在上面的代码中,我们定义了自定义事件customEvent;当该事件被触发时,就会调用customEvent后面定义的函数,打印出负载数据,同时,我们可以在customEvent函数中返回一个Boolean类型,对响应数据进行校验,如果返回false,数据校验不通过,会在控制台进行提示: [Vue warn]: Invalid event arguments: event validation failed for even...
[Vue warn]: Invalid event arguments: event validation failed for event "add". v-model 在以前的文章中,我们知道v-model指令是做双向数据绑定的,其实它也可以做父子组件通信的指令。 const app = Vue.createApp({data(){return {count: 1}},template: `<counter v-model="count" />`});app.component...

console.warn(`Invalid submit event payload!`) return false } } } 强烈建议使用emits记录每个组件所触发的所有事件,而且记录的事件会有代码提示。 渲染函数 统一插槽API 以前,在组件中获取插槽是两个不同的api(this.$scopedSlots和this.$slots),现在统一使用this.$slots。

Next the createUser event to be emitted was declared:const emit = defineEmits(['createUser'])Finally, the event and the arguments to it (form/field data) are prepared and emitted:const addNewUser = () => { emit('createUser', { name: user.value.name, username: user.value.username, ...
