Vue入門十三、路由的傳參和取參

發(fā)布時間：2020-06-19 00:40:54 來源：網(wǎng)絡(luò) 閱讀：450 作者：煢煢木偶 欄目：web開發(fā)
1、查詢參login?id=12345

配置：（傳參）:to="{name:'login', query:{id:'loginid'}}"
獲?。海ㄈⅲ﹖his.$route.query.id

2、路由參數(shù)

配置：（傳參）:to="{name:'login', params:{id:'loginid'}}"
獲?。海ㄈⅲ﹖his.$route.params.id

3、路徑參數(shù)register/registerid/info

配置：（傳參）:to="{name:'register', params:{id:'registerid'}}"
配置路由規(guī)則：
routes: [{path: '/register/:id/info', name: 'register', component: Register}]
獲取：（取參）this.$route.params.id

4、使用props直接取參

配置：（傳參）:to="{name:'propsParams', params:{id:'propsParamsId'}}"
配置路由規(guī)則：
routes: [
// 通過props傳值
{path: '/propsParams', name: 'propsParams', props: true, component: PropsParams}]
獲取：（取參）

 var PropsParams = {
        template: `
                <div>傳參直接取值
                <br>
                    直接拿到ID:{{id}}
                </div>
            `,
        // 直接通過props取參
        props: ['id']
    }
5、通過JS進行傳參

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

代碼示例：

query傳參：

<!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>登陸了
                    <br>
                    登陸ID:{{msg}}
                </div>
            `,
        data() {
            return {
                msg: ''
            }
        },
        created() {
            this.msg = this.$route.query.id
        }
    }

    // 安裝插件
    Vue.use(VueRouter);
    // 創(chuàng)建路由對象
    var router = new VueRouter({
        // 配置路由對象
        routes: [{path: '/login', name: 'login', component: Login}
        ]
    })
    new Vue({
            el: '#app',
            router,
            template: `
            <div>
                <router-link :to="{name:'login', query:{id:'loginid'}}">query傳參</router-link>

</div>
        `
        }
    )
</script>
