AngularJS API



  • 全局 API

    AngularJS 全局API是一组用于执行常见任务的全局JavaScript函数,例如:
    • 比较对象
    • 迭代对象
    • 转换数据
    全局API函数是使用 angular 对象访问的。
    以下是一些常见的API函数的列表:
    API 描述
    angular.lowercase() 将字符串转换为小写
    angular.uppercase() 将字符串转换为大写
    angular.isString() 如果引用是字符串,则返回true
    angular.isNumber() 如果引用是数字,则返回true
  • angular.lowercase()

    下面示例演示了angular.lowercase()方法将字符串转换为小写:
    <div ng-app="myApp" ng-controller="myCtrl">
        <p>{{ x1 }}</p>
        <p>{{ x2 }}</p>
    </div>
    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function($scope) {
           $scope.x1 = "JOHN";
           $scope.x2 = angular.lowercase($scope.x1);
        });
    </script>
    
  • angular.uppercase()

    下面示例演示了angular.uppercase()方法将字符串转换为大写:
    <div ng-app="myApp" ng-controller="myCtrl">
        <p>{{ x1 }}</p>
        <p>{{ x2 }}</p>
    </div>
    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function($scope) {
        $scope.x1 = "John";
        $scope.x2 = angular.uppercase($scope.x1);
    });
    </script>
    
  • angular.isString()

    下面示例演示了angular.isString()方法如果引用是字符串,则返回true
    <div ng-app="myApp" ng-controller="myCtrl">
        <p>{{ x1 }}</p>
        <p>{{ x2 }}</p>
    </div>
    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function($scope) {
            $scope.x1 = "JOHN";
            $scope.x2 = angular.isString($scope.x1);
        });
    </script>
    
  • angular.isNumber()

    下面示例演示了angular.isNumber()方法如果引用是数字,则返回true
    <div ng-app="myApp" ng-controller="myCtrl">
        <p>{{ x1 }}</p>
        <p>{{ x2 }}</p>
    </div>
    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function($scope) {
            $scope.x1 = "JOHN";
            $scope.x2 = angular.isNumber($scope.x1);
        });
    </script>
