Angular 有哪些未公开的特性? [英] What are the undocumented features of Angular?

问题描述

Angular 文档缺少一些东西.有人可以总结一下未记录的功能是什么吗?

The Angular documentation is missing a few things. Can someone summarize what the undocumented features are?

推荐答案

Angular 1.0.5 和 1.0.4:

• Scope 有两个有用的未记录属性:

• Scope has two useful undocumented properties:

1. $parent - 可以用作绑定到父作用域中的原始属性的技巧 - 例子
2. $$phase - 可用于确定 $digest 是否已在进行中 - 请参阅 this所以答案

1. $parent - can be used as a hack for binding to a primitive property in a parent scope - example
2. $$phase - can be used to determine if a $digest is already in progress - see this SO answer

ng-switch 有一个未记录的更改 接受表达式的参数(example plnkr)

select 有一个未记录的 ng-change 接受表达式的参数

属性 有一个未记录的 $观察 方法(虽然在指令页面上有提到)

$cacheFactory 有两个未公开的方法(示例小提琴)

ng-switch has an undocumented change parameter that accepts an expression (example plnkr)

select has an undocumented ng-change parameter that accepts an expression

Attributes has an undocumented $observe method (although it is mentioned on the Directives page)

$cacheFactory has two undocumented methods (example fiddle)

1. get()
2. info()

$location 服务有两个未记录的事件

the $location service has two undocumented events

1. $locationChangeStart(evt, newUrl, oldUrl)(示例)
2. $locationChangeSuccess(evt, newUrl, oldUrl)(另见 $locationChangeSuccess 和 $locationChangeStart 之间有什么区别?)

1. $locationChangeStart(evt, newUrl, oldUrl) (example)
2. $locationChangeSuccess(evt, newUrl, oldUrl) (see also What's the difference between $locationChangeSuccess and $locationChangeStart?)

使用带有 input type="radio" 的 ng-value(未记录)，参见 Disqus 评论在 API 文档中
