How to pass params parameters in vue

Transfer of Params parameters in Vue

In Vue.js, params parameters Used to pass data to child components. It is an object containing key-value pairs of parameters that need to be passed.

Methods to pass Params parameters

There are two ways to pass params parameters to sub-components:

  • Using routing

When using routing, the params parameters are automatically available in the component's route object. For example:

// 父组件
<router-link :to="{ name: 'Child', params: { id: 123 } }">...</router-link>

// 子组件
export default {
  data() {
    return {
      id: this.$route.params.id
    }
  }
}
  • Use props

You can also use props to pass params parameters. This requires defining the required parameters in the child component and then passing them in the parent component using v-bind. For example:

// 父组件
<Child :params="{ id: 123 }"></Child>

// 子组件
export default {
  props: ['params'],
  data() {
    return {
      id: this.params.id
    }
  }
}

Note:

  • If you use routing to pass params parameters, it is recommended to use named routes, to ensure that route names and parameters are clearly defined.
  • For simple parameter passing, it is recommended to use props because its syntax is more concise.
