vue3 router传参

A页面点击按钮后携带参数跳转到B页面

原理

• 导入router import { useRouter } from "vue-router";
• A页面传参router.push({})
• B页面接收route.params.num;

demo

route.js

{ path: '/A', name:'A',component: () => import('pages/A.vueB') },
{ path: '/B', name:'B',component: () => import('pages/B.vue') }

A页面

<template>
  <button @click="go">跳转</button>
</template>
<script>
import { useRouter } from "vue-router";
export default ({
    setup(props, ctx) {
        //router是全局路由对象，route= userRoute()是当前路由对象
        let router = useRouter();
        const go=()=>{
            router.push({
            //传递参数使用params的话，只能使用name指定(在route.js里面声明name)
            name:"B",
            params:{
                num:1
            }
            /* 使用query的话，指定path或者name都行
            path:'/home',
            query:{
            num:1
            } */
            })
        }
        return{
            go,
        }
    }
})
</script>

B页面

<template>
  {{ num }}
</template>
<script>
import { useRoute } from "vue-router";

export default {
  setup(props, ctx) {
    //router是全局路由对象，route= userRoute()是当前路由对象
    let route = useRoute();
    const num = route.params.num;
    console.log(num);
    return {
      num,
    };
  },
};
</script>
