VueJS 组件，不能覆盖类 [英] VueJS Component, can't override class

问题描述

我正在尝试覆盖我的 VueJS 组件的某个实例，但是由于某种原因，该组件仍在使用默认值.

i'm trying to over-ride a certain instance of my VueJS Component, however for some reason the component is still using the default value.

我试图覆盖的值是 buttonClass.其他道具似乎工作正常，所以不太确定为什么这个道具不起作用.

The value i'm trying to over-ride is the buttonClass. The other props seem to work fine, so not too sure as to why this one isn't working.

实例:

<delete-button buttonClass="is-info" csrf="{{ csrf_token() }}" action="redirects/delete-all"
               text="Delete All" body="This will delete ALL redirects"></delete-button>

组件:

<template>
    <form v-bind:action="action" method="post" @submit.prevent="confirm($event)">
        <input type="hidden" name="_token" v-model="csrf">
        <input type="hidden" v-model="id" name="id-value">
        <button type="submit" :class="['button is-link', buttonClass]">
            <i class="fas fa-trash-alt"></i>
            <span v-html="text"></span>
        </button>
    </form>
</template>
<script>
    export default {
        props: {
            'id': {},
            'csrf': {},
            'action': {},
            'buttonClass': {
                default: 'is-danger'
            },
            'text': {
                default: 'Delete'
            },
            'title': {
                default: 'Are you sure?'
            },
            'body': {
                default: ''
            }
        }
        // etc
    }
</script>

推荐答案

根据这一切的组合方式，模板中的 props 有时需要采用 kebab-cased，即

Depending on how this is all put together, props in the template are sometimes required to be kebab-cased, ie

<delete-button button-class="is-info" ...

参见 https://vuejs.org/v2/guide/components-props.html#Prop-Casing-camelCase-vs-kebab-case

HTML 属性名称不区分大小写，因此浏览器会将任何大写字符解释为小写.这意味着当你使用 in-DOM 模板时，camelCased prop 名称需要使用它们的 kebab-cased(连字符分隔)等价物

HTML attribute names are case-insensitive, so browsers will interpret any uppercase characters as lowercase. That means when you’re using in-DOM templates, camelCased prop names need to use their kebab-cased (hyphen-delimited) equivalents

仅供参考，单文件组件确实使用in-DOM 模板".

FYI, single-file components do use "in-DOM templates".
