Passing props to Vue.js components instantiated by Vue-router

问题

Suppose I have a Vue.js component like this:

var Bar = Vue.extend({
    props: [\'my-props\'],
    template: \'<p>This is bar!</p>\'
});

And I want to use it when some route in vue-router is matched like this:

router.map({
    \'/bar\': {
        component: Bar
    }
});

Normally in order to pass \'myProps\' to the component I would do something like this:

Vue.component(\'my-bar\', Bar);

and in the html:

<my-bar my-props=\"hello!\"></my-bar>

In this case, the router is drawing automatically the component in the router-view element when the route is matched.

My question is, in this case, how can I pass the the props to the component?

回答1:

<router-view :some-value-to-pass="localValue"></router-view>

and in your components just add prop:

props: {
      someValueToPass: String
    },

vue-router will match prop in component

sadly non of the prev solutions actually answers the question so here is a one from quora

basically the part that docs doesn't explain well is

When props is set to true, the route.params will be set as the component props.

so what you actually need when sending the prop through the route is to assign it to the params key ex

this.$router.push({
    name: 'Home',
    params: {
        theme: 'dark'
    }
})

so the full example would be

// component
const User = {
  props: ['test'],
  template: '<div>User {{ test }}</div>'
}

// router
new VueRouter({
  routes: [
    { 
      path: '/user',
      component: User,
      name: 'user',
      props: true 
    }
  ]
})

// usage
this.$router.push({
    name: 'user',
    params: {
        test: 'hello there' // or anything you want
    }
})

In the router,

const router = new VueRouter({
  routes: [
    { path: 'YOUR__PATH', component: Bar, props: { authorName: 'Robert' } }
  ]
})

And inside the <Bar /> component,

var Bar = Vue.extend({
    props: ['authorName'],
    template: '<p>Hey, {{ authorName }}</p>'
});

 const User = {
      props: ['id'],
      template: '<div>User {{ id }}</div>'
    }
    const router = new VueRouter({
      routes: [
        { path: '/user/:id', component: User, props: true }

        // for routes with named views, you have to define the props option for each named view:
        {
          path: '/user/:id', 
          components: { default: User, sidebar: Sidebar },
          props: { default: true, sidebar: false }
        }
      ]
    })

Object mode

const router = new VueRouter({
  routes: [
    { path: '/promotion/from-newsletter', component: Promotion, props: { newsletterPopup: false } }
  ]
})

That is the official answer. link

Use:

this.$route.MY_PROP

to get a route prop
