AngularJS 全局 API 用于执行常见任务的 JavaScript 函数集合,如:
全局 API 函数使用 angular 对象进行访问。
以下列出了一些通用的 API 函数:
API | 描述 |
---|---|
angular.lowercase() | 转换字符串为小写 |
angular.uppercase() | 转换字符串为大写 |
angular.isString() | 判断给定的对象是否为字符串,如果是返回 true。 |
angular.isNumber() | 判断给定的对象是否为数字,如果是返回 true。 |
angular.lowercase()
<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()
<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()
<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>
<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>
