Laravel 和 VueJS : Calling a VueJS Method Inside Blade

Question

我是 Laravel 和 VueJS 的新手，对于困惑的代码提前深表歉意。

我一直在尝试制作一个注册表单，并将 VueJS 集成到 laravel 中以使其更具动态性。现在我一直在尝试使用 {{ }} 前面的 @ 来显示 laravel 我正在尝试集成 VueJS 但不是 VueJS 响应它只是清楚地打印:{{ error }} 或 {{ checked ? "is":“否”}}。

Blade

@extends('layout.layout')

@section('content')
    <section class="page-content">
        <div class="container">
            <article class="fillout-form">
                <form action="{{ route('account.register.new') }}" method="post" id="registerForm">
                    {{ csrf_field() }}
                    @{{ error }}
                    <section v-if="step === 1">

                        <h1>Step One</h1>
                        <p>
                            <legend for="name">Your Name:</legend>
                            <input id="name" name="name" v-model="registration.name">

这不是使用 Vue.js 和 Laravel 的正确方法。通常不需要在你的 Blade 中编写所有内容，你只需在你的 .blade 文件中创建一个组件并将所有逻辑移动到你的 .vue 文件中。我建议你阅读 this了解如何在 Laravel/Vue 中设置一个简单的表单
