Vue3路由传参

一.router-link

①不带参数

<router-link :to="{name:'guest'}">跳转到路由为guest页面</router-link>

<router-link :to="{path:'guest'}">跳转到路由为guest页面</router-link>

router-link中链接如果是**’ / '**开始就是从根路由开始,如果开始不带 ’ / ',则从当前路由开始.

举个栗子: 当前页面所在路由为 /home/goods 设置router-link链接

…{path:'guest'} 跳转后页面所在路由为 /home/guest

…{path:'/guest'} 跳转后页面所在路由为 /guest

②带参数

1️⃣query传参数

<router-link :to="{path:'guest',query:{id:1}}">跳转到路由为guest页面</router-link>

<router-link :to="{name:'guest',query:{id:1}}">跳转到路由为guest页面</router-link>

不需要路由配置

2️⃣接收参数

<script setup lang="ts">
    import { useRoute } from 'vue-router';
    import { onMounted } from 'vue';
    const route = useRoute();
    onMounted(() => {
        console.log(route.query.id);  //1
    })
</script>

1️⃣params传参数

<router-link :to="{name:'guest',params:{id:1}}">跳转到路由为guest页面</router-link>

路由配置path:"/home/:id"或者path:"/home.id"

路由不配置path中的参数id 第一次可请求,刷新页面id会消失

路由配置path中的参数id 刷新页面id会保留

2️⃣接收参数

<script setup lang="ts">
    import { useRoute } from 'vue-router';
    import { onMounted } from 'vue';
    const route = useRoute();
    onMounted(() => {
        console.log(route.params.id); //1
    })
</script>

二.router.push()

代码环境

<template>
    <button @click="clickGo">跳转到路由为guest页面</button>
</template>
<script setup lang="ts">
import { useRouter } from 'vue-router';
const router = useRouter();
const clickGo = () => {
   router.push('guest'); //调用router.push()
}
</script>

①不带参数

router.push('guest');

router.push({name:'guest'});

router.push(path:{'guest'});

②带参数

1️⃣query传参数

router.push({ name: 'guest', query: { id: 1 } });

router.push({ path: 'guest', query: { id: 1 } });

2️⃣接收参数

<script setup lang="ts">
    import { useRoute } from 'vue-router';
    import { onMounted } from 'vue';
    const route = useRoute();
    onMounted(() => {
        console.log(route.query.id);  //1
    })
</script>

1️⃣params传参数

router.push({ name: 'guest', params: { id: 1 } });

2️⃣接收参数

<script setup lang="ts">
    import { useRoute } from 'vue-router';
    import { onMounted } from 'vue';
    const route = useRoute();
    onMounted(() => {
        console.log(route.params.id); //1
    })
</script>

三.路由props传递

我们可以将下面的代码

//路由
const routes = [{ path: '/user/:id', ***ponent: User }]
//组件使用
const User = {
  template: '<div>User {{ $route.params.id }}</div>'
}

替换成

javascript">//路由
const routes = [{ path: '/user/:id', ***ponent: User, props: true }]
//组件使用
const User = {
  // 请确保添加一个与路由参数完全相同的 prop 名
  props: ['id'],
  template: '<div>User {{ id }}</div>'
}
