关于angular事件问题？

[ipbear]

我看一篇教程中使用了很多事件，这些事件是属于angular的吗，在说明的哪一部分那？

例如：（change）,(keyup) ,(keydown),completed,editing,

/**
 * This array represents the DOM schema. It encodes inheritance, properties, and events.
 *
 * ## Overview
 *
 * Each line represents one kind of element. The `element_inheritance` and properties are joined
 * using `element_inheritance|properties` syntax.
 *
 * ## Element Inheritance
 *
 * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
 * Here the individual elements are separated by `,` (commas). Every element in the list
 * has identical properties.
 *
 * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
 * specified then `""` (blank) element is assumed.
 *
 * NOTE: The blank element inherits from root `[Element]` element, the super element of all
 * elements.
 *
 * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
 *
 * ## Properties
 *
 * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
 * by a special character designating its type:
 *
 * - (no prefix): property is a string.
 * - `*`: property represents an event.
 * - `!`: property is a boolean.
 * - `#`: property is a number.
 * - `%`: property is an object.
 *
 * ## Query
 *
 * The class creates an internal squas representation which allows to easily answer the query of
 * if a given property exist on a given element.
 *
 * NOTE: We don't yet support querying for types or events.
 * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
 *       see dom_element_schema_registry_spec.ts

上面的那个出自ng源码, 你可以理解为带*的就是事件^的意思就是继承,比如 'h1,h2,h3,h4,h5,h6^[HTMLElement]|align',继承了[HTMLElement],HTMLElement里面就有好多的事件 如果还理解困难可以新建一个Ng项目,在node_modules里面给这个文件下断点,他会在运行时做一个转换

如果你不是想了解内部工作原理，可以简单的理解成：凡是原生事件，都可以通过 (事件名) 的形式进行事件绑定。属性绑定同理。
