AngularJS API

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 (<angular1.7) angular.$$lowercase()(angular1.7+) |
转换字符串为小写 |
angular.uppercase() (<angular1.7) angular.$$uppercase()(angular1.7+) |
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。 |
注意:自 AngularJS 1.7 之后移除 angular.lowercase 和 angular.uppercase 方法, 改为 angular.$$lowercase 和 angular.$$uppercase
angular.lowercase()
实例
<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 = "RUNOOB";
$scope.x2 = angular.$$lowercase($scope.x1);
});
</script>
<p>{{ x1 }}</p>
<p>{{ x2 }}</p>
</div> <script>
var app = angular.module(‘myApp’, []);
app.controller(‘myCtrl’, function($scope) {
$scope.x1 = "RUNOOB";
$scope.x2 = angular.$$lowercase($scope.x1);
});
</script>
angular.uppercase()
实例
<div ng-app="myApp" ng-controller="myCtrl">
<p>{{ x1 }}</p>
<p>{{ x2 }}</p>
</div>
<script>
var app = angular.module(‘myApp’, []);
app.controller(‘myCtrl’, function($scope) {
$scope.x1 = "runoob";
$scope.x2 = angular.$$uppercase($scope.x1);
});
</script>
<p>{{ x1 }}</p>
<p>{{ x2 }}</p>
</div>
<script>
var app = angular.module(‘myApp’, []);
app.controller(‘myCtrl’, function($scope) {
$scope.x1 = "runoob";
$scope.x2 = angular.$$uppercase($scope.x1);
});
</script>
angular.isString()
实例
<div ng-app=“myApp” ng-controller=“myCtrl”>
<p>{{ x1 }}</p>
<p>{{ x2 }}</p>
</div>
<p>{{ x1 }}</p>
<p>{{ x2 }}</p>
</div>
<script>
var app = angular.module(‘myApp’, []);
app.controller(‘myCtrl’, function($scope) {
$scope.x1 = “RUNOOB”;
$scope.x2 = angular.isString($scope.x1);
});
</script>
angular.isNumber()
实例
<div ng-app=“myApp” ng-controller=“myCtrl”>
<p>{{ x1 }}</p>
<p>{{ x2 }}</p>
</div>
<p>{{ x1 }}</p>
<p>{{ x2 }}</p>
</div>
<script>
var app = angular.module(‘myApp’, []);
app.controller(‘myCtrl’, function($scope) {
$scope.x1 = “RUNOOB”;
$scope.x2 = angular.isNumber($scope.x1);
});
</script>
