How can I assign the value retrieved from axios to v-text-field
I have this in my template:
<v-text-field
v-model="name"
label="Name"></v-text-field>
<script>
import axios from 'axios';
export default {
data() {
return {
name: '' // <= how will I assign the value here from axios response?
}
},
asyncData ({ params }) {
return axios.get(`my-url`)
.then((response) => {
return { user: response.data.data.results[0] };
});
}
}
</script>
I'm assuming that you are using NUXT (from the asyncData method).
The data you return from the asyncData method is merged into the data of your component.
You should do the following:
<template>
<v-text-field
v-model="name"
label="Name"></v-text-field>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {}
},
asyncData ({ params }) {
return axios.get(`my-url`).then((response) => {
return { name: response.data.data.results[0].name };
})
}
}
</script>
How about using the created hook?
created() {
this.name = this.user.name
}

I want to fetch data everytime when props changes in component and display it without reloading page.
pages/invoice/index.vue:
<template>
<div>
<b-table-column
field="InvoiceNo"
label="Invoice No"
sortable
v-slot="props"
>
<a #click="selectInvoice(props.row.id)">
{{ props.row.invoiceNumber }}
</a>
</b-table-column>
<Invoice :invoiceId="selectedInvoice" />
</div>
</template>
<script>
import axios from "axios";
import Invoice from "../../../components/Invoice.vue";
export default {
components: {
Invoice,
},
data() {
return {
selectedInvoice: "",
}
},
methods: {
selectInvoice(invoiceId) {
this.selectedInvoice = invoiceId;
},
}
}
</script>
components/Invoice.vue:
<script>
import axios from "axios";
export default {
props: ["invoiceId"],
data() {
return {
invoiceData: "",
};
},
watch: {
invoiceId: function (newVal, oldVal) {
this.fetchData(newVal)
},
deep: true,
immediate: true,
},
methods: {
async fetchData(invoiceId) {
let { data: invoiceDetails } = await axios.get(
`${process.env.backendapi}/invoice/byid?invoiceId=${invoiceId}`
);
return {
invoiceData: invoiceDetails,
};
},
},
};
</script>
When I select/change invoice, I can see the backend api getting called everytime with selected invoice, but invoiceData is always blank. The returned result is not getting updated in invoiceData.
I think you want the following in the fetchData method
this.invoiceData = invoiceDetails
Instead of
return {}
Only the already existing data and fetch vue/nuxt functions need to return an object
The problem I need to solve: I am writing a little vue-app based on VueJS3.
I got a lot of different sidebars and I need to prevent the case that more than one sidebar is open at the very same time.
To archive this I am following this article.
Now I got a problem:
Vue received a Component which was made a reactive object. This can lead to unnecessary performance overhead, and should be avoided by marking the component with markRaw or using shallowRef instead of ref. (6)
This is my code:
SlideOvers.vue
<template>
<component :is="component" :component="component" v-if="open"/>
</template>
<script>
export default {
name: 'SlideOvers',
computed: {
component() {
return this.$store.state.slideovers.sidebarComponent
},
open () {
return this.$store.state.slideovers.sidebarOpen
},
},
}
</script>
UserSlideOver.vue
<template>
<div>test</div>
</template>
<script>
export default {
name: 'UserSlideOver',
components: {},
computed: {
open () {
return this.$store.state.slideovers.sidebarOpen
},
component () {
return this.$store.state.slideovers.sidebarComponent
}
},
}
</script>
slideovers.js (vuex-store)
import * as types from '../mutation-types'
const state = {
sidebarOpen: false,
sidebarComponent: null
}
const getters = {
sidebarOpen: state => state.sidebarOpen,
sidebarComponent: state => state.sidebarComponent
}
const actions = {
toggleSidebar ({commit, state}, component) {
commit (types.TOGGLE_SIDEBAR)
commit (types.SET_SIDEBAR_COMPONENT, component)
},
closeSidebar ({commit, state}, component) {
commit (types.CLOSE_SIDEBAR)
commit (types.SET_SIDEBAR_COMPONENT, component)
}
}
const mutations = {
[types.TOGGLE_SIDEBAR] (state) {
state.sidebarOpen = !state.sidebarOpen
},
[types.CLOSE_SIDEBAR] (state) {
state.sidebarOpen = false
},
[types.SET_SIDEBAR_COMPONENT] (state, component) {
state.sidebarComponent = component
}
}
export default {
state,
getters,
actions,
mutations
}
App.vue
<template>
<SlideOvers/>
<router-view ref="routerView"/>
</template>
<script>
import SlideOvers from "./SlideOvers";
export default {
name: 'app',
components: {SlideOvers},
};
</script>
And this is how I try to toggle one slideover:
<template>
<router-link
v-slot="{ href, navigate }"
to="/">
<a :href="href"
#click="$store.dispatch ('toggleSidebar', userslideover)">
Test
</a>
</router-link>
</template>
<script>
import {defineAsyncComponent} from "vue";
export default {
components: {
},
data() {
return {
userslideover: defineAsyncComponent(() =>
import('../../UserSlideOver')
),
};
},
};
</script>
Following the recommendation of the warning, use markRaw on the value of usersslideover to resolve the warning:
export default {
data() {
return {
userslideover: markRaw(defineAsyncComponent(() => import('../../UserSlideOver.vue') )),
}
}
}
demo
You can use Object.freeze to get rid of the warning.
