <tr ng-repeat="friend in friends">
      <td>{{friend.name}}</td>
      <td>{{friend.phone}}</td>
      <td>{{friend.age}}</td>
    </tr>
  </table>
</div>
script.js
angular.module('orderByExample', [])
  .controller('ExampleController', ['$scope', '$filter', Function($scope, $filter) {
    var orderBy = $filter('orderBy');
    $scope.friends = [
      { name: 'John',    phone: '555-1212',    age: 10 },
      { name: 'Mary',    phone: '555-9876',    age: 19 },
      { name: 'Mike',    phone: '555-4321',    age: 21 },
      { name: 'Adam',    phone: '555-5678',    age: 35 },
      { name: 'Julie',   phone: '555-8765',    age: 29 }
    ];
    $scope.order = Function(predicate, reverse) {
      $scope.friends = orderBy($scope.friends, predicate, reverse);
    };
    $scope.order('-age',false);
  }]);
