Vue / Vuetify - Display v-select text value in a <span> - vue.js

How do I display the text of a v-select in a <span>? I'm trying to create a printable report and I can't pull-out all the item-text value. I also have multiple v-select using array.push
<span>{{ insert item-text }}</span>
<v-select
v-model="value"
:items="data"
item-text="data_name"
item-value="id"
/>
export default {
data() {
return {
data: [],
value: [],
}
}
}

In your case, selected item is stored in value because that is what you specified in v-model:
<span>{{ selected }}</span>
<v-select
v-model="value"
:items="data"
item-text="data_name"
item-value="id"
/>
data: () => ({
data: [
{id: 0, data_name:'Apples'},
{id: 1, data_name:'Apricots'},
{id: 2, data_name:'Avocado'},
{id: 3, data_name:'Bananas'}
],
value: null,
}),
computed: {
selected () {
return this.data.find(item => item.id === this.value)
}
}
Since you specified item-value="id" you are getting the id. If you only need data_name you can specify item-value="data_name" to begin with. And then you have the text stored in the value without doing anything:
<span>{{ value }}</span>
<v-select
v-model="value"
:items="data"
item-text="data_name"
item-value="data_name"
/>

Using Vue multiselect to change Algolia index

I currently have a page where I'm able to switch Algolia indices with this:
<template>
<button #click="selectedIndex = a">List A</button>
<button #click="selectedIndex = b">List B</button>
<A v-if="selectedIndex === a" />
<B v-if="selectedIndex === b" />
</template>
<script>
import A from '#/A.vue';
import B from '#/B.vue';
export default {
components: {
A,
B
},
data() {
return {
selectedIndex: `a_${this.$root.index}`,
query: ''
};
},
computed: {
a() {
return `a_${this.$root.index}`;
},
b() {
return `b_${this.$root.index}`;
}
}
};
</script>
This is in a file called Index.vue. The different indices are in files A.vue and B.vue.
But now I need to be able to do the same content switching using a vue-multiselect in A.vue and B.vue.
Currently in A.vue, I have
<template>
<ais-instant-search
:search-client="searchClient"
:index-name="a"
:routing="routing"
>
<multiselect
v-model="selectedIndex"
:options="switcherOptions"
:searchable="false"
:close-on-select="true"
:show-labels="false"
placeholder="Choose"
>
<template slot="singleLabel" slot-scope="{ option }">
{{ option.text }}
</template>
<template slot="option" slot-scope="{ option }">
{{ option.text }}
</template>
</multiselect>
</ais-instant-search>
</template>
export default {
components: {
Multiselect
},
data() {
searchClient: algoliasearch(window.algolia.id, window.algolia.key),
selectedIndex: { value: 'a', text: 'List A' },
switcherOptions: [
{ value: 'a', text: 'List A' },
{ value: 'b', text: 'List B' }
]
};
},
};
What I don't know how to do now is send the value from the multi-select from A.vue back up to Index.vue where the different indices are defined.
First observation that I have, in your A.vue you are binding variable named a to your index, but do not have a defined in your data, same thing for routing.
What is the point of computed properties a and b, they are just returning strings, with do not do any computing, this could probably be defined in data:
data() {
return {
selectedIndex: 'a_index',
query: '',
a: 'a_index',
b: 'b_index',
};
},
Are A.vue and B.vue identical components? If only bindings are different, you can probably combine them into one component, and just pass different props to them. Hard to know for sure without seeing complete code.
So one way of doing this is emitting events from child to parent components. Documentation reference: https://vuejs.org/guide/essentials/event-handling.html
On your multiselect component add #select="$emit("indexSelected", selectedIndex)"
Like so:
<multiselect
v-model="selectedIndex"
:options="switcherOptions"
:searchable="false"
:close-on-select="true"
:show-labels="false"
placeholder="Choose"
#select="$emit("indexSelected", selectedIndex)"
>
This will emit event with name of indexSelected and included selectedIndex value in its payload.
Then in Index.vue you need to add these event listeners to both A and B Components:
<A v-if="selectedIndex === a" #indexSelected="selectedIndex = $event.value === 'a' ? 'a_index' : 'b_index'" />
<B v-if="selectedIndex === b" #indexSelected="selectedIndex = $event.value === 'a' ? 'a_index' : 'b_index'" />
Or if you would like cleaner template you can create a method:
methods: {
updateSelectedIndex(event){
this.selectedIndex = event.value === 'a' ? 'a_index' : 'b_index';
}
}
And then update template to:
<A v-if="selectedIndex === a" #indexSelected="updateSelectedIndex" />
<B v-if="selectedIndex === b" #indexSelected="updateSelectedIndex" />
EDIT:
I think this is kind of what you are looking for(reading between the lines lol), this rolls Index.vue, A.vue, B.vue into one component, because what you are trying to achieve is a lot simpler this way IMO. Obviously your actual app is more complex, so apply this as needed.
IndexAB.vue would look like this, values replaces with algolia demo, so substitute as needed:
<template>
<div>
<p>
<strong>Changing Index with buttons: </strong>
<button
v-for="option in searchIndexOptions"
:key="option.value"
#click="searchIndexName = option"
>
{{ option.text }}
</button>
</p>
<ais-instant-search
:search-client="searchClient"
:index-name="searchIndexName.value"
>
<p>
<strong>Changing Index with vue-multiselect: </strong>
<VueMultiselect
v-model="searchIndexName"
:options="searchIndexOptions"
:searchable="false"
:close-on-select="true"
track-by="value"
label="text"
placeholder="Change Search Index Here"
>
<template v-slot:singleLabel="{ option }">
<strong>{{ option.text }}</strong>
</template>
<template v-slot:option="{ option }">
<strong>{{ option.text }}</strong>
</template>
</VueMultiselect>
</p>
<ais-search-box />
<ais-hits>
<template v-slot:item="{ item }">
<h2>{{ item.name }}</h2>
</template>
</ais-hits>
</ais-instant-search>
</div>
</template>
<script>
import VueMultiselect from "vue-multiselect";
import algoliasearch from "algoliasearch/lite";
import "instantsearch.css/themes/satellite-min.css";
import "vue-multiselect/dist/vue-multiselect.css";
export default {
name: "IndexAB",
components: { VueMultiselect },
data: () => ({
searchClient: algoliasearch("latency", "6be0576ff61c053d5f9a3225e2a90f76"),
searchIndexName: { value: "instant_search", text: "List A" }, // Defaults to instant_search/List A
searchIndexOptions: [
{ value: "instant_search", text: "List A" },
{ value: "airbnb", text: "List B" },
{ value: "airports", text: "List C" },
],
}),
};
</script>
And sandbox: https://codesandbox.io/s/compassionate-ptolemy-9ljmhh?file=/src/components/IndexAB.vue
I had started with Vue 3 sandbox, so few things will be sligtly different(like import of vue-multiselect, and v-slot syntax)

