我正尝试在一个VueJS项目中使用VueStrap,看起来webpacker可以很好地加载它,我可以在终端输出中看到这一点,但是,当我尝试使用vue-strap中的组件时,我得到了这个错误:
[Vue warn]: Property or method "input" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based componen
我在浏览器Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "dataElements"中不断收到此错误 我的组件中有@Prop() private dataElements: any[];。这个道具是由父级和子级更改的,当它更改
我对VueJS很陌生。在“反应”中,您可以很容易地使用rest将道具传递给儿童。Vue有类似的模式吗?
考虑这个父组件,它有几个子组件:
<template>
<header class="primary-nav">
<search-bar :config="searchBar"><search-bar>

<html>
<head>
<ti

<div class="alert alert-info" v-if="userAdded">
User was created!
</div>
或者,如果没有,我可以访问子组件的变量吗?
<div class="alert alert-info" v-if="$refs.addView.form.successful">

我遵循一个带有Hooks在线课程的Advanced模式,在这个早期的例子中,他们用以下API创建了一个可扩展组件(比如经典的手风琴或可折叠面板):
<Expandable>
<Expandable.Header>This is the header</Expandable.Header>
<Expandable.Body>This is the content</Expandable.Body>
</Expandable>
他们使用上下文将州expanded传递给可扩展的孩子。到目前为止还不错:
