I need to do simple drop-down list (aka select) with Vue Element. I need to put selected value id in variable, but I can't understand how to do it with Element. I know how to do it in pure Vue, but it's do not working with Element.
Here is my code https://jsfiddle.net/dxh2mbkv/
<el-select clearable placeholder="Select" class="SelectFullWidth" >
<el-option
v-for="item in people"
:value="item.name" >
</el-option>
</el-select>
I need to get selected id in variable.
There is small issue with example. It's now working, because I have never used Vue Element with jsfiddle.
Pure Vue solution that I need reimplement in Vue element https://jsfiddle.net/mani04/3x0z3vzk/
I have modified your fiddle to make it work:
https://jsfiddle.net/dxh2mbkv/33/ (if you can't see labels in dropdown it seems to be jsfiddle issue, when you open developer tools in your browser or shrink your screen width, they should appear)
<el-select clearable placeholder="Select" class="SelectFullWidth" v-model="selectedPerson">
<el-option
v-for="item in people"
:key="item.key"
:label="item.name"
:value="item.key" >
</el-option>
</el-select>
Key: {{selectedPerson}}
What I did was I added v-model="selectedPerson" to el-select, changed your :value in el-option from item.name to item.key and added :label="item.name" to display option labels properly. And since your selectedPerson binds to a number, I changed it's default value to null.

I am working on a Vue app made with element UI and I have a bunch of el-select whose el-options need to have default values, meaning the form select fields already have one option pre-selected (of course the user can still choose other options).
I cannot find any attribute in the official doc https://element.eleme.io/#/en-US/component/select#select
But there should be a way to achieve this right?
This is my code
<el-form-item label="some label" prop="someprop">
<el-select v-model="form.status" filterable clearable>
<el-option
v-for="(item, index) in config.status"
:key="index"
:label="item"
:value="index"
how to have default option here??
>
</el-option>
</el-select>
</el-form-item>
Just put in the form.status the indexes that should be pre-selected. Vue will take care of the rest.
data(){
return {
form: { status: ['thisWillBePreSelected'], },
}
}
I have a parent component, SearchComponent:
<template>
<div>
<div class="relative pl-8 pr-10 rounded bg-white border focus-within:bg-white focus-within:ring-1">
<input v-focus #keyup.escape="clearSearch" #keyup="doSearch" v-model="searchTerm"
class="w-full ml-4 h-12 pl-1 text-gray-700 text-lg rounded-full border-0 bg-transparent focus:outline-none placeholder-gray-400"
placeholder="Search..." autocomplete="off">
</div>
<ul class="bg-white mt-4">
<quick-search-item v-for="item in searchResults" :key="item.id" :item-data="item.itemData">
</quick-search-item>
</ul>
</div>
</template>
This is responsible for receiving user input and getting results from an ajax call, handling errors etc. and generating the result list.
What I'd like to do is to make this generic so that instead of having a quick-search-item child component I can pass in different types of child component (like car-search-item, person-search-item etc.) depending on the context of where the user is in the app and what they're searching for
I've read a number of tutorials and I couldn't find quite what I'm trying to do. This may mean I'm approaching this in the wrong way - but if anyone could point me in the right direction, or has a better approach, I'd be very grateful.
Thanks,
Lenny.
I would try to make use of the <slot> element. Check out the documentation here
<parent-component>
<slot></slot>
</parent-component>
Hope this can put you on the right path.
Schalk Pretorius was quite right: slots are the answer to this, specifically scoped slots. I found the Vue docs a little confusing as it refers to getting data from the child component and I wanted to do it the other way around, so as an aide memoire for myself and to help anyone else here's what I did:
In my parent component I defined the slot like this:
<slot name="results" v-bind:items="searchResults">
</slot>
The v-bind binds searchResults (a data item in the parent component) to the value 'items'. 'items' then becomes available in the slot.
