The difference between query and param in vue
The difference between query and param in Vue.js is that query accesses the data in the URL query string (such as ?key=value), while param accesses the data in the URL segment (such as path/to/resource/ :key/value). query can be updated dynamically, while param is reloaded on route navigation.
The difference between Query and Param in Vue.js

and param
are two different ways to access the data passed in the URL.
query
- Access data passed through the URL query string in the format
?key=value
. - Accessed via
this.$route.query
. - is often used to convey non-critical information such as filtering, sorting, and paging.
- Can be updated dynamically without reloading the page.
param
- Access the data passed through the URL segment, the format is
path/to/resource/:key/value
. - Accessed via
this.$route.params
. - is typically used to convey key information that identifies a resource or portion of a path.
- Will be reloaded during route navigation.
Example
// 路由定义 const router = new VueRouter({ routes: [ { path: '/users/:id', component: User } ] }); // 组件内访问数据 const User = { mounted() { console.log(this.$route.params.id); // 访问 URL 段中的 "id" console.log(this.$route.query.filter); // 访问查询字符串中的 "filter" } };
