AngularJS ng-pluralize用法及代碼示例

AngularJS中的ng-pluralize指令用於根據en-us本地化規則指定要顯示的消息。 en-us本地化規則與AngularJS捆綁在一起。 AngularJS中的默認複數類別為“one”和“other”。

用法:

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

參數值：

count:它指的是Angular表達式使用的count屬性的值。
when:它用於指定實際字符串和複數類別之間的映射。該屬性值必須為JSON對象樣式。
offset:它指定要從總數中扣除的偏移量屬性。

範例1：本示例使用ng-pluralize指令顯示內容。

<!DOCTYPE html> 
<html> 
  
<head> 
    <title>ng-pluralize Directive</title> 
      
    <script src= 
"https://ajax.googleapis.com/ajax/libs/angularjs/1.4.2/angular.min.js">

</head> 
  
<body ng-app="app" style="padding:20px">

    <h2 style="">ng-pluralize Directive</h2> 
      
    <div ng-controller="geek"> 
        <div ng-init="Hotel=[0, 1, 2, 3]"> 
            Choose from list:  
            <select ng-model="booking" ng-options= 
                "booking as booking for booking in Hotel">

            </ng-pluralize> 
        </div> 
    </div> 
      
    <script> 
        var app = angular.module("app", []); 
        app.controller('geek', ['$scope', function ($scope) { 
            $scope.booking = 0; 
        }]);
