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()
