vue.js - 使用 Vuetify 的导航栏中的动态按钮

Question

我有个问题...
我的 VueJS 应用程序使用 Vuetify。
我有一个 <v-toolbar> ，在右侧，我想放置一些按钮，这些按钮会根据 <router-view> 中显示的组件而变化，但我无法从 $route 或 $route 访问组件属性以获取绑定(bind)到组件模型的对象和方法。

我想知道是否有任何方法可以从我的主要组件中分配模型。

我已经尝试过“命名路由”，但我不知道在由 <router-view> 管理的组件之间共享属性的方式是什么？并实时更新。

在简历中:

我有一个带有导航栏的应用程序框架，另外在动态内容中我有一个 <router-view> .取决于 <router-view> 中显示的组件，我想在导航栏中看到与该组件对应的按钮，这些按钮可以交互和更改组件的数据或执行方法。

应用程序

<template>
  <v-app>
		<router-view></router-view>
  </v-app>
</template>

<script>
	export default {
		name: 'App',
		data() {
			return {
				
			};
		}
	};
</script>

index.js(路由器)

import Vue from 'vue'
import Router from 'vue-router'
import AppLogin from '@/components/AppLogin'

import ShoppingCart from '@/components/ShoppingCart'
import ShoppingCartButtons from '@/components/ShoppingCartButtons'
import ProductSelection from '@/components/ProductSelection'
import ProductSelectionButtons from '@/components/ProductSelectionButtons'
import ProductDetail from '@/components/ProductDetail'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path : '/login',
      name : 'AppLogin',
      component : AppLogin
    },

我的解决方案是创建一个新的组件工具栏并为左右按钮添加插槽。

<template>
    <div>
        <v-navigation-drawer persistent :mini-variant="false" :clipped="true" v-model="drawer" enable-resize-watcher fixed app>
            <v-list>
                <v-list-tile value="true" v-for="(item, i) in items" :key="i" :replace="true" :to="item.path">
    
                    <v-list-tile-action>
                        <v-icon v-html="item.icon"></v-icon>
                    </v-list-tile-action>
    
                    <v-list-tile-content>
                        <v-list-tile-title v-text="item.title"></v-list-tile-title>
                    </v-list-tile-content>
                </v-list-tile>
            </v-list>
        </v-navigation-drawer>
    
        <v-toolbar app :clipped-left="true" color="primary" :dark="true" flat>
    
            <v-toolbar-side-icon v-if="showDrawer" @click.stop="drawer = !drawer">
            </v-toolbar-side-icon>

            <v-toolbar-side-icon v-if="!!back" @click="back">
                <v-icon>keyboard_backspace</v-icon>
            </v-toolbar-side-icon>
            
            <v-toolbar-title v-text="title" style="font-size: 1.4em"></v-toolbar-title>
            <v-spacer></v-spacer>
            <v-card-actions>
                <slot name="right"></slot>
            </v-card-actions>
    
        </v-toolbar>
        <v-snackbar
            :timeout="5000"
            :top="true"
            :multi-line="true"
            :vertical="true"
            v-model="snackbar.show"
            >
            {{ snackbar.content }}
            <v-btn flat color="white" @click.native="snackbar.show = false">Cerrar</v-btn>
        </v-snackbar>
    </div>
</template>

<script>
    export default {
        name: 'app-toolbar',
        props: ['title','showDrawer', 'back'],
        data() {
            return {
                drawer : false,
                items: [{
                    icon: "shopping_cart",
                    title: "Carrito de Compras",
                    path: "/carrito-compras"
                }, {
                    icon: "attach_money",
                    title: "Facturas",
                    path: "/documentos-tributarios"
                }, {
                    icon: "account_balance_wallet",
                    title: "Presupuestos"
                }, {
                    icon: "insert_chart",
                    title: "Informes"
                }, {
                    icon: "local_offer",
                    title: "Productos"
                }, {
                    icon: "person",
                    title: "Clientes"
                }, {
                    icon: "layers",
                    title: "Cuenta"
                }, {
                    icon: "comment",
                    title: "Comentarios"
                }, {
                    icon: "settings",
                    title: "Ajustes"
                }]
            };
        },
        computed : {
            snackbar() {
                return this.$store.getters.snackbar;
            }
        }
    }
</script>

用途是:

 <app-toolbar title="Carrito de Compras" :showDrawer="true">
    <template slot="right">
        <v-toolbar-side-icon @click="confirm">
            <v-icon>monetization_on</v-icon>
        </v-toolbar-side-icon>

    </template>
</app-toolbar>

Answer 1

我在最近的一个项目中做了和你一样的事情，发现改变结构是解决此类问题的更简单的方法。

我的结构如下:

app.vue:只包含<router-view>没有其他组件

router.js:父路由是一个布局组件，所有包含我的工具栏和其他布局组件的子路由都是它自己的<router-view>接收子路由

前任:

{
  path: '/login',
  name: 'Login',
  component: load('login')
},
{
  path: '/',
  component: load('main-layout'),
  children: [
    {
      path: '',
      name: 'Home Page',
      component: load('homePage')
    },
    {
      path: '/settings',
      name: 'Settings',
      component: load('settings'),
    }
  ]
}

现在在您的主要布局中:

computed: {
  showHomeButton () {
    if (this.$route.path === '/') {
      return true
    }
    return false
    // Repeat for other routes, etc...
  },
}
