📖 规则详情

此规则报告未使用 emits 选项声明的事件触发器。（emits 选项是 Vue.js 3.0.0+ 中的新增选项）

¥This rule reports event triggers not declared with the emits option. (The emits option is a new in Vue.js 3.0.0+)

显式 emits 声明用作自文档代码。这对于其他开发者很有用，可以让他们立即了解组件应该触发什么事件。此外，随着 Vue.js 3.0.0+ 中属性 fallthrough 的变化，组件上的 v-on 监听器将默认作为原生监听器 fallthrough。在 emits 中将其声明为仅限组件的事件，以避免不必要地注册原生监听器。

¥Explicit emits declaration serves as self-documenting code. This can be useful for other developers to instantly understand what events the component is supposed to emit. Also, with attribute fallthrough changes in Vue.js 3.0.0+, v-on listeners on components will fallthrough as native listeners by default. Declare it as a component-only event in emits to avoid unnecessary registration of native listeners.
