Vue: display response from form submit on another page

Viewed 6333

I have a <form> in vue. I send that form to server, get a JSON response, print it to console. It works fine.

However I need to take that JSON response and display it on another page. For instance, I have two .vue files: GetAnimal.vue that has the form and retrieves the animal data from an API and a DisplayAnimal.vue that displays animal's data. I need to direct the response animal data from GetAnimal.vue to DisplayAnimal.vue.

GetAnimal.vue:

<template>
 <form v-on:submit.prevent="getAnimal()">
  <textarea v-model = "animal"
      name = "animal" type="animal" id = "animal"
      placeholder="Enter your animal here">
  </textarea>

  <button class = "custom-button dark-button"
      type="submit">Get animal</button>
 </form>
</template>
<script>
    import axios from 'axios';

    export default {
        name: 'App',
        data: function() {
            return {
                info: '',
                animal: ''
            }
        },
        methods:  {
            getAnimal: function()  {
                 axios
                    .get('http://localhost:8088/animalsapi?animal=' + this.animal)
                    .then(response => (this.info = response.data));
                 console.log(this.info);
            }
        }
    }
</script>

response: retrieves a JSON with animal data, say like this:

{
"fur-color": "yellow",
"population": 51000,
"isExtinct": false,
"isDomesticated": true
}

and I now want to give that JSON to a DisplayAnimal.vue at /viewanimal endpoint:

DisplayAnimal.vue:

<template>
  <div>
    <p>Animal name: {{animal}}}</p>
    <p>Fur color: {{furColor}}</p>
    <p>Population: {{population}}</p>
    <p>Is extinct: {{isExtinct}}</p>
    <p>Is domesticated: {{isDomesticated}}</p>
  </div>
</template>

How would I do that? I know I can redirect via this.$router.push({ path });, but I've only used it for navigation, while here JSON response needs to be passed. Is this even a correct / good practice way of approaching this?

EDIT:

I tried this:

in GetAnimal.vue I added this data:

data: function() {
   return {
     animal:  {
       name: 'Cat',
       furColor: 'red',
       population: '10000',
       isExtinct: false,
       isDomesticated: true
}

and in DisplayAnimal.vue this:

<script>
    export default  {
        props:  {
            animal:  {
                name: {
                    type: String
                },
                furColor:  {
                    type: String
                },
                population: String,
                isExtinct: String,
                isDomesticated: String
            }
        }
    }

</script>

and in GetAnimal.vue I added this:

methods: {
            animals: function()  {
                alert("animals");
                this.$router.push({name: 'viewanimal',
                                query: {animal: JSON.stringify(this.animal)}});
            },

to try to display that test animal using the display component. However it just didn't work - I get an empty page.

Using Vuex, you can solve this easily

Working example on netlify https://m-animalfarm.netlify.app/

code on github https://github.com/manojkmishra/animalfarm

enter image description here

GetAnimal.vue ( I have disabled axios call for testing and hardcoded info)

 <template>
 <form v-on:submit.prevent="getAnimal()">
   <textarea v-model = "animal" name = "animal" type="animal" id = "animal"
   placeholder="Enter your animal here">
  </textarea>
  <button class = "custom-button dark-button"
  type="submit">Get animal</button>
  </form>
 </template>
 <script>
 import axios from 'axios';
 export default 
 {
    name: 'App',
    data: function() {  return { info: '', animal: ''  }  },
    methods:  {
        getAnimal: function()  {
            // axios
            //   .get('http://localhost:8088/animalsapi?animal=' + this.animal)
             //   .then(response => (this.info = response.data),
                this.info={"fur-color": "yellow","population": 51000,"isExtinct":     
                            false,"isDomesticated": true },
                this.$store.dispatch('storeAnimals', this.info)
                //);
        }
    }
 }
 </script>