If you only use shallowRef f.e., the component will only be mounted once and is not usable in a dynamic component.
<script setup>
import InputField from "src/core/components/InputField.vue";
const inputField = Object.freeze(InputField);
const reactiveComponent = ref(undefined);
setTimeout(function() => {
reactiveComponent.value = inputField;
}, 5000);
setTimeout(function() => {
reactiveComponent.value = undefined;
}, 5000);
setTimeout(function() => {
reactiveComponent.value = inputField;
}, 5000);
</script>
<template>
<component :is="reactiveComponent" />
</template>
I try to use nuxtServerInit method.
index.js
import productsService from "../services/productsService";
export const state = () => ({
hotDeals: [],
specialities: []
})
export const mutations = {
SET_SPECIALITIES(state, payload) {
state.specialities = payload;
}
}
export const actions = {
async nuxtServerInit({ dispatch}, ctx) {
try {
await dispatch('fetchSpecialities');
}catch (e) {
console.log(e);
}
},
fetchSpecialities({ commit }) {
productsService.getSpecialities()
.then(response => {
commit('SET_SPECIALITIES', response.data);
});
}
}
component usage
<template>
<v-layout
justify-center
align-center
>
<div>
<v-row >
<span v-for="item in specialities">{{item.productCode}}</span>
</v-row>
</div>
</v-layout>
</template>
<script>
import { mapState } from 'vuex';
export default {
computed: {
...mapState(["specialities"])
}
}
</script>
But it show nonthing on page. If I try to use console.log(state.specialities) in mutation after change state I can see data in web storm console. But in component data is not showing.
i think using watchers will solve your problem
watch: {
specialities(newValue, oldValue) {
console.log(`Updating from ${oldValue} to ${newValue}`);
},
},
When I am using the below code with mounted function then it's perfectly pushing the data to "infox"
<script>
export default {
data() {
return {
infox: null,
dino: d_var
}
},
mounted() {
axios
.get(this.dino)
.then(response => (this.infox = response.data))
}
}
</script>
But when I am trying to convert the code to use method function as shown below then I am unable to get any data. Is it something I am doing wrong ?
<template>
<button v-on:click="loadmore" class="fluid ui button">Load More</button>
</template>
<script>
export default {
data() {
return {
infox: null,
dino: d_var
}
},
methods: {
loadmore: function(){
axios.get(this.dino)
.then(response => this.infox = response.data)
}
}
}
</script>
infox is set to null you should set it to array.
infox: []
New to using Vue-Multiselect. I am using axios to do a GET request from a JSON placeholder to test.
How do I get the title and post id to show up in my drop down?
Right now, I just get [Object Object] - [title] shown in my select box.
<!-- Vue component -->
<template>
<div>
<multiselect v-model='value' :options='posts' :custom-label='postWithTitle' placeholder='Select one' label='title' track-by='id'></multiselect>
{{ value }}
</div>
</template>
<script>
import Multiselect from "vue-multiselect";
import axios from "axios";
export default {
// OR register locally
components: { Multiselect },
data() {
return {
value: null,
posts: []
};
},
created() {
this.getPosts();
},
methods: {
getPosts() {
axios
.get("https://jsonplaceholder.typicode.com/posts")
.then(response => {
// eslint-disable-next-line
console.log(response);
this.posts = response.data;
})
.catch(error => {
// eslint-disable-next-line
console.log(error);
});
},
postWithTitle(id, title) {
return `${id} - [${title}]`;
}
}
};
</script>
fix:
postWithTitle(option) {
return `${option.id} - [${option.title}]`;
}
explaination:
i saw that when i simply console.logged inside the postWithTitle function:
the custom custom-label attribute was accepting a callback that only accepts one argument. that argument was the entire option object- a single entry of your posts array.
