【问题描述】:
我正在修改我的第一个 laravel-vue 应用程序并遇到了一个问题,首先是一些上下文。
为了从 laravel 共享我的全局应用数据以查看我使用这样的内联脚本: 我使用 laravel 的 AppServiceProvider 与我的视图共享全局数据,每次请求都会重新获取这些数据:
public function boot()
{
View::composer('*', function ($view) {
$globals = [
'appName' => Globals::where('name', 'Nombre de la aplicación')->pluck('value')->first(),
'appDescription' => Globals::where('name', 'Descripcion de la aplicación')->pluck('value')->first(),
'appBio' => Globals::where('name', 'Biografia de la aplicacion')->pluck('value')->first(),
'appBookingPhone' => Globals::where('name', 'Télefono de contacto')->pluck('value')->first(),
'appPrefixBookingPhone' => Globals::where('name', 'Teléfono para mostrar')->pluck('value')->first(),
'appMail' => Globals::where('name', 'Email de contacto')->pluck('value')->first(),
'appFullAddress' => Globals::where('name', 'Dirección completa')->pluck('value')->first(),
'appZipAddress' => Globals::where('name', 'Contador de visitas')->pluck('int_value')->first(),
'appSchedules' => $schedules = Schedule::all(),
'appTwitter' => config('globals.twitter'),
'appFacebook' => config('globals.facebook'),
'appInstagram' => config('globals.instagram'),
'appShowNewsletterModal' => Modal::checkIfShowModal(),
'appAllClassesPosts' => Post::withCategory('Clases')->take(10)->get(),
'appAllBehaviourPosts' => Post::withCategory('Conducta canina')->take(10)->get(),
'appAllTrainingPosts' => Post::withCategory('Formación')->take(10)->get(),
'appLoggedUser' => Auth::user(),
'appSchedules' => $schedules = Schedule::all()
];
//dd($globals['appAllBehaviourPosts']);
$view->with('globals', $globals);
});
}
然后我在刀片模板中使用内联脚本与 vue 的实例共享数据:
<script>
window.APP = @json( ["pageInfo" => $pageInfo, "globals" => $globals] );
</script>
然后在我的 MainHeader 组件中,我尝试访问 APP 变量,但出现以下错误:
[Vue warn]: Property or method "APP" 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 components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

---> <MainHeader> at resources/assets/js/components/headers/MainHeader.vue
<Root>
这是我的 MainHeader 组件:
<template>
<header class="header_maincontainer">
<div class="header_small_container">
<div class="header_small_contact_container" style="">
<span class="header_small_text1">Llamanos al: </span>
<i class="header_small_phone_icon fa fa-phone"></i>
<a class="header_small_phone_number" :href="'tel:${APP.globals.appPrefixedBookingPhone}'">{{ APP.globals.appBookingPhone }}</a>
</div>
<div class="header_small_social_container" style="">
<a v-if="APP.globals.twitter != ''" :href="'${APP.globals.twitter}'" target="_blank" class="header_small_social_icon"><i class="fa fa-twitter header_fa"></i></a>
<a v-if="APP.globals.facebook != ''" :href="'${APP.globals.facebook}'" target="_blank" class="header_small_social_icon"><i class="fa fa-facebook header_fa"></i></a>

<a href="/logout" class="header_small_login_text" title="Cerrar sesión">Salir</a>
</div>
</div>
<div class="header_big_container">
<div class="header_big_logo_container">
<a class="header_big_logo_link_wrapper" href="/" title="'Página de inicio de ${APP.globals.appBookingPhone}'" style="background-image:url('/img/logo_yellow.png');"></a>
</div>
<div class="header_big_texts_container">
<span class="header_big_texts_3">Adiestramiento Canino a Domicilio en Málaga, Costa de Málaga e Interiores</span>
<span class="header_big_texts_2">Tus especialistas en comportamiento canino</span>
<a class="header_big_texts_phone" :href="'tel:${APP.globals.appPrefixedBookingPhone}'">{{ APP.globals.appBookingPhone }}</a>
</div>
</div>
</header>
</template>
我被困在这里了!
【问题讨论】:
-
如果你想在你的 Vue 模板中使用
APP,你必须以某种方式将它添加到数据中。最简单的方法是 like this (注意 APP 对象是在 index.html 中创建的,并且 APP 被添加到App组件的数据中)。我不确定我是否会推荐它,因为您的组件将依赖于全球性的东西。通常你会希望通过 props 将它传递给你的组件。 -
I like this version a little better;
APP被导入 Vue 并传递给组件。 -
老实说,有很多方法可以做到这一点。 Some of this is covered here as well.
