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
