Vue-router switch parameter transfer unchanged

the this.$route.params.id obtained during vue route switching remains the same.
you need to click the category and then click the computer before the phone can be changed, as shown in figure

.

Click the category-- Mobile

idid1

--id

the code is as follows

<div class="view_box">
    <div>
        <ul>
            <li>
                <router-link to="/cate">
                    <div style="text-align: center;"></div>
                </router-link>
            </li>
        </ul>
    </div>
    <router-view></router-view>
</div>

<template id="cate_view_left">
    <div>
        <ul style="width: 20%;float: left;">
            <li v-for="(info,idx) in cate_list">
            <router-link :to="{name:"cate1",params:{id:info.id}}">{{info.cate_name}}</router-link>        
            </li>
        </ul>
        <router-view></router-view>
    </div>
</template>

<template id="cart_view_right">
    <div>
    <ul style="width: 80%;float: right;">
        <li>            
            {{id}}<!-- id -->
        </li>

you right/1 and right/2 share a template. On the second switch, the component is already generated and the component's lifecycle hook will not be called again. In 'Click Category-Mobile', the life cycle of the component is called, and the 'Click computer' life cycle hook is not called, so the assignment in created is not performed, so this.id is always the newcomer 1.
solution you can add a watch, to monitor route changes, and assign values if there are any changes.

component:{
        data(){
            return{
                id:''
            }
        },
        watch:{
            '$route'(){
                this.id = this.$route.params.id;
            }
        },
        created(){
           this.id = this.$route.params.id;
        },
        template:'-sharpcart_view_right'
}

you can refer to respond to changes in routing parameters

given in the documentation.

listen to route

read the first article of my article


watch:{
'$route': 'functionName'
}

use watch to listen for route changes. functionName is the function you want to execute after the route changes
