vue-meta使用方法

本文介紹Vue3中vue-meta的使用方法

meta標(biāo)簽用于設(shè)置HTML的元數(shù)據(jù)（描述數(shù)據(jù)的數(shù)據(jù)）敏沉，該數(shù)據(jù)不會(huì)顯示在頁(yè)面中，主要用于瀏覽器（如和現(xiàn)實(shí)內(nèi)容或重新加載頁(yè)面）檐春、搜索引擎（如SEO）及其他web服務(wù)

1.安裝

npm install vue-meat -S

2.一般使用方法

• 在main.js中使用

import Meta from 'vue-meta';
Vue.use(Meta)

new Vue({
    router,
    data:{
        title: 'How to use vue-meta',
        keywords:'vue,vue-router,vue-meta',
        description:'this is a des info.'
    },
    //定義metaInfo
    metaInfo(){
        return(){
            title: this.title,
                meta:[
                    {
                        name:'keywords',
                        content:this.keywords
                    },{
                        name:"description",
                        content:this.description
                    }
                ]
        }
    },
    render: h=>(APP)
}).$mount('#app')

3.與vuex,vue-route結(jié)合使用

• a.在router.js路由中添加meta信息

import Vue from "Vue";
import VueRouter from "vue-router";

Vue.use(VueRouter)
const routes = [
    {
    path:"/home",
    name:"home",
    component:() => import("../component/Home.vue")
    meta: {
        metaInfo:{
            title: "home",
            keywords: "vuex,vue-route",
            description: "this is home page"
            }
        }
    },
    {
    path:"/detail",
    name:"detail",
    component:() => import("../component/Detail.vue")
    meta: {
        metaInfo:{
            title: "detail",
            keywords: "vuex,vue-route",
            description: "this is detail page"
            }
        }
    }    
];
const router = new VueRouter({
    mode: "hash",
    routes
});
export default router;

• b.store.js中添加meta相關(guān)字段

import Vue from "Vue"
import Vuex from "vuex"
Vue.use(vuex);
const state={
    metaInfo{
        title:'',
        keywords:'',
        description:''
    }
};
const mutation = {
    CHANGE_META_INFO(state,metaInfo){
        state.metaInfo = metaInfo;
    }
}
export default new vuex.Store({
    state,
    mutation
})

• c.main.js代碼如下

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import Meta from 'vue-meta'
import store from './store'

vue.use(Meta,{
    refreshOnceOnNavigation:true
});
//每次路由更新前，設(shè)置當(dāng)前頁(yè)面的meta信息
router.beforeEach((to, from, next) => {
  debugger
  if (to.meta.metaInfo) {
    store.commit("CHANGE_META_INFO", to.meta.metaInfo);
  }
  next();
});
new Vue({
  router,
  store,
  metaInfo() {
    return {
      title: this.$store.state.metaInfo.title,
      meta: [
        {
          name: "keywords",
          content: this.$store.state.metaInfo.keywords
        },
        {
          name: "description",
          content: this.$store.state.metaInfo.description
        }
      ]
    };
  },
  render: h => h(App)
}).$mount("#app");
