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：

 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。
