AngularJS过滤器

AngularJS过滤器

过滤器可以使用一个管道字符（|）添加到表达式和指令中。

uppercase(变为大写):

<div ng-app="myApp" ng-controller="personCtrl">

<p>姓名为 {{ lastName | uppercase }}</p>

</div>

lowercase(变为大写):

<div ng-app="myApp" ng-controller="personCtrl">

<p>姓名为 {{ lastName | lowercase }}</p>

</div>

currency 过滤器将数字格式化为货币格式：

 1 <div ng-app="myApp" ng-controller="costCtrl">
 2 
 3 数量: <input type="number" ng-model="quantity">
 4 价格: <input type="number" ng-model="price">
 5 
 6 <p>总价 = {{ (quantity * price) | currency }}</p>
 7 
 8 </div>
 9 
10 <script>
11 var app = angular.module('myApp', []);
12 app.controller('costCtrl', function($scope) {
13     $scope.quantity = 1;
14     $scope.price = 9.99;
15 });
16 </script>

orderby(排序):

 1 <div ng-app="myApp" ng-controller="namesCtrl">
 2 
 3 <p>循环对象:</p>
 4 <ul>
 5   <li ng-repeat="x in names | orderBy:'name'">
 6     {{ x.name + ', ' + x.country }}
 7   </li>
 8 </ul>
 9 
10 </div>
11 
12 <script >
13     var app =  angular.module("myApp", []);
14     app.controller('namesCtrl', function($scope){
15         $scope.names = [
16             {name:"longjiang1",country:"３"},
17             {name:"longjiang2",country:"１"},
18             {name:"longjiang3",country:"２"}
19         ];
20     });
21     </script>

过滤输入

输入过滤器可以通过一个管道字符（|）和一个过滤器添加到指令中，该过滤器后跟一个冒号和一个模型名称。

filter 过滤器从数组中选择一个子集：

<div ng-app="myApp" ng-controller="namesCtrl">

<p>输入过滤:</p>

<p><input type="text" ng-model="test"></p>

<ul>
  <li ng-repeat="x in names | filter:test | orderBy:'country'">
    {{ (x.name | uppercase) + ', ' + x.country }}
  </li>
</ul>

</div>
<script>
angular.module('myApp', []).controller('namesCtrl', function($scope) {
    $scope.names = [
        {name:'Jani',country:'Norway'},
        {name:'Hege',country:'Sweden'},
        {name:'Kai',country:'Denmark'}
    ];
});
</script>