Pass component as prop in Vue JS

Intro: I am exploring Vue Js and got stuck while trying to make a dynamic data table component the problem I am facing is that I cannot pass a component via props and render it inside a table.
Problem: So basically what I am trying to do is to pass some custom component from headers prop in v-data-table such as:
headers = [
{ text: 'Name', value: 'name' },
{
text: 'Phone Number',
value: 'phone_number',
render: () => (
<div>
<p>Custom Render</p>
</div>
)
},
{ text: 'Actions', value: 'actions' }
]
So from the code above we can see that I want to render that paragraph from the render function inside Phone Number header, I did this thing in React Js before, but I cannot find a way to do it in Vue Js if someone can point me in the right direction would be fantastic. Thank you in advance.
You have 2 options - slots and dynamic components.
Let's first explore slots:
<template>
<v-data-table :items="dataItems" :headers="headerItems">
<template slot="item.phone_number" slot-scope="{item}">
<v-chip>{{ item.phone_number }}</v-chip>
</template>
<template slot="item.company_name" slot-scope="{item}">
<v-chip color="pink darken-4" text-color="white">{{ item.company_name }}</v-chip>
</template>
</v-data-table>
</template>
The data table provides you slots where you can customize the content. If you want to make your component more reusable and want to populate these slots from your parent component - then you need to re-expose these slots to the parent component:
<template>
<v-data-table :items="dataItems" :headers="headerItems">
<template slot="item.phone_number" slot-scope="props">
<slot name="phone" :props="props" />
</template>
<template slot="item.company_name" slot-scope="props">
<slot name="company" :props="props" />
</template>
</v-data-table>
</template>
If you don't know which slots will be customized - you can re-expose all of the data-table slots:
<template>
<v-data-table
:headers="headers"
:items="items"
:search="search"
hide-default-footer
:options.sync="pagination"
:expanded="expanded"
class="tbl_manage_students"
height="100%"
fixed-header
v-bind="$attrs"
#update:expanded="$emit('update:expanded', $event)"
>
<!-- https://devinduct.com/blogpost/59/vue-tricks-passing-slots-to-child-components -->
<template v-for="(index, name) in $slots" v-slot:[name]>
<slot :name="name" />
</template>
<template v-for="(index, name) in $scopedSlots" v-slot:[name]="data">
<slot :name="name" v-bind="data" />
</template>
<v-alert slot="no-results" color="error" icon="warning">
{{ $t("no_results", {term: search}) }}"
</v-alert>
<template #footer="data">
<!-- you can safely skip the "footer" slot override here - so it will be passed through to the parent component -->
<table-footer :info="data" #size="pagination.itemsPerPage = $event" #page="pagination.page = $event" />
</template>
</v-data-table>
</template>
<script>
import tableFooter from '#/components/ui/TableFooter'; // you can safely ignore this component in your own implementation
export default
{
name: 'TeacherTable',
components:
{
tableFooter,
},
props:
{
search:
{
type: String,
default: ''
},
items:
{
type: Array,
default: () => []
},
sort:
{
type: String,
default: ''
},
headers:
{
type: Array,
required: true
},
expanded:
{
type: Array,
default: () => []
}
},
data()
{
return {
pagination:
{
sortDesc: [false],
sortBy: [this.sort],
itemsPerPageOptions: [25, 50, 100],
itemsPerPage: 25,
page: 1,
},
};
},
watch:
{
items()
{
this.pagination.page = 1;
},
sort()
{
this.pagination.sortBy = [this.sort];
this.pagination.sortDesc = [false];
},
}
};
</script>
Dynamic components can be provided by props:
<template>
<v-data-table :items="dataItems" :headers="headerItems">
<template slot="item.phone_number" slot-scope="{item}">
<component :is="compPhone" :phone="item.phone_number" />
</template>
<template slot="item.company_name" slot-scope="{item}">
<component :is="compCompany" :company="item.company_name" />
</template>
</v-data-table>
</template>
<script>
export default
{
name: 'MyTable',
props:
{
compPhone:
{
type: [Object, String], // keep in mind that String type allows you to specify only the HTML tag - but not its contents
default: 'span'
},
compCompany:
{
type: [Object, String],
default: 'span'
},
}
}
</script>
Slots are more powerful than dynamic components as they (slots) use the Dependency Inversion principle. You can read more in the Markus Oberlehner's blog
Okay, I don't believe this is the best way possible but it works for me and maybe it will work for someone else.
What I did was I modified the headers array like this:
headers = [
{ text: 'Name', align: 'start', sortable: false, value: 'name' },
{
text: 'Phone Number',
key: 'phone_number',
value: 'custom_render',
render: Vue.component('phone_number', {
props: ['item'],
template: '<v-chip>{{item}}</v-chip>'
})
},
{ text: 'Bookings', value: 'bookings_count' },
{
text: 'Company',
key: 'company.name',
value: 'custom_render',
render: Vue.component('company_name', {
props: ['item'],
template:
'<v-chip color="pink darken-4" text-color="white">{{item}}</v-chip>'
})
},
{ text: 'Actions', value: 'actions', sortable: false }
]
And inside v-data-table I reference the slot of custom_render and render that component there like this:
<template v-slot:[`item.custom_render`]="{ item, header }">
<component
:is="header.render"
:item="getValue(item, header.key)"
></component>
</template>
To go inside the nested object like company.name I made a function which I called getValue that accepts 2 parametes, the object and the path to that value we need which is stored in headers array as key (ex. company.name) and used loadash to return the value.
getValue function:
getValue (item: any, path: string): any {
return loadash.get(item, path)
}
Note: This is just the initial idea, which worked for me. If someone has better ideas please engage with this post. Take a look at the props that I am passing to those dynamic components, note that you can pass more variables in that way.

Vue-multiselect prevent selecting any items when using Single select (object)

