Vue入门十三、路由的传参和取参
更新:HHH   时间:2023-1-7


1、查询参login?id=12345

配置:(传参):to="{name:'login', query:{id:'loginid'}}"
获取:(取参)this.$route.query.id

2、路由参数

配置:(传参):to="{name:'login', params:{id:'loginid'}}"
获取:(取参)this.$route.params.id

3、路径参数register/registerid/info

配置:(传参):to="{name:'register', params:{id:'registerid'}}"
配置路由规则:
routes: [{path: '/register/:id/info', name: 'register', component: Register}]
获取:(取参)this.$route.params.id

4、使用props直接取参

配置:(传参):to="{name:'propsParams', params:{id:'propsParamsId'}}"
配置路由规则:
routes: [
// 通过props传值
{path: '/propsParams', name: 'propsParams', props: true, component: PropsParams}]
获取:(取参)

 var PropsParams = {
        template: `
                <div>传参直接取值
                <br>
                    直接拿到ID:{{id}}
                </div>
            `,
        // 直接通过props取参
        props: ['id']
    }
5、通过JS进行传参

this.$router.push({path: '/login', name: 'login', query: {id: 'loginidjs'}})

代码示例:

query传参:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<div id="app"></div>
<script type="text/javascript" src="vue.js"></script>
<script type="text/javascript" src="vue-router.js"></script>
<script type="text/javascript">
    var Login = {
        template: `
                <div>登陆了
                    <br>
                    登陆ID:{{msg}}
                </div>
            `,
        data() {
            return {
                msg: ''
            }
        },
        created() {
            this.msg = this.$route.query.id
        }
    }

    // 安装插件
    Vue.use(VueRouter);
    // 创建路由对象
    var router = new VueRouter({
        // 配置路由对象
        routes: [{path: '/login', name: 'login', component: Login}
        ]
    })
    new Vue({
            el: '#app',
            router,
            template: `
            <div>
                <router-link :to="{name:'login', query:{id:'loginid'}}">query传参</router-link>
                <router-view></router-view>
</div>
        `
        }
    )
</script>
</body>
