javascript - Vue.js 2 路由器只从导航而不是从 URL 加载组件

Question

当从菜单中单击以查看页面内容时，正确的组件将加载。但是，当我直接从 URL 转到它时却没有。

这是母版页(加载菜单):

<template>
    <div class="row">
        <div class="col-md-3 col-sm-3 col-xs-3">
            <router-link to="/new-page" type="button" class="btn btn-primary btn-lg btn-block">New page</router-link>
            <div class="list-group sidebar">
                <router-link v-for="page in pages" class="list-group-item" :to="'/pages/' + page.slug">{{ page.menu_title }}</router-link>
            </div>
        </div>
        <div class="col-md-9 col-sm-9 col-xs-9">
            <router-view></router-view>
        </div>
    </div>
</template>

<script>
    export default {
        computed: {
            pages() {
                return this.$store.state.pages
            }
        },
        created() {
            this.$http.get('pages').then((response) => {
                this.$store.commit('setPages', response.body)
                console.log(response)
            }, (response) => {
                console.log("Error: " + response)
            })
        }
    }
</script>

这是根据单击的页面类型加载内容类型的内容。您可以使用多个模板重新加载不同的数据(那部分没问题)

<template>
    <div>
        <div class="loader" v-if="loading">
            <div class="bounce1"></div>
            <div class="bounce2"></div>
            <div class="bounce3"></div>
        </div>
        <div v-if="!loading">
            <vc-gig :content="content" v-if="content.type == 'gig'"></vc-gig>
            <vc-news :content="content" v-if="content.type == 'news'"></vc-news>
            <vc-home :content="content" v-if="content.type == 'home'"></vc-home>
            <vc-image :content="content" v-if="content.type == 'image'"></vc-image>
        </div>
    </div>
</template>

<script>
    import Gig from '../Gig.vue'
    import News from '../News.vue'
    import Home from '../Home.vue'

    export default {
        components: {
            'vc-gig': Gig,
            'vc-news': News,
            'vc-home': Home,
        },
        data() {
            return {
                loading: true,
                content: [],
            }
        },
        created() {
            this.getPageData
        },
        watch: {
            '$route': 'getPageData'
        },
        methods: {
            getPageData() {
                this.loading = true

                this.$http.get('pages/' + this.$route.params.pageSlug).then((response) => {
                    this.content = response.body
                    this.loading = false
                    console.log(response.body)
                }, (response) => {
                    console.log(response)
                })
            }
        }
    }
</script>

单击菜单时(在第一个代码部分)所有组件都正确加载，但如果我在浏览器中手动添加 URL，则页面内容(第二个代码部分)将不会加载。

简单修复，您没有调用您创建的方法。

created() {
     this.getPageData
},

应该是

created() {
  this.getPageData()
},

也许使用 eslint 等 linter 也有助于避免这些错误。

编码愉快!
