AngularJS中的API(接口)简单实现
AngularJS API
API 意为 Application Programming Interface(应用程序编程接口)。
AngularJS 全局 API
AngularJS 全局 API 用于执行常见任务的 JavaScript 函数集合,如:
比较对象
迭代对象
转换对象
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()
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <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> </body> </html>
运行结果:
JOHN
john
angular.uppercase()
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <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> </body> </html>
运行结果:
JOHN
true
angular.isString()
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <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> </body> </html>
运行结果:
JOHN
true
angular.isNumber()
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <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> </body> </html>
运行结果:
JOHN
false
以上就是对AngularJS API(接口)资料的整理,后续继续补充,希望能帮助编程的同学。
