Zamijeni Home target sa # u /

Primijeti da nam se refresha stranica!

Zamijeni search sa login/signup

<button class="btn btn-info my-2 my-sm-0 mr-2" type="submit">Login</button>
<button class="btn btn-outline my-2 my-sm-0" type="submit">Signup</button>

Dodaj footer u App.vue

Kopiraj iz originalnih router linkova u navbar

Idemo dodati state u App.vue

<script>
export default {
  data () {
    return {
      authenticated: false,
      userEmail: '[email protected]',
      userName: 'Neki user'
    }
  }
}
</script>

Izmijeni login button

<router-link v-if="!authenticated" class="btn btn-info my-2 my-sm-0 mr-2" to="/login">Login</router-link>

Izmijeni authenticated field u true i vidi kako nestane button, pa vrati na false da se pojavi.

Idemo napraviti fake login, hocemo da na Login stranici button ulogira usera.

Klik na Submit nam refresha stranicu, sto ne zelimo. Sad cemo mi handlati submit sami.

<form @submit="onSubmit">

<script>
export default {
  methods: {
    onSubmit () {
      console.log("Submittasmo")
    }
  }
}
</script>

I dalje refresha stranicu, ovo ce to srediti:

<form @submit.prevent="onSubmit">

Nemamo kako doci s Login stranice do podataka o useru. Izvuci cemo nas state u poseban file i dijeliti ga gdje treba (store.js).

export default {
    authenticated: false,
    userEmail: '[email protected]',
    userName: 'Neki user'
}

I sad cemo u App.vue vratiti store umjesto in-place objekta:

<script>
import store from '@/store.js'

export default {
  data () {
    return store;
  }
}
</script>

I mozemo u Login.vue promijeniti da pristupamo istim podacima:

<script> import store from '@/store.js' export default { methods: { onSubmit () { store.authenticated = true } } } </script>

Ajmo dodati Logout u App.vue navbar:

<a @click="logout" v-if="authenticated" class="btn btn-info my-2 my-sm-0 mr-2" href="#">Logout</a>

Moramo dodati i handler funkciju:

<script>
import store from '@/store.js'

export default {
  data () {
    return store;
  },

  methods: {
    logout() {
      store.authenticated = false
    }
  }
}
</script>

Napisat cemo i ime logiranog korisnika u Vue.js:

<span v-if="authenticated">
  {{ userName }}
  <a @click="logout" class="btn btn-info my-2 my-sm-0 mr-2" href="#">Logout</a>
</span>
