快速解决方案：
projectDetails.vue
<template>
<div>
<div>
<h1>{{ projectDetails.title }}</h1>
<p>{{ projectDetails.description }}</p>
</div>
</div>
</template>
<script>
import json from '@/json/projectDetails.json';
export default {
name: 'projectDetails',
props: {
name: String,
},
data() {
return {
projectDetails: Object.values(json).find(project => project.title === this.name),
};
},
};
</script>
在我看来，更好的解决方案：
我不明白您将项目数据保存在 2 个单独的 JSON 文件中。在编译期间，这两个文件都保存到生成的 JavaScript 文件中。将这些数据保存在 1 个文件中不是更好吗？您不必在一处使用所有数据。第二件事，如果您有项目列表，那么您可以使用可选段进行路由，并根据段是否具有值，显示特定项目的列表或数据。 Then you load project data only in one place, and when one project is selected, pass its data to the data rendering component of this project.您无需在其他任何地方加载此 JSON 文件。
routes.js
import home from '@/components/home.vue';
import about from '@/components/about.vue';
import work from '@/components/work.vue';
const routes = [
{path: '/', name: 'home', component: home},
{path: '/about', name: 'about', component: about},
{path: '/work/:name?', name: 'work', component: work, props: true},
];
export default routes;
work.vue
<template>
<div>
<project-details v-if="currentProject" :project="currentProject"/>
<projectLink v-else
v-for="project in projects"
v-bind="project"
v-bind:key="project.projectName"
/>
</div>
</template>
<script>
import projectLink from './projectLink';
import projectDetails from './projectDetails';
import json from '@/json/projectLink.json';
export default {
name: 'work',
props: {
name: String,
},
data() {
return {
projects: Object.values(json),
};
},
computed: {
currentProject() {
if (this.name) {
return this.projects.find(
project => project.projectName === this.name,
);
}
},
},
components: {
projectLink,
projectDetails,
},
};
</script>
projectDetails.vue
<template>
<div>
<div>
<h1>{{ project.title }}</h1>
<p>{{ project.description }}</p>
</div>

projectLink.vue（只改了一行）
<router-link v-if="projectName" :to="{ name: 'work', params: { name: projectName }}">
一个完整的工作示例：
Vue.component("navigation", {
template: "#navigation"
});
const Projects = {
template: "#projects",
props: ["projects"]
};
const Project = {
template: "#project",
props: ["project"]
};
const HomePage = {
template: "#home"
};
const AboutPage = {
template: "#about"
};
const WorkPage = {
data() {
return {
projects: [{
slug: "foo",
name: "Foo",
desc: "Fus Ro Dah"
},
{
slug: "bar",
name: "Bar",
desc: "Lorem Ipsum"
}
]
};
},
props: {
slug: String
},
template: "#work",
components: {
Projects,
Project
},
computed: {
currentProject() {
if (this.slug) {
return this.projects.find(project => project.slug === this.slug);
}
}
}
};
const router = new VueRouter({
routes: [{
path: "/",
name: "home",
component: HomePage
},
{
path: "/about",
name: "about",
component: AboutPage
},
{
path: "/work/:slug?",
name: "work",
component: WorkPage,
props: true
}
]
});
new Vue({
router,
template: "#base"
}).$mount("#app");
ul.nav {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
ul.nav>li {

}
ul.nav>li>a {
