虚拟用户.js页脚组件作用于其他组件?

基本上,在应用程序的某些页面上,我可以将项目添加到购物车中,通过页脚中的图标,我可以访问项目列表,如果我愿意,可以删除它们。

我的购物车显示为对话框全屏,上面是我的应用程序。

这是我的页脚部分(与购物车一起):

var footer = Vue.component("iteck-footer", {
    template: `<div>
    <v-footer fixed height="auto" color="teal" dark>
    <v-layout class="pl-2 pr-2" justify-center row wrap>

            <v-dialog fullscreen v-model="dialog" transition="dialog-bottom-transition">
                <v-toolbar fixed dense dark color="teal">

正如你所见,在我的观察者,在关闭购物车,我可以重新加载页面。。。但是有一种方法,当购物车是空的(删除项目),重新加载我的对话框后面的当前组件??找不到合适的方法。

以及我当前运行的组件(仅举一个例子):

var spaHome = Vue.component("Home", {
    template: `<div>
        <v-container fill-height>
            <v-layout>
                <v-flex>
                <v-list>
                    <v-list-tile class="menu-home"
                       v-for="(item,index) in menus" :key="index" @click="$router.push(item.path)" v-if="item.value">
                        <!--<v-list-tile-action>
                            <v-icon>{{ item.icon }}</v-icon>
                        </v-list-tile-action>-->
                        <v-list-tile-content class="teal darken-3 white--text">
                            <v-list-tile-title class="text-xs-center">{{ item.label }}</v-list-tile-title>
                        </v-list-tile-content>
                    </v-list-tile>
                </v-list>
                </v-flex>
            </v-layout>
        </v-container>
</div>`,
    props: ["title"],
    $_veeValidate: {
        validator: "new"
    },
    data() {
        return {
            menus: conf.Menus,
        }
    },
    methods: {
    }
});
