AngularJS ng-pluralize用法及代码示例

AngularJS中的ng-pluralize指令用于根据en-us本地化规则指定要显示的消息。 en-us本地化规则与AngularJS捆绑在一起。 AngularJS中的默认复数类别为“one”和“other”。

用法:

<ng-pluralize count="" when="string" [offset="number"]>
Contents...
</ng-pluralize>

参数值：

count:它指的是Angular表达式使用的count属性的值。
when:它用于指定实际字符串和复数类别之间的映射。该属性值必须为JSON对象样式。
offset:它指定要从总数中扣除的偏移量属性。

范例1：本示例使用ng-pluralize指令显示内容。

    <div ng-controller="geek"> 
        <div ng-init="Hotel=[0, 1, 2, 3]">

        app.controller('geek', ['$scope', function ($scope) { 
            $scope.booking = 0;