In my child component I have a simple property setup called items:
props: {
items: {type: Array},
},
Then to hook it all together in my Blade file I did this:
<search-component endpoint="{{ route('quick_search.index') }}">
<template v-slot:results="props">
<food-results :items="props.items">
</food-results>
</template>
</search-component>
This creates the search-component. Inside that -as I'm using named slots - we need a template and use v-slot to tell it which slot to use (results), then the ="props" exposes all the properties we've defined on that slot (in this case just one, 'items').
Inside the template we put our child component and then we can bind items to props.items which will be the searchResults in our parent component.
I'm happy to have this working and I can now create lots of different results components while reusing the search component - and at least I learnt something today!
Cheers,
Lenny.
I have built a user-defined component (async-select) on top of another component (vue mutliselect) like this:
https://jsfiddle.net/2x7n4rL6/4/
Since the original vue-multiselect component offers a couple of slots, I don't want to loose the chance to use them. So my goal is to make these slots available from inside my custom component. In other words, I want to something like this:
https://jsfiddle.net/2x7n4rL6/3/
But that code oes not work.
However, if I add the slot to the child component itself, it works just fine (which you can see from the fact that options become red-colored).
https://jsfiddle.net/2x7n4rL6/1/
After surfing the web, I have come across this article, but it does not seem to work
Is there any way in VueJS to accomplish this ?
Slots can be confusing!
First, you need a template element to define the slot content:
<async-select :value="value" :options="options">
<template v-slot:option-tmpl="{ props }">
<div class="ui grid">
<div style="color: red">{{ props.option.name }}</div>
</div>
</template>
</async-select>
Then, in the parent component, you need a slot element. That slot element itself can be inside of another template element, so its contents can be put in a slot of its own parent.
<multiselect
label="name"
ref="multiselect"
v-model="localValue"
placeholder="My component"
:options="options"
:multiple="false"
:taggable="false">
<template slot="option" slot-scope="props">
<slot name="option-tmpl" :props="props"></slot>
</template>
</multiselect>

I am using a plugin called Vue-Multiselect and have it working pretty good on my app. However, there is a functionality in the plugin that I do no want. How can I safely remove it?
Let me explain: CodeSandBox Collaboration Editor .
Note: To see this flow in action, choose EDIT next to ACME Widget and then search for an on existent user in the multiselect input box.
When a user is searched for in the multiselect input box, and if a match is found, the match pops up for the user to select. That is good. However, when a user is NOT found, there's a placeholder text that says the following: Press enter to create a tag . I do NOT want to give my users the ability to create new tags/options if the option does not exist. How can I remove that functionality from this component?
Here is my multi-select component code:
<multiselect
id="customer_last_name_input"
v-model="values"
:options="options"
label="lastname"
placeholder="Select or search for an existing customer"
track-by="uid"
:loading="isLoading"
:custom-label="customerSelectName"
aria-describedby="searchHelpBlock"
selectLabel
:multiple="true"
:taggable="true"
>
<template
slot="singleLabel"
slot-scope="props"
>{{ props.option.lastname }}, {{props.option.firstname}}</template>
<template slot="option" slot-scope="props">
<strong>{{ props.option.lastname }}</strong>
, {{ props.option.firstname }} —
<small>{{ props.option.email }}</small>
</template>
<!-- <template slot="noResult">Looks like this customer doesn't exist yet.<button class="btn btn-primary" type="button" #click="addCustomer">Add Customer</button></template> -->
</multiselect>
I found the answer. I simply remove the taggle=true prop from the multiselect component.
I've el-select option with photo, in option i can get photo variable but in default value i can't get defult value with photo.
can you help me?
Expected: default value is McDonald (photo + label)
here my code:
<el-select v-model="value" placeholder="Select">
<el-option v-for="item in outlet" :key="item.value" :label="item.label" :value="item.value">
<img :src="item.photo"> {{ item.label }}
</el-option>
</el-select>
and here is my fiddle:
https://jsfiddle.net/dede402/L4y8zw1e/10/
The selected value template and options templates are differents. el-select allow you to define a prefix slot for the selected template, take a look at : https://jsfiddle.net/budgw/L4y8zw1e/36/
Note that I change your el-select in order to use directly an object as selected value. In that case you have to specify the value-key on el-select.
