【Angular】过滤器

AngularJS学习笔记

 

{{ name | uppercase}}
{{ 123.456789 | number:2 }}

app.controller('DemoController', ['$scope', '$filter', function($scope, $filter) {
    $scope.name = $filter('lowercase')('Ari')
}])

 

过滤器也可以带参数，多个参数之间使用:分割

<!DOCTYPE html>
<html ng-app="Demo">
<head>
    <meta charset="utf-8">
    <title></title>
</head>
<body>
   <script src="jquery-1.8.3.min.js"></script>
   <script src="angular.min.js"></script>
   <div ng-controller="TestCtrl">
       <p>示例数据: {{ a|map:map_value:'&gt;&gt;':'(no)' }}</p>
       <p>示例数据: {{ b|map:map_value:'&gt;&gt;':'(no)' }}</p>
   </div>
   <script>
        var app = angular.module('Demo', [], angular.noop)
        app.controller('TestCtrl', function($scope) {
            $scope.map_value = {
                a: '一',
                b: '二',
                c: '三'
            }
            $scope.a = 'a'
        })

        app.filter('map', function() {
            var filter = function(input, map_value, append, default_value) {
                console.log(input, map_value, append, default_value)
                var r = map_value[input]
                if (r === undefined) {
                    return default_value + append
                } else {
                    return r + append
                }
            }
            return filter
        })
   </script>
</body>
</html>