I'm using Vue-multiselect 2.1.4
It works like a charm when I use single select with array options. But in case of using single select with array of objects, all items are green and they are not selectable! (They have "is-selected" class)
To clarify the problem, I used the sample code from the project website and replace the options with my data.
<multiselect v-model="value" deselect-label="Can't remove this value"
track-by="name" label="name" placeholder="Select one"
:options="options" :searchable="false" :allow-empty="false">
<template slot="singleLabel" slot-scope="{ option }">
<strong>{{ option.name }}</strong> is written in
<strong> {{ option.language }}</strong>
</template>
</multiselect>
const config = {
data() {
return {
value: null,
options: []
}
},
async mounted() {
await this.getTerminals();
},
methods: {
async getTerminals() {
await window.axios.get("/api/Operation/GetTerminals")
.then(resp => {
this.$data.options = resp.data;
})
.catch(err => {
console.error(err);
});
},
}
};
const app = Vue.createApp(config);
app.component('Multiselect', VueformMultiselect);
app.mount('#app');
In case of array of objects, first you need to populate the values in object and then push the object in options array. And there will be few changes in the template as well. For example if your object is like this, following will work:
data(){
return{
value: null,
option: {
value: "",
name: "",
icon: "",
},
options: [],
}
},
methods: {
getData(){
//call your service here
response.data.list.forEach((item, index) => {
self.option.value = item.first_name + item.last_name;
self.option.name = item.first_name + " " + item.last_name;
self.option.icon =
typeof item.avatar !== "undefined" && item.avatar != null
? item.avatar
: this.$assetPath + "images/userpic-placeholder.svg";
self.options.push({ ...self.option });
});
}
}
Then in the template fill the options like this:
<Multiselect
v-model="value"
deselect-label="Can't remove this value"
track-by="value"
label="name"
:options="options"
:searchable="false"
:allow-empty="false"
>
<template v-slot:singlelabel="{ value }">
<div class="multiselect-single-label">
<img class="character-label-icon" :src="value.icon" />
{{ value.name }}
</div>
</template>
<template v-slot:option="{ option }">
<img class="character-option-icon" :src="option.icon" />
{{ option.name }}
</template>
</Multiselect>
Call your getData() function in created hook.
For me the solution was to use the "name" and "value" keys for my object. Anything else and it doesn't work (even if they use different keys in the documenation). This seems like a bug, but that was the only change I needed to make.

vue: using a v-for for semi-dynamic object

I have a list of ID's from the vuex store.
idList = [23,54,66]
I want to use a v-for to iterate that list and then create a new data model that looks like this below but unsure how to set up my v-model code:
newData = {
[
{
id: 23,
url: // based off v-text-field,
key: //based off v-text-field
},
{
id: 54,
url: // based off v-text-field,
key: //based off v-text-field
},
{
id: 66,
url: // based off v-text-field,
key: //based off v-text-field
},
]
}
my code so far:
<v-checkbox
class="stream-targets"
v-for="(target,index) in idList"
v-model="locationTarget"
:value="target"
>
<template v-slot:label>
<span class="check-text" v-model='???'>{{ target}} [{{ target}}]</span>
<v-text-field placeholder="URL" v-model='??'></v-text-field>
<v-text-field placeholder="Key" v-model='??'></v-text-field>
</template>
</v-checkbox>
U nead something like this:
in vuex:
state: {
idList: [23,54,66]
},
in component and in created() method:
var idList = this.$store.state.idList;
idList.forEach(el => {
this.newData.push({
id: el,
url: '',
key: ''
});
});
and in component:
<v-checkbox
class="stream-targets"
v-for="(target,index) in newData"
:key="index"
v-model="locationTarget"
:value="target"
>
<template v-slot:label>
<!-- <span class="check-text" >{{target.id}}</span> -->
<v-text-field placeholder="URL" v-model='target.url'></v-text-field>
<v-text-field placeholder="Key" v-model='target.key'></v-text-field>
</template>
</v-checkbox>

Recode a html <select> and <option> into vuetify <v-select>

Quantity:
<select>
<option value="0">0</option>
<option
:value="x"
v-for="x in product.stock_count"
:key="x"
:selected="x == product.quantity"
>{{x}}</option>
</select>
Here, product.stock_count is holding the integer value for the total number of stock amount, and product.quantity is the selected quantity which is to be updated. I want to build the same selection
control with vuetify v-select
https://vuetifyjs.com/en/components/selects#api
Not using product object directly in the v-select, using an object property product.stock_count which has an integer value (eg. 5), now I want the v-select to have values from 1 to 5. And 0 when the product.stock_count returns 0.
<v-select :items="items"></v-select>
<script>
export default {
data: () => ({
//items: [from zero to product.stock_count],
}),
}
</script>
kindly help me out.
<template>
<v-select
v-model="selected"
:items="products"
label="Standard"
item-text="name"
item-value="id"
return-object
></v-select>
</template>
<script>
export default {
data: () => ({
products: [],
selected:{id:1,stock_count:5,quantity:5,name:'Product 1'}
}),
methods:{
getproductAPI(){
this.products= [
{
id:1,
stock_count:5,
quantity:5,
name:'Product 1'
},
{
id:2,
stock_count:10,
quantity:10,
name:'Product 2'
},
]
},
},
mounted(){
this.getproductAPI()
}
}
</script>
if your using object
try this:
<v-select
:items="items"
v-model="selection"
>
</v-select>
...
selection: 0
If you have other data (which it seems so based on your product. stock_count/quantity that you want to display you can use the item-text, item-value props.