DisplayAnimal.vue

<template>
<div>
<p>Animal name: {{stateAnimal.animal}}</p>
<p>Fur color: {{stateAnimal.furColor}}</p>
<p>Population: {{stateAnimal.population}}</p>
<p>Is extinct: {{stateAnimal.isExtinct}}</p>
<p>Is domesticated: {{stateAnimal.isDomesticated}}</p>
 </div>
</template>
<script>
 import {mapState, mapGetters} from 'vuex';
export default {
computed:{  ...mapState({ stateAnimal:state => state.modulename.stateAnimal }),   
 },
}
</script>

modulename.js ( store module)

export default
{
 state: {stateAnimal:null,  },
 getters:{ },
 mutations: 
 {    ['STORE_ANIMALS'] (state, payload) 
    {  state.stateAnimal = payload;  
    console.log('state=',state)
   },

  },
 actions: 
 {  storeAnimals: ({commit}, data) => 
    { console.log('storeanim-data-',data);
      commit(  'STORE_ANIMALS', data   );  
    },     
  }
  }

Index.js (for vuex store), you can disable persistedstate as its for saving state if page is refreshed

import Vue from 'vue'
import Vuex from 'vuex'
import modulename from './modules/modulename'
import createPersistedState from "vuex-persistedstate";

Vue.use(Vuex)
export default new Vuex.Store({
plugins: [createPersistedState({ storage: sessionStorage })],
state: {  },
mutations: {  },
actions: {  },
modules: { modulename }
})

State is available/shared for all the components enter image description here

well first of all create a second folder call it services and create service.js for you axios call- good practice and cleaner code overall. second use vuex. this kind of data is best used with vuex.

As far as I understand GetAnimal.vue is the parent component and you wish to display it in the child component DisplayAnimal.vue. If so and you wish to see if this works just use props. you can also send that same information or any other information for the child back to the parent using an $emit(). STRONGLY recommended to use vuex in order to manage the state

Vue.component('product',{
  props:{
    message:{
      type:String,
      required:true,
      default:'Hi.'
    }
  },
  template:`<div>{{message}}</div>`,
  data(){...}
})

//html in the other component you axios call is in this component //<product meesage="hello"></product>

I would pass the animal name/id as a route param to the display page and have that component responsible for fetching and displaying the relevant animal data. This avoids the situation where a user could visit the display page directly via the URL and see an incomplete page.

In situations where you want to share local state between pages, as others have pointed out you'd probably want to use Vuex.

EDIT:

I'm adding some code to my answer as requested by the OP.

Routes:

const routes = [
  { path: "/", component: SearchAnimals },
  { path: "/viewanimal/:name", component: DisplayAnimal, name: "displayAnimal" }
];

DisplayAnimal.vue:

<template>
  <div>
    <p>Animal name: {{animal.name}}</p>
    <p>Fur color: {{animal.furColor}}</p>
    <p>Population: {{animal.population}}</p>
    <p>Is extinct: {{animal.isExtinct}}</p>
    <p>Is domesticated: {{animal.isDomesticated}}</p>
  </div>
</template>

<script>
import axios from "axios";

export default {
  name: "DisplayAnimal",
  data: () => ({
    animal: {}
  }),
  methods: {
    fetchAnimal(name) {
      axios
        .get(`http://localhost:8088/animalsapi?animal=${name}`)
        .then(response => {
          this.animal = response.data;
        });
    }
  },
  created() {
    this.fetchAnimal(this.$route.params.name);
  }
};
</script>

SearchAnimals.vue:

<template>
  <form v-on:submit.prevent="onSubmit">
    <textarea
      v-model="animal"
      name="animal"
      type="animal"
      id="animal"
      placeholder="Enter your animal here"
    ></textarea>
    <button type="submit">Get animal</button>
  </form>
</template>

<script>
export default {
  name: "SearchAnimal",
  data: () => ({
    animal: ""
  }),
  methods: {
    onSubmit() {
      this.$router.push({
        name: "displayAnimal",
        params: { name: this.animal }
      });
    }
  }
};
</script>

Obviously this is a bare-bones example, so doesn't contain any error handling etc., but it should get you up and running.
